I am a sucker for ripe bananas so they don’t last long when I see them in our kitchen. I put them into breakfasts, desserts, and eat them solo as snacks. One of the favorite ways to use them is to turn them into a cookie sandwich.

What may surprise you is that the filling in this recipe is super light, not at all thick and heavy.

When I think back to all the dessert specials we have served at our restaurant the most popular have always been the ones that had a touch of familiarity. These cookies offer that and don’t require a long and envolved time commitment.

If you love the taste of bananas and chocolate, this recipe is perfect for you.

Banana Chocolate Sandwich Cookies Ingredients

  • 1 1/4 cups all-purpose flour (156g)
  • 1/4 cup unsweetened cocoa powder (25g)
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/2 cup unsalted butter, room temperature (113g)
  • 1/2 cup granulated sugar (100g)
  • 1/2 cup packed brown sugar (100g)
  • 1 large egg
  • 1 teaspoon vanilla extract (5ml)
  • 1 ripe banana (approximately 100g)
  • 1 cup powdered sugar (125g)

Banana Chocolate Sandwich Cookies Instructions

  1. Heat the oven to 350°F (175°C).
  2. Line two baking sheets with parchment so cleanup stays easy.
  3. Whisk the flour, cocoa powder, baking soda, and salt in a medium bowl until the color looks even. Set it aside.
  4. In a larger bowl, beat 1/2 cup butter with the granulated sugar and brown sugar until creamy, about 3 minutes.
  5. Add the egg and 1 teaspoon vanilla. Mix until everything looks smooth and fully combined.
  6. Tip the dry ingredients into the wet and mix just until you don’t see flour streaks. Over mixing makes tougher cookies so be careful.
  7. Scoop and roll into 1-inch balls, then space them about 2 inches apart on the baking sheets.
  8. Bake 8 to 10 minutes, until the edges look set and the tops feel barely firm.
  9. Let them cool on the pan for a few minutes, then move to a rack to cool completely.
  10. Mash the banana until it’s very smooth. A few lumps are fine, but smoother makes a prettier filling.
  11. Beat the remaining 1/4 cup butter with the mashed banana, powdered sugar, and the last 1/2 teaspoon vanilla until creamy. If it seems loose, add a little more powdered sugar, one spoon at a time.
  12. Spread about 1 tablespoon of filling on the flat side of half the cookies.
  13. Press the remaining cookies on top to make sandwiches, then set them aside for at least 30 minutes so the filling settles in and serve.
  14. Alternatively, you can store them in an airtight container at room temperature for up to 2 days.
