Concentrated almond flavoring used in cookies, cakes, and frostings. Stronger than vanilla, so it is usually used in smaller amounts.
Substitutes
Vanilla Extract — 1.5:1 (use 1.5x vanilla for each part almond extract). Vanilla extract provides sweet warmth that fills the role of almond extract in most baking recipes. The distinctive marzipan flavor will be missing, but the result is still delicious.
Amaretto — 4 tsp amaretto per 1 tsp almond extract. Amaretto liqueur is made from almonds and carries the same sweet, nutty flavor in diluted form. Use 4 times the amount and reduce other liquids slightly.
Almond Flour — 2 tbsp almond flour per 1 tsp extract (reduce other dry ingredients). Almond flour provides subtle almond flavor through actual nut content rather than extract. The effect is milder, so best for recipes where almond is a supporting flavor.
Coconut — 1:1. Coconut extract provides a similarly sweet, tropical nuttiness that works in cookies, cakes, and frostings. The flavor profile is different but the sweetness intensity matches well.
