CAN I USE ANOTHER FROSTING?
If you don’t want to have peanut butter on peanut butter you can absolutely add another frosting of your choice.
Some of our other favorites include just a regular buttercream frosting and a chocolate buttercream, chocolate and peanut butter are so good together so that is another one we use all the time.
CAN I USE CHUNKY PEANUT BUTTER IN THE CAKE?
This is a great option, while we usually use creamy peanut butter for this recipe you can use chunky! This will give some texture to the cake with the chunks of peanuts.
You can also choose to do that with the frosting if you’d like, if you are wanting to have the chunks of peanuts in there too!
WHAT CAN I TOP THIS WITH?
If you want to add some chopped peanuts or chocolate chips to the top of the cake those are great toppings. You can also drizzle it with some chocolate syrup or hot fudge to give it a little chocolate aspect to the cake.
HOW TO STORE:
This can be stored covered at room temperature where it will keep for up to 3-4 days.
This can also be frozen, placed in a freezer container with layers separated by parchment paper and it will keep frozen for up to 3 months.
To defrost, remove to the refrigerator overnight then let it come to room temperature before serving.
TIPS AND TRICKS:
- You can use another frosting if you prefer, chocolate or regular buttercream are great.
- Top with peanuts, chocolate chips, hot fudge sauce, or chocolate syrup.
- This can be cut in half and baked in a 9×9-inch pan if desired.
- This can be frozen, see my tips above.
