Matcha-Almond Layer Cake with Meringue Mushrooms


I've been having disorganized pantry shame for a few months now, so last Friday I decided to do something about it. I went in armed with a roll of garbage bags and an indiscriminate attitude (let's get rid of it all!), but soon found that my pantry was more like an archaeological dig into the past two years of my life.

Cake boards and tuile stencils (once lost) were found flattened against a wall. A binder of dessert sketches and scribbles lay open with bent pages under a pile of cookbooks. A grocery bag held gold plastic eggs for an Easter post that never happened. Flattened cupcake papers would surface every now and again, along with stocking stuffers that never made it to the mantel at Christmastime. Last unearthed, a box of miscellany; cookie cutters, ribbon, rock candy and chocolate transfer sheets.


After everything was considerably more organized (though not much diminished), I pulled out a chocolate transfer sheet that had caught my eye. The delicate pattern was almost indistinguishable with airy spirals and green flecks... but what I managed to see reminded me a little of mushroom spore prints - an art-slash-science project I'd had fun with as a kid.

That's all it took. I spent the rest of the day with my head in the clouds. I was dreaming of my own species of mushroom (Boletus saccharo - sugar mushroom?) and sketching ideas for a cake teeming with them.



It's been ages since I've made meringue mushrooms. I first made them for this Buche de Noel, in my early blogging days, but who says you have to wait until Christmas to make these guys? They are delightful any time of year!


It's also been a while since I've made anything with matcha tea powder, which is surprising because it's one of my favorite ingredients of all time. It's really perfect for this cake - not bitter at all, especially when paired with almond - and with just a hint of earthiness. I whipped these flavors into silky Swiss buttercream to coat layers upon layers of almond-scented butter cake.


If you're a newbie at using transfer sheets, you can find additional instructions here and here. I usually find my transfer sheets at Fancy Flours, though some may be found locally at specialty cake shops.

I had so much fun immersing myself in every aspect of this cake, albeit the inspiration was a little weird and unconventional (spores, mushrooms... who makes a cake with that in mind?). In the end it turned out pretty cute and woodsy-looking, but above all - it's mighty tasty.

Matcha-Almond Layer Cake with Meringue Mushrooms
Yield: 8-10 servings
Recipes adapted from the SprinkleBakes book
Prep 2 hours 30 minutes; total time about 5 hours

Cake
1/4 pound (1 stick) butter, softened
1 3/4 cups (350g) sugar
3 eggs, at room temperature
2 teaspoons (8g) vanilla extract
1/2 teaspoon (2g) almond extract
2 1/4 cups (270g) all-purpose flour
3 1/2 teaspoons (10g) baking powder
1 teaspoon (7g) salt
1 1/4 cups (292g) full fat sour cream

Swiss buttercream frosting/ chocolate transfer
6 egg whites
1 cup (118g) sugar
Pinch of salt
1 1/4 pounds (5 US sticks) unsalted butter, cubed, at room temperature
2 teaspoons (8g) vanilla extract
1/2 teaspoon (2g) almond extract
1 tablespoon (10g) matcha green tea powder
1 1/2 tablespoons (22g) hot water
4 oz. semisweet chocolate chips
Chocolate transfer sheet of your choice

