I found this recipe in an issue of "Today's Parent", I made it for my daughter's second birthday a while back and she loved it, it was literally all over her face.
Ingredients:
Cupcakes
1/2 Cup unsweetened cocoa powder
2/3 Cup boiling water
1 1/2 Cup all purpose flour
1 Cup white sugar
2 tsp Baking powder
1/2 tsp Salt
1/2 Cup vegetable oil
2 Eggs
1 tsp Vanilla
1/2 Large bag of "Rolo" chocolate or something similar
Icing
3 tbsp Butter at room temperature
1 3/4 Cup icing sugar
1/4 Unsweetened cocoa powder
3 tbsp milk
1 tbsp Vanilla
Directions:
Preheat Oven to 350 F.
In a large bowl, whisk cocoa with boiling water until no lumps remain.
In a medium bowl, whisk flour with sugar, baking powder with salt.
Whisk oil into slightly cooled cocoa mixture, then whisk in eggs and vanilla.
Stir in flour mixture until combined. The mixture will be very thick.
Spoon batter into paper lined muffin cups.
Bake until batter is barely set, approx 8-10 minutes.
Remove partially baked cupcakes and push pieces of chocolate into the center.
Bake for another 8-10 minutes, then set on cooling rack.
For the icing beat butter in a large bowl.
Whisk icing sugar with cocoa to remove lumps.
Beat into butter, alternating with milk.
Beat in vanilla until icing is smooth.
Enjoy!!
