Baking at 4,000 feet
At 4,000 ft (1,219 m): reduce each tsp of baking powder by about ⅛ tsp, use ½ tbsp less sugar per cup, add 1½ tbsp liquid per cup, add 1 tbsp flour per cup, and bake 15–25 °F hotter. Water boils at about 204 °F.

Starting points, not guarantees. Make one batch, note what happened, then fine-tune. Start checking doneness at the shorter time.
What changes at 4,000 feet
Air pressure here is about 86% of sea level. Leavening gases expand further, moisture evaporates faster and water boils around 204 °F, so cakes rise and sink, cookies spread and bakes dry out unless the recipe is rebalanced.

Questions bakers ask
How do I adjust a recipe for 4,000 feet?
Reduce each teaspoon of baking powder or soda by about ⅛ tsp, use about ½ tbsp less sugar per cup, add about 1½ tbsp liquid per cup, add 1 tbsp flour per cup, and bake 15–25 °F hotter for 5–8 minutes less per 30 minutes.
What temperature does water boil at 4,000 feet?
About 204 °F (96 °C), roughly 1 °F lower for every 500 feet of elevation.
Do I need to adjust yeast bread at 4,000 feet?
Yes, lightly: use about 25% less yeast, expect faster rises and add a little water if the dough feels stiff.
