- 1 cup oats
- 1 cup ground flax seeds
- 2 very ripe bananas, mashed
- 2 eggs
- 1/4 cup vegetable oil
- 2 teaspoons vanilla extract
- 1 cup white sugar
- Preheat oven to 350 degrees F (175 degrees C).
- Sift all-purpose flour, whole wheat flour, and cocoa powder together in a large bowl. Stir in oats and ground flax seeds.
- Beat bananas, eggs, vegetable oil, and vanilla extract together in a large bowl with an electric mixer until well-blended. Beat in sugar. Mix in flour mixture until dough is sticky.
- Roll a teaspoonful of dough into a ball with your hands and place on a nonstick baking sheet. Repeat with remaining dough.
