Pairs Well With
We really only do this recipe on any day that we feel like baking.
I chose this recipe because I like the chocolate chip cookie bars that my mom and I make. CHEMISTRY INFO: A chemical change that would be happening is the change of color when the cookies are done. Another chemical change is the cookie batter getting solid when it bakes. A physical change that would be occurring is when I would mix all the ingredients together. Another physical change is changing the shape of the dough.
