Simple "Marbled" Cupcake

This simple cupcake came about to cheer up the little ones at home who were feeling under the weather... nothing fancy about it, except, my 4¾ year-old helped me make it - beating the eggs with a fork, measuring the flour and sugar, adding baking cases to the muffin pan, stirring and tasting the batter, and of course spreading the frosting.

We've been trying various kids art activities some of which involved simulating the marbling-effect or "colorful swirlies" as she calls it. And so when she added a few drops of purple food color, rather than blend it in uniformly, she decided to swirl it around a bit, just enough to leave streaks of purple in an otherwise plain cupcake batter. When scooped as-is and baked, it formed nice deep swirly patterns all around. Can use multiple colors and swirl them about to form interesting patterns in the batter before baking. (The quantity here made about 8 standard size muffins)

Ingredients
2 eggs
½ cup Smart Balance Omega 3™ butter
1/3 cup sugar
½ tsp baking powder
1 cup flour
food color

Frosting: Light Cream Cheese, (home-made) strawberry jam or plum jam - beaten together till fluffy
Sprinkles optional

Preparation

1. Pre-heat oven to 350°F; Beat the eggs and keep handy
2. Blend the sugar and butter together with an electric mixer till fluffy, about 2 minutes
3. Add the beaten eggs and continue to beat another 30-40 seconds
4. Sift the flour and baking powder together and slowly fold it into the wet ingredients mixture
5. Add a few drops of food color and swirl it around with a ladle
6. Scoop the batter into each of the baking cases in the muffin mold (or, simple spray the muffin mold with vegetable oil) to about 2/3rds full and bake in a 350°F oven for about 20-25 minutes, checking midway and turning the tray around if needed
7. When cool enough, spread some frosting on top, add some sprinkles and enjoy! Or chill in the fridge for a summer time snack
