Tips & Variations
- Ingredient substitutions: If you don’t have sour cream, Greek yogurt works beautifully as a substitute. For a dairy-free version, you can use almond milk yogurt.
- Optional variations: Try adding a teaspoon of lemon zest to the batter for a citrus twist, or mix in some chopped pecans or walnuts for added crunch.
- Storage or reheating tips: Store any leftovers in an airtight container at room temperature for up to 2 days. To reheat, pop a slice in the microwave for about 10-15 seconds.
