STEM Sedimentary Rock Cookie Recipe and Activity

Years ago I copied a set of rock themed cookie recipes from teaching magazine. I wanted to make sedimentary rock, igneous rock, and metamorphic rock cookies with my students. Just this week I pulled out them out to make with my son. He has a wonderful time creating and test testing them. Your children will enjoy making them too. Today I am sharing the sedimentary rock cookie recipe. Watch for the other two cookie recipes to go up in the next few days.

Sedimentary Rock Cookie Recipe

Ingredients

1/2 cup of margarine

1 1/2 cups of graham cracker crumbs

1 can sweetened condensed milk

1 cup chocolate chips

1 1/3 cups of coconut

1 cup of chopped nuts (We used walnuts.)

Directions for Making the Sedimentary Cookies

Sedimentary rock has lots of layers. Most of the cookie creation process is going to adding layers of ingredients one at a time.

Preheat your over to 350 degrees.

Place the melted margarine in a 13″ by 9″ pan. Spread it with a spoon to make sure the whole bottom of the pan is covered.

Spread graham cracker crumbs on top of the margarine. Then you can use a spoon to make sure that the whole pan is covered with crumbs.

Now it is time to pour the can of sweetened condensed milk on top of the graham cracker crumbs.  You can smooth it out with a spoon too.

Then add a layer of chocolate chips on top of the milk.

Next shower the coconut over the chocolate chips.

The final layer you will add is the chopped nuts. If you have children aren’t huge fans of nuts or have a nut allergy, you can leave them off. We only placed nuts on one side of our pan.

Then it is time to press the layers together with the back of a spoon. Once the layers have been compressed, you can bake the sedimentary cookie bars for 25 to 30 minutes.

Sedimentary Rock Cookie Printable

I created a Sedimentary Rock Themed Cookie Bar STEM Activity printable you can use with your kids that shares the recipe, creation directions, and an area to diagram the cookie. Your children can work on creating the diagram while the cookies are baking.
