These Strawberry Muffins are soft and very moist. They are loaded with strawberries and buttery streusel topping. They are simple to make and perfect for breakfast or a snack.
Preheat oven to 375°F (190°C). Line a standard 12-hole muffin tray with muffin liners. Set aside.
How to Make Streusel Topping
In the small mixing bowl, add flour, sugar, salt, and lemon zest. Mix until all is combined.
Add melted butter and stir until the mixture is crumbly and moist. Set aside.
How to Make Strawberry Muffins
In the large mixing bowl, combine sugar, egg, melted butter, oil, and milk. Using a whisk, mix until well combined.
Sift in dry ingredients: flour, baking powder, and salt to the wet ingredients. Using a spatula, gently fold until just combined.
Wash and cut fresh strawberries into cubes. Add strawberries, lemon zest, and lemon juice to the muffin batter. Using a spatula, gently fold until all is combined. Do not overmix. Overmixing will make the muffins dense instead of soft.
Distribute the batter evenly among the muffin liners, filling about 3/4 full. Using fingers, gently break the streusel and evenly sprinkle the tops of the muffins. You can also add more cubes of strawberries with the streusel.
Bake muffins for 18-22 minutes at 375°F (190°C) or until a toothpick inserted into the center comes out clear.
Let the muffins cool in the tray for a few minutes, then transfer them to a wire rack to cool completely.
Notes
Do not use frozen strawberries. Fresh always tastes better.
Overmixing the batter will make the muffins dense instead of soft.
Cut strawberries into small cubes instead of slices.
You can make mini muffins if you like. Baking time will be shorter.
