These Sourdough Discard Mini Muffins are quick, easy, and so fun to make. Customize them with your favorite mix-ins for a sweet breakfast or snack that everyone will love.
In a large bowl, whisk the melted butter and sugar until slightly glossy. Add the eggs one at a time, whisking well after each. Stir in the milk, sourdough discard, and vanilla until smooth.
½ cup (113 grams; 1 stick) unsalted butter, ¾ cup (150 grams) granulated sugar, 2 large eggs, ¾ cup (180 grams) whole milk, ½ cup (100 grams) sourdough starter discard, 1 teaspoon vanilla extract
Add the dry ingredients to the wet and gently fold with a spatula until just combined. Avoid overmixing. Fold in your mix-ins, such as mini chocolate chips, rainbow sprinkles, or freeze-dried blueberries.
½ cup mix-ins
Spoon the batter into the muffin cups, filling each about ¾ full. You’ll make about 48 mini muffins, so you may need to bake in two batches. Bake for 12–14 minutes, or until golden and a toothpick inserted in the center comes out clean.
Let the muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
