These banana peanut butter streusel muffins are soft, moist and combine a classic flavor combination in one delicious bite! These muffins are small batch (9 small cupcakes or 6 large muffins) and taste delicious even cold! Trust me when I say that these are an absolute crowd pleaser.

😋 Taste and features
- Soft yet still super moist
- Topped with a chunky peanut butter streusel
- Sweetened with bananas and brown sugar
- Small Batch – Only requires 2 bananas
- Goes perfectly with a dollop of jam!

🛒 Ingredient notes
- Oil: Oil keeps your muffins moist but still airy!
- Butter: Butter will be used for the streusel only.
- Sugar: A split between brown sugar and white sugar to get the perfect amount of sweetness!
- Egg: Just 1 egg to bind everything together!
- Flour: Nothing fancy, just all purpose flour for this recipe!
- Baking Powder: Baking powder will help give these muffins lift!
- Peanut Butter: I used creamy peanut butter but if you’re a chunky fan – go for it!
- Bananas: Make sure they’re nice and ripe to enhance sweetness.

👩🍳 Top tips
- Don’t over-mix your batter – you want to make sure the ingredients are just combined but if you mix too much you’ll end up with dense muffins!
- If you happen to be short one banana you can swap it out with apple sauce to make up for the difference.
- Use “regular” peanut butter as natural peanut butter tends to separate (peanuts from oil) and will affect your batter. For this recipe I used creamy “Skippy” peanut butter.
- Fill your batter 3/4 of the way into the pan so that it doesn’t overflow too much as you bake!

🧺 Storage tips
- Room Temperature: Store at room temperature wrapped in an an airtight container for up to 3 days.
- Fridge: Cool cookies completely and store them in an airtight container for up to 1 week.
