Ingredients in Peanut Butter Sheet Cake with Peanut Butter Frosting

Here’s the magic of this cake—it’s made with just a few everyday ingredients, but the results are out of this world. Let’s break it down:

Peanut Butter: The star of the show! It gives the cake its rich, nutty flavor and makes the frosting perfectly smooth and creamy.

Butter: Adds moisture and richness to the cake, making it melt in your mouth.

Sugar: A little sweetness to balance out the peanut butter and give the cake that perfect texture.

Eggs: For structure and fluffiness in the cake. They help bind everything together.

Flour: The base of the cake that gives it that soft, light texture we all love.

Baking Powder: To give the cake the right rise and texture.

Milk: Adds moisture to the cake and helps bring the batter together.

Vanilla Extract: A splash of this gives the cake that warm, inviting aroma and flavor.

For the frosting:

Peanut Butter: A double dose of peanut butter! The frosting wouldn’t be the same without it.

Butter: Again, it adds a creamy, smooth texture to the frosting.

Powdered Sugar: This sweetens the frosting and gives it the perfect consistency for spreading.

Vanilla Extract: A touch of vanilla makes the frosting even more irresistible.

Milk: Just enough to make the frosting smooth and spreadable.

(Note: The full ingredients list, including measurements, is provided in the recipe card directly below.)

Instructions

Let’s dive into the steps to create this peanut butter-packed masterpiece:

Preheat Your Oven

Preheat your oven to 350°F (175°C). This step is crucial to ensure even baking and to help your cake come out perfectly.

Mix the Cake Batter

In a large mixing bowl, combine the flour, sugar, and baking powder. In a separate bowl, mix together the peanut butter, butter, milk, eggs, and vanilla extract. Gradually add the wet ingredients to the dry ingredients and stir until everything is just combined. Don’t overmix—it’s all about getting a nice, smooth batter without overworking it.

Bake the Cake

Pour the batter into a greased 9×13-inch baking pan. Spread it evenly, then pop it in the preheated oven and bake for about 30 minutes, or until a toothpick inserted into the center comes out clean. Your kitchen will smell AMAZING!

Prepare the Frosting

While the cake is cooling, let’s make that dreamy frosting. In a large mixing bowl, beat together the peanut butter and butter until creamy and smooth. Add the powdered sugar and vanilla extract, mixing until fully combined. Gradually add in milk until the frosting reaches a spreadable consistency.

Frost the Cake

Once the cake has cooled completely (no one wants melted frosting!), spread the peanut butter frosting evenly over the top. Don’t be shy—add a generous layer!

Serve and Enjoy

Slice it up, serve, and enjoy! Every bite of this peanut butter sheet cake is pure bliss, with that perfect balance of sweetness and nuttiness that will have everyone coming back for more.

How to Serve Peanut Butter Sheet Cake with Peanut Butter Frosting

This cake is perfect on its own, but here are a few ways to elevate the experience:

Fresh Fruit: Serve alongside a fresh fruit salad or some sliced strawberries to balance the richness of the cake.

Ice Cream: A scoop of vanilla or chocolate ice cream makes this cake even more decadent. Think of it as a peanut butter sundae in cake form!

Coffee or Milk: Pair this cake with a warm cup of coffee or a tall glass of milk—either way, it’s a match made in heaven.

Additional Tips

Here are a few extra tips to ensure your peanut butter sheet cake turns out perfectly every time:

Prep Ahead: You can make the cake and frosting ahead of time. Just store them separately in airtight containers and frost the cake when you’re ready to serve.

Mix It Up: Love a little crunch? Add chopped peanuts or peanut brittle to the frosting for some extra texture.

Storage Tips: Store leftovers in an airtight container for up to 3 days. It’s even better the next day as the flavors have had time to meld together.

Double the Batch: Planning a party or need to feed a crowd? Double the recipe and bake it in two 9×13 pans for a larger batch.
