How to Make Peanut Butter Cake
-
Preheat the oven to 350°F (175°C) and prepare your baking pans by spraying them with cooking spray to prevent sticking.
-
Mix the dry ingredients by combining the all-purpose flour, baking powder, and kosher salt in a mixing bowl. Set this aside for later use.
-
Cream together the softened butter, packed brown sugar, and granulated sugar in a separate bowl until the mixture is light and fluffy. This will take about 2-3 minutes.
-
Add in the peanut butter, sour cream, and vanilla extract. Gradually mix in the eggs, one at a time, followed by the milk. Make sure everything is well combined.
-
Fold the dry ingredients into the wet mixture, stirring until just combined. Be careful not to overmix; a few flour streaks are okay!
-
Pour the batter into the prepared pans and smooth the top with a spatula. Bake for approximately 25-30 minutes, or until a toothpick inserted in the center comes out clean.
-
Cool the cakes in the pans for about 10 minutes, then gently turn them out onto wire racks to cool completely.
-
Prepare the frosting by mixing the softened cream cheese, remaining butter, peanut butter, and powdered sugar until smooth and creamy. Add a little heavy cream if the mixture is too thick.
-
Frost the cooled cake layers generously with the peanut butter frosting, and for the finishing touch, drizzle with melted peanut butter and sprinkle chopped Reese’s and mini chocolate chips on top.
Optional: For an extra touch, garnish with crushed nuts for a delightful crunch!

Storage Tips for Peanut Butter Cake
Room Temperature: Store leftovers in an airtight container at room temperature for up to 3 days to keep them moist and flavorful.
Fridge: For extended storage, refrigerate the cake in an airtight container for up to one week.

Expert Tips for Peanut Butter Cake
- Room Temperature Ingredients: Ensure butter, cream cheese, and eggs are at room temperature for better mixing, resulting in a smoother batter.
- Avoid Overmixing: Mixing just until combined keeps the cake light and fluffy. Overmixing can lead to a dense texture, which we want to avoid!
- Use Fresh Ingredients: Always check your baking powder for freshness. This ensures the best rise and texture in your Peanut Butter Cake.
- Frosting Consistency: If your frosting is too thick, a splash of heavy cream can help achieve the perfect spreadable consistency without losing flavor.
- Chill for Set Decor: Allow the cake to chill for about 30 minutes after frosting. This helps the decorations set, making it easier to slice and serve.

Peanut Butter Cake Recipe FAQs
How do I pick the right peanut butter?
Absolutely! When choosing peanut butter for this cake, look for natural varieties that contain just peanuts and salt for a cleaner taste. Avoid options with added sugars or oils, as they can alter the cake’s flavor and texture. If you’re trying to make it healthier, smooth natural peanut butter works best, but feel free to go for the crunchy type if you enjoy a bit of texture!
What’s the best way to store Peanut Butter Cake?
Very simple! Store your Peanut Butter Cake in an airtight container at room temperature for up to 3 days to maintain its freshness. If you’d like it to last longer, refrigerate it for up to a week. Just be sure to keep it wrapped so it doesn’t absorb any odors from your fridge.
Can I freeze Peanut Butter Cake?
Absolutely! To freeze your Peanut Butter Cake, first ensure it is completely cooled. Wrap individual slices or the whole cake tightly in plastic wrap, then place it in a freezer-safe bag or container. It will keep for up to 3 months. When ready to enjoy, simply thaw it overnight in the fridge and warm it in the microwave for 10-15 seconds before serving.
What should I do if my cake doesn’t rise?
If your Peanut Butter Cake doesn’t rise as expected, check the freshness of your baking powder first—it should be within its expiration date. Also, be careful not to overmix your batter, as this can weaken the cake structure and prevent it from rising. Finally, ensure you have the right oven temperature; using an oven thermometer can help accuracy as many home ovens have slight discrepancies.
Can this cake be made allergy-friendly?
Yes, it can! For a gluten-free option, substitute the all-purpose flour with a gluten-free flour blend. You can also make it dairy-free by using plant-based butter and milk alternatives. For those with egg allergies, flax eggs (1 tablespoon of ground flaxseed mixed with 3 tablespoons of water per egg) can successfully replace the eggs in this recipe without compromising flavor.
Is it safe to give Peanut Butter Cake to pets?
While peanut butter is generally safe for dogs in moderation, be cautious of added sugars and xylitol (a common sweetener), which is toxic to pets. It’s always best to consult with your veterinarian before sharing human food with your furry friends, even a delicious Peanut Butter Cake!
