¼cup (59 ml)(or to taste) raspberry puree OR a handful (about 1 cup, or more to taste) of fresh, washed, and dried raspberries

Directions

For the Cupcakes:
Preheat oven to 350° F and line a muffin/cupcake pan with your favorite cupcake liners.
In the bowl of electric mixer fitted with the paddle attachment, sift flour, sugar, cocoa powder, baking soda, baking powder, cornstarch and salt.
In a medium bowl or measuring cup, combine the buttermilk, coffee, oil, egg and vanilla.

Add liquid mixture to dry ingredients and mix for 2 minutes on medium speed (you may need the plastic splash guard that comes with mixer), Divide batter among (2/3 full or just less) liners. Batter will be liquidy, and cupcakes will rise.
Bake for 15-17 minutes, or until toothpick or skewer comes out with a few crumbs. Try not to over-bake. 

Carefully remove cupcakes from the pan immediately (it’s hot!), and place them on a wire rack until completely cool.

For the Raspberry Swiss Meringue Buttercream:

Wipe the bowl of an electric mixer with paper towel and lemon juice, to remove any trace of grease. Add egg whites and sugar, and simmer over a pot of water (not boiling), whisking constantly but gently, until temperature reaches 160°F, or if you don’t have a candy thermometer, until the sugar has completely dissolved and the egg whites are hot.

With whisk attachment of mixer, begin to whip until the meringue is thick, glossy, and the bottom of the bowl feels neutral to the touch (this can take up to 10 minutes or so). 

*Don’t begin adding butter until the bottom of the bowl feels neutral, and not warm.

Switch over to paddle attachment and, with mixer on low speed, add butter cubes, one at a time, until incorporated, and mix until it has reached a silky smooth texture (if curdles, keep mixing and it will come back to smooth). *If mixture is too runny, refrigerate for about 15 minutes and continue mixing with paddle attachment until it comes together. 

Add vanilla and salt, continuing to beat on low speed until well combined.
Add raspberry puree to taste or the fresh raspberries in small increments, and blend until combined. Add small amount of pink food coloring, if desired.

For the Glaze:
Place the chocolate and butter in a medium heatproof bowl over a pot of simmering water. Stir the mixture using a rubber spatula until melted and smooth. *Be careful to not get even a droplet of water into your bowl of chocolate and butter.

Assembly of the Dark Chocolate & Raspberry Cupcakes:
Fill a large pastry bag (18”) fitted with Ateco #887 (or the decorative tip of your choice) about 2/3 full and swirl the buttercream in a circular motion, beginning on the outside rim of the cupcake and moving inward. Gently release pressure when you reach the top of your swirl.
Drizzle the top of the cupcake with Dark Chocolate Glaze (~1 tablespoon each).

Top with a fresh raspberry and chocolate sprinkles (optional).

Cupcakes are best enjoyed the day they are made, but these keep particularly well in an airtight container at room temperature for up to 3 days (however, I’ve been known to eat them up to a week later, and they taste great!). If you do refrigerate, serve at room temperature—particularly Swiss Meringue Buttercream cupcakes, otherwise the buttercream is too hard and butter-like.
Notes:
*Essentially, this is vanilla Swiss Meringue Buttercream with some clean, dry, fresh raspberries into it. It doesn’t require many raspberries to give it a nice flavor, but it’s personal preference. You can also use seedless raspberry-puree for a smooth finish. Add a drop of pink food coloring for a touch more pink.
