Substituting instant coffee for espresso powder
I have a recipe that i'm currently making for mocha cupcakes. the recipe calls for 1 1/2 teaspoon of espresso powder, since the espresso powder has a richer coffee flavor should i double it since im using just regular instant coffee? i want to be able to taste the coffee and not just plain chocolate, any suggestions?
Also the icing that goes with these cupcakes calls for 1 1/2 teaspoons of espresso powder should i do the same with the cupcake mix and double?
