Each year for my birthday, my grandmother would make us each a homemade cake to celebrate our day. My grandmother quickly realized that she never really had to ask me which cake was going to be my choice. Every year, I always requested her homemade peanut butter cake with peanut butter frosting. It really was her best homemade cake. It is perfect for feeding a crowd. We sometimes cut our cakes into smaller finger sized pieces when we are feeding more than just immediate family. You can easily get quite a few smaller pieces from a traditional sized cake pan. I know some make an old fashioned peanut butter sheet cake when serving a crowd. Sheet pan cakes are great but there is something about a thick moist cake topped with a layer of thicker frosting.
This recipe is an old fashioned cake recipe filled with so much flavor. She has been making this same recipe for years. I thought the recipe was very tedious so I never tried to make it myself. I can’t believe I have waited this long to make her homemade peanut butter cake. I have now made this recipe a few times and each and every time, my family has gobbled it up. They now have deemed it their favorite cake.It was not difficult to make and took very little time. Sure a peanut butter cake mix would be a blessing for a quick dessert but homemade desserts are always the best. The question always lingers in my mind as to why manufacturers have yet to make a good peanut butter cake mix. Maybe someday they will excite all of us peanut butter fans with such a product.
How do you make Peanut Butter Cake?
All that is needed to make this recipe is some creamy peanut butter and some basic ingredients you most likely have on hand. Grab some of the store brand peanut butter, it will work best. It is always creamy and has the most oil content. So it is perfect for this cake. Peter Pan or Skippy will work fine too.

Tips for Making Peanut Cake
I always heavily butter my baking dish. I also add a dusting of flour. This always keeps the cake from sticking.
Bake for long enough for your center to be baked thoroughly. Ovens and baking time can vary from oven to oven. Just use the toothpick trick. If the toothpick comes out clean, your cake is done.
Be sure to use softened butter for your peanut butter frosting. It will blend much better with the peanut butter and make the texture of your frosting creamier. Add a couple more drops of milk if you would like your frosting thinner.
Toss your cake in the refrigerator, it tastes amazing chilled too.
If storing your cake at room temperature, cover it to keep fresh.
Enjoy with a large glass of milk. Milk with this cake is amazing.

Made this for Easter dinner. It was an instant hit… Moist, peanut buttery, almost decadent… Simply amazing!! It was an instant favorite!!
I haven’t tried recipe yet,it is the only recipe I have found that reads as the best! I was wondering if I use the peanut butter with the extra oil in it, (you have to stir it, )can I omit the butter?
I cut your recipe in half and baked the cake in an 8 x 8 glass dish. Based on other recommendations, I reduced the temperature to 325. It’s a moist delicious cake! The peanut butter frosting is sweet enough but not over sweet. Thanks for a great recipe!
Can this cake be made into cupcakes, it is delicious. I would like to make a cupcake cake for my granddaughter.
