How to Make Peanut Butter Brownie Swirl Cookies
Step 1: Make the Peanut Butter Dough
In a bowl, beat the peanut butter, softened butter, and brown sugar until light and fluffy. Follow these steps:
1. Add in 1 egg and 1 tsp vanilla extract; mix well.
2. In a separate bowl, whisk together 1 cup flour, 1/2 tsp baking soda, and 1/4 tsp salt.
3. Gradually combine the dry ingredients with the wet mixture until just combined.
Step 2: Make the Brownie Dough
Prepare the brownie dough while the peanut butter dough chills. Here’s how:
1. In another bowl, whisk together 1/2 cup melted butter and 1 cup white sugar.
2. Mix in 1/3 cup cocoa powder until smooth, then add in 1 egg and 1 tsp vanilla extract; stir well.
3. Fold in 3/4 cup flour, 1/4 tsp baking powder, 1/4 tsp salt, and finally, add in 1/2 cup chocolate chips until no dry streaks remain.
Step 3: Chill Both Doughs
Chill both doughs for about 30 minutes to firm them up before shaping.
Step 4: Scoop and Swirl
Scoop out 1-2 tbsp portions of each dough and place them side by side on a parchment-lined baking sheet. Use a toothpick or skewer to gently swirl the doughs together in a marble pattern for that signature look.
Step 5: Bake
Preheat your oven to 350°F (175°C). Bake the cookies for about 9-11 minutes or until their tops are lightly crackly while the edges are just set. The centers should remain soft.
