Banana Peanut Butter Blueberry Muffins (No Flour, No Sugar)
Soft, naturally sweet muffins made with just four simple ingredients. These muffins are moist, fluffy, and incredibly easy to make. They contain no flour and no added sugar — the sweetness comes entirely from ripe bananas and juicy blueberries.
- 2 ripe bananas the riper, the sweeter—spotty skins are ideal
- 2 large eggs
- 1 tablespoon peanut butter smooth or crunchy; unsweetened is great
- 1 cup blueberries fresh or frozen
Optional (highly recommended for extra flavor, but not required):
- Pinch of salt makes everything taste more “banana-bready”
- 1/2 teaspoon vanilla rounds out the flavor
- 1/2 teaspoon cinnamon warm, dessert-like
- 1 teaspoon lemon zest brightens blueberries
Preheat your oven to 180°C (350°F).
Line an 8×8 inch baking pan with parchment paper, leaving some overhang to easily lift the bake out later.
Place the peeled bananas into a mixing bowl. Mash thoroughly with a fork until mostly smooth.
Add the eggs and peanut butter to the mashed bananas.
If using optional ingredients like vanilla, cinnamon, or salt, add them now.
Add the Blueberries
Divide the batter evenly between the muffin cups, filling each about ¾ full.Add a few extra blueberries on top of each muffin for a beautiful bakery-style finish. bake for about 25 minutes.
Allow the bake to cool in the pan for 15–20 minutes.
