Now that we've established the problem, let's get to the solution. One way to fix dry brownies is to add a glaze - think of it like a hair mask for your baked goods. Simply mix together some powdered sugar, milk, and a pinch of magic (just kidding, it's actually vanilla extract), and drizzle it over your brownies.
If a glaze isn't your thing, you can also try rehydrating your brownies by placing them in an airtight container with a slice of fresh fruit, like an apple or an orange. The moisture from the fruit will seep into the brownies, making them soft and chewy again - it's like a mini-vacation for your taste buds!
And for those of you who are feeling extra adventurous, you can even try re-baking your brownies with a splash of liquid gold (aka melted chocolate). Just be careful not to overdo it, or you'll end up with a batch of brownies that are more like chocolate pudding than, well, brownies.
