Instructions
To make the cupcakes:
Make the cupcakes! Preheat the oven to 300° F and grease two 12-cupcake pans with either butter or cooking spray, or line with paper cupcake cups. In a medium bowl, sift together all of the dry cupcake ingredients (flour, sugar, cocoa powder, baking soda, baking powder, salt), and whisk to combine.
In a separate large bowl, whisk together the eggs, sour cream, canola oil, and vanilla extract until fully blended and creamy. Once combined, add in the dry ingredients and use a spatula or wooden spoon to mix. Fun step! Poor in that cup of piping hot coffee and stir until fully combined (it’ll take some working). Pour batter into the cupcake pans (each one should be about 2/3-3/4 full) and bake for 20-25 minutes or until a toothpick inserted into the middle of one of the cupcakes comes out clean. Remove from oven and let cool.
To make the marshmallow fluff:
In a small saucepan, combine the water, corn syrup and sugar over medium heat. Stir occasionally until all of the sugar dissolves, and then stop stirring immediately and let simmer (turn down to med-low heat). Insert your candy thermometer to check temp – this will take 5-10 minutes. Let the mixture simmer (do NOT stir it) until it reaches 240 degrees Fahrenheit (softball stage). While the mixture is cooking, make the meringue.
In a large, perfectly clean, dry bowl, begin beating your room temp egg whites with your electric mixer. If there is any oil or crumbs in the bowl or any drop of egg yolk, the egg whites will not get stiff, so make sure all implements are clean and dry and the egg whites are carefully separated. Beat egg whites until foamy and then add in the cream of tartar and continue to beat until soft peaks form. Let sit until your sugar mixture has reached softball stage.
Once the sugar syrup is at 240 degrees, immediately turn off heat, and, using heat pads (or a friend to help!), start beating egg whites again and slowly pour in the hot sugar mixture into the egg whites. Beat constantly until all of the sugar mixture has been added (pour in a slow stream, do not dump it in). Do not stop beating the egg whites! Continue to beat after all the sugar syrup has been added, until the bowl is back to room temperature (it will be very hot after adding the syrup). You can add a bag of frozen peas under the bowl or on the side to help cool the bowl as you beat the mixture. This will take 10 or so minutes, so be patient. As the bowl cools, the mixture will become thicker and stiffer and stickier as the marshmallow forms!
Once the bowl is room temp, you can stop beating the marshmallow. Scoop it into a piping bag and pipe onto the cooled cupcakes, then let sit for at least 5 minutes before dunking in chocolate shell.
To make the chocolate shell:
Combine the chocolate and canola oil in a microwave safe bowl and microwave for 45 seconds at a time, stirring in between, until chocolate is totally melted and combined with the oil. Let chocolate cool for five minutes before dunking cupcakes. Then, take one cupcake at a time, holding by the bottom of the cupcake, turn upside down and dunk in the chocolate, letting the chocolate drip for a few seconds before turning right side up and placing on a tray. Immediately freeze cupcakes for at least 15 minutes or refrigerate for at least 30 minutes to set chocolate, then serve!
