Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• 2 cups rolled oats
• 1/2 cup unsweetened cocoa powder
• 2 ripe bananas, mashed
• 2 large eggs
• 1/2 cup milk
• 1/4 cup honey or maple syrup
• 1 teaspoon baking powder
• 1 teaspoon vanilla extract
• 1/2 cup chopped walnuts
• 1/3 cup dark chocolate chips (optional)
• Pinch of salt

Optional add-ins:

• 1 teaspoon cinnamon
• 1 teaspoon espresso powder
• 2 tablespoons peanut butter swirl
• 1 tablespoon chia seeds

Directions

1. Preheat your oven to 350°F (175°C). Grease an 8-inch baking pan or line it with parchment paper.
2. Add the rolled oats to a blender or food processor. Blend until the oats resemble a coarse flour texture. This helps create a softer cake consistency.
3. In a large mixing bowl, mash the ripe bananas until smooth.
4. Add the eggs, milk, honey, and vanilla extract to the bananas. Whisk until fully combined and creamy.
5. Stir in the blended oats, cocoa powder, baking powder, and salt. Mix until a thick batter forms.
6. Fold in the chopped walnuts and chocolate chips if using.
7. Pour the batter into the prepared baking pan and spread evenly with a spatula.
8. Bake for 25 to 30 minutes, or until the center is just set. Avoid overbaking to keep the cake moist and fudgy.
9. Allow the cake to cool for at least 15 minutes before slicing. The texture becomes even richer as it cools.
10. Serve warm with coffee, milk, or fresh berries for an extra comforting treat.

Variations

• Replace bananas with unsweetened applesauce for a milder flavor.
• Swap walnuts for pecans or almonds for a different crunch.
• Use dairy-free milk such as almond or oat milk to make it dairy-free.
• Add shredded coconut for extra texture.
• Stir in dried fruit like raisins or chopped dates for natural sweetness.
• Top the cake with extra chocolate chips before baking for a richer finish.
• Make muffins instead of cake by dividing the batter into muffin cups and reducing the baking time to about 18–22 minutes.

Storage/Reheating

Store leftover cake in an airtight container in the refrigerator for up to 5 days. The cake tastes even fudgier after chilling overnight.

To freeze, wrap individual slices tightly and store in a freezer-safe container for up to 2 months. Thaw in the refrigerator before serving.

For reheating, microwave a slice for 10 to 15 seconds to restore the soft, gooey texture. You can also warm it in a low-temperature oven for a few minutes.
