Muddy’s Bake Shop is most well-known for its Prozac Cupcakes. Now, don’t expect to find any prescription drugs in your cupcake or to cure anxiety or depression with these things. It’s just a name, k? Basically, they’re saying that these cupcakes are just THAT GOOD that they’ll chill you right out. So, what is a Prozac Cupcake? Chocolate cupcakes with chocolate buttercream icing and happy sprinkles (or SPRANKLES as they are known at Muddy’s!) on top for good measure.
