Reverse Creaming Method:

This is my classic chocolate and vanilla marble snacking cake made with the reverse creaming method.

The reverse creaming method is a technique where you beat softened butter into the dry ingredients. The butter coats the flour, which creates a barrier and slows the creation of gluten when it is mixed with the liquid in the recipe. You end up with a more tender, velvety cake texture.The reverse creaming method was introduced by Rose Levy Beranbaum in the early 1980s. I’ve made this cake using the regular method for mixing cakes and the reverse creaming with exactly the same ingredients, and I can tell you it does make a difference. Give it a try, you won’t be disappointed.

TIPS FOR BUTTERCREAM SUCCESS:

Make sure that your butter is soft. This will ensure that you only have to mix the minimum amount of time to get a smooth and homogeneous frosting.
Beat on the lowest speed of your mixer. Beating at a high speed for an extended amount of time will incorporate too much air into the frosting and will not be smooth. Don’t be tempted to speed the process up by increasing the mixture speed, be patient and you will be rewarded with beautifully smooth buttercream!
Use the frosting immediately.
