Instructions
Prep the oven & pan: Preheat oven to 425°F (220°C). Line a 12-cup muffin tin with parchment liners or grease well.
Mix the dry ingredients: In a medium bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, and nutmeg.
Make the batter: In a large bowl, whisk brown sugar, granulated sugar, oil, eggs, vanilla, sourdough discard, and milk until smooth. Gently fold in the dry ingredients until just combined, then fold in chopped apples.
Fill & bake: Divide batter evenly into muffin cups, filling almost to the top for a tall rise. Sprinkle with cinnamon sugar if using. Bake at 425°F for 5 minutes, then reduce oven temperature to 350°F (175°C) and bake an additional 15–18 minutes, until a toothpick comes out clean.
Cool & serve: Let muffins cool in the pan for 5 minutes before transferring to a wire rack. Best enjoyed warm!
Notes
I bake by weight for accuracy. Cup measurements are approximate and may vary depending on how you scoop.Audrey’s Tip: The initial 5 minutes at 425°F is what gives you those bakery-style domes! Don’t skip it. For extra crunch, sprinkle coarse sugar or cinnamon sugar generously before bakingNote: I chopped my apples a bit larger for more texture in the muffins, but if you prefer a more uniform muffin, finely dice or shred the apples before mixing them into the batter.
Storage
Let muffins cool completely before storing. Keep in an airtight container at room temperature for up to 3 days, or refrigerate for up to 5 days. Streusel will soften quickly when stored.To freeze, wrap tightly in plastic wrap or store in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator or reheat in the microwave for 20–30 seconds
