HOW DO YOU MAKE CHOCOLATE GOOEY BUTTER CAKE?
To make this gooey butter cake, simply mix up your ingredients for the delicious cake crust and press it firmly into the pan. The best step is next, scatter your peanut butter cups all over the crust before mixing your next set of ingredients.
Once you’ve made your smooth peanut butter mixture, pour it over the peanut butter cups and bake until done. Allow to cool then serve topped with whipped cream and pieces of peanut butter cups. This chocolate peanut butter cake will be a hit no matter when or where you serve it!

This peanut butter cake is rich (in a very good way) so be warned that serving in smaller squares is strongly suggested. Never fear, your gooey butter cake can be frozen for later or even saved for four days in the fridge.

I love serving this peanut butter cake with a lightly sweetened whipped cream and pieces of peanut butter cups. I suggest looking for the bite sized peanut butter cups in the candy aisle. If you can’t locate those, cutting larger peanut butter cups into fourths works as well.

HOW DO YOU KNOW IF THE WHIPPED CREAM YOU’RE BUYING IS LIGHTLY SWEETENED?
There are many types of whipped cream products on the market, including aerosol cans, heavy cream in cartons you whip yourself, and frozen whipped topping. Typically whipped topping and the aerosol can whip cream contain sugar. However, to ensure you get the level of sweetness you prefer, I suggest making your own as it’s healthier, easy, and tastier, in my opinion.

HOW LONG WILL CHOCOLATE GOOEY BUTTER CAKE LAST?
If left at room temperature, your cake will last around two days. If refrigerated, it will last around 4 days. If you freeze it, for best taste, eat within the next month or so. Of course, it’s always best to eat the cake the day it’s prepared for the freshest taste.

I promise you that I will end up making this cake quite a few times this year. It was SO easy to make and was a huge hit with my guests. Of course, it was a huge hit with the kids and husband as well, not to mention, I definitely ate my fair share!
