How to Make Chocolate Cream Puffs with Chocolate Mousse

Step 1: Preheat and Prep

Preheat oven to 400°F (204°C). Line a baking sheet with parchment paper.

Step 2: Make the Chocolate Pastry Dough

In a saucepan, combine water, butter, sugar, and salt. Bring to a boil.

Remove from heat and stir in flour and cocoa powder until smooth.

Return to heat, stirring constantly until a thin film forms on the pan.

Step 3: Add the Eggs

Transfer dough to a mixing bowl. Beat briefly to cool slightly.

Add eggs one at a time, mixing until fully incorporated.

Dough should be smooth and pipeable.

Step 4: Pipe and Bake

Transfer dough to a piping bag fitted with a round tip.

Pipe 1.5-inch mounds onto the prepared baking sheet, spacing 1-2 inches apart.

Bake for 18–20 minutes until puffed and set.

Cool completely on a wire rack.

Step 5: Make the Chocolate Mousse

In a large bowl, beat heavy cream, cocoa powder, powdered sugar, granulated sugar, and vanilla extract until stiff peaks form.

Be careful not to overwhip.

Step 6: Fill the Cream Puffs

Slice puffs in half or poke a hole in the side.

Fill with chocolate mousse using a piping bag.

Step 7: Finish

Dust with powdered sugar or drizzle with chocolate glaze if desired.

Serve immediately or refrigerate.
