What is Condensed Milk Buttercream?
Condensed milk buttercream, also known as Russian buttercream, is a frosting made with just butter and sweetened condensed milk. It has a smooth, creamy texture and a rich, slightly caramelized sweetness from the condensed milk. This buttercream is easy to make, doesn't require powdered sugar, and works well with Ferrero Rocher Condensed Milk Buttercream. It is perfect for spreading, piping, or filling cakes and pastries.
Why is there no Powdered Sugar added?
Powdered sugar isn't needed in condensed milk buttercream because sweetened condensed milk already provides enough sweetness and structure. The condensed milk has a thick, creamy consistency that combines with the butter to create a smooth frosting without the grainy texture powdered sugar can sometimes add. This makes the buttercream rich, silky, and perfectly sweetened without extra ingredients.
Ingredients Needed
- Unsalted Butter (500 g / 1.1 lbs) This forms the base of the buttercream, providing a rich, creamy texture. Using unsalted butter lets you control the flavor balance.
- Sweetened Condensed Milk (395 g / 14 oz) This replaces powdered sugar, adding sweetness and a smooth, creamy consistency to the frosting. It also gives the buttercream a slight caramel-like flavor.
- Ferrero Rocher Chocolates (6 pieces) These add the signature hazelnut and chocolate flavor, along with a touch of crunch from the finely blended nuts. They elevate the buttercream's taste with their luxurious blend of chocolate, hazelnut, and wafer.
- Warm Milk (80 ml / ⅓ cup) Warm milk helps soften the Ferrero Rocher chocolates, making them easier to blend smoothly into the buttercream. It also enhances the flavor and consistency of the frosting.

How To Make Ferrero Rocher Condensed Milk Buttercream
Whip the Butter. Start by whipping the softened butter in a mixing bowl until it's light and fluffy. This helps create a smooth and airy base for your frosting.
Add Condensed Milk. Gradually mix in the sweetened condensed milk. Whip it with the butter until fully combined, ensuring a creamy consistency.
Blend Ferrero Rochers with Warm Milk. Warm the milk slightly, then blend it with the Ferrero Rocher chocolates until smooth. Warming the milk helps melt the chocolates and release their flavors.
Combine the Mixtures. Add the blended Ferrero Rocher mixture to the butter and condensed milk base. Whip everything together until the buttercream is smooth and evenly flavored.
Release Air Bubbles. Mix the buttercream with a silicone spatula for about a minute to release any air bubbles and make it even smoother.
Store or Use. The buttercream is ready to use for piping, spreading, or filling desserts. If you're not using it right away, store it in an airtight container in the fridge or freezer.
