• 150 g (¾ cup) sugar
• 150 g (⅔ cup) butter, melted
• 3 large eggs
• 175 g (1 cup + 3 tablespoons) plain or all-purpose flour
• 1 teaspoon baking powder
• 1 teaspoon vanilla extract
• ½ teaspoon almond essence, optional
• 3 tablespoons plain yogurt
• 50 g (¼ cup) peanut butter
• Chocolate sprinkles, as desired

 

For the Peanut Butter Drip

• 100 g white chocolate
• 1–2 tablespoons milk
• 2 tablespoons peanut butter

Measuring cup size: 240 ml
Baking pan: 21 × 11 × 6 cm (2 lb loaf pan)
Oven temperature: 170°C (338°F)
Baking time: 45–55 minutes

How to Make Peanut Butter Cake

 

Step 1: Prepare the Oven and Pan

Preheat your oven to 170°C (338°F).

Lightly grease a 21 × 11 × 6 cm loaf pan and line it with baking paper.

Leaving a little extra baking paper above the sides of the pan will make it easier to lift the finished cake out after baking.

Set the prepared pan aside.

Step 2: Combine the Sugar and Melted Butter

Place 150 g sugar in a large mixing bowl.

Pour in 150 g melted butter.

Whisk until the butter and sugar are thoroughly combined.

Make sure the melted butter isn’t extremely hot before you begin adding the remaining ingredients.

Step 3: Add the Eggs

Add the 3 eggs, preferably one at a time, mixing well after each addition.

Continue whisking until the mixture looks smooth and evenly combined.

Room-temperature eggs are useful here because they incorporate more easily into the butter mixture.

 

Step 4: Add the Flavorings

Pour in 1 teaspoon vanilla extract.

If you enjoy the flavor, add ½ teaspoon almond essence as well.

The almond essence is completely optional. Vanilla alone works beautifully with peanut butter and chocolate.

Mix briefly to combine.

Step 5: Add the Yogurt

Add 3 tablespoons plain yogurt.

Whisk until incorporated.

Yogurt provides additional moisture and helps create a softer, more tender crumb.

For best results, use plain unsweetened yogurt rather than a flavored variety.

Step 6: Add the Peanut Butter

Add 50 g (¼ cup) peanut butter to the mixture.

Stir or whisk until the peanut butter is evenly incorporated and the batter has a uniform consistency.

Smooth peanut butter is especially easy to incorporate, although the type you use can also influence the final texture.

 

Add the Dry Ingredients

Step 7: Combine Flour and Baking Powder

In a separate bowl, combine:

• 175 g plain or all-purpose flour
• 1 teaspoon baking powder

Sifting the ingredients is optional, but it can help remove lumps and distribute the baking powder evenly.

Step 8: Mix the Batter

Gradually add the dry ingredients to the wet mixture.

Using a spatula, gently fold everything together until no visible pockets of flour remain.

Avoid overmixing once the flour has been added.

Mixing excessively can develop too much gluten and make the finished cake heavier instead of soft and tender.

 

Step 9: Add Chocolate Sprinkles

Add chocolate sprinkles according to your preference.

Gently fold them through the batter until they’re reasonably evenly distributed.

You can reserve a small amount to scatter over the top if you’d like.

Chocolate and peanut butter are a classic combination, so even a small amount of chocolate gives this simple loaf extra flavor.

Transfer the Batter to the Pan

Spoon the prepared batter into your lined loaf pan.

Use a spatula or the back of a spoon to spread it evenly into the corners and gently smooth the surface.

If desired, scatter a few additional chocolate sprinkles over the top.

 

Bake the Peanut Butter Cake

Place the loaf pan in the preheated oven.

Bake at 170°C (338°F) for approximately 45–55 minutes.

Since ovens can vary, begin checking the cake around the 45-minute mark.

Insert a toothpick or thin wooden skewer into the center. If it comes out clean or with only a few moist crumbs, the cake is ready.

If you see wet batter, return it to the oven and continue baking for a few more minutes.

If the top is becoming too dark before the center is cooked, loosely cover it with aluminum foil for the remaining baking time.

Cool the Cake

Remove the loaf from the oven and leave it in the pan for approximately 10–15 minutes.

Carefully transfer it to a cooling rack and allow it to cool completely.

This is particularly important if you’re adding the peanut butter drip.

If the cake is still warm, the topping can become too thin and run straight off instead of creating a beautiful coating.

 

How to Make the White Chocolate Peanut Butter Drip

The topping is one of the easiest ways to turn this everyday loaf into a more impressive dessert.

You only need three ingredients.

Step 1: Melt the White Chocolate

Place 100 g white chocolate in a microwave-safe bowl.

Melt it gently in short intervals, stirring between each one.

Alternatively, melt the chocolate using a heatproof bowl placed over a saucepan of gently simmering water.

