Using a 2-1/4 inch (or size of your choice) cookie cutter, cut circles from cake. If using a 2-1/4 inch size, you should get 20 circles. Be sure to cut each one close together.

Mash raspberries and add to cream cheese/butter mixture. Mix on medium speed until thoroughly combined.

Add powdered sugar in small amounts, mixing after each until desired consistency. Depending on the juiciness of your berries, you may need to add additional powdered sugar.
