STEP-BY-STEP INSTRUCTIONS
Step 1: Prepare the Cake
Preheat your oven to 350°F (175°C). Grease and line a 9-inch round cake pan with parchment paper.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
Step 3: Cream Butter and Peanut Butter
In a large mixing bowl, beat the softened butter, peanut butter, and sugar until light and fluffy, about 3–4 minutes.
Step 4: Add Eggs
Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
Step 5: Combine
Gradually add the dry ingredients to the wet ingredients, alternating with the milk. Mix just until combined. Do not overmix.
Step 6: Bake
Pour the batter into the prepared cake pan and smooth the top. Bake for 40–50 minutes, or until a toothpick inserted into the center comes out clean.
Step 7: Cool
Allow the cake to cool in the pan for 15 minutes before transferring it to a wire rack to cool completely.
Step 8: Make the Glaze
In a saucepan over low heat, melt the butter and peanut butter together until smooth. Remove from heat and whisk in the powdered sugar, vanilla, salt, and heavy cream until thick but pourable.
Step 9: Decorate
Pour the glaze over the cooled cake, allowing it to drip naturally down the sides. Immediately sprinkle with roasted peanuts, crushed peanut butter cookies, crunchy cereal, and peanut butter chips if using. Finish with generous spoonfuls of creamy peanut butter on top.
Step 10: Serve
Let the glaze set for about 20 minutes before slicing. Enjoy with a glass of milk or a hot cup of coffee.
TIPS
- Toast the peanuts lightly for an even richer flavor.
- Chill the cake for 20–30 minutes before slicing for cleaner cuts.
- Use natural peanut butter only if it’s well stirred.
- Store leftovers in an airtight container at room temperature for 2 days or refrigerate for up to 5 days.
NOTES
This cake is very rich, making it perfect for serving at parties or special occasions. For extra indulgence, drizzle warm caramel sauce over each slice before serving.
