Peanut cake may not be as commonly found as chocolate or vanilla, but it deserves just as much love. With its rich, nutty flavor and moist, tender crumb, this cake offers a delicious twist on traditional homemade desserts. Whether you’re a peanut lover or just looking to try something different, this guide will show you how to make a peanut cake that’s both unique and easy to bake at home.
Why Choose Peanut Cake?
Peanuts are naturally rich in flavor and pair beautifully with both sweet and savory elements. When used in baking, they create a depth of flavor that’s nutty, slightly roasted, and incredibly satisfying. A peanut cake stands out because:
- It has a distinctive taste
- It’s packed with protein and natural oils
- It’s easy to customize (with chocolate, caramel, or spices)
- It makes a perfect snack, dessert, or even a breakfast cake
Key Ingredients for a Flavorful Peanut Cake
Here’s what you’ll need for a basic peanut cake recipe that strikes a balance between simplicity and taste:
- 1 ½ cups (200g) all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- ¾ cup (180g) smooth peanut butter
- ½ cup (115g) unsalted butter (softened)
- 1 cup (200g) brown sugar (light or dark)
- 2 large eggs (room temperature)
- 1 teaspoon vanilla extract
- ½ cup (120ml) milk
- ½ cup (120ml) plain yogurt or sour cream
Optional add-ins:
- ¼ cup chopped peanuts (for crunch)
- Chocolate chips or swirls of jam
- A dash of cinnamon for warmth
Step-by-Step: How to Make Peanut Cake
1. Preheat and Prepare
Start by preheating your oven to 350°F (180°C). Grease and flour a 9-inch round or square cake pan.
2. Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
3. Cream the Butters and Sugar
In a large mixing bowl, beat the peanut butter and butter together until creamy and smooth (about 2–3 minutes). Add the brown sugar and beat again until fluffy.
4. Add the Eggs and Vanilla
Beat in the eggs one at a time, mixing well after each addition. Add the vanilla extract.
5. Alternate Dry and Wet
Mix the milk and yogurt in a small bowl. Add the dry ingredients to the butter mixture in three parts, alternating with the milk mixture. Begin and end with the dry ingredients. Mix until just combined — don’t overmix.
6. Bake
Pour the batter into the prepared pan and smooth the top. Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
7. Cool and Serve
Let the cake cool in the pan for 10 minutes before transferring to a wire rack. Allow to cool completely before frosting (if using) or slicing.
Optional Frosting and Toppings
While this cake is delicious on its own, you can elevate it with one of these simple finishes:
Peanut Butter Frosting
- ½ cup (120g) peanut butter
- ¼ cup (60g) butter
- 1 ½ cups (180g) powdered sugar
- 2 tablespoons milk
- ½ teaspoon vanilla extract
Whip all ingredients together until smooth and spreadable.
Chocolate Ganache
- ½ cup (120ml) cream
- 100g dark or milk chocolate
- 1 tablespoon butter
Heat cream until just boiling, pour over chopped chocolate, and stir in butter until glossy.
Honey Drizzle or Maple Glaze
Just a light drizzle of honey or maple syrup can balance the richness and add sweetness without overpowering.
Storage Tips
Peanut cake stores well and actually becomes more flavorful after a day or two.
- Room temperature: Store in an airtight container for up to 3 days.
- Refrigerator: Store for up to 5 days if frosted. Bring to room temperature before serving.
- Freezer: Wrap slices individually and freeze for up to 2 months.
Tips for Success
- Use creamy peanut butter: Avoid natural peanut butter for this recipe, as the texture and separation can affect the result.
- Don’t overmix: Stop mixing as soon as the ingredients are combined to keep the cake tender.
- Balance the salt: A touch of salt enhances the nuttiness, but too much can overpower it.
- Layered version? Double the recipe and turn it into a frosted celebration cake.
Peanut Cake Pairings
Wondering what to serve with this nutty delight? Here are some pairing ideas:
- Coffee or espresso – the bitterness complements the richness.
- Vanilla ice cream – for a warm and cold contrast.
- Berry jam – spread on top for a PB&J twist.
- Caramel sauce – drizzle over a warm slice for ultimate comfort.
When to Serve Peanut Cake

- Cozy family dinners
- Weekend breakfast treats
- Bake sales or potlucks
- Kids’ lunchbox snacks
- Birthday parties for peanut butter lovers
