Peanut Butter Banana Muffins

Ingredients

• 1 cup all-purpose flour
• 0.75 cup quick cooking oats
• 1/3 cup packed brown sugar
• 1 tablespoon baking powder
• 1 cup milk
• 0.5 cup peanut butter
• 0.5 cup mashed ripe banana
• 1 large egg, beaten
• 2 tablespoons vegetable oil
• 1 teaspoon vanilla extract
• 0.25 cup all-purpose flour
• 2 tablespoons butter, melted
• 2 tablespoons packed brown sugar

Steps

1. Preheat the oven to 375 degrees F (190 degrees C). Grease 12 muffin cups or line with paper muffin liners.
2. Prepare muffins: Combine flour, oats, brown sugar, and baking powder in a bowl. Whisk together milk, peanut butter, banana, egg, oil, and vanilla in a separate bowl. Add banana mixture to dry ingredients, mixing just until moistened. Fill prepared muffin cups 3/4 full.
3. Make crumb topping: Stir together flour, melted butter, and brown sugar. Sprinkle topping evenly over muffins.
4. Bake in preheated oven until golden brown and a toothpick inserted into the center comes out clean, about 18 minutes. Serve warm.
