These flourless bars combine ripe bananas and creamy peanut butter for a naturally moist, rich texture. Ready in 32 minutes with just 10 minutes of prep, they're perfect for busy mornings or quick snacking.

The simple batter comes together in one bowl—no flour needed. Mashed bananas provide natural sweetness and structure while peanut butter adds protein and creamy richness. Dark chocolate chips offer optional decadence.

Bake until set, cool completely, then slice into eight satisfying bars. They're naturally gluten-free and can be made vegan with flax eggs. Store at room temperature for up to three days.

Last Tuesday my kitchen smelled like warm bananas and peanut butter at 9 PM because I forgot planned dessert until guests were already on their way. These bars saved me completely and now everyone asks for them whenever they come over. The whole house feels cozy when they are baking.

My sister grabbed three before I could even set the platter down at our family gathering last month. Now she texts me weekly asking if I have any stocked in the freezer for emergencies.

Ingredients

  • 2 large ripe bananas mashed: The browner and splotchier the better since they bring natural sweetness and moisture
  • 1 cup creamy peanut butter: Room temperature spreads easier and incorporates faster into the batter
  • 2 large eggs: These bind everything together without any flour needed
  • 1/4 cup pure maple syrup: Honey works too but maple adds a subtle depth that complements the bananas
  • 1 tsp vanilla extract: Pure extract makes a noticeable difference over imitation
  • 1/2 tsp ground cinnamon: Rounds out the sweetness and adds warmth
  • 1/4 tsp fine sea salt: Balances the rich peanut butter and brings out flavors
  • 1/2 tsp baking soda: Essential for lift since there is no flour or powder
  • 1/3 cup dark chocolate chips optional: Honestly make them mandatory for the best version

Instructions

Preheat your oven to 350°F and line an 8x8 pan:
Parchment paper prevents sticking completely and makes cleanup a breeze
Mash those bananas until smooth:
Use a fork or potato masher leaving only tiny chunks for texture
Combine all wet ingredients in one bowl:
Whisk until the mixture looks glossy and no peanut butter streaks remain
Add your dry spices and leavening:
Stir thoroughly to distribute the baking soda evenly throughout
Fold in the chocolate chips gently:
Do not overmix since you want pockets of melted chocolate in every bite
Spread batter evenly in your prepared pan:
The batter will be thick so use the back of a spoon to smooth it out
Bake for 20-22 minutes:
The center should feel set and a toothpick should come out mostly clean
Cool completely before slicing:
This step feels impossible but the bars firm up and cut perfectly when patient

My neighbor started leaving extra ripe bananas on my doorstep after she tried one at our block party. It became our little unspoken arrangement that I love.

Making These Vegan

Flax eggs work surprisingly well here without altering the taste or texture noticeably. Just mix ground flaxseed with water and let it sit for five minutes before adding.

Storage Secrets

Room temperature storage works for three days but the refrigerator extends that to a full week. The fridge also makes them firmer and somehow even more satisfying.

Serving Ideas

Warm these slightly in the microwave for fifteen seconds before serving. The chocolate gets melty again and the peanut butter flavor pops.

  • Sprinkle flaky sea salt on top before baking for a professional touch
  • Serve with coffee for the ultimate afternoon pick me up
  • Crumble over vanilla ice cream for an incredible dessert

Simple ingredients coming together to create something that feels like a hug. That is the magic of these bars.

Recipe FAQs

Insert a toothpick into the center—if it comes out clean or with just a few moist crumbs, they're ready. The edges should be lightly golden and the center set but still soft to the touch.

Absolutely. Natural peanut butter works perfectly, though the bars may have a slightly oilier texture. Stir the peanut butter well before measuring to incorporate any separated oils.

Use large ripe bananas with plenty of brown spots—they're sweeter and mash more easily. Overripe bananas work exceptionally well, adding natural moisture and intense banana flavor.

Yes, the chocolate chips are optional. The bars taste delicious on their own, or you can add chopped peanuts, a swirl of jelly, or keep them plain for a classic banana peanut butter combination.

Store cooled bars in an airtight container at room temperature for up to three days. For longer storage, refrigerate for up to a week or freeze individually wrapped for up to three months.

Yes, you can swap peanut butter for almond butter or sunflower butter if avoiding peanuts. The texture remains similar, though the flavor profile will change accordingly.
