How to Make The Best Peanut Butter Cake
Step 1: Preheat the Oven
Preheat your oven to 350F (180C or 160C fan-forced). This ensures that your cakes bake evenly.
Step 2: Prepare Your Pans
Line the bottom of two round cake pans with baking paper. Lightly grease and flour the sides to prevent sticking.
Step 3: Combine Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside this mixture for later use.
Step 4: Mix Wet Ingredients
In a large bowl, beat together the vegetable oil, light brown sugar, and smooth peanut butter until smooth. Incorporate the eggs and vanilla extract until combined.
Step 5: Add Milk
Using a hand-held metal whisk, mix in the milk until fully integrated into the peanut butter mixture.
Step 6: Combine Mixtures
Gradually whisk in the flour mixture until just combined. Avoid overmixing to keep your cake light.
Step 7: Bake
Divide the batter evenly between the prepared pans. Bake them on the middle rack for about 28–33 minutes, or until a toothpick comes out clean from the center.
Step 8: Cool Cakes
Once baked, cool the cakes completely before moving on to frosting.
Step 9: Make Peanut Butter Frosting
In a large bowl using an electric mixer, beat softened unsalted butter until smooth. Add cream cheese followed by peanut butter. Gradually mix in powdered sugar while adjusting sweetness as desired.
Step 10: Assemble Cake Layers
Ensure layers are cool. If domed, level tops with a serrated knife. Place one layer on your serving plate bottom side up. Frost generously before adding the second layer on top.
Step 11: Final Frosting Touches
Seal crumbs with a thin layer of frosting around sides before applying swirls of frosting on top and sides. Optionally top with candy pieces like Reese’s Cups for extra appeal.
Enjoy this delightful dessert that celebrates all things peanut butter!

- Measure Flour Accurately: Use the spoon and level method to avoid adding too much flour, which can affect texture.
- Cool Cakes Completely: Allow cakes to cool fully before frosting; this prevents melting and sliding frosting.

- Incorrect oven temperature: Always preheat your oven to 350F (180C) before baking. An unheated oven can lead to uneven baking.

- Not cooling cakes properly: Allow the cakes to cool completely before frosting. Frosting warm cakes can cause melting and messiness.
