Simple Cupcakes in 3 Sizes

Cupcakes with sprinkles--inside and out.

Vanilla cupcakes in 3 sizes.

I decided to go super simple for my son's 11th birthday this year.  He really doesn't have strong opinions beyond "plain vanilla" cake, so I decided to mix things up by making three sizes of cupcakes from one Betty Crocker box of white cake mix.  Because I like sprinkles, I decided to make some with sprinkles and some without. (Max prefers withOUT.  He has texture issues...)
This manner of baking cupcakes made 6 jumbo, 6 regular, and 12 mini sized cupcakes.  I think I'm only posting this for the pictures because the "recipe" is nothing spectacular.

Simple Cupcakes in 3 Sizes

Ingredients
1 box white cake mix
3 eggs
1/3 cup canola oil
1 1/4 cups water
2 tablespoons rainbow nonpareils
1 container vanilla frosting
1/4 cup powdered sugar
more nonpareils

Directions
Preheat oven to 350 degrees F.
Prepare cupcake pans (one jumbo 6 cup pan; one regular 6 cup pan; and one mini 12 cup pan) by lining with white cupcake liners.
Mix cake mix, eggs, oil, and water on low for 30 seconds to combine.  Scrape the bowl and mix on medium for 2 minutes.  Pour half the batter into a large zip top bag.  Gently stir nonpareils into the remaining batter and then scrape into another large zip top bag.
With scissors, clip 1/2-inch of one corner of the sprinkle batter bag and fill half of each pan.  Then do the same with the plain batter. (The sprinkle batter should be done first because the colors start bleeding immediately.)
Bake the jumbo and regular pan for about 15 minutes, or until a toothpick inserted into the center comes out clean.  Then bake the mini pan for 8-10 minutes, or until a toothpick comes out clean.
Cool cupcakes on a wire rack.
In order to make this more complicated, I'm telling you that I whipped the canned frosting with 1/4 cup powdered sugar to make it more stiff and airy.  Then I frosted the cupcakes, sprinkling the frosted sprinkle cupcakes with more nonpareils immediately after frosting them.
Makes 24 cupcakes of varying sizes.
