Add the half & half, sugar, pistachio cream, and heavy cream to a small saucepan and heat over medium-low heat. Whisk the creamer until everything is melted and well combined.
Remove from heat and whisk in the almond extract.
Allow to cool at room temperature for 15 minutes, then transfer to a mason jar or other airtight container and store in the fridge for up to 2 weeks!
