These Chocolate Chip Banana Cookies are a soft, chewy fusion of banana bread and chocolate chip cookies, made in one bowl and ready in under 30 minutes. Perfect for using that one ripe banana, they’re loaded with melty chocolate and warm spices for the ultimate cozy treat.

Ingredients

Scale
  • 1 small overripe banana, mashed (about 1/4 cup)
  • 1/2 cup vegetable oil or melted butter
  • 1 cup light brown sugar, packed
  • 1 egg yolk
  • 1 teaspoon vanilla extract
  • 1 1/3 cups all-purpose flour
  • 1/2 teaspoon baking soda
  • 2 teaspoons ground cinnamon
  • 1/2 teaspoon salt
  • 2/3 cup chocolate chips

Instructions

  1. In a large bowl, mix the mashed banana, vegetable oil, and brown sugar until smooth.
  2. Add the egg yolk and vanilla extract, stirring to combine.
  3. Add the flour, baking soda, cinnamon, and salt. Stir just until no streaks of flour remain.
  4. Fold in the chocolate chips.
  5. Let the dough rest while the oven preheats to 350°F (about 15 minutes).
  6. Line a baking sheet with parchment paper. Scoop 1-inch dough balls and place them 2 inches apart on the sheet.
  7. Bake for 10–11 minutes, until edges are set but centers appear underbaked.
  8. Cool on the baking sheet for 5 minutes before transferring to a wire rack.

Notes

  • Use a very ripe banana for best flavor and sweetness.
  • Do not overmix the dough to avoid cakey texture.
  • Undercook slightly for a gooey center—cookies continue baking after removal.
  • To make vegan, replace egg yolk with 1½ tsp ground flaxseed + 2 tbsp water.
  • Store in an airtight container for up to 4 days.
