Ingredients Needed
- 2 ripe bananas, mashed
- ½ cup plain Greek yogurt
- ⅓ cup natural peanut butter
- ¼ cup honey or maple syrup
- 1 large egg
- 1 teaspoon vanilla extract
- 1 ½ cups oat flour (or all-purpose)
- ½ teaspoon baking soda
- ¼ teaspoon salt
- ½ cup chocolate chips
- ¼ cup chopped walnuts (optional)
Ingredient Notes
The riper your bananas, the sweeter and gooier these blondies turn out, so reach for the spotty ones. Full-fat Greek yogurt keeps the crumb moist and rich. Use runny natural peanut butter for an easy-folding batter. I love oat flour for a soft, tender bite, but all-purpose gives a sturdier blondie.
How to Make It
Step 1: Preheat and Prep
Preheat your oven to 350°F. Then line an 8×8 inch pan with parchment, leaving overhang on two sides for easy lifting.
Step 2: Mash and Whisk
Mash the bananas in a large bowl, then whisk in the Greek yogurt, peanut butter, honey, egg, and vanilla until smooth.
Step 3: Add the Dry
Stir in the oat flour, baking soda, and salt. Fold gently until just combined, since overmixing turns blondies dense and tough.
Step 4: Fold In the Mix-Ins
Fold in most of the chocolate chips and the walnuts. Then spread the thick batter firmly and evenly into the pan.
Step 5: Bake Until Just Set
Scatter the remaining chips on top, then bake for 22 to 26 minutes until the edges set. Pull them early for gooey centers.
Pro tip: Let them cool 15 minutes before slicing so the gooey centers firm up just enough to hold.
Key Ingredients & Health Benefits
Banana is the quiet hero here, sweetening and binding at once. It replaces refined sugar, adds natural moisture, and delivers potassium and fiber that make these blondies genuinely energizing.
Greek yogurt swaps in for butter completely, adding a subtle tang and a tender crumb. It also brings calcium, probiotics, and a real protein boost that keeps these blondies satisfying.
Natural peanut butter adds that rich, nutty depth everyone craves. Beyond flavor, it contributes plant-based protein and heart-healthy fats that keep hunger away for hours after one square.
Oat flour gives each blondie a soft, tender texture and slow-digesting fiber. It steadies blood sugar and keeps you fuller far better than refined white flour ever could.
Customization Ideas
These healthy peanut butter chocolate banana bread blondies are wonderfully easy to make your own.
- Swap almond butter for peanut butter to lighten the flavor and let the banana shine.
- Use dark chocolate chips at 70% cacao for a richer, more grown-up bite.
- Skip the walnuts and add pecans or chopped peanuts for a different crunch.
- Add ½ teaspoon cinnamon for a cozy, banana-bread warmth throughout.
- Sprinkle flaky sea salt on top to amplify that sweet-salty contrast.
Pro Tips & Common Mistakes
Use truly ripe bananas, not just yellow. Trust me, under-ripe bananas leave these blondies bland and dry. The browner and spottier, the sweeter and gooier your results.
Don’t overmix once the flour goes in. Stir just until combined, since heavy mixing builds too much gluten and bakes up tough instead of tender.
Finally, pull the pan early rather than late. These blondies keep cooking from residual heat, so a barely-set center keeps that gooey middle. Overbake and they dry out.
Storing & Freezing Guide
Store these blondies in an airtight container at room temperature for 2 days, or in the fridge for up to 6 days, where they stay soft and gooey. For longer storage, wrap individual squares in parchment and freeze in a zip-lock bag for up to 2 months. Thaw at room temperature, or microwave one for 10 seconds to bring back that melty center.
FAQs
Can I make these without an egg? Yes. Replace the egg with a flax egg: 1 tablespoon ground flaxseed whisked with 3 tablespoons water, rested 5 minutes until gel-like. The blondies turn slightly denser but still bake up nicely.
Can I use regular flour instead of oat flour? Absolutely. All-purpose flour creates a sturdier, more classic blondie, while oat flour keeps them softer and gluten-free. Both work beautifully, though the crumb shifts slightly.
Why did my blondies turn out dry? Most likely you overbaked them or used under-ripe bananas. Pull the pan when the center still looks barely set, and reach for the spottiest bananas next time.
Are these actually healthy? They skip butter and refined sugar, leaning on banana, yogurt, and peanut butter for protein and fiber. They’re a genuinely nourishing treat, not dessert in disguise.
