Making the Oreo Cupcakes

The trick to these cupcakes is adding sour cream to the cupcake batter to make the cupcake lighter and airier and to set a balance with the Oreo buttercream frosting.  The end result is a smooth and creamier batter. Adding sour cream to the batter makes the muffin tins more full and makes for a taller cupcake.

I used a cookie scoop to evenly fill the liners.  Of course, if you don't have a cookie scoop, try to fill the liners about halfway full. As a result, you'll have tall, full cupcakes and a mouth full of chocolate.

The trick to making the Oreo buttercream frosting is to add milk in increments so the mixture doesn't become hard to blend.

Additionally, adding the milk slowly keeps the mixture creamy and helps incorporate the ingredients to create a consistently textured frosting.

Topping these cupcakes off with a whole Oreo cookie gives an inviting presentation and an adorable look. These cupcakes would be great for classrooms, get-togethers and special occasions such as Valentine's Day. What better way to tell someone you love them than to bake them something from the heart?

If you're looking for a smaller cupcake you can bake these in mini cupcake tins.  You will need to adjust the baking time to 11-14 minutes and use mini Oreos for decoration. The batter will make about 48 mini cupcakes.

Hi. What is the equivalent of one and half butter in grams?
