Start by preparing your cookie dough filling. Mix butter and sugars until well combined. Stir in half and half and vanilla, stir until well combined. Add in flour and mini chocolate chips, stirring until well combined. Mixture may be very thick.
Cut Rice Krispies Treats Squares in half width wise, then in half again, to create four pieces from each square, which will make two cookie dough treats. Repeat with remaining Rice Krispies Treats Squares.
Place approximately 1 tablespoon of cookie dough onto 16 of the cut Rice Krispies Treat Squares. Top each with a second cut Rice Krispies Treat. Press sandwich together gently.
Melt chocolate according to package directions. Once melted, spoon a small amount of melted chocolate on top of a treat. Immediately place a decorative baseball pick into your treat, before the chocolate starts to set. Repeat with remaining treats. Allow chocolate to set up for approximately one hour. Store loosely covered. Enjoy!
