I don't know about how much cream because I always use the marshmallows. My recipes is:
5 and 1/2 cups of rice crispy cereal (I always use store brand)
1/4 cup margarine
40 large marshmallows
Put the cereal in a large bowl. Butter a 9 inch by 13 inch casserole dish.
Melt the margarine over low heat on the stove. Once melted, add the marshmallows and stir constantly until the marshmallows are melted.
Pour over the cereal and mix well. Scoop into the buttered casserole dish and spread out and push, gently, to flatten the top. Allow to cool (about 30 minutes). Then you can cut and serve.
I've never used the cream so I do not know how much is in one jar. But I looked it up online and saw that 1 jar (7 and a half ounces) is what you need for 1 batch of treats.