Meringue mushrooms
2 egg whites, at room temperature
1/4 teaspoon (1g)  cream of tartar
1/2 cup (100g) granulated sugar
4 oz. chocolate chips or candy coating
2 tablespoons (20g) cocoa powder
2 tablespoons (20g) matcha green tea powder
  1. Make the cakes. Preheat the oven to 350°F. Grease the bottom and sides of three 7-inch springform pans (if you don’t have 3, you can reuse the ones you have or use two 9-inch pans). Line the bottom and sides with parchment paper, and then grease the paper.
  2. In the bowl of a standing mixer fitted with the paddle attachment, cream the butter and sugar together. Add the eggs, vanilla and almond extracts, and beat until combined. Combine the flour, baking powder, and salt and add to the mixer bowl in three batches, alternating with the sour cream and beginning and ending with the flour mixture. Scrape down the bowl and beat on high speed for 3 minutes. Divide the batter evenly into pans, or if reusing a pan, fill each pan two-thirds full.
  3. Bake for 25 to 30 minutes, or until a toothpick comes out clean when inserted into the middle of the cakes. Let the cakes cool slightly in the pans. Remove and let them cool completely on a wire rack. Level cakes with a large serrated knife or cake leveler. Torte each cake so that there are six layers.
  4. For the matcha-almond Swiss buttercream, set a saucepan filled one-third full of water over medium-high heat and bring to a simmer.
  5. Whisk together the egg whites, sugar, and salt in a large heatproof bowl. Set over the simmering water and whisk until the mixture is hot to the touch and the sugar has dissolved.
  6. Transfer the mixture to the bowl of a stand mixer fitted with the whisk attachment.
  7. Beat on low speed for 2 minutes. Increase to medium-high until stiff peaks are formed.
  8. Continue beating at medium-high speed until the mixture is fluffy and has cooled (the mixing bowl should feel cool to the touch).
  9. Turn the mixer off and switch from the whisk attachment to the paddle. Turn the mixer on medium-low and add the butter, a few cubes at a time, beating until well incorporated before the next addition. The egg whites will deflate and thin with the first few additions – don’t let this discourage you – keep going.  It may also look curdled, but don’t fret. Beat on high speed when all the butter has been added. The mixture will thicken and become smooth after several minutes of beating. Beat in the vanilla and almond extracts.  Place matcha tea powder and hot water in a small bowl and stir until a smooth paste forms. If mixture is very thick, add additional hot water until it is very smooth but not too liquid. Add the matcha paste to the batter and beat until the frosting is completely smooth and consistently green.
  10. Reserve 1/4 cup frosting for later use. Place a cooled cake layer on a cake stand and top with 1/3 cup frosting; top with another cake layer and repeat frosting with remaining layers. Cover cake with a thin coat of frosting (crumb coat) and refrigerate until firm, about 15 minutes. Remove cake from refrigerator and coat cake in a thick even layer with the remaining frosting. Refrigerate until firm.
  11. For the chocolate transfer, measure and cut a 4x16-inch band from the transfer sheet. Place it smooth-side-down on a large piece of parchment (you should be able to feel the raised chocolate pattern on the side facing upward). Melt chocolate at 30 second intervals until it can be stirred smooth.  Place a large spoonful of melted chocolate at one short end of the cut transfer sheet band, and smooth it over using an off-set spatula. Try to smooth the chocolate over the entire area in one fluid stroke; this will decrease the chances of the pattern shifting. Holding the coated transfer sheet at both ends, press the middle of the sheet onto the cake and wrap the ends around the cake. Refrigerate until the chocolate is firm, about 15 minutes. Once the chocolate is firm, remove the acetate coating.  Measure and cut another piece of the transfer sheet to fill in the remaining gap. Coat with chocolate, and press onto cake as before. Let chill and remove acetate when the chocolate is firm.
  12. For the meringue mushrooms, prepare two baking sheets by lining them with parchment paper. Preheat the oven to 200 degrees.
  13. Place room temperature egg whites in the bowl of an electric mixer fitted with a whisk attachment. It is important that the bowl and whisk both be very clean, so that the egg whites whip properly. Begin beating the egg whites on medium speed. Once they are very frothy, stop the mixer and add the cream of tartar. Start the mixer again and continue to beat the egg whites. Once they form soft peaks, increase the speed to high and gradually add the sugar, a tablespoon at a time. Beat the whites until they are very shiny and hold stiff peaks, but are not dry or crumbly.
  14. Spoon the meringue into a large pastry bag fitted with a 1/2-inch round tip. First, pipe the mushroom caps: hold the pastry bag at a 90-degree angle about 1/2 inch from the parchment paper. Using firm and even pressure, squeeze out a round meringue disc about 2 inches in diameter and 1 inch high. Stop squeezing, then twist the bag and lift it from the meringue to get a clean break from the cap. Repeat in regular intervals on the baking sheet until you have approximately 2 dozen mushroom caps. The mushroom caps will most likely have peaks on top, so smooth the tops by wetting your index finger and lightly pressing the peaks down into the caps.
  15. Next, pipe the mushroom stems. Again position the bag perpendicular about 1/2-inch from the baking sheet. Begin squeezing the bag to form a 1-inch round base. Continue to squeeze as you slowly and evenly draw the bag up, then release pressure (causing a break) to form a tapering stem about 2 inches tall. The stems will have peaks on top, but do not smooth them down as before with the caps. Use the remaining meringue to pipe as many stems as possible—allow some stems to tilt and collapse to the side, these mushrooms will be applied to the side of the cake in a “climbing” manner.
  16. Bake the meringues at 200 degrees for about 90 minutes, turning them halfway through the cooking time to ensure an even bake. The meringues should be hard and dry to the touch, and you should be able to easily lift one from the parchment. Once the meringues are done, let them cool completely before assembling. If time allows, you can also turn off the oven and let them sit in the oven for several hours or overnight.
  17. To assemble the mushrooms, melt the chocolate in a small bowl in the microwave, stirring after every 30 seconds to prevent overheating. Use a toothpick to carve a small hole in the bottom of a mushroom cap. Dip the top (pointed end) of a stem in the chocolate, and stick the chocolate-covered stem top in the carved hole of the mushroom cap. Place the mushroom on a baking tray and leave to set, and repeat with remaining caps and stems.
  18. Place the cocoa and matcha powder in separate small bowls.  Dip the bottoms of the mushroom stems in the matcha powder, then in the cocoa; tap to remove excess powders. Load a dry pastry brush with the matcha powder and brush the caps. You may also use a sifter to sift matcha and cocoa over the mushrooms.
  19. Use the reserved 1/4 cup frosting to attach the mushrooms to the side of the cake. Group them together as tightly as possible.  Place a group of mushrooms standing upright on top of the cake. Randomly place one or two mushrooms away from the groups of mushrooms on top of the cake.
  20. Store cake loosely covered at room temperature for up to 24 hours. To increase longevity, store cake loosely covered in the refrigerator. Mushrooms will most likely wilt, but the cake will keep for a few days longer refrigerated. Bring to room temperature before serving.
Note: Mushrooms can be stored for up to a month in an airtight container in a cool, dry room. Humidity can make the mushroom soft and they will collapse. Mushrooms will become soft after 12 hours on the cake at room temperature, but they should still hold their shape relatively well.  Do not assemble mushrooms on cake more than 24 hours before serving.

