Simple and Easy Chocolate Cupcakes
You can use unsalted room temperature butter, however, it tastes fantastic with coconut oil. We filled these with a mix of chocolate and regular marshmallows (2 cups) that we melted over steam. See the picture, but whipped cream or whipped frosting, cream cheese frosting, would work perfectly too. You got to let the melted marshmallows cool down before filling the pastry bag, and of course, cupcakes should be also cooled completely.
