Step 1

Preheat the oven to 320 °F (160°C). Line the bottom and the sides of a 9-inch (23cm) springform pan with parchment paper and set aside. To line a springform pan with parchment paper, the easiest way is to cut out a circle for the bottom and strips for the sides.

Step 2

In a large mixing bowl with an electric mixer with a whisk attachment, mix the eggs, sugar, butter, and vanilla for about 3 minutes until creamy.

Step 3

Sift in the flour, cocoa, baking powder, and salt and mix just until well combined, about 1 minute. Pour the cake batter into the prepared baking pan and bake for about 30-35 minutes or until a toothpick inserted into the center comes out clean. Let it cool in the pan for 15 minutes, then remove from the pan and transfer to a cooling rack to cool completely.

Step 4

Place the drained sour cherries in a heatproof bowl and set aside.

Step 5

In a small bowl, stir together the cornstarch and 1/4 cup of the canned sour cherry water and set aside.

Step 6

In a heavy-bottomed saucepan, bring ¼ cup of the canned sour cherry water, kirsch, and sugar to a simmer over medium heat. Once it simmers, add the cornstarch mixture and cook for 1-2 minutes, stirring constantly, until it thickens like syrup and covers the back of a spoon. Remove from the heat and pour over the sour cherries. Let it cool completely.

Step 7

In a large mixing bowl with an electric mixer with a whisk attachment, beat the whipping cream on medium-high speed until soft peaks form, about 2-3 minutes. Then add the sugar and mix until stiff peaks form, about 1-2 minutes. Don't overmix or it will curdle.

Step 8

Cut the cake twice horizontally so that you have three cake layers.

Step 9

Place the bottom cake layer on a cake turner and brush it with cherry syrup. Spread with whipped cream and spread an additional ring of whipped cream around the edges. Use about 1/6 of the cream in total. Then spoon half of the sour cherries and syrup on top of the cream but inside the whipped cream ring. The ring ensures that the cherry filling stays in the cake and that no syrup runs out on the sides. Then spoon more whipped cream onto the cherries and distribute evenly on top (another ⅙ of the cream, so that now a total of about ⅓ of the cream has been used). Place the second cake layer on top and repeat.

Step 10

Place the third cake layer on top and distribute the remaining ⅓ of the whipped cream over the entire cake and around the sides to lightly frost the outside of the cake. Chill in the refrigerator for at least 4 hours, preferably overnight.

Step 11

Before serving, decorate with chocolate shavings, cherries, and additional whipped cream to your liking. Store the cake in an airtight container in the fridge for up to 3 days.
