We celebrated my older daughter’s birthday recently with a four-layer gluten-free chocolate cake with a chocolate ganache frosting and filling. I have to admit, it looked and tasted amazing.
I recently took a baking boot camp at Kendall College in Chicago, which gave me inspiration for creating this cake. In the class, we made an opera cake, but my daughter wanted chocolate, so I improvised from there. I started with my favorite King Arthur gluten-free chocolate cake mix. I don’t usually use mixes, but the King Arthur cake is so intensely moist and fudgy that it always elicits raves from kids and adults.
To make chocolate ganache, heat 1 1/2 cups heavy cream in a saucepan until the cream starts to steam. Then pour the cream over 10 ounces of semisweet or dark chocolate chips. Wait two minutes, then stir until smooth. Let cool to room temperature. Set aside some ganache for frosting the top of the cake. Whip the rest in a stand mixer to make whipped chocolate ganache for the filling.
To make the thin layers, I baked the cake for 15 to 18 minutes in a jelly roll pan or half-sheet pan (18 x 13 x 1-inch) lined with parchment paper. I then cut the cooled cake into four equal-sized rectangles, stacked the layers on top of each other while smoothing whipped chocolate ganache between the layers, and topped it with chocolate ganache that had not been whipped. For a distinctive presentation, freeze the cake for 30 minutes and then evenly trim the sides.
Now that’s a happy birthday!
