Butter and Hot Fudge Notes

This recipe uses a larger amount of butter to create structure and stability. The buttercream can be halved easily and will frost up to 36 cupcakes when piped with a rosette tip.

Hot fudge sauce adds chocolate depth and helps the buttercream pipe with clean definition. Homemade or store bought hot fudge sauce both work well, as long as the sauce is fully cooled before mixing.

Ingredients in Chocolate Condensed Milk Buttercream (Hot Fudge Version)

Unsalted butter: This forms the base of the buttercream and gives structure. Softened butter blends smoothly and helps the frosting whip evenly.
Sweetened condensed milk: This replaces powdered sugar and creates a smooth, creamy texture without grit. It also adds gentle sweetness and keeps the buttercream soft.
Hot fudge sauce: This provides deep chocolate flavor and improves piping consistency. Homemade or store bought both work well, as long as the sauce is fully cooled.

How To Make Hot Fudge Chocolate Condensed Milk Buttercream

Step 1: Cream the butter
Beat the softened butter for 2 to 3 minutes until smooth and pale. The butter should look creamy and evenly whipped before adding anything else.

Step 2: Add the condensed milk
Pour in the sweetened condensed milk and beat for 1 to 2 minutes until fully combined. The mixture should look smooth and slightly glossy.

My Top Tip

If the buttercream looks slightly separated during mixing, stay calm. This can happen as the ingredients combine.

Place the bowl in the fridge for about 20 minutes. Bring it back to room temperature, then beat again at medium high speed. The buttercream will smooth out and return to a creamy, pipeable texture.

How I Use This Chocolate Condensed Milk Buttercream

I use this chocolate condensed milk buttercream on cakes, cupcakes, and layered desserts that need clean structure. The texture holds well for piping borders, ruffles, and swirls.

It spreads smoothly over cake layers and works well between tiers without slipping. I also use it as a filling for sandwich style desserts where a soft but stable chocolate buttercream is needed.

Because it contains no powdered sugar, the finish stays smooth and creamy without drying out.
