Answer:
I would use a proportion for each ingredient:
Cup sugar
4:10=½:x (10×½)÷4= 1,25 cup sugar
Cup brown sugar:
4:10=¼:x (10×¼)÷4= 0.625 cup brown sugar
Peanut butter
4:10=⅔:x (10×⅔)÷4= 1,65 cup peanut butter
Cup oats
2×¼ = ½
4:10=½:x (10×½)÷4= 1,25 cup oats
Cup milk
4:10=¾:x (10×¾)÷4= 1,875 cup milk
Tsp salt
4:10=1:x (10×1)÷4= 2,5 tsp salt
2 tbsp cocoa
4:10=2:x (10×2)÷4= 5 tbsp cocoa
1 tsp vanilla
4:10=1:x (10×1)÷4= 2,5 tsp vanilla
2 eggs
4:10=2:x (10×2)÷4= 5 eggs
3 cups flour
4:10=3:x (10×3)÷4= 7,5 cups flour
12 oz nuts
4:10=12:x (10×12)÷4= 30 oz nuts
