Preparation Instructions
TO MAKE THE CUPCAKES
Preheat your oven to 350˚ (I did not need to adjust anything for altitude, I'm at 5600').
Prepare a cupcake pan by lining with paper liners and set aside.
In a medium mixing bowl, combine the flour, corn starch, baking powder, salt, baking soda and 1½ cups of the sugar, set aside.
In another medium mixing bowl (see? lots of bowls) combine the melted butter, buttermilk, rum, yogurt, vanilla, and egg yolks, set aside.
Now. In the bowl of an electric mixer fitted with the whisk attachment whisk the egg whites until just foamy, them sprinkle the remaining ¼ cup of sugar into the whites, whisk to stiff peaks.
Now pour the stiffened whites into yet another bowl.
Dump the flour mixture into the empty mixer bowl and pour in the rum mixture.
Turn mixer to medium and beat until just combined, scraping the sides of the bowl at least once to ensure even mixing.
Fold ⅓ of the egg whites into the mixture, then add the remaining whites and fold, gently, until no white streaks remain.
Scoop about 4 tablespoons into each muffin cup and then bake until a toothpick inserted in the center comes out clean, about 25-30 minutes.
Remove from oven to cool on a wire rack. TO MAKE THE BUTTER RUM SAUCE
Place the butter, water and sugar in a medium saucepan over medium heat.
Once the butter has melted, bring the mixture to a boil for 5 minutes and then remove from heat.
Slowly (carefully) pour the rum in, it will foam up so go slow.
**If you want the rum to be cooked, add it in the beginning with the butter and cook it the 5 minutes.
Set aside to cool. TO MAKE THE BUTTERSCOTCH SAUCE
Melt the butter in a medium skillet over medium heat.
Add the brown sugar and ¼ cup of the cream, whisk until smooth.
Bring to a boil for 3 minutes.
Remove from heat and add the 6 tablespoons of cream, whisk until smooth.
Let cool for about 10 minutes and then add the vanilla. TO MAKE THE BUTTERCREAM
Place your mixer bowl over a pan of boiling water.
Add the egg whites, whole egg and sugar.
Whisk until the mixture is hot and the sugar has dissolved.
Place the bowl on the mixer stand and attach the whisk. Whisk for 10 minutes, until the mixture has cooled and is thick.
Lower the mixer speed to medium and a tablespoon at a time, add the cream cheese and butter until it's all in there.
Beat the mixture until smooth and then add the vanilla. TO ASSEMBLE THE CUPCAKES
Once the buttered rum sauce and the butterscotch sauce have both cooled to room temperature you are ready to assemble.
With a tooth pick poke holes all over the cupcakes.
Then spoon the buttered rum sauce, a teaspoon at a time over each cupcake. I did about 4 teaspoons per cupcake.
Let those sort of cool so the sauce dries.
Then pipe your frosting on and drizzle with the butterscotch.
