Step-by-Step Instructions
-
Step 1: Prepare Your Pan and Oven
Preheat your oven to 375°F (190°C). Line a 10×15-inch (or similar size) jelly roll pan with parchment paper, allowing some overhang on the sides. Lightly grease the parchment paper for easy release. This step is crucial for preventing your cake from sticking.
Small tip: Make sure the parchment paper overhangs the sides; it will act as “handles” to lift the cake later.
-
Step 2: Whisk Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, cocoa powder, baking powder, baking soda, and salt. Make sure there are no lumps, especially in the cocoa powder. This ensures even distribution of the leavening agents.
-
Step 3: Combine Wet Ingredients (Except Hot Liquid)
In a large bowl, using an electric mixer, beat the granulated sugar and eggs on medium-high speed for about 3-5 minutes, until the mixture is pale yellow and thick. Beat in the vanilla extract, milk, and vegetable oil until just combined. Don’t overmix at this stage.
-
Step 4: Mix Batter and Add Hot Liquid
Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed until just combined. Scrape down the sides of the bowl as needed. Then, slowly pour in the hot water or coffee, mixing until the batter is smooth. The batter will be thin, and that’s perfectly normal for a roll cake.
Small tip: Hot liquid helps to “bloom” the cocoa powder, enhancing the chocolate flavor significantly.
-
Step 5: Bake the Cake
Pour the thin batter evenly into your prepared jelly roll pan. Spread it gently to cover the entire surface. Bake for 12-15 minutes, or until a wooden skewer inserted into the center comes out clean. The cake will spring back when lightly touched.
-
Step 6: Prepare for Rolling
While the cake bakes, lay a clean kitchen towel on your counter and dust it generously with powdered sugar. As soon as the cake comes out of the oven, immediately invert it onto the sugared towel. Carefully peel off the parchment paper. Trim any crisp edges of the cake if desired.
Small tip: Dusting the towel with powdered sugar prevents the cake from sticking and adds a little sweetness.
-
Step 7: Roll and Cool the Cake
Starting from one short end, carefully roll the warm cake and the towel together into a tight log. Place the rolled cake, seam-side down, on a wire rack and let it cool completely to room temperature, about 1 hour. This “trains” the cake to hold its rolled shape without cracking.
-
Step 8: Make the Peanut Butter Filling
While the cake cools, prepare the filling. In a large bowl, beat the softened cream cheese and butter with an electric mixer until light and fluffy. Add the creamy peanut butter and beat until well combined. Gradually add the sifted powdered sugar, one cup at a time, beating until smooth. Stir in the vanilla extract. If the filling is too thick, add milk or cream one tablespoon at a time until it’s spreadable.
Small tip: Sifting powdered sugar prevents lumps, making your frosting silky smooth.
-
Step 9: Fill and Re-Roll the Cake
Once the cake is completely cool, gently unroll it. Spread the peanut butter filling evenly over the entire surface of the cake, leaving about a ½-inch border along one of the short ends. Carefully re-roll the cake, without the towel this time, into a tight log. Place it seam-side down on a serving platter.
-
Step 10: Chill the Cake
Cover the roll cake loosely with plastic wrap and refrigerate for at least 1 hour. This chilling time helps the filling set and makes the cake easier to slice cleanly.
-
Step 11: Prepare the Ganache and Finish
To make the ganache, heat the heavy cream in a small saucepan over medium heat until it just begins to simmer. Remove from heat and pour over the chocolate chips in a heatproof bowl. Let it sit for 5 minutes, then whisk until smooth and glossy. Let the ganache cool slightly until it’s thick enough to spread but still pourable.
-
Step 12: Frost and Garnish
Pour or spread the slightly cooled ganache over the chilled roll cake, allowing it to drip down the sides. Garnish immediately with chopped mini peanut butter cups and roasted peanuts, if using. Slice with a sharp, warm knife and serve!
Tips & Variations
- Gluten-Free Option: Replace all-purpose flour with a 1:1 gluten-free baking flour blend (that contains xanthan gum). Ensure all other ingredients are certified gluten-free.
- Vegetarian Option: This recipe is naturally vegetarian. For a healthier filling, you could try a Greek yogurt-based peanut butter frosting, though it will be tangier and less stable.
- Add More Protein: Stir 2-3 tablespoons of unflavored or vanilla protein powder into the peanut butter filling for an extra protein boost. You might need an extra splash of milk to maintain the desired consistency.
- Flavor Boosts: Instead of hot water, use hot brewed coffee to deepen the chocolate flavor. For a hint of spice, you could add a tiny pinch of cayenne pepper to the ganache (though this is less common for this specific cake profile).
- Nut-Free Option: If you have nut allergies, swap the peanut butter for an equal amount of sunflower seed butter (SunButter) and omit the peanut garnish. The flavor profile will change, but it will still be delicious!
- Different Frosting: If you’re not a fan of peanut butter, you can fill this chocolate roll cake with a simple cream cheese frosting, raspberry jam, or even whipped cream and fresh berries.

Health Benefits
While this is a dessert, some of its key ingredients offer surprising health perks!
- Dark Chocolate/Cocoa Powder: Cocoa powder, especially unsweetened varieties, is packed with antioxidants called flavonoids. These compounds can help reduce inflammation and may improve heart health by lowering blood pressure and improving blood flow. It also contains minerals like iron, magnesium, and copper.
- Peanut Butter: Creamy peanut butter is a good source of plant-based protein, which is essential for muscle repair and growth. It also provides healthy monounsaturated and polyunsaturated fats, which can help lower bad cholesterol levels. Peanuts contain vitamins like E and B3 (niacin), and minerals such as magnesium and phosphorus.
- Eggs: Eggs are a powerhouse of nutrition, offering high-quality protein and all nine essential amino acids. They are also a good source of vitamins D, B6, B12, and minerals like selenium and zinc. Choline, present in egg yolks, is important for brain health and metabolism.
- Milk: Milk contributes calcium and vitamin D,
