Frequently Asked Questions (FAQs)
-
Can I use homemade brownies instead of a box mix?
Yes, just make sure the pan size is the same (9×13) so the layers fit properly. -
Can I use crunchy peanut butter?
You can, but the texture will be less smooth—some people like the added crunch. -
Can I make these without the ganache?
Yes, but the ganache helps balance the sweetness of the peanut butter layer. -
Can I replace semisweet chocolate chips with milk or dark chocolate?
Absolutely choose your favorite chocolate type, just keep the measurements the same. -
Do I have to chill the brownies before cutting?
Yes, chilling helps the ganache set and makes slicing cleaner. -
Can I make them ahead of time?
Yes, they can be made up to 3 days ahead and stored in the fridge. -
Can I make them gluten-free?
Yes, just use a gluten-free brownie mix or your favorite gluten-free brownie recipe. -
Why is my ganache grainy?
The chocolate may have seized from overheating. Stir gently and avoid boiling the cream. -
Can I double the recipe for a larger batch?
Yes, just use two pans instead of one for even baking. -
Can I add toppings like chopped peanuts or sea salt?
Definitely sprinkle on top of the ganache before it sets for extra flavor and texture.
