What ingredients do I need to make this frosting?
Butter— I use salted butter in just about every recipe. I prefer it, but you can definitely use unsalted and add salt to taste after mixing the ingredients.
Sweetener— My favorite way to make this recipe is to use powdered allulose. Allulose is newer on the keto scene, but it’s quickly gaining popularity because it tastes just like regular sugar, but doesn’t have a glycemic impact. Just like with erythritol and monk fruit, I deduct the “non-impact” carbs of allulose from the total carb count of a recipe and the fiber to get net carbs.
Also, if you can’t find powdered allulose like me, you can just use a spice grinder or coffee grinder to get the desired powder. Powder is important for this recipe, though, because otherwise you’ll end up with grainy frosting.
(Note: I’ve also made this recipe with powdered erythritol. It comes out fine, but it definitely has a cooling aftertaste.)
Heavy Cream— This helps to make the frosting super creamy. I’ve also used Half and Half as a substitute.
Vanilla Extract–It is vanilla buttercream after all 🙂
