The frosting on this cake isn't super pretty, but the entire thing is a peanut butter lover's DREAM. A moist yellow cake soaked in sweet peanut butter sauce and topped with buttery peanut butter frosting! I used good ol' fashioned processed, sweetened peanut butter for this, so your mileage may vary if you use the natural sort.

Serves: 9-12
Ingredients
Cake Ingredients:
  • 1/2 cup butter
  • 1/2 cup water
  • 1 cup + 2 tablespoons cake flour
  • 1 cup white sugar
  • 1 egg, lightly beaten
  • 1/4 cup sour cream
  • 1/4 teaspoon almond extract
  • 1/4 teaspoon vanilla extract
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
Peanut Butter Sauce Ingredients:
  • 1/2 cup peanut butter
  • 1 tablespoon powdered sugar
  • 6 tablespoons cup milk
  • 2 tablespoons light corn syrup
Peanut Butter Icing Ingredients:
  • 1/2 cup butter, softened
  • 1 cup creamy peanut butter
  • 3 tablespoons milk, or as needed
  • 2 cups confectioners' sugar
  • chopped peanuts or gold sprinkles for topping, optional
Instructions
  1. Make the cake: Preheat the oven to 375 degrees and grease an 8-inch square baking pan (I use Wilton's Cake Release to grease my whole pan and then place a sheet of greased parchment in the bottom of the pan). In a medium saucepan over medium heat, bring the butter and water to a boil. In the meantime, in a separate large bowl, whisk together the cake flour and sugar before adding the egg, sour cream, almond extract, vanilla extract, baking soda, and salt. Mix to combine. While mixing, slowly pour in the boiling butter and water mixture. Mix to combine completely. Your batter will be very runny. Pour the batter into the prepared baking pan. Bake at 375 degrees for 17-22 minutes or until a toothpick inserted in several places comes out with a few moist crumbs. Poke holes in the cake with the handle of a wooden spoon.
  2. Make the peanut butter sauce: Heat the peanut butter in a medium bowl for about 30 seconds. Whisk in powdered sugar and enough milk to reach pouring consistency (I had to use the full amount. It should be sauce-like, so don't be shy about adding more liquid). Pour over the cake and cool completely (I stuck mine in the fridge and it was cool in about an hour).
  3. Make the peanut butter icing: Beat the butter and peanut butter together in a medium bowl until combined. Gradually beat in the powdered sugar. Add milk one tablespoon at a time until all of the sugar is mixed in and the frosting is thick but still spreadable (I needed the full amount). Beat for a few minutes until it’s super fluffy. Spread it on completely cooled cake -- it's not the smoothest or prettiest, but it is the most delicious! Top with chopped peanuts or gold edible sprinkles!

    Julie! I am so happy, as just a random internet person who reads this blog, to know we have something else in common. Your comments about how people need representation in the world resonated with me so much. As someone who grew up in the 80s and 90s, I spent so much of my time convinced my queerness was a death sentence. There were no people like me living happy lives, or living past 40, or sometimes even living at all. But here we are. I am glad you can live your truth and do your thing. <3

    That must have been weighing on you so I am happy you got it off of your chest. It doesn’t matter to me one bit. You are a sweet, religious, animal loving and kind person. That’s all that matters to me. You can bake great too! 👏🏻

    The fool has said in his heart there is no God. Jesus said some will say Lord, Lord and He will say “depart from me , I never knew you”. Your conscience has been seard with a hot iron.

      This is such a lazy misuse of scripture. Who said there is no God? You’re just stringing verses together here that aren’t relevant to the situation.

      Ugh. Please show some consideration. Someone bares her soul to the rest of us ever so bravely and you come up with “your conscience has been seared?” Pituna, this is not the forum for you.

      No no this was a recipe for cake. Seared Conscience is more of an entree.

    Bless you for “speaking truth to powe” and being true to yourself in a way that blesses others.
    You are exemplifying God’s love.
    Whoever does not love does not know God, because God is love.

    Thank you for the delicious recipe and for sharing something so personal. In our society and times, children, teens and adults need all the love and support they can get. Gay, straight, bi, transgender, Christian and not. I am not a Christian but I am a lesbian and this post brightened my day. Thanks for all the lovely posts and sharing your life.

    Julie, THANK YOU for not hiding who you are. I was lucky to come across your website today and I thought, “Wow, there is a person who has finally tapped into who she really is. I wish I could come to know myself so well someday.” There are many lost souls in this world and your genuineness, open-heartedness, and beauty that radiates from the inside out, is remarkable, honorable, and could not be more needed in our current society. I live in shame and hiding for different reasons, but you inspire me. Thank you for being the change I want to see in this world. Let there be a million more people like you in this world, who are open and accepting to everyone. And thank you for all things peanut butter.

    I was surprised to see almond extract in your cake batter! I’m sure it’s fabulous – can’t wait to try this recipe, too 🙂

      Oh yes!! I love adding almond extract to this cake batter. To me, it doesn’t make it a pronounced almond flavor but does give it kind of a bakery finish. Hope you love it!

      You can focus on whatever you want. If what I focus on bothers you — which is what you’re actually saying — you can also feel free to head to another blog.

      Also, do you realize you literally just said the equivalent of, “Get in the kitchen and make me a sandwich” to a woman you don’t even know? Ha bye Chris.

    Saw this clickbait over on Instagram, wandered over to see the big reveal….LOVE it! It resonated a lot with me, as a fellow bisexual Christian(ish – but that’s a whole different story). I went to Catholic school and fell in love with a female classmate; we were not very good at hiding it, so everyone around us tried to stamp it out. Having someone like you to look up to during that period would have made all the difference in the world. Your students are so lucky to have you!

    ALSO – that peanut butter cake is calling my name 🙂 Can’t wait to try it!

      Thank you so much for your kind words, Becky! I wish people had been more supportive of you in school — you deserved to feel normal and valid! It’s so encouraging to hear that you feel like having a role model would’ve helped you — I hope my students always feel safe being their authentic selves.

    I originally came here for the baking. I was impressed, and made more hopeful for the world, by the way you talked about your sister’s experience. I am strengthened by your honesty. And I am educated by the kindness and wisdom you employ dealing with dissenting views and trolls. As a 50 something gay man,out and comfortable with himself (but perhaps not as comfortable as I thought), you’ve shown me I still have things to learn about myself and how to deal with the world. Keep up the good work….oh yeah, and the good baking too. You go girl, good on you!

    I very much respect your ability to mix important thoughts and issues among your delicious recipes. Even more so now. I came over today to see what you were up to as I struggle with how to intermingle my interest in politics, race, food and writing. Though I come from atheist/cis-gendered old lady perspective, I admire your convictions and values. I’m grateful and inspired by how much of yourself you share with us. I hope I can achieve even a small semblance of what you do here. UGH!Now back to redesigning my website…good thing I have someone to look up to I was feeling a bit discouraged. Your post completely reenergized me. Thank You!
