Ingredients List

Creating the perfect peanut butter cake starts with quality ingredients that work in harmony to deliver that signature nutty richness and tender crumb. Here’s everything you’ll need:

For the Cake:

• 2 cups all-purpose flour (substitute: 1¾ cups + ¼ cup almond flour for extra nuttiness)
• 1¾ cups granulated sugar (substitute: 1½ cups coconut sugar for deeper flavor)
• ¾ cup creamy peanut butter (room temperature – natural or regular work equally well)
• ½ cup unsalted butter, softened (substitute: ½ cup coconut oil for dairy-free option)
• 3 large eggs, room temperature
• 1 cup whole milk (substitute: oat milk or almond milk for plant-based version)

• ½ teaspoon salt
• ¼ cup hot water

For the Peanut Butter Frosting:

• 1 cup creamy peanut butter
• ½ cup unsalted butter, softened

The beauty of this recipe lies in its flexibility – each ingredient can be customized to accommodate dietary preferences without compromising the cake’s signature taste and texture.

Step-by-Step Instructions

Step 1: Prepare Your Kitchen for Success

Preheat your oven to 350°F (175°C) and position the rack in the center. Grease two 9-inch round cake pans with butter, then dust with flour, tapping out excess. This double protection ensures your peanut butter cake releases perfectly every time. Line the bottom with parchment paper for extra insurance – trust me, this small step prevents heartbreak later.

Pro Tip: Place a kitchen towel under your mixing bowl to prevent it from sliding around during mixing. This simple hack keeps everything stable and makes the process smoother.

Step 2: Create the Perfect Peanut Butter Base

In a large mixing bowl, cream together the softened butter and peanut butter for 3-4 minutes using an electric mixer on medium speed. The mixture should become light and fluffy – this aeration is crucial for a tender cake. Gradually add the sugar and beat for another 2 minutes until the mixture is pale and increased in volume.

Add eggs one at a time, beating well after each addition. The mixture might look slightly curdled – don’t worry, this is normal and will smooth out once you add the dry ingredients. Beat in the vanilla extract.

Expert Insight: Room temperature ingredients blend more easily and create a more uniform batter, resulting in an even cake texture throughout.

Step 3: Build the Perfect Batter Balance

In a separate bowl, whisk together flour, baking powder, and salt. This ensures even distribution of leavening agents. Add the dry ingredients to the peanut butter mixture in three additions, alternating with the milk in two additions. Begin and end with the flour mixture.

Mix on low speed just until combined – overmixing develops gluten and creates a tough cake. Finally, stir in the hot water, which helps bloom the peanut butter flavors and creates extra moisture.

Game-Changing Tip: The hot water might seem unusual, but it’s the secret to an incredibly moist peanut butter cake that stays fresh for days.

Step 4: Bake to Golden Perfection

Divide the batter evenly between prepared pans – use a kitchen scale for precision if you have one. Smooth the tops gently with an offset spatula. Bake for 35-40 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs attached.

The cakes are done when they spring back lightly when touched and start to pull away from the sides of the pan. Don’t open the oven door for the first 30 minutes to prevent collapsing.

Temperature Check: Internal temperature should reach 200-205°F when fully baked.

Step 5: Assemble Your Masterpiece

Cool cakes in pans for 10 minutes, then turn out onto wire racks to cool completely. While cooling, prepare the frosting by beating peanut butter and butter until smooth, then gradually adding powdered sugar, cream, vanilla, and salt until you achieve a spreadable consistency.

Place one layer on your serving plate, spread frosting evenly across the top, then add the second layer. Apply a thin crumb coat, refrigerate for 15 minutes, then finish with the remaining frosting using smooth strokes or decorative swirls.

Common Mistakes to Avoid

Temperature Troubles:

• Mistake: Using cold ingredients straight from the refrigerator
• Solution: Plan ahead and bring eggs, butter, and milk to room temperature 1-2 hours before baking

Mixing Mishaps:

• Mistake: Overmixing the batter, resulting in tough, dense cake
• Solution: Mix just until ingredients are combined – lumps are okay and will disappear during baking

Measurement Errors:

• Mistake: Eyeballing ingredient quantities, especially flour
• Solution: Use a kitchen scale for precision, or properly spoon and level flour measurements

Baking Blunders:

• Mistake: Opening the oven door too early or too frequently
• Solution: Trust the process and only check after 30 minutes using the oven light

Frosting Failures:

• Mistake: Frosting a warm cake, causing melting and sliding
• Solution: Ensure cake is completely cool before applying any frosting

Storage Slip-ups:

• Mistake: Storing frosted cake uncovered, leading to dry edges
• Solution: Cover with a cake dome or plastic wrap, avoiding direct contact with frosting

Storing Tips for the Recipe

Maximize freshness and extend the life of your delicious peanut butter cake:

Short-term Storage (1-3 days):

• Store covered at room temperature in a cool, dry place
• Use a cake keeper or invert a large bowl over the cake

Long-term Storage (up to 1 week):

• Wrap individual slices in plastic wrap and store in the refrigerator

Freezer Storage (up to 3 months):

• Wrap unfrosted cake layers tightly in plastic wrap, then aluminum foil
• Freeze frosting separately in airtight containers
• Label with date and contents
• Thaw overnight in refrigerator before assembling

Make-Ahead Tips:

• Bake cake layers up to 2 days in advance and store covered
• Prepare frosting up to 3 days ahead and re-whip before using

FAQs

Q: Can I make this peanut butter cake without eggs? A: Absolutely! Replace each egg with ¼ cup unsweetened applesauce or 1 tablespoon ground flaxseed mixed with 3 tablespoons water. Let the flax mixture sit for 5 minutes before using. The cake will be slightly denser but equally delicious.

Q: What’s the difference between natural and regular peanut butter in this recipe? A: Regular peanut butter contains stabilizers that help create a smoother cake texture, while natural peanut butter provides a more intense nutty flavor. Both work well, but if using natural, make sure it’s well-stirred before measuring.

Q: Why did my cake sink in the middle? A: This usually happens from overmixing the batter (developing too much gluten), opening the oven door too early, or incorrect oven temperature. Use an oven thermometer to verify accuracy and avoid opening the door for the first 30 minutes.

Q: Can I make this as a sheet cake instead of layers? A: Yes! Pour the batter into a greased 9×13-inch pan and bake for 40-45 minutes. This creates perfect squares for casual gatherings and reduces assembly time.

Q: How can I tell when the cake is perfectly done? A: Look for three signs: the cake springs back when lightly touched, it starts pulling away from the pan sides, and a toothpick inserted in the center comes out with just a few moist crumbs. Internal temperature should reach 200-205°F.

Q: My frosting is too thick/thin – how do I fix it? A: For thick frosting, add heavy cream 1 tablespoon at a time until you reach desired consistency. For thin frosting, add powdered sugar ¼ cup at a time. Always beat well between additions to assess texture.

Q: Can I double this recipe for a larger crowd? A: Certainly! Double all ingredients and divide between four 9-inch pans or two 9×13-inch pans. Baking time may increase by 5-10 minutes, so test with a toothpick for doneness.
