I scoured the internet but couldn't find anyone who had duplicated the recipe, but I did find this Mt. Dew cupcake recipe from The Geeky Hostess, which I worked from as a base.
In an interview with John Rivers, owner of the aforementioned 4Rivers Smokehouse, Mr. Rivers advised in making one's own soda-flavored cakes, the use of a soda reduction was key.
Making a soda reduction takes quite a bit longer than I realized. You'll wanna use at least two or three times the amount you want to end up with, about 3 cups. Start by bringing your soda to a nice rolling boil, then reduce heat, cover, and simmer for 1-2 hours until it becomes a syrup.
|Stir stir stir|
When done, mix 1/2 cup of your syrup reduction, and two eggs into your white or lemon cake mix (I used lemon for mine).
Bake at 350 for the time specified on your mix box (about 20 minutes) or until a toothpick/skewer inserted into the middle of cakes comes out clean.
For an extra kick of flavor, you can top each hot cupcake with a light drizzle of reserved syrup, creating a nice glaze.
While those babies cool, go ahead and start on your icing. You can either use a store-bought icing and add a tablespoon of Mt. Dew syrup and a squeeze each of lemon and lime, or you can go the from-scratch route, as I did.
Mix up your butter until it's nice and fluffy(ish), then add your lemon, lime, and Mt. Dew. Mix 'er up again, and start adding your powdered sugar a cup at a time until you get to the consistency you want.
|(NOTE: You'll wanna do this right before serving, as the Doritos chips on your cupcakes will go stale rather quickly)|
All in all, I'd say the flavor is... unique. I'm not in love with the icing recipe, as it had a very strong powdered sugar taste. The cake was good, and as noted the Doritos need to be added shortly before you're actually planning on eating them. :)
