• Mixing bowls (large and medium)
• Whisk and spoon
• Measuring cups and spoons
• Spatula
• Small saucepan (for glaze) or microwave-safe bowl
• Cooling rack

Ingredients

For the Cake:

• 1¾ cups (220g) all-purpose flour
• ⅓ cup (80g) peanut butter
• 1 teaspoon baking soda
• ½ teaspoon salt
• 1 cup (200g) brown sugar
• 1 large egg, beaten
• 1 cup (240ml) buttermilk
• ½ teaspoon vanilla extract

For the Glaze:

• 1 tablespoon peanut butter
• ½ tablespoon icing sugar
• 5 tablespoons milk

Instructions

1. Preheat and prepare the pan

Set your oven to 350°F (175°C). Lightly grease a loaf pan with butter or line it with parchment paper so the cake won’t stick.

2. Mix the dry ingredients

In a large bowl, sift together the all-purpose flour, baking soda, and salt. Set this mixture aside for now.

3. Combine the wet ingredients

In another bowl, beat the brown sugar and peanut butter until smooth and creamy. Add the beaten egg, buttermilk, and vanilla extract, stirring until everything is fully combined.

4. Bring wet and dry together

Gradually fold the dry ingredients into the wet mixture using a spatula. Mix just until combined don’t overdo it, or the cake might become dense.

5. Bake the cake

Pour the batter into the prepared loaf pan and smooth the top. Bake in the oven for 45–50 minutes. The cake is done when a toothpick inserted into the center comes out clean.

6. Prepare the glaze

While the cake is baking, make the glaze. In a small saucepan over low heat, stir together peanut butter, icing sugar, and milk until smooth and slightly thickened. You can also do this in the microwave in short bursts, stirring in between.

7. Glaze and serve

When the cake comes out of the oven, let it cool in the pan for 10 minutes. Then transfer it to a wire rack. Drizzle the peanut butter glaze over the warm cake and let it set slightly before slicing and serving.

Expert Tips

1. Use room temperature egg, buttermilk, and peanut butter to ensure smooth mixing and even baking. Cold ingredients can create lumps and affect texture.

2. Gently fold the dry ingredients into the wet mixture. Over mixing develops gluten, which can make the cake dense instead of soft and tender.

3. Grease the loaf pan well or line it with parchment paper to prevent sticking and ensure the cake releases easily after baking.

4. Start checking the cake around 40 minutes by inserting a toothpick. Remove immediately when it comes out clean to avoid a dry loaf.

5. Apply the peanut butter glaze while the cake is slightly warm. This allows it to soak in lightly, enhancing flavor without making the top soggy.

Additions And Variations

➤ Chocolate Chips: Fold in ½ cup of semi-sweet or milk chocolate chips to add bursts of chocolate richness in every slice.

➤ Chopped Peanuts: Sprinkle ¼ cup of roasted or salted peanuts into the batter or on top before baking for added crunch and texture.

➤ Banana: Mash one ripe banana and mix it into the wet ingredients to enhance moisture and add natural sweetness with a subtle fruity flavor.

➤ Cocoa Swirl: Mix 2 tablespoons of cocoa powder with a little milk and swirl it into the batter before baking for a marbled chocolate-peanut butter effect.

➤ Honey or Maple Drizzle: Replace or complement the glaze with a drizzle of honey or maple syrup after baking for a different layer of sweetness and flavor.
