Chef Emma’s Helpful Tips
Make-Ahead Advice: You can make the dough in advance and refrigerate it for up to 24 hours before baking. Just let it sit on the counter for 15 minutes before spreading it in the pan.
Ingredient Swaps: If you need to make this recipe egg-free, try substituting the large egg with 1/4 cup of unsweetened applesauce for a still-delicious result.
Slicing Tricks: For clean cuts, use a sharp knife and get it warmed slightly under hot water, allowing for a smooth and tidy slice.
Storage Suggestions: Store any leftovers in an airtight container at room temperature for up to one week — if they last that long!
