One of my all time favorite flavor combinations has to be chocolate with peanut butter, and these keto peanut butter cup bars perfectly encapsulate the flavors in one perfect, easy to make bar. Growing up, Reese’s peanut butter cups were my favorite candy, and peanut butter blossoms were my favorite Christmas cookie. So it only made sense that as an adult, I love creating new versions of chocolate + peanut butter recipes. If you’re a fellow chocolate peanut butter lover, you won’t be disappointed.

These bars pack in 6g of whole foods protein (no protein powder!), 5g of fiber, and just 185 calories per bar.

They look intricate, but are actually so simple to make with only 6 total ingredients.

You’ll need:

• peanut butter, of course. I like to use an unsweetened creamy peanut butter for these.
• granulated allulose sweetener (or other sugar-free sweetener, but I recommend allulose for optimal texture and appearance)
• baking soda
• egg
• sugar-free peanut butter cups (you can find these at the store, or make your own!)
• sugar-free chocolate chips, or chocolate bar, for melting

The peanut butter, sweetener, baking soda, and egg, combine to create a super simple, yet absolutely delicious peanut butter blondie-like texture as the base. Shortly after removing from the oven, while they’re still warm, you’ll then press your peanut butter cups into the surface of the peanut butter blondies.

Now, the best part is the peanut butter ganache topping. It’s simply peanut butter and sugar-free chocolate melted together and spread over the surface of the blondies, but it looks and tastes absolutely professional and gourmet. Then you’ll just let the ganache set, drizzle with extra peanut butter, and enjoy!

Ingredients

  

• 1 + 1/4 cup creamy peanut butter divided
• 3/4 cup granulated allulose
• 1/2 tsp baking soda
• 1 large egg
• 9 sugar-free peanut butter cups
• 1/2 cup sugar-free chocolate chips

Instructions

 

• Preheat oven to 350°F and line an 8x8-inch square baking pan with parchment paper.
• In a large bowl, combine 1 cup peanut butter, sweetener, and baking soda. Add egg and stir until combined. Spread evenly into lined baking pan, using damp fingers to spread if batter is too thick.
• Bake for 15-18 minutes, until golden brown. Immediately after removing from oven, press peanut butter cups into the surface of the cookie bars, so that the top of the peanut butter cups is level with the top of the bars. Allow to cool completely.
• Combine remaining 1/4 cup peanut butter and the chocolate chips in a microwave safe bowl, and microwave for 30-60 seconds until soft enough to stir. Stir together until smooth. Pour mixture over the cooled bars and spread evenly.
• Allow to cool until topping sets up. Feel free to refrigerate to speed up this process.
• Drizzle with extra peanut butter if desired. Slice, and enjoy!
