Cake to Cupcake Converter

Pick the cake your recipe makes and the cupcake size you want: get how many cupcakes, how long to bake them and how much frosting to make. Or go the other way and find the cake pan a cupcake recipe will fill.

How Many Cupcakes a Cake Recipe Makes

A standard cupcake takes about ¼ cup of batter (3 to 4 tablespoons), filling the liner two-thirds to three-quarters full. A recipe for two 9-inch layers makes about 6 cups of batter, which is where the familiar "24 cupcakes" comes from. Mini cupcakes take about a third as much batter each, and jumbo cupcakes about twice as much.

Counts and cake times are drawn from King Arthur Baking's and Handle the Heat's conversion guides. Recipes differ, so if an exact number matters — a party order, a school event — measure the batter in cups and use the "I measured the batter" option above.

Bake Time and Temperature

Bake cupcakes at the same temperature the cake recipe uses, usually 350°F. Only the time changes:

  • Standard cupcakes: 18–22 minutes.
  • Mini cupcakes: 9–12 minutes.
  • Jumbo cupcakes: 20–25 minutes.

Start checking at the low end. Cupcakes are done when a toothpick in the center comes out clean or with a few dry crumbs, or at an internal temperature of 205–210°F. For flatter tops that are easier to frost, bake at 325°F and add a few minutes; for taller domes, King Arthur suggests raising the oven 25°F.

How Full to Fill the Liners

Fill standard liners two-thirds to three-quarters full. A #16 portion scoop (¼ cup) gives one standard cupcake in a single scoop, which keeps them even so they finish baking together — see portion scoop sizes for the other numbers. Overfilled liners spill and bake into mushroom tops; underfilled ones stay below the rim and look sparse once frosted.

How Much Frosting You Need

King Arthur's figures for standard cupcakes are 2 to 2½ tablespoons each for a spread top and 3 to 4 tablespoons for a tall piped swirl. That makes 24 standard cupcakes need about 3½ cups of frosting spread on, or about 5 to 6 cups piped. A frosting recipe sized for a two-layer cake (about 3 to 4 cups) is enough for 24 cupcakes spread thinly but not piped; make one and a half to two batches for piping. Mini cupcakes take roughly a third as much each, and jumbo cupcakes about twice as much.

Cakes That Don't Convert Well

  • Pound cake: too dense; the cupcakes come out heavy.
  • Sponge and chiffon cakes: short and dry in small portions unless brushed with syrup.
  • Angel food cake: needs an ungreased tube pan to climb.
  • Flourless chocolate cake: no flour structure to stand up on its own.

Ordinary butter and oil cakes — yellow, white, chocolate, carrot, red velvet, box mixes — convert without changing the recipe at all.

Going the Other Way: Cupcakes to a Cake

Work out the batter first: 12 standard cupcakes is about 3 cups, which fills one 9-inch round or 8-inch square; 24 standard cupcakes is about 6 cups, enough for two 9-inch rounds, a 9×13 or a 10-inch Bundt. Use the cake's normal bake time from the table above at the same temperature. For any other pan, the baking pan size converter works out the scaling factor from pan volumes.

Muffins and quick breads follow the same logic with different times — see banana bread to muffins — and drop cookies can become a pan of bars: turning cookie dough into bars.

Frequently Asked Questions

How many cupcakes does a 2-layer cake recipe make?

About 24 standard cupcakes from a recipe for two 9-inch layers, filling each liner about two-thirds to three-quarters full. The same batter makes roughly 60–72 mini cupcakes or 12 jumbo cupcakes.

How long do you bake cupcakes from a cake recipe?

Keep the recipe's oven temperature and bake standard cupcakes about 18–22 minutes, mini cupcakes 9–12 minutes and jumbo cupcakes about 20–25 minutes. They are done at an internal temperature of 205–210°F or when a toothpick comes out clean.

How many cupcakes does a 9x13 cake recipe make?

About 24 to 30 standard cupcakes, depending on how full you fill the liners. 9×13 recipes vary more than layer cake recipes, so measure the batter if you need an exact count: each standard cupcake takes about ¼ cup.

Which cakes don't work as cupcakes?

Pound cake bakes up dense and heavy, sponge cake turns out short and dry, angel food cake needs its ungreased tube pan to climb, and flourless chocolate cake lacks the structure to stand on its own.
