Ingredients List
- 2 ripe bananas (mashed)
- 1/3 cup peanut butter
- 1/3 cup Greek yogurt

- 1 cup oat flour

Directions
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper for easy removal and cleanup.
Step 2: Combine Wet Ingredients
In a large mixing bowl, mash the ripe bananas until smooth. Add in the peanut butter, Greek yogurt, honey or maple syrup, egg, and vanilla extract. Stir or whisk until fully combined and creamy.
Step 3: Add Dry Ingredients
Add oat flour, baking powder, cinnamon, and a pinch of salt to the wet mixture. Stir until just combined—avoid overmixing, which can make the bars dense.
Step 4: Bake
Pour the batter into the prepared pan and spread it evenly. Smooth the top using a spatula.
Bake for 20–24 minutes, or until the top is golden and a toothpick inserted into the center comes out clean.
Step 5: Cool and Slice
Let the bars cool completely in the pan. Once cool, lift out the parchment and slice into squares or rectangles. Enjoy immediately or store for later.
