A Beautiful Mess and give it a standing ovation. Here's what you need to know: Cookie Butter adapted from A Beautiful Mess 2 cups cookie crumbs
1/4 cup butter
1/2 cup sweetened condensed milk
1/4 cup evaporated milk
water as needed
Prepare cookie crumbs by pulsing cookies in a food processor. (If using sandwich cookies with a cream filling, remove the cream filling first.) Keep pulsing until you have two cups of fine powder. Transfer crumbs to a mixing bowl. In a small saucepan, heat the butter over low heat until melted, and then stir in the sweetened condensed milk and evaporated milk and continue stirring until completely combined. Pour 1/2 cup of the liquid into the cookie crumbs and mix together with a spoon. Keep adding small amounts of the liquid until the cookie butter is just wet enough to stay together. Depending on how dry the cookie is to begin with, you'll need more or less liquid. Buttery cookies (like the sugar cookies) won't require nearly as much as the drier cookies.
Once the cookie butter is blended, allow it to cool in the fridge for 1-2 hours. Remove from fridge and stir very small amounts of water (start with 1/8 teaspoon) into the mixture. Continue blending and stirring until you reach a smooth, butter-like consistency, adding butter as necessary. Once desired consistency is reached, cover butter and transfer to the refrigerator. It will keep up to two weeks!
