Ingredients List

    • 2 cups all-purpose flour
    • 1½ cups granulated sugar
    • ¾ cup creamy peanut butter
    • ½ cup unsalted butter, softened
    • 3 large eggs, room temperature
    • 1 cup whole milk
    • 2 teaspoons baking powder
    • 1 teaspoon vanilla extract
    • ½ teaspoon salt

For the Frosting:

    • 1 cup creamy peanut butter
    • ½ cup unsalted butter, softened
    • 3 cups powdered sugar
    • ⅓ cup heavy cream
    • 1 teaspoon vanilla extract
    • Optional: ¼ cup chocolate chips for garnish
    • Optional: Crushed peanuts for topping

Timing / Cooking Schedule

Prep time: 20 minutes

Cooking time: 35 minutes

Total time: 55 minutes (plus cooling time)

This timeline makes it perfect for weekend baking projects or advance preparation for events. The cooling period is crucial, so plan for an additional 1-2 hours before frosting.

Step-by-Step Instructions

Step 1: Preheat your oven to 350°F (175°C). Grease two 9-inch round cake pans with butter and dust lightly with flour, tapping out excess. This prevents sticking and ensures easy release.

Step 2: In a large mixing bowl, cream together the softened butter, peanut butter, and sugar using an electric mixer on medium speed for 3-4 minutes until light and fluffy. This aeration creates the cake's tender texture.

Step 3: Add eggs one at a time, beating well after each addition. Scrape down the bowl sides between additions to ensure even incorporation. Mix in vanilla extract.

Step 4: In a separate bowl, whisk together flour, baking powder, and salt. Gradually add dry ingredients to the wet mixture in three parts, alternating with milk, beginning and ending with flour. Mix just until combined—overmixing develops gluten and creates tough cake.

Step 5: Divide batter evenly between prepared pans. Tap pans gently on the counter to release air bubbles. Bake for 30-35 minutes until a toothpick inserted in the center comes out clean and edges pull away slightly from pan sides.

Step 6: Cool cakes in pans for 10 minutes, then turn out onto wire racks to cool completely. Never frost warm cake—the frosting will melt and slide off.

Step 7: For frosting, beat peanut butter and butter together until creamy. Gradually add powdered sugar, alternating with heavy cream, beating until smooth and spreadable. When working with this peanut butter cake recipe, ensure your frosting reaches a spreadable consistency by adjusting cream amounts as needed.

Step 8: Place one cake layer on a serving plate, spread frosting evenly, top with second layer, then frost top and sides. Garnish with optional toppings if desired.

Tips, Variations, or Cooking Advice

Dietary Modifications: For a gluten-free version, substitute with a 1:1 gluten-free flour blend. Use almond butter instead of peanut butter for different flavor profiles or nut allergy accommodations.

Flavor Variations: Add ½ cup mini chocolate chips to the batter for chocolate-peanut butter fusion. Incorporate 1 teaspoon espresso powder to enhance chocolate notes. Try swirling in raspberry jam between layers for fruity contrast.

Frosting Alternatives: Make chocolate ganache frosting by melting 1 cup chocolate chips with ½ cup heavy cream. Cream cheese frosting also pairs beautifully—combine 8 oz cream cheese with ½ cup peanut butter and powdered sugar to taste.

Make-Ahead Strategy: Bake cake layers up to 3 days ahead, wrap tightly in plastic wrap, and refrigerate. Frosting can be made 2 days in advance and stored covered in the refrigerator; bring to room temperature before using.

Common Mistakes to Avoid

Using Cold Ingredients: Room temperature eggs, butter, and milk blend more smoothly, creating better emulsification and a more uniform crumb structure. Set ingredients out 30-60 minutes before baking.

Overmixing the Batter: Once flour is added, mix only until just combined. Overmixing develops excessive gluten, resulting in dense, tough cake rather than the desired tender texture.

Incorrect Oven Temperature: Use an oven thermometer to verify actual temperature. Too-hot ovens create domed, cracked tops with undercooked centers, while too-cool ovens produce dry, dense cakes.

Skipping Pan Preparation: Properly greased and floured pans are essential. For extra insurance, line pan bottoms with parchment paper circles.

Frosting Warm Cake: Patience is critical. Frosting applied to warm cake melts, creates sliding layers, and incorporates crumbs throughout. Always cool completely—at least 2 hours.

Storage / Leftovers Tips

Store your completed cake in an airtight container or under a cake dome at room temperature for up to 3 days. For longer storage, refrigerate for up to 1 week, though this may slightly firm the texture. Before serving refrigerated cake, let it sit at room temperature for 30 minutes to restore optimal texture and flavor.

For freezing, wrap unfrosted cake layers individually in plastic wrap, then aluminum foil, and freeze for up to 3 months. Frosted cake can also be frozen—place in the freezer uncovered for 1 hour until frosting firms, then wrap carefully. Thaw overnight in the refrigerator, unwrapping before completely thawed to prevent condensation from damaging frosting.

When working with this peanut butter cake recipe easy method, leftover slices can be individually wrapped and frozen for quick single servings. Microwave frozen slices for 20-30 seconds for a warm, fresh-baked taste that rivals the original.
