FAQs
Q: Can I make these without boxed mixes?
A: Yes. Use your favorite homemade brownie and cookie dough recipes and layer them the same way.
Q: Do I need to thaw the cookie dough?
A: It helps. Soft cookie dough spreads easier. If frozen, press it in small pieces and flatten by hand.
Q: Can I use a glass baking dish?
A: Yes. Reduce baking time slightly and watch for doneness. Oven times can change with glass pans.
Q: How do I know when they are done?
A: A toothpick inserted near the center should come out with a few moist crumbs, not raw batter.
Q: Can I cut them small for a party?
A: Yes. Chill them first for cleaner cuts, then slice into small squares.
