This was shared in a lchf group I am in and you guys have to try it.
1 cup heavy whipping cream
2 Tablespoons unsweetened cocoa powder
3 Tablespoons suxgar subsititue, I used stevia, they say to use the confectioners version but I dont have any
1 teaspoon vanilla
Wisk it until its fluffy and creamy and wonderful. I have mine in fridge getting cooler. Store in fridge. You can add sugar free chocolate chips too and maybe even add a sugar free flavor of your choice instead of cocoa powder.
