The combination of banana, miso, and biscoff in these Banana Miso Biscoff cookies is heavenly. A rich, decadent chocolate chip cookie dough is flavored with smashed banana, a dollop of white miso, and a swirl of biscoff cookie butter. Included in this post are tips on how to make the most consistent cookies every time.
Preheat the oven to 350 degrees F (177 degrees C).
First, brown ½ cup of unsalted butter. Melt the butter over medium heat until fully melted. Lower to medium low and cook until brown bits start to appear. Remove from the heat and set aside.
Mix together 1 ¼ cup of all purpose flour, ½ tsp of baking soda, and ¼ tsp of salt. Set aside.
Combine browned butter and 1 cup of light brown sugar in a bowl. Whisk until combined.
Add the egg yolk and whisk until combined.
Add ½ tsp of vanilla extract, 1 small mashed banana, and 1 tbsp of white miso. Whisk until light and fluffy (see image for reference). Make sure to use only 1/4 cup of mashed banana. Otherwise, the cookie will become cakey.
Combine the wet ingredients with the dry ingredients from step 3. Mix until just combined.
Finally, add ½ cup of dark chocolate. Mix until just combined.
Dollop ¼ cup of biscoff cookie butter onto the dough, divided into 4 equal spoonfuls. Using a knife, swirl the cookie butter into the dough.
Prep 2 baking sheets by covering them with parchment paper. Using a medium cookie scoop (#20 cookie scoop), scoop the dough onto the prepped baking sheets.
Bake for 11-13 minutes until the edges are slightly brown.
Cool for 5-10 minutes on the baking sheet before transferring to a cooling rack to cool completely.
Notes
Store cookies in an airtight container at room temperature for up to 3 days.
