Vanilla Pastry Studio makes the best cupcakes in Pittsburgh, no doubt.
I have had their cupcakes twice, both of them were chocolate cupcakes but different buttercream. I don't remember the flavor of my first cupcake, but the second time was peanut butter.
The peanut butter chocolate cupcake was amazingly delicious. The buttercream was full of peanut butter flavor and slightly salty as well. It goes very, very well with the cake on the bottom. The butter cream is fluffy and light, and not too sweet. It makes the overall taste and texture of the buttercream not too heavy.
Same with the cupcake below - its soft and airy, and not too sweet at all. I felt like the cake could had have more chocolate flavor to accompany the buttercream, but it was overall still amazing.
What makes Vanilla's cupcakes so amazing is definitely the light and airy-ness of the buttercream and cake. The combination produces a dessert that is not too heavy, but also amazing and flavorful. I don't even like cupcakes, but I love Vanilla's. It is the best cupcake I have ever eaten in my life.
