Moist banana brownies
These banana brownies fuse two of my favorite desserts — traditional chocolate brownies and sweet banana bread. They’re the perfect way to use up ripe, spotty bananas you have lying around!
Plus, adding mashed bananas gives the brownies a naturally sweet flavor without using too much sugar. I also like to add a pinch of instant coffee to enhance the chocolate flavor even further (trust me, it makes a world of difference)!
I’ve kept the recipe vegan-friendly by using soy milk, coconut oil, and vegan chocolate chips, ensuring that almost everyone can indulge. After a quick bake, these brownies turn out moist, fudgy, and irresistibly delicious.
Ingredients & Substitutions

- All-purpose flour: Gives structure to the brownies while maintaining a tender crumb. Substitute all-purpose flour with a gluten-free blend if you’re sensitive to gluten.
- Cocoa powder: I recommend Dutch-processed cocoa powder for a rich, deep chocolate taste. If you don’t have Dutch-processed cocoa, use natural cocoa powder instead.
- Sugar: In addition to the bananas, granulated sugar adds sweetness. Try coconut sugar for a healthier, less processed alternative.
- Baking powder: Helps the brownies rise. Ensure it's fresh for the best results.
- Instant coffee: Enhances the chocolate flavor. You can omit the instant coffee if you don’t have any or replace it with espresso.
- Banana: Brings natural sweetness and moisture. It also helps bind the brownies in place of eggs. Overripe (very spotty) bananas work best here.
- Soy milk: Adds extra moisture to the batter. Oat or cashew milk are great substitutes.
- Vinegar: I prefer white vinegar for baking, but you can use apple cider vinegar or lemon juice if you prefer.
- Coconut oil: Gives the brownies a rich flavor and texture. Vegan butter also works.
- Vanilla: Enhances the sweetness of the brownies. Make sure it’s pure vanilla extract.
- Vegan chocolate chips: For bursts of melty chocolate flavors in each bite. Any vegan-friendly chips or chopped chocolate will work.
How to make chocolate banana brownies

- Step 1: Preheat your oven to 350F and line an 8x8” baking pan with parchment paper. This makes the removal process easier and ensures clean slicing of the brownies.

- Step 2: Mix soy milk with vinegar in a bowl to form a dairy-free buttermilk. This adds a subtle tang and creates a tender crumb.

- Step 3: Sift together the flour, cocoa powder, and baking powder, then stir in the sugar and instant coffee. Sifting prevents lumps for a smoother batter, so don’t skip this step.


- Step 4: Whisk together the mashed banana, coconut oil, vanilla, and soy buttermilk. Fold the dry mix into the wet, then add your chocolate chips.


- Step 5: Add a few chocolate chips on top, then bake these chocolate banana brownies for 40 minutes. Let them cool for 20 minutes before lifting them out to slice into squares.
Storage & Reheating
If you’re preparing your banana brownies in advance or have leftovers, here’s what to do:
- Room temperature: You can keep the slices in an airtight container on the counter for up to 4-5 days. I like to place pieces of parchment paper between the brownies to prevent sticking, especially if they’re stacked.
- Freezer: For longer storage, transfer the brownies to the freezer for up to 3 months. Wrap individual pieces in parchment paper or cling wrap, then store them in a freezer bag.
Variations
- Nutty banana brownies: Add chopped walnuts or pecans for a crunchy texture.
- Spice: Mix in cinnamon or nutmeg for a warm, spiced flavor.
- Fruit: Top the brownies with banana slices or raspberries before baking.
- Protein-packed: Replace some flour with a scoop of chocolate vegan protein powder.
- Salted caramel: Drizzle the tops with vegan caramel sauce and a pinch of sea salt before serving.

Top tips
- Ripe bananas: Use overripe bananas for the optimal sweetness and texture.
- Don't overmix: Mix just until combined to avoid tough brownies.
- Properly line the pan: Ensure the parchment paper overhangs the pan for easy removal and clean cuts.
- Check doneness: You’ll know the brownies are done when a toothpick comes out with a few moist crumbs attached.
- Even slicing: Use a sharp knife and clean it between cuts for neat squares. Wash it with hot water between slices and dry it with a cloth for the best results.
- Ingredient temperature: Use room temperature ingredients for even mixing.
FAQ
Dryness in brownies usually results from overbaking them or using excessive flour, which absorbs moisture. To avoid this, measure your flour precisely and keep a close eye on the baking time, checking for doneness towards the end.
Perfectly baked brownies will have a fudgy, moist texture, so they should be slightly underbaked in the center when they come out of the oven. To test them, insert a toothpick into the center of the brownies. It should come out with a few crumbs clinging to it, not completely clean or with wet batter.
The key to getting brownies to rise properly is using fresh baking powder, as it loses its effectiveness over time. Also, ensure that you measure it accurately, as too little won't provide enough lift, and too much can cause them to rise and then collapse.
