Note: This recipe is for a double layer cake. If you'd like to make only one layer of cake, cut the recipe in half.


Preheat the oven to 350°F and grease a circular cake pan.


Whisk together the dry cake ingredients in a bowl.


Using a separate, large bowl, blend the wet cake ingredients together.


Slowly pour the wet ingredient mixture into the dry ingredients until well combined.


Pour half of the cake mix into the greased cake pan and bake for 15 minutes or until the center is completely done.
Note: You can test to see if it is done by inserting a toothpick into the center. If it comes out clean, it is done.


One this layer of cake is done, remove from the oven and allow to completely cool.
Note: you can speed up this process by cooling it in the fridge or freezer.


While the cake is cooling, make your peanut butter cups, chocolate ganache, and peanut butter frosting.


Repeat the previous steps with the 2nd 1/2 of the batter to create the second layer of cake.


Once completely cool, remove the bottom cake layer onto the sheet you plan on presenting the cake on.


Pour the 1/2 of the chocolate ganache over this layer, making sure not to spill it over the edges.


Pipe about 1/3 of the peanut butter frosting on top of the ganache and spread evenly.


Add the second layer of keto chocolate cake on top of the ganache and peanut butter frosting layers.


Pipe 90% of the remaining frosting onto the cake and smooth evenly.


Drizzle the remaining chocolate ganache on top of the cake and allow to pour over the sides.


Use the remaining bit of peanut butter frosting to pipe 6 decorative swirls onto the cake and add a keto chocolate peanut butter cup on top of each.


For garnish, sprinkle a chopped up peanut butter Quest cookie on top.


Serve your keto chocolate peanut butter cake and enjoy!
