Smart Substitutions:
Don't have exactly what you need? Here's how to pivot without sacrificing flavor:
No lemon cake mix? Use yellow or white cake mix and add an extra 2 tablespoons of lemon zest and 1 teaspoon lemon extract.
Cream cheese alternatives: Greek yogurt cream cheese or Neufchâtel cheese work wonderfully for a lighter version. For dairy-free options, several plant-based cream cheese alternatives will work, though the texture may vary slightly.
Fresh lemon shortage? While fresh is best for the brightest flavor, you can substitute 3 tablespoons of bottled lemon juice. For zest, 1 teaspoon of lemon extract can replace 1 tablespoon of zest in a pinch.
Powdered sugar substitute: Blend granulated sugar in a food processor until fine, then measure what you need (add 1 teaspoon cornstarch per cup for stability).
Butter options: While unsalted butter gives you control over the salt level, salted butter works fine—just omit any additional salt in the recipe. For dairy-free needs, a quality plant-based butter substitute performs well.
