The cupcake is set against a bright white marbled background, and another similarly decorated cupcake is partially visible in the blurred background. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

  • 1 1/2 cups Danish Creamery European Style Unsalted Butter (softened at room temperature)
  • 1 cup Besti Powdered Monk Fruit Allulose Blend
  • 1 tsp Vanilla extract
  • 1/8 tsp Sea salt
  • 1 tbsp Heavy cream (adjust as needed)

Instructions

  1. Step 1: Using a hand mixer, cream the softened Danish Creamery Butter and Besti blend together for 2-3 minutes until fluffy and light yellow. Begin at low speed, then increase once the sweetener is incorporated.
  2. Step 2: Beat in the heavy cream, vanilla extract, and sea salt at low speed until combined.
  3. Step 3: Increase the mixer speed to high and beat for an additional 2-3 minutes to achieve the desired light and airy consistency.
  4. Step 4: If the frosting is too thick, add more heavy cream, one teaspoon at a time, beating after each addition until you reach the perfect texture.

Tips & Variations

  • For a different flavor, try adding 1-2 tablespoons of unsweetened cocoa powder to make a sugar-free chocolate version.
  • Ensure the butter is soft but not melted to get the best fluffy texture.
  • If you don’t have Besti Monk Fruit Allulose Blend, you can substitute with another powdered low-carb sweetener but expect slight changes in texture.

Storage

Store the frosting in an airtight container in the refrigerator for up to 1 week. Before using, let it come to room temperature and re-whip with a hand mixer to restore its fluffy texture. You can also freeze it for up to 3 months; thaw overnight in the fridge before re-whipping.

How to Serve

FAQs

Can I use regular granulated sweetener instead of powdered?

It’s best to use powdered sweetener for a smooth frosting texture. Granulated sweeteners may not dissolve well and can leave a gritty feel.

Will this frosting harden if left out?

This buttercream will soften at room temperature but should hold its shape if not exposed to heat. For best results, keep it cool, especially in warmer environments.

Ingredients

Scale

Frosting Ingredients

  • 1 1/2 cups Danish Creamery European Style Unsalted Butter (softened at room temperature)
  • 1 cup Besti Powdered Monk Fruit Allulose Blend
  • 1 tsp Vanilla extract
  • 1/8 tsp Sea salt
  • 1 tbsp Heavy cream (adjust as needed)

Instructions

  1. Cream Butter and Sweetener: Using a hand mixer, beat the softened Danish Creamery butter and Besti powdered monk fruit allulose blend together for 2-3 minutes. Begin mixing at low speed to incorporate the sweetener, then increase to medium or high speed until the mixture is fluffy and light yellow in color.
  2. Add Cream and Flavorings: At low speed, blend in the heavy cream, vanilla extract, and sea salt. This combines the ingredients without deflating the fluffy texture you achieved earlier.
  3. Whip to Desired Consistency: Increase the mixer speed to high and continue beating the frosting for 2-3 minutes. This step aerates the frosting, making it smooth and creamy with the ideal spreadable consistency.
  4. Adjust Thickness if Needed: If the frosting is too thick for your liking, add additional heavy cream one teaspoon at a time, beating well after each addition until you reach your preferred texture.

Notes

  • Use unsalted butter to control the salt level in your frosting.
  • Adjust heavy cream quantity depending on your desired frosting thickness.
  • This frosting keeps well refrigerated for up to a week and can be softened by bringing to room temperature and beating again.
  • Ensure butter is softened at room temperature for easier whipping and better texture.
  • Use powdered monk fruit blend to avoid grittiness and achieve a smooth frosting.
