What is Honeycomb?
Honeycomb is a sweet, crunchy treat made from sugar, water, and baking soda. When heated, the baking soda causes the mixture to foam and expand, creating a light, airy texture with many tiny holes, resembling a honeycomb. It can be enjoyed plain or coated in chocolate, and it's often used in recipes like honeycomb buttercream for added flavor and texture.
Ingredients in No Grit Honeycomb Buttercream

- Boiling Water (80mL / ⅓ cup): Helps dissolve the powdered sugar to create a smooth syrup for the buttercream.
- Powdered Sugar (250-500g / 2-4 cups): Sweetens the buttercream and provides structure. Start with 250g and add more if needed for desired consistency and sweetness.
- Vanilla Extract (2 Teaspoons): Adds a rich, aromatic flavor to the buttercream.
- Unsalted Butter (500g / 1.1 lbs): Forms the base of the buttercream, giving it a rich and creamy texture.
- Honeycomb (150g / 5.3 oz): Adds a subtle honeycomb flavor and a unique texture with tiny crunchy flecks. Can be plain or chocolate-coated.

How To Make Honeycomb Buttercream
Grinding the Honeycomb
Start by placing the honeycomb in a bowl of a stick blender or food processor. Blend it until it becomes a fine powder. The finer the grind, the smoother your buttercream will be.

Mixing the Sugar and Water
In a bowl, combine the powdered sugar, boiling water, and vanilla extract. Mix well until the powdered sugar is fully dissolved. Strain the mixture through a fine mesh strainer to remove any undissolved lumps. Allow the mixture to cool completely before using.


Beating the Butter
In a mixing bowl, beat the softened unsalted butter until it becomes light and fluffy. This process will take a few minutes. You can use a stand mixer with a paddle attachment or a hand mixer for this step. Be sure to scrape down the sides of the bowl occasionally.

Combining the Mixtures
With the mixer running on medium speed, slowly add the cooled powdered sugar mixture to the beaten butter. Continue mixing for about 10 minutes. This will help ensure a smooth and consistent texture.

Adding the Honeycomb
Gradually add the powdered honeycomb to the buttercream mixture. Mix for an additional 2-5 minutes, scraping down the sides of the bowl occasionally. The result should be a smooth, silky honeycomb buttercream with tiny flecks of honeycomb throughout.

Storing and Using the Honeycomb Buttercream
Use the honeycomb buttercream immediately, or store it in the refrigerator for up to one week or in the freezer for up to two months. If stored, bring the honeycomb buttercream back to room temperature and re-whip it before using to restore its smooth texture.

Holly says
This frosting literally taste like ice cream, so easy to make and pipes like a dream. Instead of the honeycomb candy I substitute 2 tablespoons of pure honey and used this on my honey cinnamon sugar cookies. I also added two tablespoons of meringue powder for extra stability. Amazing dangerously delicious. I had some questions and Fay responded right away. Thank you Fay. Your frostings are delicious and easy to make
