Sedimentary Rock Bars

We're studying rocks in science this month and the kids are loving it! We've found all sorts of neat online activities and games, as well as pictures and information. I'll share some interesting links in another post.

This post is about the food! Our science book had a recipe for Sedimentary Rock Bars to help illustrate the layers that make up this type of rock. I figured if they were yummy, the kids would remember how sedimentary rocks are formed.

Well, the bars are yummy. And the kids do remember. Mission accomplished!

To quote Mr. Lego -"These bars rock!" Oh, the dry sense of humor.

You don't have to be studying the formation of rocks to appreciate this delicious recipe, though. You probably already have the ingredients in your pantry. Or if you don't, you can substitute like I did.

Here's what you need:

1/2 cup butter, melted
1 1/2 cup vanilla wafer crumbs (I had none, so I used a combo of graham cracker and Ritz crackers)
1 (14 oz) can sweetened condensed milk
1/2 cup chocolate chips
1/2 cup peanut butter chips
1 cup chopped nuts

This is the Princess crushing up crumbs for me. The kids loved helping make these.

Pour the melted butter into a 9x13 pan. Sprinkle evenly with the crumbs. I liked having the Ritz crumbs in here. There was a slightly salty taste that really helped control the sweetness. I think I'll go with Ritz instead of vanilla wafers from now on.

Slowly pour the condensed milk over the crumbs. Try to make sure the whole pan is covered. Layer the chocolate chips and peanut butter chips next.

The last layer is the nuts. Sprinkle evenly over the top and gently press down.

Bake at 350 degrees for 20 minutes. Remove from the oven and let cool a little before cutting into bars.

See all those layers? The nuts on top really do resemble rocks! We loved making these and loved eating them even more. Nothing like a hands-on project to reinforce learning.

I love homeschooling!
