Place liners in teh cavities of a cupcake pan and set aside
To make the chocolate cake
In a large mixing bowl, combine sugar, sour cream, oil, egg, baking powder, and salt. Mix to combine.
Add in the cocoa powder, coffee, vanilla, and flour. Mix well -- being sure to stop and scrape the sides of the bowl occasionally.
Fill the cupcake liners about ⅔ full with batter.
To make the cherry sauce
Ensure that all seeds and stems have been removed from the cherries.
Combine the chopped cherries, lemon juice and sugar in a small sauce pan and simmer over low heat for approximately 20 minutes or until the cherries have liquefied. Remove from the heat and allow to cool before decorating the cupcakes.
Bake in preheated oven for 16-18 minutes or until a toothpick inserted in the center comes out clean.
Allow to cool completely.
To make the stabilized whipped cream
Combine the gelatin and water and microwave for approximately 30 seconds. Stir to ensure the gelatin is melted and allow to cool slightly while making the whipped cream.
In the bowl of a stand mixer, combine the heavy cream, powdered sugar, and vanilla. Beat on high speed with the whisk attachment for about 2-3 minutes or until stiff peaks form.
Drizzle the water gelatin mixture over the whipped cream and gently fold in by hand until well combined.
Transfer the whipped cream to a pastry bag fitted with a large star tip.
Assembling the black forest cupcakes
Once the cupcakes have cooled on a wire rack, the cherry sauce has cooled and the whipping cream has been made, you’re ready to decorate. Gently pipe a swirl of whipping cream on each cupcake.
Using a spoon, scoop out a cherry and gently place on top of the whipping cream. The sauce will drip down the sides of the cupcake. Add more if desired.
