What You’ll Need

Gather these simple ingredients to get started on your delightful cookies:

  • 1/2 cup butter (softened)
  • 1/2 cup creamy peanut butter
  • 1/2 cup white sugar
  • 1/2 cup brown sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 2 cups all-purpose flour
  • 2 cups rolled oats
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3 medium ripe bananas (mashed)
  • 1 cup semisweet chocolate chips

Let’s Make It Together

  1. Preheat the oven to 375°F (190°C). Line a baking sheet with parchment paper.
  2. In a mixer, cream together the softened butter, peanut butter, white sugar, and brown sugar until fluffy and well-combined. The mixture should be light and airy—just like the cozy feeling you get while baking!
  3. Beat in the eggs one at a time, followed by the vanilla extract. Allow this creamy mixture to come together beautifully.
  4. In a separate bowl, mix the flour, oats, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, being careful not to overmix. This keeps your cookies tender!
  5. Fold in the mashed bananas and semisweet chocolate chips gently, making sure they’re evenly distributed throughout the cookie dough.
  6. Scoop generous tablespoonfuls of dough onto the prepared baking sheet, leaving about 2 inches between each scoop for spreading.
  7. Bake for about 12 minutes or until the edges are lightly browned and the cookies look set. Allow them to cool on a wire rack before serving.

Delicious Variations to Try

  • Nutty Surprise: Add 1/2 cup chopped walnuts or pecans to the batter for an extra nutty crunch.
  • Fruity Twist: Mix in 1/2 cup of dried cranberries or raisins for a chewy element of sweetness.
  • Spicy Kick: Sprinkle in a teaspoon of cinnamon or nutmeg for a warm, spiced flavor that complements the bananas perfectly.
  • Peanut Butter Swirl: To make them extra indulgent, drizzle a little extra peanut butter on top of the cookies before baking!

Chef Emma’s Helpful Tips

  • Make-Ahead: If you want to prepare in advance, the cookie dough can be refrigerated for up to two days or frozen for up to three months. Just thaw in the refrigerator before scooping and baking.
  • Ingredient Swaps: For a dairy-free option, substitute coconut oil for butter and use nut butter of your choice.
  • Storage: Once baked, store your cookies in an airtight container at room temperature for up to a week (if they last that long!).
  • Serving Suggestions: These cookies pair wonderfully with a glass of milk or a steaming cup of tea—ideal for cozy moments.
