Funfetti Shortbread Sandwich Cookies
These funfetti shortbread sandwich cookies are rich, buttery, and full of sprinkles! Sandwiched together with easy vanilla buttercream. The buttercream can be dyed any color desired and the funfetti sprinkles can be exchanged for any color of sprinkle. I dyed my buttercream pink and went with the funfetti sprinkles. These bite sized cookie sandwiches are perfect for cookie boxes or treat tins.
