In your saucepan, combine the [dark sweet cherries], [granulated sugar], and a splash of water. Let them bubble softly for about 5 minutes. My little Olivia loves to watch the juices turn a deep, beautiful ruby red, it’s like liquid jewels!
Stir in your [cornstarch] slurry and cook until it’s thick and glossy. Remove from heat and add the [Kirsch or Cherry Juice]. Let this cool completely; we don't want to melt our cream later!
Preheat your oven to 350°F. Beat the [eggs] (yolks only!) with ½ cup of [granulated sugar] until they are thick and pale. I tell Olivia this is the "ribbon stage" because the batter should fall back into the bowl like a silk ribbon.
In a clean bowl, beat the [eggs] (whites) with [salt] until they stand up in stiff, glossy peaks. Olivia’s Tip: Make sure your bowl is super clean! Even a drop of yolk will stop the magic from happening.
Gently fold your sifted [unsweetened cocoa powder] and [all-purpose flour] into the yolks. Then, fold in those fluffy whites very carefully so we don't lose the air. This is the secret to a cake that doesn't crack!
Pour into your lined pan and bake for 12-15 minutes. It should spring back when touched.
While the cake is hot, flip it onto a towel dusted with powdered sugar. Remove the parchment and roll the cake up with the towel. This "muscle memory" helps the cake stay together later. Olivia calls this the "cake sleeping bag." Let it cool for 45 minutes
Whip the cold [heavy whipping cream], [cream cheese], [granulated sugar], and [vanilla extract]. The cream cheese is my secret to making sure the cake stays perfect even if it sits in the fridge overnight!
Unroll your cool cake. Spread the cream and then the cherries. Roll it back up tightly. It might crack a little, but don't worry, momma’s ganache covers everything! Wrap in plastic and chill for 2 hours.
Melt [semi-sweet chocolate chips] with [heavy cream] until glossy. Pour over your chilled roll and top with fresh cherries. It looks so fancy, but we know how easy it really was!
