I first made these banana brownies on a rainy afternoon when the last two overripe bananas were staring at me from the fruit bowl. They turned into a moist, chocolatey tray of squares that feel indulgent but are actually made with pantry-friendly, whole-food ingredients — bananas, cocoa, oats — and no refined flour. They’re perfect for a lunchbox treat, an after-school snack, or a simple dessert when you want something a little healthier without sacrificing chocolate.

Why you’ll love this dish

This recipe delivers brownie satisfaction with fewer processed ingredients. It’s quick to mix, uses ripe bananas as natural sweetener and binder, and keeps well — so it’s great for batch baking. Parents love that kids usually approve, and bakers appreciate the forgiving technique (no creaming butter or tempering chocolate).

Quick: ready in about 30 minutes start to finish.
Budget-friendly: uses everyday pantry staples.
Flexible: easily made gluten-free or grain-free with almond flour.
Less sugar: maple syrup and bananas do most of the sweetening.

“I swapped my usual brownies for these and couldn’t tell they were lighter — gooey center, rich chocolate flavor, and my kids asked for seconds.” — a happy tester

Step-by-step overview

Mash ripe bananas into a smooth purée.
Whisk in eggs, maple syrup, yogurt, vanilla, and melted coconut oil.
Fold in dry ingredients (cocoa, oat flour, baking soda, salt, optional cinnamon) until just combined.
Pour batter into an 8×8-inch pan and bake at 180°C (350°F) for about 20 minutes.
Cool fully so the brownies set, then slice into nine pieces.

What you’ll need

2 ripe bananas — mashed (about 1 cup)
2 large eggs (see Variations for vegan swap)
1/4 cup maple syrup (or honey)
1/4 cup unsweetened Greek yogurt (or applesauce for dairy-free)
1 tsp vanilla extract
2 tbsp coconut oil, melted (sub: neutral oil like avocado)
1/3 cup unsweetened cocoa powder
1/2 cup oat flour (or almond flour for a grain-free option)
1/4 tsp baking soda
1/4 tsp sea salt
1/4 tsp cinnamon (optional, for warmth)

Notes: If using almond flour, the texture will be slightly denser and more tender. If your oat flour is homemade, measure by weight if possible (about 60 g for 1/2 cup) to avoid a gummy crumb.

Directions to follow

Preheat the oven to 180°C (350°F). Line an 8×8-inch (20×20 cm) baking pan with parchment paper, leaving an overhang to lift the brownies out.
In a medium bowl, mash the ripe bananas until smooth.
Add the eggs, maple syrup, Greek yogurt, vanilla, and melted coconut oil. Whisk until evenly combined.
Sift or add the cocoa powder, oat flour, baking soda, sea salt, and cinnamon (if using) to the wet mixture. Stir gently until just combined; avoid overmixing.
Pour the batter into the prepared pan and smooth the top with a spatula.
Bake for about 20 minutes. The edges should be set and a toothpick inserted into the center should come out with a few moist crumbs (not wet batter).
Cool completely in the pan on a wire rack — cooling fully helps the brownies firm up so you can slice neat squares.
Lift using the parchment overhang and slice into 9 brownies.

Chef’s note: The recipe calls for baking soda because the mashed banana provides acidity that reacts with it. If you change the egg to a vegan substitute, see the Variations section for leavening adjustments.

Best ways to enjoy it

Warm with a scoop of vanilla Greek yogurt or dairy-free ice cream.
Dust lightly with powdered sugar or cocoa for a pretty finish.
Serve with fresh berries and a drizzle of extra maple syrup for brunch.
Pack a brownie with a small portion of nuts for a portable snack that keeps hunger at bay.

How to store & freeze

Room temperature: Store in an airtight container for up to 2 days.
Refrigerator: Keep in an airtight container for 4–5 days; let them come to room temp or warm for 10–15 seconds in the microwave before serving.
Freezing: Wrap individual squares in plastic wrap and place in a freezer bag for up to 3 months. Thaw overnight in the fridge or at room temperature for an hour.
Food safety tip: Because this recipe contains eggs, don’t leave leftovers out longer than 2 hours at room temperature.

Extra advice

Banana ripeness matters: the riper the bananas (lots of brown speckles), the sweeter and more flavorful the brownies.
Oat flour consistency: If your oat flour is coarse, pulse it briefly in a food processor for a finer crumb.
Don’t overbake: these are meant to be moist. Start checking at 18 minutes to avoid dryness.
Add-ins: fold in 1/3 cup dark chocolate chips, chopped nuts, or a swirl of almond butter before baking for extra indulgence.
Reducing sweetener: you can reduce maple syrup to 3 tbsp, but the brownies will be less sweet and slightly denser.

Recipe variations

Chocolate chip swirl: Fold in 1/3 cup dark chocolate chips or drop spoonfuls of peanut butter into the batter and swirl before baking.
Vegan: Replace eggs with 2 flax eggs (2 tbsp ground flax + 6 tbsp water, mixed and rested 5–10 minutes). Add 1/2 tsp baking powder along with the baking soda to help with lift.
Grain-free: Use 1/2 cup almond flour instead of oat flour and reduce baking time by 1–2 minutes; watch closely.
Lower sugar: Swap maple syrup for 1/4 cup unsweetened applesauce and add a splash more vanilla; texture will be slightly softer.
Spiced cocoa: Add 1/8 tsp instant espresso powder and 1/4 tsp cinnamon for a deeper, mocha-like flavor.

Helpful answers

Q: Can I make these ahead for a party?
A: Yes. Bake, cool completely, and store in the fridge up to 4 days. Bring to room temperature or warm briefly before serving.

Q: Will these rise much?
A: These are meant to be dense and fudgy rather than cake-like. The small amount of baking soda gives a little lift, but don’t expect a high rise.

Q: Can I use all-purpose flour instead of oat flour?
A: Yes — use 1/2 cup all-purpose flour in place of oat flour for similar structure. If using regular flour, the brownies will be slightly firmer.

Q: Are they safe with eggs in them for kids?
A: Yes, provided the eggs are cooked in an oven at the recommended temperature. If serving to very young children, ensure proper storage and consume within a few days.
