How It Works

How Muffin Batch Amounts Are Calculated

Batter per Muffin

  • Mini muffin: About 30 g (1 tablespoon) of batter per cup.
  • Standard muffin: About 75 g (3 tablespoons) of batter per cup, filling 2/3 full.
  • Jumbo muffin: About 150 g (6 tablespoons) of batter per cup.

    • Typical Batter Ratios

    A standard muffin batter is approximately:

  • 35% flour
  • 20% sugar
  • 15% fat (butter or oil)
  • 30% liquid + eggs

    • Worked Example

    Calculate batter for 12 standard muffins.

    num_muffins = 12muffin_size = 75
    1. 01Total batter = 12 x 75 = 900 g.
    2. 02Flour = 900 x 0.35 = 315 g.
    3. 03Sugar = 900 x 0.20 = 180 g.
    4. 04Butter/oil = 900 x 0.15 = 135 g.
    5. 05Batter volume = 900 / 240 = 3.8 cups.

    Frequently Asked Questions

    How full should I fill muffin cups?

    Fill standard muffin cups about 2/3 full for a nice dome. For muffin-top style (big tops), fill nearly full. Mini muffin cups should be 3/4 full.

    What causes flat muffins?

    Flat muffins are usually caused by expired leavening, over-mixing the batter (which deflates air bubbles), or too much liquid. Mix until just combined for the best rise.

    Can I freeze muffin batter?

    Yes. Scoop batter into muffin cups, freeze until solid, then transfer to a freezer bag. Bake from frozen, adding 5-10 minutes to the bake time.
