FAQs
1. Can I use a different box mix for this recipe?
Yes! You can use any brownie mix you prefer. Different brands may have slightly different instructions, but the general method will be the same.
2. How do I know when the brownies are done?
To check if your brownies are done, insert a toothpick in the center. If it comes out with only a few moist crumbs, they’re ready. If it’s wet with batter, they need more time.
3. Can I make these brownies in a smaller pan?
You can, but you’ll need to adjust the cooking time. A smaller pan will require less time to bake, so start checking the brownies a few minutes earlier than the recipe suggests.
4. Can I freeze these brownies?
Yes! Brownies freeze really well. Simply wrap them in plastic wrap or aluminum foil and store them in a freezer-safe bag for up to 3 months.

If you prefer cakier brownies, you can reduce the amount of oil in the box mix or add an extra egg to help create a fluffier texture.

8. How long do brownies need to cool before cutting?
Let the brownies cool for at least 20-30 minutes before cutting them to ensure they set properly and don’t fall apart when sliced.
9. Can I use butter instead of oil?
Yes, you can substitute the oil for an equal amount of melted butter if you prefer. It may give the brownies a slightly different texture and flavor.
