Ingredients

The following ingredients have 12 Servings
  • 4 oz unsalted butter
  • 3 oz peanut butter (about 1/3 cup)
  • 2 1/4 cups all-purpose flour
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • 1 cup brown sugar (packed)
  • 1/2 cup granulated sugar
  • 1 large egg yolk (at room temperature)
  • 1 tbsp vanilla extract
  • 1/2 cup banana ((mashed, ripe) from about 1 1/2 bananas)
  • 1 cup milk chocolate chips
  • 1/2 cup peanut butter chips

Instruction

  • Preheat your oven to 350 degrees Fahrenheit.
  • Combine the butter and the peanut butter in a large microwave-safe bowl, and microwave in 30-second intervals until the butter is melted. Stir the two together and set the bowl aside to cool to room temperature.
  • In a small separate bowl, whisk together the flour, baking soda, and salt.
  • Add both sugars to the bowl of melted butter and peanut butter, and whisk them together until the sugars are wet and everything is combined. Add the egg yolk and the vanilla extract, and whisk again until they’re incorporated. Add the mashed banana and whisk once more, stirring until everything is combined.
  • Whisking all the while, slowly add the dry ingredients. Once all the drys are added, switch to a spatula and stir everything together, scraping the bottom and sides of the bowl. Add the milk chocolate and peanut butter chips and stir until your dough is smooth and there are no dry spots of flour remaining.
  • Use a cookie scoop or tablespoon to drop balls of dough onto a parchment-lined baking sheet. Bake at 350 for 11-12 minutes, until golden around the edges and puffed and just set in the center. Once completely cool, store in an airtight container at room temperature for up to a week.
  • These are also an excellent base for ice cream sandwiches. If you want to do turn them into sandwiches, press a scoop of slightly softened ice cream on the bottom of a cookie, then press another cookie on top. Very gently squeeze them together, until the ice cream reaches the sides of the cookie. Roll the sides in sprinkles, nuts, or miniature chocolate chips. If you won’t be eating them immediately, wrap each sandwich individually in plastic wrap and store in the freezer.
