DIY Cookie Butter
1 c crushed cookies
1/2 c powdered sugar
1/4 c water
1/4 c olive oil
To make, crumble cookies into food processor and pulse until fine powder. Then add oil and water and process for a minute. Slowly add powdered sugar and let process until thick and creamy. Scoop into jar or bowl with a good lid. Use on toast, crackers, waffles, pancakes, or as frosting /glaze on cake, or whatever! Warm in the microwave for 30 seconds and drizzle as topping over ice cream.
My advice is to use hard cookies, like chocolate chip or snicker doodles. Cream filled cookies tend to separate. The absolute best is to use homemade cookies, that way you are certain of no extra ingredients you don't want. The oil you use can also vary- I suggest coconut oil or olive oil.
However you put this together, it is definitely cheaper to make at home, (Total price for what I made was about $0.80) and quick to make too!
Your kids will love the alternate, and you will love both the price and ease.
