How to Bake Peanut Butter Sheet Cake with Frosting

Step 1: Warm Up the Oven

Crank the oven to a cozy 325F (163C). Grab your 9×13-inch baking pan and give it a quick spray with cooking oil to prevent any sticky situations.

Step 2: Mix the Cake Magic

Grab your mixing bowl and electric mixer. Blend the softened butter and peanut butter until they become best friends and look super smooth.

• Eggs
• Cake mix
• Water

Whip everything together on medium speed for 2 minutes until the batter looks silky and inviting. Pour this creamy mixture into your prepared pan.

Step 3: Bake to Perfection

Slide the pan into the oven and let it bake for 40 minutes. To check if it’s done, stick a toothpick in the center – it should come out clean.

Let the cake cool down completely before dressing it up with frosting.

Step 4: Create Dreamy Frosting

In another bowl, cream together the softened butter and peanut butter until they’re well blended.

• Confectioners sugar
• Vanilla extract
• Milk

Whip until the frosting becomes light and fluffy. If it seems too thick, splash in a bit more milk to get that perfect spreadable consistency.

Step 5: Frost with Love

Once the cake has cooled, spread that luscious peanut butter frosting all over the top, making sure to cover every delicious inch.

Step 6: Slice and Celebrate

Cut into 12-15 slices and get ready to enjoy a slice of pure peanut butter heaven!

Tips to Perfect Peanut Butter Sheet Cake with Frosting

• Use exact measurements for ingredients to ensure the cake's perfect texture and taste.
• Let butter and eggs sit at room temperature before mixing for smoother, more even batter.
• Insert a toothpick in the center; if it comes out clean with no wet batter, the cake is fully baked.
• Adjust milk quantity gradually to create a spreadable, creamy frosting that's not too thick or thin.
• Keep the cake covered at room temperature for up to 3 days or refrigerate for longer freshness.

Variations on Peanut Butter Sheet Cake with Frosting

• Chocolate Chip Crunch: Fold 1 cup of chocolate chips into the cake batter for extra richness. Sprinkle crushed peanuts on top of the frosting for added texture and crunch.
• Banana Peanut Butter Remix: Mix 2 mashed ripe bananas into the cake batter for moisture. Top the frosted cake with sliced bananas and a drizzle of honey.
• Salted Caramel Upgrade: Swirl salted caramel sauce over the frosting. Garnish with caramel pieces and a light sprinkle of sea salt for a gourmet touch.
• Nutella Swirl Edition: Create a marbled effect by swirling Nutella into the cake batter before baking. Garnish the frosted cake with chocolate shavings and chopped hazelnuts.

Best Pairings for Peanut Butter Sheet Cake with Frosting

• Pair with Creamy Milk Companion: Cold, whole milk complements the rich peanut butter cake perfectly, cutting through its dense sweetness and providing a smooth, refreshing contrast.
• Enhance with Chocolate Harmony: Serve alongside dark chocolate squares or mocha-flavored coffee, which intensify the nutty cake's deep flavor profile and add sophisticated depth.
• Garnish with Nutty Crunch: Sprinkle chopped roasted peanuts or almonds on top of each slice to introduce extra texture and amplify the cake's natural nuttiness, creating a delightful sensory experience.
• Balance with Fruity Brightness: Add a small side of fresh strawberries or raspberry compote to introduce a tangy, light element that helps offset the cake's richness and provides a palate-cleansing effect.

How to Store Peanut Butter Sheet Cake with Frosting

Store covered in an airtight container for up to 5 days. Wrap the cake tightly with plastic wrap or aluminum foil to prevent drying out and maintain moisture.

Slice the cake into individual portions, wrap each piece in plastic wrap, then place in a freezer-safe container. Freeze for up to 3 months for best quality and taste.

Remove frozen cake from the freezer and let it sit at room temperature for 1-2 hours. Alternatively, place in the refrigerator overnight for gradual thawing.

Warm individual slices in the microwave for 15-20 seconds on medium power. For a crisp edge, use the oven by heating at 300F for 5-7 minutes, which helps restore the cake’s original texture and warmth.
