This cake is like a bread pudding, tasting like classic Danish butter cookies. It's an easy hack using a pack of Royal Dansk cookies, milk, and baking powder, baked in the original cookie tin.
Add 1 teaspoon of baking powder and 1 cup of milk to the 12 oz pack of Royal Dansk cookies in the food processor. Process until combined. You can use the same Royal Dansk container for baking; you don’t need parchment paper, but it can be used if desired for presentation. Bake at 375 degrees Fahrenheit for 25 minutes or until it is firm. Once baked, add crystal sugar sprinkles to give it a finish like the actual cookies.
