Ingredients [Pastry Cream]:
- 4 large egg yolks
- 1/2 cup sugar
- 1/4 cup cornstarch
- Pinch of salt

(A conversion table can be found here.)
Directions [Pastry Cream]:
Whisk egg yolks until smooth in a large bowl. Combine sugar, cornstarch, and salt in a medium saucepan, and heat over medium. Stirring constantly, gradually add milk in a slow, steady stream, and cook until mixture thickens and begins to bubble, about 5 minutes.
Whisking constantly, slowly pour one third of the milk mixture into egg yolks (this step is called tempering, which keeps the yolks from curdling). Pour mixture into remaining milk mixture in saucepan. Cook over medium heat, whisking constantly, until mixture comes to a full boil and is thick enough to hold its shape when lifted with a spoon, 2 to 4 minutes. Remove from heat; stir in vanilla.
Strain mixture through a fine sieve into a heatproof bowl. Cover with parchment paper or plastic wrap, pressing it directly on surface to prevent a skin from forming. Refrigerate until chilled and firm, at least 2 hours (or up to 2 days).
Preheat oven to 350 degrees. Brush standard muffin tins with butter; dust with cocoa powder, tapping out excess.
Whisk together flour, cocoa, baking soda, and salt. With an electric mixer on medium-high speed, cream butter and granulated sugar until pale and fluffy. Add brown sugar, and beat until fluffy. Add eggs, one at a time, beating until well incorporated and scraping down sides of bowl as needed. Mix in sour cream. Reduce speed to low. Add flour mixture in three batches, alternating with two additions of buttermilk, and mixing until just combined after each.
Divide batter evenly among prepared cups, filling each three-quarters full. Bake, rotating tins halfway through, until tops are firm to the touch and a cake tester inserted in centers comes out clean, about 20 minutes. Transfer tins to wire racks to cool completely before removing cupcakes.
To finish, drain cherries, reserving 1/4 cup plus 2 tablespoons syrup. Cut each cherry in half. Combine reserved syrup and kirsch in a small bowl. Using a serrated knife (and a gentle sawing motion), split cupcakes in half horizontally. Brush both cut sides with kirsch mixture. Arrange halved cherries over cupcake bottoms; spoon about 1 heaping tablespoon pastry cream evenly over cherries. Replace top halves.
Make frosting: Place chocolate in a medium-size heatproof bowl. Bring cream and corn syrup just to a simmer in a small saucepan over medium-high heat; pour mixture over chocolate. Let stand, without stirring, until chocolate begins to melt. Using a flexible spatula, gently stir chocolate and cream until totally combined; begin near the center of the bowl and gradually work your way toward the edge, pulling in as much chocolate as possible, until the mixture is smooth and glossy. (If any chocolate pieces remain, strain mixture through a fine sieve and discard solids.)
Shiny chocolate glaze variation: Reduce amount of chocolate to 2 ounces. After pouring mixture over chocolate, let mixture stand 5 minutes before slowly whisking until smooth and combined. Use immediately, without straining
Spoon 2 tablespoons glaze over tops. Refrigerate 30 minutes before serving.
