Ingredients

• 3 cups cake flour
• 1 tablespoon baking powder
• 1 teaspoon salt
• ½ cup unsalted butter, softened
• 1 ¼ cups light brown sugar, packed
• 2 teaspoons vanilla extract
• ½ cup vegetable oil
• ¾ cup creamy peanut butter
• 4 large eggs
• 1 ¼ cups whole milk

How To Make Peanut Butter Sheet Cake

Step 1: Preheat the Oven

Start by preheating your oven to 350°F (175°C). This ensures that your cake bakes evenly and rises beautifully.

Step 2: Prepare the Baking Pan

Grease a sheet pan (approximately 13×18 inches) with a little butter or non-stick spray. You can also line it with parchment paper for easier removal once the cake is done.

Step 3: Mix the Dry Ingredients

In a large bowl, sift together the cake flour, baking powder, and salt. Mixing the dry ingredients first helps ensure even distribution of the leavening agent and salt throughout the flour.

Step 4: Cream Butter and Sugar

In a separate mixing bowl, cream the softened unsalted butter and light brown sugar together until light and fluffy. This process typically takes about 3-4 minutes using an electric mixer. The mixture should be pale in color and have a smooth texture.

Step 5: Add the Wet Ingredients

Next, add the vegetable oil, creamy peanut butter, and vanilla extract to the butter and sugar mixture. Mix until well combined. You want the batter to be smooth and creamy.

Step 6: Incorporate the Eggs

Add the eggs one at a time, mixing well after each addition. This will help to fully incorporate the eggs into the batter, ensuring a uniform texture throughout your cake.

Step 7: Combine Dry and Wet Ingredients

Gradually add the dry ingredient mixture to the wet ingredients, alternating with the whole milk. Start and end with the flour mixture (flour, milk, flour, milk, flour). Mix until just combined; be careful not to overmix, as this can lead to a dense cake.

Step 8: Pour and Smooth

Pour the batter into the prepared sheet pan, smoothing the top with a spatula to ensure even baking.

Step 9: Bake

Place the sheet pan in the preheated oven and bake for about 25-30 minutes, or until a toothpick inserted into the center comes out clean. The edges should be lightly golden, and the center should spring back when touched.

Step 10: Cool Before Serving

Once baked, remove the cake from the oven and let it cool in the pan for about 10 minutes. Then, transfer it to a wire rack to cool completely before icing or serving.

Expert Tips

• Use room temperature ingredients for the best results. Let your butter, eggs, and milk sit out for about 30 minutes before using.
• For an extra nutty flavor, you can toast the peanuts and sprinkle them on top of the cake once cooled.
• Be cautious not to overmix the batter, as this can create a tough texture.
• Store any leftover cake in an airtight container at room temperature for up to three days, or in the fridge for up to a week.

Variations and Customizations

• Add chocolate chips or chunks to the batter for a delicious combination of peanut butter and chocolate.
• Top the cooled cake with a chocolate frosting for an indulgent twist, or keep it simple with a dusting of powdered sugar.
• Incorporate a swirl of your favorite fruit jam or jelly into the batter for a fruity contrast.
• For a more vibrant cake, consider adding a swirl of peanut butter frosting on top.

How to Store Leftovers

To keep your Peanut Butter Sheet Cake fresh, store any leftovers in an airtight container. This cake can be kept at room temperature for up to three days, depending on your climate. If you prefer your cake chilled, you can store it in the refrigerator, where it will last for up to a week. Just remember to bring it to room temperature before serving to enjoy the full flavor and texture.
