Strawberry Banana Muffins with Crumb Topping are a really great way to use strawberries this season. This is like banana bread meets coffee cake, filled with juicy pieces of strawberries and topped with a sweet crumb topping. It'll be your new go-to muffin!
Preheat oven to 375F. Grease a muffin tin and set aside.
In a medium bowl whisk together dry ingredients (flour, spices, baking powder and soda, sugars). In a separate bowl, combine wet ingredients (banana, strawberries, oil, egg, vanilla).
Pour dry ingredients into wet ingredients and stir until combined. Be careful not to over-mix.
Use the now-empty dry ingredients bowl to combine sugar, flour, cinnamon, and butter for the crumb topping. Stir together until flour is completely wet and crumbling. Sprinkle evenly over each muffin.
Spoon batter into 10 muffin cups evenly. Bake about 15 minutes, or until golden brown and a toothpick comes out clean.