  30. Gorgeous cake! As my family is Asian, we prefer the less sweet desserts that are usually flavored with coffee, black sesame, and especially matcha. Have you tried to make a matcha flavored gateau opera? It is quite delicious and a stunning cake to make. Another "odd" ingredient used in Asian baking is purple sweet potato. The color is absolutely beautiful, and I would love to see you create a masterpiece with its mild flavor.

  35. LOVE THIS CAKE! It's beautiful. Can't wait to try it out! A few questions:

    1) what kind of matcha do you have? I haven't used it before so I don't know much about what kind is best.
    2) do you know the name of the design of that transfer paper? I checked on fancy flours and I didn't see it.

    You're kind of my hero :) I've made almost 20 of your cakes and cookies and I've loved every one.

  36. Hi @thatpersonwhohatesblogs!

    I use Maeda-en culinary grade matcha. You can find it here. http://maeda-en.com/matcha/167-matcha-green-tea-powder.html#

    I can't seem to find that particular transfer sheet either. They often discontinue designs, so that might have happened. There are other designs that would work with this cake, though- like this wood grain (love!) http://www.fancyflours.com/product/Woodgrain-Brown-Chocolate-Transfer-Sheet/brown-patterned-chocolate-transfer-sheets

    or maybe even this bubble transfer sheet - http://www.fancyflours.com/product/Bubbles-Chocolate-Transfer-Sheet/gold-patterned-chcolate-transfer-sheets

    I'm so glad you've made my recipes and loved them! That makes me so happy!

  47. Made this cake with my mom the other day for her office "cake boss" competition and it blew them away. I added my own raspberry basil filling and instead of a chocolate transfer boarder we made an almond bark. It didn't turn out nearly as neat as yours, but we loved the overall effect. Thanks so much for sharing :)