Avoid overheating white chocolate because it can become thick or grainy.

 

Step 2: Add the Peanut Butter

Add 2 tablespoons peanut butter to the melted white chocolate.

Stir until the mixture becomes smooth and evenly combined.

Step 3: Adjust with Milk

Add 1 tablespoon milk and stir.

If the mixture is still too thick for drizzling, gradually add a little more milk, up to approximately 2 tablespoons total.

Add the milk slowly. It’s much easier to thin the mixture gradually than to fix a topping that has become too runny.

You want a smooth consistency that can slowly drip down the sides of the cake.

 

Decorate the Peanut Butter Cake

Make sure the cake has cooled completely.

Spoon the white chocolate peanut butter mixture over the top.

Gently encourage some of the topping toward the edges so that it naturally drips down the sides.

For an extra finishing touch, scatter additional chocolate sprinkles over the topping before it sets.

Allow the drip to settle slightly before slicing.

Why Yogurt Works So Well in Peanut Butter Cake

Peanut butter has a naturally thick consistency, so adding a little yogurt helps balance the cake batter.

The yogurt contributes moisture and tenderness without making the cake overly sweet.

It also helps create a softer crumb that complements the richness of the butter and peanut butter.

 

Tips for the Best Peanut Butter Cake

Let the melted butter cool slightly. You don’t want very hot butter coming into contact with the eggs.

Use room-temperature ingredients when possible. They combine more smoothly and help create an even batter.

Use plain yogurt. Sweetened or strongly flavored yogurt can change the intended flavor of the cake.

Mix the peanut butter thoroughly. Make sure there aren’t large unmixed pockets remaining in the batter.

Don’t overmix the flour. Fold only until everything is combined.

Check the cake at 45 minutes. Your oven may bake faster than another oven.

Cool completely before decorating. A warm cake will melt and thin the white chocolate topping.

Add milk gradually to the drip. Start with one tablespoon and only add more if necessary.

What Type of Peanut Butter Should I Use?

Smooth peanut butter is an easy choice because it blends evenly into both the cake batter and topping.

If you’re using natural peanut butter that separates into oil and solids, stir it extremely well before measuring.

The consistency of peanut butter varies considerably between brands, so the finished batter and drip may also vary slightly.

 

Can I Leave Out the Almond Essence?

Yes.

The ½ teaspoon almond essence is completely optional.

If you don’t have it or don’t enjoy almond flavor, simply leave it out.

Vanilla extract provides plenty of aroma on its own.

Can I Make the Cake Without Chocolate Sprinkles?

Absolutely.

Chocolate sprinkles are an optional addition and don’t affect the basic structure of the cake.

You can leave them out for a simple peanut butter loaf.

Alternatively, you could use a small amount of chocolate chips or finely chopped chocolate if you prefer more noticeable pieces of chocolate.

 

Can I Skip the Peanut Butter Drip?

Yes.

The cake can be served completely plain and will still have plenty of peanut butter flavor.

For a simpler finish, you can dust the cooled loaf lightly with powdered sugar.

The white chocolate peanut butter drip is mainly for additional flavor and decoration.

Why Is My Peanut Butter Cake Dry?

Overbaking is one of the most common causes of dry loaf cakes.

Begin testing at around 45 minutes rather than automatically baking for the full 55 minutes.

Too much flour can also produce a dry cake, so measure carefully.

Finally, avoid excessive mixing after adding the flour.

 

Why Did My Cake Sink in the Middle?

Opening the oven too early can cause the center of a cake to fall before its structure has set.

An underbaked center may also sink after the cake is removed from the oven.

Try not to open the oven unnecessarily during the early part of baking, and check the center with a skewer before removing the loaf.

How to Serve Peanut Butter Cake

This cake is rich enough to serve on its own, especially with the white chocolate peanut butter topping.

It’s delicious alongside:

• Hot coffee
• Black tea
• Cold milk
• Hot chocolate
• Fresh berries
• Vanilla ice cream

For dessert, serve a slice with a scoop of vanilla ice cream for a delicious combination of warm peanut butter flavors and creamy sweetness.

 

How to Store Peanut Butter Cake

Allow the cake and topping to set completely before storing.

Place the loaf in an airtight container to keep it from drying out.

If you’ve added the milk-containing white chocolate peanut butter drip, refrigeration is the best option for longer storage.

For the nicest texture, allow a refrigerated slice to sit at room temperature briefly before serving.

Can I Make This Cake Ahead of Time?

Yes.

You can bake the loaf ahead of time and decorate it later.

Allow the baked cake to cool completely, wrap it well and store it until you’re ready to serve.

For the freshest-looking finish, prepare and add the peanut butter drip closer to serving time.

This approach is especially convenient when making the cake for a party or family gathering.
