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 🙂

Not my favorite, has a funky taste and aftertaste. Made to take to an event with keto cream cheese cookies, maybe next time with a different sweetener.

Can you use liquid allulose in this? And if so, how much? Thanks!

I used 1 cup of powdered Swerve instead and it turned out great!

I only have Swerve and I don't like things overly sweet. Is there something I can add to cut the sweet taste or should I just use less swerve? Thanks!

I would just start adding the Swerve in slowly. Mix and taste until you get to your preferred sweetness. Also, make sure you're using powdered Swerve, otherwise the frosting will end up very grainy. If you only have granular Swerve, you can pop it into a coffee grinder to powder it quickly. Hope it turns out delicious!

The texture was perfect but way too sweet. I used powdered serve. It was all I had

@Melissa Fromm,Thank you for your comment it saved me. I added slowly and stopped at a cup because it was sweet enough by that point. Great recipe, but I can't imagine 2 cups of sweetener.

Well, the problem is you substituted Swerve for the Allulose. Allulose is 70% as sweet as sugar, Swerve is slightly sweeter than sugar. Try using the Allulose.

It's icing, made of mostly sugar, it supposed to be sweet...how would it be anything but sweet?
