Cool fully before storing. Most baked desserts keep at room temperature in an airtight container for 2–3 days, or in the fridge for up to 5 days. Cream- or custard-based desserts must go in the fridge within 2 hours; reheat gently or serve cold per the recipe.

Can I substitute ingredients in Espresso-Infused Dark Chocolate Brownie Bars?

How do I scale Espresso-Infused Dark Chocolate Brownie Bars for a different number of people?

The recipe is written for 16 servings. Multiply each ingredient by (your serving target / 16). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
