Place your popsicle molds in the freezer beforehand. This will help accelerate the freezing process.
Blend the strawberries, Stevia, heavy cream and almond milk until fully combined. Let this blend for about a minute so the cream has a chance to aerate and whip.
Then throw your pistachios into the mix, and stir, do not blend! You can also use walnuts, cashews or pecans!
Pour the creamsicle mix into your cold popsicle molds and insert the bases. Freeze about 2 hours or until set.
To remove the creamsicles, allow hot water to run against the outside of the popsicle molds. This will melt some of the ice cream that sticks the creamsicles to the molds. Then gently pull on the bases until your ice cream is out.
