This is the FIRST CUPCAKE for my site, and I did NOT make this decision lightly… in truth, once I had the idea for this citrus-y, lemon-y, lime-y dessert, I knew that the Mountain Dew Cupcake simply HAD to be created. Just look at it. It’s like the headline should be “Cupcake Escapes from Kitchen and Rules the X-Games.”
BAM! Yeah, THAT just happened, right in your mouth.
CITRUS BATTER INGREDIENTS
- 1 box lemon cake mix (I used Duncan Hines Lemon Supreme)
- 3 eggs
- One 6-ounce cup lime yogurt (I used Yoplait Key Lime Pie flavor)
- 1/3 cup oil
- 3/4 cup water
MOUNTAIN DEW SWIRL INGREDIENTS
- Two 12-ounce cans Mountain Dew (about 3 cups)
- Juice of 1 lime (about 3-4 Tbsp)
- 2 Tbsp cornstarch
- 3/4 cup of the citrus batter, above
- 14 drops green food color
- 3 drops yellow food color
CITRUS FROSTING INGREDIENTS
- One tub lemon frosting (I used Duncan Hines Creamy Lemon)
- 3 drops green food color
- 2 drops yellow food color
- 3/4 cup sifted powdered sugar
Put on your shin guards and crash helmet. Keeping one hand on the handlebar of your BMX, use the other hand to simultaneously pour both cans of Mountain Dew into a medium saucepan. You will start with about 3 cups of liquid in the pan.
We’re going to reduce that Mountain Dew down to its intense, dewy essence. There are no rules on how to reduce Mountain Dew, so I made ‘em up: Pow! Boil that bad boy on high heat for about 15-20 minutes until about 3/4 cup of liquid remains.
During the 15 minutes when that’s boiling down, squeeze about 3-4 tablespoons of lime juice into a small bowl and mix in 2 tablespoons of cornstarch. Set that aside for later.
Check your boiling pan. When you have about 3/4 cup of molten Mountain Dew left, it’s time to move forward.
It may be hard to judge how much is in the pan, so you can use a heat-safe Pyrex glass measuring cup to check. That’s what I did.
Keeping the pan off of the heat, return The Dew to the saucepan, except for about 1/8 of a cup, which you will mix right into the cornstarch mixture. The goal is to get the cornstarch mixture warmed up a little.
Add cornstarch mixture to the pan, whisking it quickly, like you’re pedalling up an extreme hill on the BMX course. Don’t worry if you get flecks of lime goo on your face and apron — pretend it’s the mud you’re flinging onto the competitors behind you.
Return the mixture to medium or medium-high heat for just another minute or so, until it thickens up to the consistency of pudding. It will look a lot like lemon meringue pie filling at this point. This, my MD friends, is the basis for your Mountain Dew Goo. Pour it into a medium-sized bowl and set it aside while you make the cake batter.
Put all 5 of the batter ingredients into a large bowl and mix with an electric mixer for 2 minutes on medium speed.
It should be thick, smooth, and creamy. Don’t eat it.
Take about 3/4 cup of the lemon batter and add it to the bowl of the Dew Goo.
Mix together and then add 14 drops of green food coloring.
Getting close. Now add 3 drops of yellow food coloring. Mix until the color is even. You can tweak it to be greener or yellower based on your personal preference. (I found this particular shade to be a nice balance against the yellow of the batter. Just one DewGirl’s opinion.)
Set the green goo aside while you fill all your muffin cups about 1/4 full with the yellow batter. I used foil muffin cups in silver and green, left over from Christmas; they were just so Dew-like.
On top of that layer, add an edge-to-edge layer of the green Mountain Dew Goo. This layer should bring each muffin cup up to about half full.Be sure to spread the green from edge to edge so you can’t see any of the yellow batter.
Top off each cupcake with a final layer of the yellow batter, making sure to cover the green entirely. I found the easiest way to do this was to spoon a circle of batter around the outer edge of the cup and then cover over the middle. Each cup should be pretty full, about 3/4 to 5/6 full.
Bake at 350 F for 17-21 minutes, until a toothpick test reveals a nicely raised (but still slightly moist) and spongy-set cake. During baking, something wild happens to that green layer, which gets all loopy, swirly and tossed around as the batter rises and expands. You’ll see what I mean when you take your first bite.
Set aside to cool completely. In the meantime, mix your frosting. Put the pre-made lemon frosting into a medium bowl. Mix in 3 drops of green and 2 drops of yellow food coloring. Feel free to tweak until you get the Mountain-Dew color that YOU like.
Add 3/4 cup of powdered (or confectioners) sugar. Mix until it’s completely lump-free.
Sprinkles make everything better. My opinion: These Mountain Dew Cupcakes just do NOT look extreme without some garish garnish on top. POW! Now THAT’S better!
You don’t HAVE TO refrigerate these, but they are so much more refreshing when you do. Chill off on a summer day with one of these bad boys. YEAH!
Keep your eyes on the prize: the one, the only, Mountain Dew Cupcake!!
