This Dulce de Leche Buttercream is smooth and creamy without using powdered sugar. It boasts a rich caramel flavor and velvety texture. The buttercream holds its shape beautifully and is stable for decorating.
Beat the Butter: Add unsalted butter to a bowl and mix for up to 5 minutes, or until light and fluffy.
Incorporate the Dulce de Leche: Add the dulce de leche and mix again for several minutes until fully incorporated and silky smooth. If the mixture appears curdled, keep mixing—it will come together nicely.
Eliminate Air Bubbles: Use a silicone spatula to massage and mix the buttercream for a minute or two to knock out any big air bubbles that may have formed.
