Instructions
Melt Butter: Melt butter and let cool slightly. Whisk together melted butter and sugar until smooth.
Add Wet Ingredients: Mix in sour cream, lemon juice, lemon zest, and sourdough discard. Add eggs one at a time, mixing just until combined.
Mix Dry Ingredients: In a separate bowl, whisk together flour and salt. If baking the same day, whisk in baking powder. (If long fermenting, omit baking powder until baking day.)
Combine: Gently fold dry ingredients into wet ingredients just until no dry streaks remain. Cover bowl.
Long Fermentation Option: Refrigerate covered batter overnight. Before baking, let the batter sit at room temperature 20–30 minutes.
Preheat Oven: Preheat oven to 425°F and let it fully heat for 20 minutes.
Add Baking Powder & Berries: If omitted due to long fermenting in the fridge, sprinkle baking powder over batter and fold in gently. Toss raspberries with 2 tablespoons flour, then carefully fold into batter.
Prepare Streusel: Mix flour and sugar. Cut in cold butter until crumbly. Stir in lemon zest if using.
Fill & Top: Line muffin tin and fill liners 3/4 full. Top each with 1–2 tablespoons streusel.
Bake: Bake at 425°F for 8 minutes. Reduce temp: After 8 minutes, without opening the oven, reduce temperature to 350°F and bake 18–22 minutes more.
Cool: Muffins are done when a toothpick inserted in the center comes out clean. Cool completely in pan before removing.
Notes
Storage & Freezing
Counter: 1–3 days in an airtight container Refrigerator: Up to 5 days Freezer (baked muffins or unbaked batter): Up to 3 monthsTo freeze baked muffins, allow them to cool completely. Wrap individually or store in an air-tight container.
Freezer Batter Hack (My Favorite Meal Prep Tip)
This is one of my favorite make-ahead tricks.After mixing the batter, transfer it into a gallon-sized zip-top bag. Freeze flat.When ready to bake:
Thaw overnight in the refrigerator
Snip the corner
Pipe into muffin liners
Bake as directed
This method makes fresh baked lemon raspberry sourdough muffins possible even on busy mornings. I prefer this method over freezing individually to save space and maintain that fresh from the bakery style muffin.
