      INSTRUCTIONS
      

      
      

1. In a medium-sized bowl, cream the butter and cream cheese together with a mixer until fully combined. It helps if the butter and cream cheese have softened some before doing this (you can zap them in the microwave for 15 seconds to help)
   
2. OPTIONAL: If you are using a granulated sweetener, throw it into a blender or food processor. Blend the sweetener until it is fine, fluffy, and powdered. Powdering your sweetener makes for a smoother frosting.
   
3. Add the sweetener and flavorings to your bowl and beat slowly until the sweetener is incorporated (go slow to avoid it getting blown into the air)
   
4. Once the sweetener is incorporated, beat on high for 2 minute or until fluffy
   
5. Use a piping bag (something like these) to pipe the frosting onto whatever you’d like (including directly into your mouth!).
   
6. Enjoy! Keep any icing in an airtight container in your fridge. If refrigerated, they should be good for about a week. (up to 3 months if kept in the freezer)
