6. Allow the cake to cool for about 10 minutes before serving.
Variations & Tips
If you’re looking to mix things up a bit, try adding a handful of crushed pretzels on top for a salty-sweet twist. You can also substitute the chocolate cake mix for a brownie mix if you’re in the mood for an extra fudgy dessert. For an even richer flavor, use dark chocolate chips in place of the semi-sweet ones. And if peanut butter cups aren’t your favorite, try using caramel-filled chocolates or your favorite candy bars in their place. Remember, baking is all about bringing joy to your loved ones, so feel free to get creative and tailor this recipe to your family’s tastes!
