How to Make It

Step 1    Make the cupcakes

Preheat the oven to 350°. Line a 12-cup muffin tin with paper liners. In a medium bowl, whisk the flour with the baking powder and salt.

Step 2    Make the cupcakes

In another medium bowl, using a handheld electric mixer, beat the butter and the granulated sugar at medium speed until fluffy, about 3 minutes. Beat in the eggs, one at a time, then beat in the vanilla bean seeds and vanilla extract. With the mixer at low speed, beat in half the flour mixture, then all of the milk, followed by the remaining flour mixture, until well combined.

Step 3    Make the cupcakes

Divide the batter among the muffin cups, filling each about two-thirds full. Bake the cupcakes until a toothpick inserted comes out clean, about 20 minutes. Let cool completely on a wire rack.

Step 4    Meanwhile, make the frosting

In a large heatproof bowl set over a saucepan of simmering water, whisk the chocolate with the butter and corn syrup until smooth; remove from the heat and let cool to almost room temperature, about 5 minutes. Whisk in the sour cream, salt and vanilla. Using a handheld electric mixer, gradually beat in the confectioners’ sugar until smooth.

Step 5    Meanwhile, make the frosting

Spread the cupcakes with the frosting and serve.

Make Ahead

The frosted cupcakes can be stored in an airtight container for up to 2 days.

Review Body: We make Gluten Free and Vegan foods all the time. The texture and flavor of these cupcakes are not very good and the frosting is way too sweet. We won't be making these again :( I wish they had turned out better.

Review Body: I made these for the office for my co-worker who has to eat gluten free. They were a hit even among the gluten eaters! I was worried about using sour cream in the icing because I don't like the taste of sour cream. However, I couldn't taste the sour cream; only one person could and she loved it and asked for extra icing. The flour recipe is very good.
