Oh Sweet Day!

Baby Gender Reveal Cupcake



Over the past weekend, I made these cuties for one of my special friends who’s expecting her first child. The idea came up pretty quickly because I’ve made these before for one of my clients. Nothing brand-new, but this is one of the recipes that I would love to revisit over and over again. These cupcakes look chic on the outside and adorable inside. They aren’t only great for revealing baby gender, they can be customized for any party celebrations or holiday events. I made a couple extra for my kids who were fighting to eat all so they could see the colour inside.


The cupcakes taste incredibly chocolate-y with the moist chocolate cake and the decadent ganache. The inside can be filled with buttercream, cream cheese frosting, or mostly used marshmallow frosting for fauxstess cupcakes. Again, I used my beloved one-bowl chocolate cake recipe which is unbelievably easy that a mind-blowing result.

Ingredients (12 regular sized cupcakes):

Chocolate Cake
1 cup granulated sugar
3/4 cup plus 2 tablespoons all-purpose flour
1/4 cup plus 2 tablespoons unsweetened cocoa powder, sifted
3/4 teaspoon baking powder
3/4 teaspoon baking soda
1/2 teaspoon salt
1 large egg, room temperature
1/2 cup sour cream, room temperature
1/4 cup canola oil
1 tablespoon vanilla extract
1/2 cup boiling water
Vanilla Buttercream Frosting
1 stick unsalted butter, room temperature
1 cup powdered sugar
1/2 teaspoon vanilla extract
1 tablespoon heavy cream
Blue or pink food coloring paste
Chocolate Ganache
100 grams dark chocolate, cut into small chunks
1/3 cup heavy cream
1/2 tablespoon corn syrup


To prepare cupcake, preheat oven to 350F. Grease muffin tin or line with muffin liners.

In a large bowl, mix together sugar, flour, cocoa powder, baking powder, baking soda and salt.

Crack in the egg, spoon in the sour cream, and pour in the oil and the vanilla. Mix with a wooden spoon until just combined.

Pour in the boiling water, and slowly mix until smooth and liquidy.

Divide batter evenly among prepared muffin cups, about halfway full. Transfer muffin tin to oven and bake for 15 to 18 minutes. Transfer muffin tin to a wire rack and let cupcakes cool completely.

To prepare buttercream, beat butter for a few minutes in a standing mixer with the paddle attachment on medium speed. Add powdered sugar and turn your mixer on low, beat until the sugar incorporates with the butter. Add vanilla and heavy cream, beat on medium speed for another 3 minutes, or until buttercream becomes light and fluffy.

Transfer 1/3 of the buttercream to a pastry bag fitted with a small plain pastry tip. Set aside.

Add coloring paste, one drop at a time, to the rest of the buttercream, continue beating until the color is nicely blended.

Using a small pairing knife, cut off the top of the cupcake in the shape of a cone. Flip the top over and cut off the cone. Fill the cavity with a teaspoon or two of frosting. Replace top.

To prepare ganache, place the chocolate, heavy cream and corn syrup in a medium heatproof bowl over a pot of simmering water. Stir the mixture using a wooden spoon until melted and smooth, about 5 minutes.

Grab each cupcake with its bottom, dip cupcake in the ganache to coat the top, let excess drip off. Place cupcakes in refrigerator for 10 minutes to set the ganache.

Pipe a question mark with the reserved buttercream on each cupcake.
