Lime Cupcakes with Chile-Mango Buttercream

A yummy summer treat, cool lime cupcakes topped with a sweet and spicy buttercream, perfect with iced black tea.

For the cupcakes:

4 egg whites

4 egg yolks

2 3/4 cup flour

1 1/2 tsp baking powder

1/4 tsp salt

1 cup butter, at room temperature

2 cups sugar

1 tbsp vanilla extract

3/4 cup milk

1/4 cup lime juice

Oven at 350 degrees.  Muffin tins lined or greased and floured.  With a mixer beat the egg whites until stiff peaks form, set aside.  Cream the butter and slowly add in the sugar.  While the butter and sugar are getting fluffy, sift flour, baking powder, salt and set aside.  Once the butter mixture is light, add egg yolks one at a time, beating well between additions.  Add vanilla extract to butter/sugar/egg mixture.  Add lime juice to the milk.  Using a spoon or spatula, add the flour alternating with the milk, about three additions of each.  Fold in the reserved egg whites.  Fill mini muffin tins about 3/4 full.  Bake.  Mine took about 19-21 minutes if I only had one pan in the oven at a time.  Test them often.  Cool before removing from pan.

For the buttercream:

1 cup butter, unsalted, softened

4+ cups powdered sugar

1/2 - 1 cup pureed mango

chile powder to taste

Cream the butter until fluffy, add about 1/2 cup pureed mango, beat until smooth.  Add powdered sugar gradually until you've added 3-4 cups, then add more pureed mango and the chile powder.  Add more powdered sugar until you reach a consistency you like.  If it is too thick, add some milk.  Done!

Assembly:

Frost cupcakes.  I garnished mine with lime zest and a green fondant rose.  Yay!
