Add ½ cup half & half and the white chocolate chips to a medium saucepan and heat over low heat. Stirring continuously, continue to heat until the chocolate chips have melted and the mixture is smooth (do not simmer or boil).
Add the remaining ingredients and continue to stir until everything is dissolved and smooth.
Remove from heat and allow to sit at room temperature for 15 minutes, then transfer to a mason jar or other container. Store in the fridge for up to 2 weeks.
Note: Once completely cooled, it may have hardened milk solids on the top. You can mix those back in or skim them off for a smoother creamer.
