Banana Brownie Bites

These Banana Brownie Bites are an easy, comforting dessert that comes together fast in a mini muffin pan. They’re made with ripe banana, fudgy chocolate centers, and glossy melted chocolate chips.

We love having ripe bananas on hand because it means simple treats like these brownie bites are back on the table. Our Classic Rice Krispie Treats are another easy dessert that’s perfect for sharing.

Honestly, comforting sweets made with ripe fruit and simple ingredients are always my favorite.

Ingredients

Here’s what I use for this recipe and you can always make substitutions if you prefer.

• Cavendish banana: Use two very ripe bananas for mashing and one firm banana for twelve fresh serving rounds.
• Plain whole-milk Greek yogurt: Bring to about 70°F so it blends smoothly with the melted butter.
• Large egg: Bring to room temperature before whisking for a smoother emulsion.
• Light brown sugar: Pack firmly because its molasses keeps the brownie centers soft.
• Unsalted butter: Melt 2 tablespoons for the batter and soften 1 tablespoon for greasing the pan.
• Pure vanilla extract: Use pure extract to round out the cocoa and ripe banana aromas.
• All-purpose flour: Spoon into the cup and level it so the batter doesn’t become dry.
• Dutch-process cocoa powder: Sift before folding for a dark color and smooth chocolate flavor.
• Baking soda: Measure level because excess soda creates a soapy taste and tall cakey tops.
• Diamond Crystal kosher salt: Use a level measure to sharpen the chocolate without making the bites salty.
• Semi-sweet chocolate chips: Fold 1/2 cup into the batter and reserve 1/4 cup for the glossy tops.

Tools You’ll Need

• 24-well mini muffin pan: A dark metal 24-well mini muffin pan creates crisp edges and even portions, while oversized wells extend the bake and can leave gummy centers.
• Large clear glass mixing bowl: A 3-quart glass bowl gives enough room for broad folds and lets you spot dry cocoa pockets, while a narrow bowl encourages overmixing.
• Balloon whisk: A medium balloon whisk dissolves the sugar and combines the wet mixture, while a tiny whisk leaves banana lumps around the bowl.
• Rubber spatula: A flexible heat-safe spatula folds the batter without building excess gluten, while a rigid spoon can overwork the flour.
• Fine-mesh sieve: A 5-inch fine-mesh sieve breaks cocoa and flour clumps before folding, while a coarse strainer lets bitter dry pockets pass through.
• 1 1/2-tablespoon cookie scoop: A spring-loaded 1 1/2-tablespoon scoop portions all 24 wells evenly, while a larger scoop overfills the cups and causes stuck edges.
• Wire cooling rack: A sturdy wire rack releases steam beneath the bites after 10 minutes, while a flat plate traps moisture and softens the bottoms.

Instructions

Step 1: Mash the bananas and whisk the wet mixture

Bring the Greek yogurt and egg to about 70°F. Mash two very ripe Cavendish bananas against the bowl for 60 seconds, then whisk in the yogurt, egg, light brown sugar, 2 tablespoons melted unsalted butter and vanilla for another 60 seconds. Scrape the sides once halfway through so no thick streaks remain. Cold yogurt can make the butter firm into tiny lumps.

The mixture should look thick and glossy with small banana flecks. You’ll smell vanilla and ripe banana before the cocoa goes in. Stop when the sugar feels mostly dissolved between two fingers. A few tiny fruit specks are right and give the crumb character.

Whisking longer than 2 minutes adds excess air and makes the centers cakier. Room-temperature wet ingredients keep the fat evenly dispersed. Preheat the oven to 350°F now so it’s fully hot by the time the pan goes in.

Tip: Weigh the mashed banana at about 225 grams because extra fruit can make the centers gummy.

Step 2: Fold the cocoa batter

Sift all-purpose flour, Dutch-process cocoa, baking soda and Diamond Crystal kosher salt directly over the wet mixture at 70°F. Fold with a rubber spatula in broad J-shaped strokes for 45 to 60 seconds. Add 1/2 cup semi-sweet chocolate chips when only a few pale flour streaks remain, then fold 6 more times.

Scrape the bottom once so no dry cocoa pocket hides there. The batter should become very dark, thick and slightly shiny. It should fall from the spatula in a slow ribbon that holds for two seconds.

Stop as soon as dry streaks disappear. Go past 75 seconds and gluten tightens, which makes the bites rubbery instead of fudgy. Gentle folding limits gluten and preserves a dense center.

