Caramelized Banana Peanut Butter Muffins with Streusel
These peanut butter banana muffins combine the comfort of classic banana bread with the rich, nutty flavor of peanut butter at every layer. Ripe bananas are caramelized in brown butter to deepen their sweetness, then folded into a tender crumb enriched with Greek yogurt and creamy peanut butter. The magic happens in the toppings: a cinnamon-crunchy peanut streusel bakes right onto the muffin, while a silky peanut butter drizzle finishes each one. Perfect for breakfast lovers, snack enthusiasts, or anyone craving comfort food that tastes indulgent but still uses whole ingredients. Serve warm with coffee, pack for lunchboxes, or enjoy as an afternoon treat. What sets this version apart is the caramelized banana technique that concentrates flavor and the triple peanut butter approach—in the batter, streusel, and drizzle—creating depth that these beyond standard muffins.

Instructions
- 1
Preheat oven to 350 F.
- 2
Coat muffin pan with nonstick spray or line with muffin liners.
- 3
Heat butter and 2 bananas in a small pan over medium heat, stirring often, until bananas caramelize and butter browns, about 10 minutes. Set aside to cool.
- 4
Whisk together flour, baking soda, and salt in a medium bowl.
- 5
Using an electric mixer on medium-high speed, beat brown sugar, yogurt, peanut butter, and remaining butter in a large bowl until light and fluffy, about 4 minutes.
- 6
Add eggs one at a time, beating to blend after each addition and scraping bowl as needed.
- 7
Mix in vanilla and remaining 2 bananas until broken down to small chunks.
- 8
Reduce speed to low and fold in flour mixture.
- 9
Mix in caramelized brown butter bananas.
- 10
Spoon batter into prepared pan, filling each cup about 2/3 of the way.
- 11
Make streusel by combining chopped peanuts, flour, sugar, melted butter, and cinnamon in a medium bowl. Sprinkle 1 to 2 tablespoons over each muffin.
- 12
Transfer muffin tray to oven and bake until a toothpick inserted into the center comes out clean, 15 to 18 minutes. Remove from oven and let cool.
- 13
While muffins bake, combine peanut butter, maple syrup, and coconut oil in a microwave-safe bowl.
- 14
Microwave on high for 30 seconds, then stir. Repeat if needed until runny consistency is achieved.
- 15
Drizzle peanut butter mixture over cooled muffins and serve.
Tips
Caramelize the bananas slowly over medium heat and let them cool completely before folding into batter. This prevents them from breaking down further and losing the rich, concentrated flavor that defines these muffins.
Use very ripe bananas with brown spots for maximum sweetness and moisture. Overripe bananas create a more tender crumb and need less additional sugar.
Make the peanut butter drizzle just before serving. If it hardens as muffins cool, reheat briefly in the microwave to achieve the right pourable consistency.
Good to Know
Store in an airtight container at room temperature for up to 3 days, or refrigerate for up to 5 days. Freeze baked muffins for up to 3 months; thaw at room temperature.
Prepare dry ingredients the night before. Caramelize bananas and make streusel up to 4 hours ahead. Prepare batter no more than 30 minutes before baking to preserve leavening.
Serve warm with coffee, tea, or milk. Pair with butter, additional peanut butter, or a thick yogurt dollop. Excellent for breakfast, snacks, or lunchbox inclusions.
Common Mistakes
Do not overmix the batter after adding flour to avoid tough, dense muffins. Fold gently until just combined.
Do not skip cooling the caramelized bananas before folding into batter to prevent them from breaking down into a puree.
Do not underbake; use the toothpick test to ensure the crumb is fully set or muffins will collapse slightly as they cool.

FAQ
Can I make these muffins without Greek yogurt?
Yes, substitute sour cream at a 1:1 ratio for the same tanginess and moisture. Plain yogurt also works but may make the batter slightly thinner; reduce liquid elsewhere slightly if needed.
What if I don't have roasted unsalted peanuts for the streusel?
Chopped walnuts, pecans, or almonds work well, though they shift the flavor profile slightly. You can also omit nuts entirely and increase the flour by 2 tablespoons to maintain the streusel texture.
How long do these muffins keep and can I freeze them?
Store at room temperature for 3 days or refrigerate for 5 days in an airtight container. Freeze baked muffins for up to 3 months; thaw at room temperature. Freeze without the drizzle for best texture, then drizzle after thawing.
