Ingredients

Scale

Buttercream Ingredients

  • 1 cup (2 sticks) unsalted butter, room temperature (226g)
  • 1 tsp vanilla extract or vanilla bean paste (5ml)
  • ¼ tsp fine salt (1g)
  • 14 oz can sweetened condensed milk (396g)
  • Powdered sugar (optional, for thickening, add in ½ cup increments)

Instructions

  1. Whip Butter: Using a stand mixer with a whisk attachment or a hand mixer, whip 1 cup of room temperature unsalted butter on medium-high speed for 5-7 minutes until it lightens in color and becomes fluffy by incorporating air.
  2. Add Vanilla and Salt: Add 1 teaspoon of vanilla extract and ¼ teaspoon of fine salt to the whipped butter, mixing on low speed until fully combined.
  3. Incorporate Sweetened Condensed Milk: Slowly add the 14 oz can of sweetened condensed milk in ¼ increments, mixing on medium speed after each addition. Scrape down the bowl continuously to avoid any pooling of milk at the bottom.
  4. Adjust Consistency (Optional): If the buttercream appears broken or too soft, gradually add powdered sugar in ½ cup amounts to thicken and bring the frosting together.
  5. Use or Store: The Russian buttercream can be used immediately to frost layer cakes, pipe on cupcakes, or ice cookies. It’s delicious and versatile on many desserts.

Notes

  • Use room temperature butter to ensure smooth whipping and incorporation.
  • Scrape the bowl frequently while mixing to prevent the condensed milk from settling.
  • Adjust powdered sugar as needed to achieve desired frosting thickness.
  • This frosting is rich and sweet but not overwhelmingly so due to butter’s creaminess balancing the condensed milk.
  • Store leftover buttercream in an airtight container in the fridge and bring to room temperature before re-whipping for best texture.
