by wind and water. These little bits of our earth are washed downstream where they settle to the bottom of the rivers, lakes, and oceans. Layer after layer of eroded earth is deposited on top of each. These layers are pressed down more and more through time, until the bottom layers slowly turn into rocks. There's your little science lesson for this post! These cookie bars are layered and pressed down like sedimentary rocks, so it was a fun way to teach kids about the rocks.
Now for the delicious part!
Sedimentary Rock Cookie Bars Recipe
Cooking spray or other nonstick product
1/2 cup melted butter
2-3 cups vanilla wafer cookies (use as much as desired)
1 can (14oz.) sweetened condensed milk
1/2 cup chocolate chips
1/2 cup white chocolate chips
1/2 cup broken pecan pieces
(If you really have a sweet tooth, you can use 1 cup each chocolate chips, white chocolate chips, and pecans. I prefer only the 1/2 cup each.)
1. Spray the bottom of 13x9 pan with cooking spray to avoid sticking (I always forget this step!)
2. Melt butter and pour into bottom of 13x9 pan
3. Crush vanilla wafers with rolling pin (it's okay to have a few small pieces)
4. Sprinkle broken vanilla wafers evenly on top of butter.
5. Pour can of sweetened condensed milk over cookies
6. Sprinkle chocolate chips, white chocolate chips, and nuts over condensed milk (add or delete amount as desired- I believe the original recipe calls for 1 cup of each, but it was way too much for me)
7. Gently press down the layers
8. Bake on 350°F for approximately 25-30 minutes (I usually only do 25 and they're great)
