How It Works

At high altitudes, lower air pressure causes baked goods to rise faster and higher, then collapse. Water also evaporates faster and boils at a lower temperature. These adjustments compensate by strengthening the batter structure and slowing the rise.

The Formula

Adjustments scale linearly from 3,000 feet (minimal) to 7,000+ feet (maximum). Per cup of sugar: reduce 1-3 tbsp. Per cup of flour: add 2-4 tbsp. Per cup of liquid: add 2-4 tbsp. Per tsp of baking powder: reduce 1/8 to 1/4 tsp. Oven: increase 15-25 F.

Variables

Altitude (feet above sea level), sugar (cups), flour (cups), liquid (cups), baking powder (tsp), oven temperature (F).

Example

At 5,000 feet with a recipe calling for 1 cup sugar, 2 cups flour, 1 cup milk, 2 tsp baking powder at 350 F: reduce sugar by about 2 tbsp, add about 6 tbsp flour, add about 3 tbsp liquid, reduce baking powder by about 3/8 tsp, and bake at 370 F.

Tips

  • Start with the minimum adjustment and increase if results are not right -- every oven and recipe is different.
  • Greasing and flouring pans well is extra important at altitude because batters stick more.
  • Use large eggs instead of medium -- the extra protein helps structure.
  • Underbake slightly rather than overbake -- things dry out faster at altitude.
  • Keep notes on what works for your specific altitude and recipes.