Tip: Sift the cocoa from 6 inches above the bowl so dry lumps break apart before they reach the wet mixture.

Step 3: Portion the batter into the mini muffin pan

Heat the oven to 350°F and brush all 24 mini muffin wells with the remaining 1 tablespoon softened unsalted butter for 1 minute. Divide 1 1/2 tablespoons of batter into each well over 3 to 4 minutes, filling every cup three-quarters full. Top the portions with the remaining 1/4 cup semi-sweet chocolate chips. (I filled my first batch to the rim, six overflowed and stuck.

Three-quarters full is the fix. ) Each well should hold a glossy dark mound with 2 to 3 chips visible. The portions won’t look identical and that’s good. Keep batter off the rims because baked sugar glues the bites to the pan.

Let the filled pan sit no longer than 5 minutes before baking or baking soda loses lift. Equal portions set at the same pace.

Tip: Use a 1 1/2-tablespoon cookie scoop and wipe its edge every 6 portions for cleaner wells and less wasted batter.

Step 4: Bake until the centers stay fudgy

Bake the filled mini muffin pan at 350°F for 12 to 14 minutes. Rotate the pan front to back at minute 7, then check at minute 12. A toothpick should show thick moist crumbs, not liquid batter.

Cool in the pan for 10 minutes, then loosen and transfer the bites to a wire rack for another 15 minutes. The tops will look matte around the edges while the semi-sweet chocolate chips stay glossy. The centers should spring back slowly and keep a slight dip.

Banana Brownie Bites turn dry after minute 15, so don’t wait for a clean toothpick. (I tried 375°F once, the edges set before the centers caught up. ) The 350°F bake keeps the banana sugars from scorching.

Tip: Check three bites from different pan zones because dark metal heats the outer wells about 1 minute faster.

Step 5: Plate the bites with fresh banana

Cut the firm Cavendish banana into twelve 1/4-inch rounds at about 70°F. Plate four brownie bites and place one banana round on two of them, then split one bite open. Finish within 5 minutes so the fruit looks fresh.

Press each banana round lightly so it sits against the soft top without flattening it. The plated bites should show irregular crinkled tops, glossy chocolate chips and a dense dark center. The banana rounds should look pale yellow with no gray edges.

Leave them out longer than 20 minutes and the fruit starts browning. Serve at room temperature for the fudgiest texture. Fresh slicing keeps the garnish bright and clean.

Tip: Set the two banana-topped bites behind the split piece so the dense center stays visible in every serving.

Pro Tips

• Use bananas with at least 70 percent brown spotting because pale yellow fruit won’t mash smoothly or provide enough sweetness.
• Measure flour by spooning and leveling 3/4 cup, since scooping directly can add 20 grams and dry the centers.
• Keep the oven at 350°F and check at minute 12 because mini wells move from fudgy to dry very quickly.
• Fill each well three-quarters full and leave the rims clean, which prevents baked sugar from gluing Banana Brownie Bites to the pan.
• Let the bites rest in the pan for exactly 10 minutes before loosening so their soft centers don’t collapse.
• Reserve 1/4 cup chocolate chips for the tops because visible glossy pieces give a stronger chocolate aroma and a more textured finish.
• Slice the serving banana no more than 5 minutes before plating so the rounds stay pale and don’t develop gray edges.

• Add 1/2 teaspoon ground cinnamon to the cocoa mixture for a warmer banana bread flavor.
• Fold in 1/3 cup finely chopped toasted walnuts and reduce the chocolate chips to 1/2 cup for a nutty crunch.
• Replace 1/4 cup chocolate chips with 1/4 cup peanut butter chips for a banana and peanut butter twist.
• Add 1 teaspoon instant espresso powder with the cocoa to deepen the chocolate without making the bites taste like coffee.

Storage Instructions

Store cooled Banana Brownie Bites without fresh banana garnish in a shallow airtight container for 4 days in the refrigerator. Place parchment between layers so the glossy chocolate tops don’t stick. For freezing, wrap pairs tightly and seal them in a freezer bag for up to 2 months.

Freeze the bites only after they’ve cooled for 25 minutes, since trapped steam forms icy patches. Reheat refrigerated bites at 300°F for 4 to 5 minutes or microwave one bite for 10 seconds. Thaw frozen portions for 30 minutes first, then warm them at 300°F for 5 to 6 minutes.

Add fresh banana rounds after reheating, never before. Discard bites with a sour smell, visible mold or a sticky wet surface that wasn’t present when stored.
