Foolproof Method (bakery domes every time)

  1. Preheat oven to 220 °C (425 °F) — yes, really that hot.
    Line or grease a 12-cup muffin tin (paper liners OK, but naked greased cups give taller domes).
  2. In a large bowl, whisk very well (60 seconds):
    discard + milk + oil/butter + eggs + sugar + vanilla
  3. Add all dry ingredients at once:
    flour + baking powder + baking soda + salt
    Fold with a spatula exactly 12–15 strokes — still lumpy is perfect.
  4. Fold in your add-ins (see variations below).
  5. Divide batter — fill cups all the way to the top (even slightly mounded).
  6. Bake at 220 °C for 8 minutes → then, without opening the door, drop to 180 °C (355 °F) and bake another 10–14 minutes until deep golden and a toothpick has just a few moist crumbs.
  7. Cool in tin 5 minutes → remove to rack. Best eaten warm.

Top 5 Variations (use 150–200 g total add-ins)

Variation
Add-Ins
Extra Touch
Blueberry-Lemon

Double Chocolate
100 g chocolate chips + 30 g cocoa powder (reduce flour to 220 g)
Extra 80 g chips on top before baking
Banana-Nut
2 mashed very ripe bananas (≈220 g) + 100 g chopped walnuts
1 tsp cinnamon + brown sugar topping
Apple-Cinnamon
200 g diced apple + 2 tsp cinnamon + 50 g raisins
Turbinado sugar sprinkled on top
Morning Glory
80 g grated carrot + 80 g grated apple + 50 g coconut + 50 g pecans + 1 tsp cinnamon
Cream cheese frosting is optional

Pro Tips for Insane Domes & Moisture

  • High initial heat (220 °C) = tall muffin tops
  • Fill cups completely full (this batter doesn’t overflow)
  • Oil keeps them moist for 4–5 days (butter tastes better day 1)
  • Freeze beautifully — reheat 20 seconds in microwave or 5 min in 180 °C oven

These muffins are legitimately addictive — the sourdough discard gives a tender crumb and subtle tang that makes people say “what IS in these?!”
Make a double batch; they disappear fast.
