A allrecipes.com question about cake?

Question

I like this site: allrecipes.com

but I can't understand why do they give two sets of ingredients?

Take a look at this page:
http://allrecipes.com/Recipe/Peanut-Butter-Cake-V/Detail.aspx

They first state:
# 1/2 cup all-purpose flour
# 1/2 cup packed brown sugar
# 1/4 cup creamy peanut butter
# 3 tablespoons butter

give a space and then add:
# 2 cups all-purpose flour
# 1 cup packed brown sugar
# 2 teaspoons baking powder
# 1/2 teaspoon baking soda
# 1/4 teaspoon salt
# 1 cup milk
# 2 eggs
# 1/2 cup peanut butter
# 1/4 cup butter, softened

why do they give two sets of recipes?

Answer 1

The first part is for the streusel topping, second part is the cake.

Answer 2

Its so simple ,this cake has a crumblike topping.So thats why there are 2 parts.
First set of INGREDIENTS for TOPPING .
Second set of INGREDIENTS for cake.
1 ..In first part you will make topping,
2....In 2nd you make batter for cake.
So thats why they gave 2 lists of ingredients,
To make CRUMBLIKE TOPPING.

1/2 cup all-purpose flour
1/2 cup packed brown sugar
1/4 cup creamy peanut butter
3 tablespoons butter
Method:
In a small bowl, combine 1/2 cup flour and 1/2 cup brown sugar. Cut in 1/4 cup peanut butter and 3 tablespoons butter until mixture resembles coarse crumbs. Set aside.

For BATTER for CAKE.
2 cups all-purpose flour
1 cup packed brown sugar
2 teaspoons baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
1 cup milk
2 eggs
1/2 cup peanut butter
1/4 cup butter, softened
Method:
In a large bowl, mix together 2 cups flour, 1 cup brown sugar, baking powder, baking soda and salt. Make a well in the center and pour in the milk, eggs, 1/2 cup peanut butter and 1/4 cup butter. Mix well and pour into prepared pan.

The FINAL STEP,
Now on that PREPARED PAN,you have to sprinkle streusel (crumbleike topping you made )
Bake in the preheated oven for 30 minutes, or until a toothpick inserted into the center of the cake comes out clean. Allow to cool.........
