How to Make the Best Banana Brownies
Create the fudgiest brownies infused with real chocolate and bananas in just 3 simple steps! Follow the printable instructions in the recipe card at the end of the post.
- Mix the wet ingredients. Combine the melted chocolate and oil, then mix in the sugar, egg, and mashed banana.
- Add the dry ingredients. Gradually stir in the flour, cocoa powder, and salt. Fold in any mix-ins, like chocolate chips, at this point.
- Bake. Pour the batter into a lined 8″ baking pan and bake at 350ºF for 22-25 minutes. Cool, slice, and enjoy!
What Makes Brownies Have a Flaky Top?
The key to achieving brownies with glossy tops is thorough mixing of the eggs. Ensure the eggs are at room temperature and blend them well with the sugar and wet ingredients. This step is crucial in creating the thin, crackly crust on these brownies, along with the melted chocolate in the recipe.

Recipe Tips & Variations
- Use unsweetened chocolate. This allows better control over the sweetness of the brownies. If using sweetened chocolate, consider reducing the added sugar.
- Avoid overmixing. Once the dry ingredients are added, be careful not to overmix the batter to prevent dense, tough brownies.
- Don’t overbake. Brownies should be slightly moist in the center when done. Avoid baking too long to prevent dryness.
- Experiment with mix-ins. Try adding walnuts, pecans, almonds, or other fun options like chocolate bars or candies for extra flavor.
