Do I need to create a double boiler to melt the chocolate and butter?

It’s not necessary, but I highly recommend using the double boiler setup. It will protect the chocolate from high heat, which can cause chocolate to seize and become thick, lumpy, and grainy.

Can this easy chocolate fudge cake be made into cupcakes?

Yes, you can fill cupcake liners halfway and bake for 18-20 minutes or until a toothpick inserted in the center comes out clean.

How do I know when the cake is done baking?

The cake will begin to pull away from the sides of the pan. When you gently press into the top of the cake, it will spring back.

Instructions

Cake

Preheat the oven to 350°F/177°C. Line a 9x9-inch square pan with parchment paper so it hangs off the edges.
In a large bowl, whisk the flour, sugar, cocoa powder, baking soda, baking powder, and salt.
In a medium bowl, whisk the sour cream, coffee, oil, egg, yolk, and vanilla.
Pour the wet ingredients into the dry ingredients and whisk for 1 minute to combine.
Pour the batter into the prepared pan.
Bake the cake for 24-27 minutes or until a toothpick inserted in the center comes out clean.
Cool the cake in the pan for 15 minutes and then transfer it to a wire rack to cool completely before frosting.

Fudge Frosting

In a medium heatproof bowl set over a small saucepan filled with an inch of simmering water, add the chocolate, butter, and heavy cream. Stir frequently until the mixture is completely melted and smooth.
Pour the chocolate mixture into a large bowl. Whisk in the powdered sugar and vanilla until smooth.
Allow the frosting to cool, stirring occasionally, until it's a spreadable consistency. Frost the cake as desired.
