Ingredients:
1 cup unsalted butter, softened
2 cups powdered erythritol or powdered sweetener of choice
1 teaspoon vanilla extract
2-4 tablespoons heavy cream or coconut cream
Pinch of salt
Instructions:
Softened Butter:

Make sure the butter is softened to room temperature. This is crucial for achieving a smooth and creamy texture.
Cream the Butter:

In a mixing bowl, beat the softened butter with an electric mixer on medium-high speed until it becomes pale and fluffy. This usually takes about 2-3 minutes.
Add Sweetener:

Gradually add the powdered erythritol or your sweetener of choice to the whipped butter. Continue to beat until well combined and smooth. Adjust the sweetness to your liking.
Add Vanilla Extract:

Add the vanilla extract and a pinch of salt to the mixture. Beat again until everything is well incorporated.
Adjust Consistency:

Depending on your desired consistency, add heavy cream or coconut cream, one tablespoon at a time, while continuing to beat the mixture. Stop when you reach the desired thickness. Be cautious not to add too much liquid at once.
Beat Until Fluffy:

Beat the frosting for an additional 2-3 minutes on medium-high speed to make it light and fluffy.
Taste and Adjust:

Taste the frosting and adjust the sweetness or flavor if needed. You can add more sweetener or vanilla extract according to your preference.
