the recipes i used it for basically tells you to mix all the dry ingredients first and then the butter with some milk, once it's all moistened, you mix it for about 2 to 3 minutes until it's fluffy and then you add your eggs and the rest of the liquids.
i wish i had a picture of the cake but it was so good that we didn't have any left. the crumb was very nice, no tunnels.
the most important thing is to scrape the bowl more often than you would normally do. it's almost like a one bowl recipe too.
i guess i could try this with other recipes, although the ones i found were for chocolate and yellow cake.
