# What You Need:
→ Muffins
01 - 2 cups all-purpose flour
02 - 1 teaspoon baking powder
03 - 1/2 teaspoon baking soda
04 - 1/2 teaspoon salt
05 - 1/2 cup granulated sugar
06 - 1 cup sourdough starter, unfed or discard
07 - 1/3 cup vegetable oil or melted unsalted butter
08 - 2 large eggs
09 - 1/2 cup whole milk
10 - 1 teaspoon vanilla extract
11 - 1 1/4 cups fresh strawberries, diced
→ Crumb Topping
12 - 1/2 cup all-purpose flour
13 - 1/3 cup packed light brown sugar
14 - 1/4 cup unsalted butter, cold and diced
15 - 1/2 teaspoon ground cinnamon
16 - Pinch of salt
# How to Make:
01 - Preheat oven to 375°F. Line a 12-cup muffin tin with paper liners or grease thoroughly.
02 - In a medium bowl, whisk together flour, baking powder, baking soda, salt, and sugar until evenly distributed.
03 - In a separate bowl, whisk together sourdough starter, oil or melted butter, eggs, milk, and vanilla extract until smooth and fully incorporated.
04 - Pour wet ingredients into the dry mixture and stir gently until just combined. Do not overmix; lumpy batter is acceptable.
05 - Gently fold diced strawberries into the batter using a spatula, preserving fruit integrity.
06 - Divide batter evenly among muffin cups, filling each approximately three-quarters full.
07 - In a small bowl, combine flour, brown sugar, cinnamon, and salt. Cut in cold butter using a fork or fingertips until mixture resembles coarse breadcrumbs.
08 - Distribute crumb topping generously over each filled muffin cup.
09 - Bake for 22 to 25 minutes, until a toothpick inserted into the center emerges clean with no wet batter.
10 - Allow muffins to cool in the pan for 5 minutes, then turn out onto a wire rack for complete cooling.
