Sweet and Salty Nut Bars

Sweet and Salty Nut Bars will be the latest and greatest addition to your holiday sweets menu. Made with a buttery shortbread crust, soft chocolate-peanut butter center, and topped with salty mixed nuts – they hold something for everyone!

Sweet and Salty Nut Bars

No doubt about it, these Sweet and Salty Nut Bars are perfect for the holidays! A cross between a cookie bar and a candy bar, they’re sure to be welcome on either cookie or candy tray. A crumbly shortbread crust is the base for a nutty chocolate-peanut butter fudge center. Then, it’s topped with more roasted, salted, mixed nut goodness. It’s the best of salty and sweet together.

Sweet and Salty Nut Bars

Make the Shortbread Crust

Begin the crust with 1/2 cup butter, brown sugar and flour. It’s such a simple combination of ingredients that make magic when mixed together. Start with a wooden spoon, and when the mixture clumps, use your hands to knead the mixture together.

After everything is combined and crumbly, pour the mixture into the bottom of a parchment-lined 8×8 inch square baking pan. Tamp the crust down into the pan with your palms or with the bottom of a flat measuring cup. Bake it for 12 minutes in a preheated 350F oven, and then cool completely.

Make the Smooth Peanut Butter-Chocolate Filling

Next, prepare the filling. It’s such an easy fix! Combine sweetened condensed milk, semisweet chips, and peanut butter. Heat on the stove top and stir until smooth.

When the mixture is smooth, add in mini marshmallows. Stir while cooking over medium heat. It will take a few minutes for the marshmallows to melt and incorporate. Just keep stirring!

Add Salty Mixed Nuts

Stir in a cup of roasted, salted mixed nuts. Don’t go for ‘lightly salted’, we’re looking for well-seasoned mixed nuts with roasty flavor. The Planter’s mix I used has peanuts, almonds, cashews, and pistachios (similar here).

Pour the chocolaty mixture over the prepared, cooled shortbread crust. It will begin to set up quickly, so smooth the top as best you can and then…

Sprinkle the nuts evenly over the surface of the fudgy filling.

Even the Top

Using flat palms, or the bottom of a flat measuring cup, tamp the nuts down into the chocolate filling. Allow the candy to set until completely cool and firm. You can also refrigerate the pan to speed setting.

Remove the slab from the pan by lifting it out by the parchment paper. Then cut it into squares. I portioned generous slices (16 total), however, these are rich. You could easily cut them smaller to double the yield.

Salty-sweet-crunchy-nutty – what’s not to love? These travel well, and can be easily be packaged for gift giving. While they’re not exactly cookies, I think they’d be welcome at any cookie swap!

These bars are a harmonious blend of sweet and salty, featuring a buttery shortbread base, luscious chocolate-peanut butter filling, and a generous sprinkle of roasted, salted mixed nuts on top. With their dual personality as both a cookie and a candy, they’re the ideal treat for holiday dessert gifts or gatherings.
Please note that salted butter is used in the shortbread crust. Unsalted butter can be used in its place. If you do this, add a pinch of fine grain salt to the flour mixture.

These look wonderful! I am definitely going to have to add to my holiday cookie platter this year. I am just wondering about the paper cups you used – I have looked for square ones and haven’t been able to find them – do you happen to have a link for yours?
