How many cake mixes (ducan hines) sp will it take for the following pan
16 in round
10 in round
Depending on the high or number of fillings. I'm thinking for the 16 you'll need 3 to 4. For 14 about 3 and for a 10 you need 2. I like to make my cakes high, about 4in.
Here...bookmark this page. It will tell you how many cups are needed in a pan as well as servings:
You might try to WASC your recipe because it gives more bulk to the cake and makes it sturdier.
I use this chart.
With DH cake mix, they generally make 5-6 cups of batter, but it varies on flavor. White mix usually makes the lower end, around 5, chocolate falls in the middle, and the only one I know of that makes (or did) a full 6 cups of batter is the Golden Butter Recipe.
As was mentioned using a recipe like the WASC or the extender recipes you can bulk up your cake mixes, and add about two cups more batter per mix.
