So many people love chocolate and Oreos they will love this cake roll, it's rich and creamy.
FOR THE CAKE
3 large eggs
3/4 cup granulated sugar
2 teaspoons brewed coffee -I used decaf because children will be eating mine(or milk, or water)
1 teaspoon vanilla extract
1/4 cup unsweetened dark cocoa powder
1/4 teaspoon salt
1 teaspoon baking powder
3/4 cup all purpose flour
Powdered sugar, to aid in rolling
FOR THE FILLING:
3/4 cups heavy whipping cream
1 tablespoon powdered sugar
1 teaspoon vanilla extract
12 Oreos- crushed
FOR THE TOPPING (OPTIONAL):
1/2 cup heavy whipping cream
1 cup chocolate chips
Make the Cake: preheat oven to 350°F. Line a jelly roll (10x15”) pan with parchment and spray with cooking spray (I like to use the spray with flour).
Beat eggs at high speed for 3 minutes, until frothy and dark yellow. Beat in sugar, coffee or water, and vanilla extract.
Whisk together cocoa, salt, baking powder, and flour. Stir into wet ingredients just until blended.
Spread in prepared pan. Batter will be in a very thin layer and you will need to use a wooden spoon or spatula to spread it to all the corners of the pan. Bake for 10-15 minutes. You’ll know it’s done because if you lightly poke the top with your fingertip it will slightly bounce back. Watch carefully this thin cake won't take long.
While the cake is baking, set a clean kitchen towel out on a large work surface. Sprinkle liberally with powdered sugar (about 1/4 cup). As soon as the cake comes out of the oven, turn it over on the kitchen towel sprinkled with powdered sugar. Remove parchment carefully.
Working at the short end, fold the edge of the towel over the cake. Roll tightly, rolling up the cake into the towel. Let cool completely while rolled, at least one hour but not much longer.
Make the Filling: beat heavy whipping cream in an electric mixer fitted with the whisk attachment. (You can also use a hand mixer, but it will take longer, be sure bowl is grease free when whipping cream) Slowly add in powdered sugar and vanilla during beating. Beat until whipped peaks form. Gently stir in crushed Oreos, reserving a tablespoon or two for garnish.
Assemble Cake: once the cake has cooled, unroll it slowly gently. Spread the whipped cream on the cake, leaving 1” without filling at either end. Re-roll cake, scooping out any filling that spills out as you roll. Cover with plastic wrap and chill for at least one hour before frosting. If you have leftover whipped cream, you can use it for serving.
Make the topping: place chocolate chips and heavy whipping cream in a microwave safe measuring cup or bowl. Heat on high power for 60-90 seconds or until the cream is hot, then whisk until smooth. Let cool for 10 minutes.
Place cake roll on a wire rack set over a cookie sheet. Pour the ganache over the cake evenly. Top with remaining crushed cookies. Chill until set.
Note: The cake should stay chilled until right before serving.
