Ingredients

Scale

Banana Bread Cookies

  • ½ cup unsalted butter (softened)
  • ¾ cup granulated sugar
  • ¼ cup brown sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 cup mashed ripe banana (about 2 medium bananas)
  • 1½ cups all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon baking powder
  • ½ teaspoon salt
  • 1 teaspoon cinnamon

Frosting

  • ½ cup butter (softened)
  • ½ cup brown sugar (packed)
  • 1½ cups powdered sugar
  • 2 tablespoons milk or cream
  • 1 teaspoon vanilla extract
  • Pinch of salt

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper to prevent sticking.
  2. Cream Butter and Sugars: In a large mixing bowl, beat together the softened butter, granulated sugar, and brown sugar until the mixture is light and fluffy, ensuring a smooth base for the cookies.
  3. Add Wet Ingredients: Mix in the egg, vanilla extract, and mashed ripe bananas. The mixture might appear a bit separated at this stage, which is completely normal and does not affect the final texture.
  4. Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, baking powder, salt, and cinnamon. Gradually add these dry ingredients to the wet mixture, stirring just until combined to avoid overmixing.
  5. Shape and Bake Cookies: Scoop tablespoon-sized portions of the batter onto the prepared baking sheets, spacing them evenly. Bake in the preheated oven for 10 to 12 minutes until the cookies are set but still soft. Remove and allow them to cool completely on a wire rack.
  6. Prepare Frosting: While the cookies cool, beat the softened butter and packed brown sugar together for about 2 minutes until fluffy. Add powdered sugar, milk or cream, vanilla extract, and a pinch of salt, then beat until smooth and creamy.
  7. Assemble Sandwich Cookies: Spread a generous amount of frosting on the flat side of half the cooled cookies. Top each with another cookie, pressing gently to form sandwich cookies. Serve or store as desired.

Notes

  • Ensure bananas are very ripe for maximum sweetness and moisture.
  • Do not overmix after adding flour to keep cookies tender.
  • Cookies should be completely cooled before frosting to prevent melting.
  • Store sandwich cookies in an airtight container at room temperature for up to 3 days.
  • For a dairy-free version, substitute butter and milk with non-dairy alternatives.
