I had to look up what “cookie butter” (the first ingredient is in this recipe) Apparently it’s a “food paste made primarily from Speculoos cookies crumbs; fat such as vegetable oil, condensed milk or butter; flour and sugar. The ingredients are mixed until it becomes spreadable like nut butter.” – I had no idea this was a thing!!

1 container (14 oz) cookie butter
1 can (14 oz) sweetened condensed milk
3 eggs
1 teaspoon ground cinnamon
1 pouch (17.5 oz) Betty Crocker™ Cookie Mix Sugar
3/4 cup salted butter, melted
