There are many ways to eat a cupcake from Buttercream Cupcakes & Coffee in Coral Gables. You can peel away the chocolate Oreo's baking cup ($2.75 each, $33 per baker's dozen) and then devour its butter-filled frosting one nibble at a time. You can tear off the top of an orange cupcake and then lick the orange-zest-speckled buttercream bit by bit. You could try a myriad of methods with the shop's 18 other flavors, which include chocolate-peanut butter, lime, mocha, and red velvet. Those are all very good trials. But after sampling all of Buttercream's moist, fluffy cakes, you should really try this: Remove the cupcake's wrapping, pull off its spongy bottom, plop it atop the frosting, and eat. Enjoy the beauty of a self-made, sweet Buttercream cupcake sandwich.
