Recipe Scale Calculator
Scale any baking recipe by multiplier, tin size, or serving count. The only calculator that knows baking powder doesn't scale linearly — with smart leavening adjustments and egg rounding.
You just scaled 1 recipe manually. In BakeOnyx, your entire recipe library scales in one click — and costs update automatically with the new quantities. Try it free →
Leavening Agents (Baking Powder, Soda, Yeast)
Above 2×, leavening should be reduced to ~75% of the calculated amount. Too much leavening causes cakes to rise too fast then collapse. This calculator adjusts automatically.
Eggs
You can't use 2.5 eggs. This calculator shows gram equivalents (1 egg ≈ 50g) so you can weigh instead of counting.
Extreme Scaling (above 4×)
Beyond 4×, consider splitting into multiple batches. Bake times, temperatures, and chemical reactions don't scale linearly at extreme ratios.
