Peanut Butter Cake Ingredients

For the Cake
• All-purpose Flour – Provides structure; can substitute with gluten-free flour blend for a gluten-free version.
• Baking Powder – Acts as a leavening agent; ensure it’s fresh for maximum rise.
• Kosher Salt – Enhances flavor; can use table salt but reduce the amount slightly.
• Butter (1 1/2 sticks, softened) – Adds moisture and richness; opt for unsalted for better control over salt levels.
• Brown Sugar – Contributes sweetness and moisture; light brown sugar can be swapped for dark for a milder flavor.
• Granulated Sugar – Offers sweetness; substitute with coconut sugar for a healthier option.
• Peanut Butter – The star of the show; choose creamy for a smooth texture, or crunchy for added bite.
• Sour Cream – Enhances moisture and richness; Greek yogurt can serve as a dairy-free substitute.
• Vanilla Extract – Adds depth of flavor; pure extract works best for optimal taste.
• Large Eggs – Essential for structure and leavening; ensure they are at room temperature for better mixing.
• Milk – Provides moisture; non-dairy options are available if preferred.

For the Frosting
• Cream Cheese (8-oz. block, softened) – Delivers tanginess and creaminess to the frosting; vegan cream cheese is a dairy-free option.
• Powdered Sugar – Adds sweetness and texture; sifting helps avoid lumps for a smooth frosting.
• Heavy Cream – Assists in achieving a fluffy texture; half-and-half offers a lighter alternative.

For Topping
• Chopped Reese’s / Mini Chocolate Chips – Enhances flavor and texture; customize with other chocolates or candies as desired.

How to Make Peanut Butter Cake

Preheat Oven: Start by preheating your oven to 350°F (175°C). Greasing and flouring your cake pans will ensure the cakes release easily once baked.
Mix Dry Ingredients: In a bowl, whisk together the all-purpose flour, baking powder, and kosher salt. This step helps evenly distribute the leavening agent for a good rise.
Cream Butter and Sugars: In a separate bowl, beat the softened butter, brown sugar, and granulated sugar together until light and fluffy—about 3-5 minutes. This process adds aeration to your batter.
Incorporate Wet Ingredients: Add the creamy peanut butter, sour cream, vanilla extract, eggs, and milk to the butter mixture. Beat everything until it’s smooth and well combined, creating that luscious base we all love.
Combine Mixtures: Gradually mix the dry ingredients into the wet mixture, being careful not to overmix. Stir just until combined for a light texture.
Bake: Divide the batter evenly between the prepared pans and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Look for a light golden color.
Cool: Allow the cakes to cool in the pans for 10 minutes. Then, carefully transfer them to wire racks to cool completely—this step is crucial for proper frosting application!
Make Frosting: In a mixing bowl, beat the softened cream cheese and butter until creamy. Gradually add powdered sugar and vanilla, then mix in heavy cream. Beat until fluffy and smooth, making the frosting as delightful as the cake!
Frost Cakes: Once the cakes are cool, frost generously between the layers and on top and sides. Drizzle melted peanut butter over the top, then sprinkle with chopped Reese’s or mini chocolate chips for an extra indulgent finish.

Optional: For added richness, top with crushed nuts for a delightful crunch!

Storage Tips for Peanut Butter Cake

Fridge: Keep the Peanut Butter Cake covered in an airtight container in the fridge for up to 5 days to maintain freshness and moisture.
Freezer: For longer storage, wrap slices tightly in plastic wrap and foil; they can be frozen for up to 3 months, ensuring you have a delightful treat anytime!
Reheating: To enjoy the cake warm, microwave slices for about 10-15 seconds. Be careful not to overheat to prevent drying it out.
Tip: If storing frosted cake, let it set in the fridge for about an hour before wrapping to prevent the frosting from sticking to the plastic wrap.

Expert Tips for Peanut Butter Cake

• Room Temperature Ingredients: Ensure all ingredients are at room temperature for better blending and a smoother batter.

• Avoid Overmixing: Mix the batter gently after adding flour to keep your Peanut Butter Cake light and airy—overmixing can lead to a dense texture.

• Egg Beating: Beat the eggs until pale yellow to help achieve the perfect rise in your cake. This step is crucial for an airy crumb.

• Proper Cooling: Allow cakes to cool completely before frosting; this prevents the frosting from melting and ensures an appealing presentation.

• Frosting Technique: For an extra fluffy frosting, beat in heavy cream at the end—this creates a decadent topping that complements the cake perfectly.

Peanut Butter Cake Recipe FAQs

What type of peanut butter should I use for the cake?
Absolutely! For this Peanut Butter Cake, I recommend using creamy peanut butter to achieve a smooth texture. However, if you enjoy a bit of crunch, feel free to swap in crunchy peanut butter for an added bite. Just ensure it’s a quality brand for the best flavor.

How should I store leftovers of the Peanut Butter Cake?
To maintain the cake’s freshness, store it in an airtight container in the fridge for up to 5 days. This keeps the moisture intact and prevents it from drying out. I often line my container with wax paper for extra protection.

Can I freeze the Peanut Butter Cake?
Yes, you can freeze the Peanut Butter Cake! Wrap any slices tightly in plastic wrap followed by aluminum foil to protect them from freezer burn. They will stay delicious for up to 3 months. When you’re ready to enjoy, simply remove from the freezer and let it thaw in the fridge overnight for an effortless treat!

What can I do if my cake doesn’t rise?
Very good question! If your cake doesn’t rise as expected, check if your baking powder is fresh—old baking powder can lead to flat cakes. Also, ensure you’ve beaten your eggs until they’re pale yellow, as this helps trap air for leavening. Lastly, avoid overmixing when you combine wet and dry ingredients to keep it light and fluffy!

Is this Peanut Butter Cake suitable for people with nut allergies?
This Peanut Butter Cake contains peanuts, so it’s not suitable for those with nut allergies. However, you can easily adapt the recipe! Try using sunflower seed butter or a similar nut-free alternative to create a delicious version that’s safe for everyone.

How should I wrap the Peanut Butter Cake for long-term storage?
For long-term storage, wrap each slice of the Peanut Butter Cake tightly in plastic wrap to seal in freshness, then wrap again with aluminum foil to prevent freezer burn. This way, you can enjoy a delicious slice anytime without losing its lovely moistness. Just remember to label with the date for easy reference!
