📝 Ingredients

For the Chocolate Sponge Cake:

• 4 large eggs, room temperature

• ¾ cup (150g) granulated sugar

• ¼ cup (60ml) milk (or buttermilk)

• 1 tsp vanilla extract

• ¾ cup (95g) all-purpose flour

• ¼ cup (25g) cocoa powder (Dutch-processed for richer flavor)

• 1 tsp baking powder

• ¼ tsp salt

For the Peanut Butter Filling:

• 1 cup (250g) creamy peanut butter (not natural/oily)

• ½ cup (113g) unsalted butter, softened

• 1 ½ cups (180g) powdered sugar

• 1 tsp vanilla extract

• 2-3 tbsp heavy cream (as needed for consistency)

For the Ganache Drizzle (Optional):

• ½ cup (90g) chocolate chips

• ¼ cup (60ml) heavy cream

🍳 Instructions

1. Bake the Chocolate Sponge Cake

• Preheat oven to 350°F (175°C). Line a 10×15-inch jelly roll pan with parchment paper.

• Whip eggs + sugar on high speed for 5-7 mins until pale and thick (ribbon stage).

• Gently fold in milk + vanilla.

• Sift in flour, cocoa powder, baking powder, salt; fold until just combined.

• Pour into pan, spread evenly. Bake 12-15 mins until springy to touch.

2. Roll the Cake (Hot!)*

• Right out of the oven, dust the top with powdered sugar.

• Place a clean kitchen towel over the cake, then flip it onto a flat surface.

• Peel off parchment, then roll cake + towel tightly from the short end. Cool completely.

3. Make the Peanut Butter Filling

• Beat peanut butter + butter until smooth.

• Gradually add powdered sugar + vanilla, then cream until fluffy.

4. Assemble

• Unroll the cooled cake, spread filling evenly, leaving a ½-inch border.

• Re-roll gently (no towel this time!). Chill 30 mins to set.

5. Optional Ganache

• Heat cream until steaming, pour over chocolate chips, let sit 2 mins, then stir until smooth. Drizzle over cake.

🌟 Pro Tips

✔ Room temp eggs are key for maximum volume in the sponge.
✔ Roll while warm to prevent cracks. If it cracks, cover with ganache!
✔ Extra Reese’s vibe? Press chopped peanut butter cups into the filling before rolling.
