# The Best Cupcake Combo

Do you know what a number cake is? Guess what — you’ve probably eaten one! That’s what cupcakes were called when they were first made in the 1800s. The first recipes called for 1 cup of butter, 2 cups of sugar, 3 cups of flour, 4 eggs…okay, and 1 cup of milk and 1 spoonful of baking soda. We now mix in other flavors and smear frosting on top. We love this set of cupcakes here because it puts each type of frosting (chocolate, coffee, and vanilla) on top of each cake flavor (chocolate and yellow). Of course, people like some frosting flavors more than others…so you have to do the math to see if you’ll get your favorite.

Wee ones: How many cupcakes can you count in each row going across?

Little kids: How many cupcakes can you count in the whole box? Bonus: If 4 of them have coffee frosting, how many don’t?

Big kids: If you instead had 3 kinds of cupcake cake — chocolate, yellow, and red velvet — with 5 kinds of frosting — chocolate, vanilla, coffee, cream cheese, and pink — how many combinations of 1 cake flavor and 1 frosting flavor could you come up with? Bonus: If you have 5 cake flavors and you want to make at least 32 different cake/icing pairs, how many icing flavors do you need to make?

The sky’s the limit: If the number of cake flavors and icing flavors add up to 10, and together they can make 24 cake/icing pairs, how many cake and icing flavors could there be?
