I got a fun, new cookbook from a friend for Christmas. I needed a treat to bribe colleagues to come to a meeting. I think I found just the right recipe.
Chocolate Sour Cream Cupcakes with Vanilla Marshmallow Buttercream
Cupcakes:
4 oz unsweetened chocolate
2 C sugar
1 1/2 C all-purpose flour
3/4 tsp baking soda
1/2 tsp salt
1 C hot strong brewed coffee
1/2 C sour cream, room temperature
1/2 C vegetable oil
2 large eggs, lightly beaten
Frosting:
3 large egg whites
1 C sugar
3 sticks (36 oz) unsalted butter, each cut into 10 pieces, room temperature
1 Tbsp vanilla extract
Cupcakes:
Preheat oven to 345 F. Place liners in cupcake pan.
Melt chocolate in a double boiler. Sift sugar, flour, baking soda, and salt. Blend hot coffee, sour cream, and vegetable oil with a whisk.
With mixer on low speed, add coffee mixture to dry ingredients. Blend for about 45 seconds. Scrape, as needed.
Add eggs one at a time. Scrape the bowl each time. Add melted chocolate. Mix until batter is uniform in color.
Divide batter evenly in cupcake liners. Bake for about 20 minutes.
Frosting:
Whisk egg whites and sugar in a double boiler until mixture is opaque, warm to the touch, and sugar has dissolved, 4 to 5 minutes.
Trasnfer to mixing bowl. Use electric mixer and whisk attachment to beat (medium-high speed) until mixture is tepid, 5 to 7 minutes.
With mixer still on, add butter 2 to 3 pieces at a time. Stop frequently to scrape sides of bowl. Add vanilla and continue beating until light and fluffy, additional 1 to 2 minutes.
Notes:
I may have overcooked these just a little. They got crunchy on top and stuck a little to the liner. They still tasted great, though.
And, the frosting was a success. It tasted great, but was a little heavier than I wanted it to be. I would imagine that was the three sticks of butter.
I tried to fill the cupcakes with chocolate ganache. I didn't have the right tools, though. I think I'm going to need to get
one of these.
