Kitchen Equipment Needed
- Electric mixer (stand or hand mixer)
- Mixing bowls
- Spatula
- Measuring cups and spoons
- Piping bags (optional for decoration)
- Rubber spatula or offset spatula for spreading
Ingredients Overview
- Butter: The main ingredient that creates the creamy base for the frosting.
- Sweetened Condensed Milk: Adds sweetness and richness, creating a smooth, velvety texture.
- Vanilla Extract: For a hint of flavor that complements the richness of the butter and condensed milk.
- Powdered Sugar: To achieve the perfect consistency and sweetness level for frosting.
Ingredients
- 1 cup (2 sticks) unsalted butter, softened
- 1 can (14 oz) sweetened condensed milk
- 2 teaspoons vanilla extract
- 1 1/2 to 2 cups powdered sugar (adjust to desired thickness)
Step-by-Step Instructions
- Prepare the Butter: Place the softened butter in a large mixing bowl. Beat it with an electric mixer on medium speed for about 2-3 minutes, or until it becomes light and fluffy.
- Add Sweetened Condensed Milk: Gradually add the sweetened condensed milk to the butter, mixing continuously. Continue beating on medium speed until fully incorporated and smooth.
- Flavor with Vanilla: Add the vanilla extract to the mixture and beat until combined.
- Add Powdered Sugar: Gradually add powdered sugar, 1/4 cup at a time, until the frosting reaches your desired consistency. If you prefer a thicker frosting for piping, you can add more powdered sugar. For a softer, spreadable frosting, you can use less.
- Beat Until Smooth: Continue beating for an additional 2-3 minutes on high speed to achieve a silky, smooth texture.
- Use or Store: Use the frosting immediately or store it in an airtight container at room temperature for up to 2 days. If you plan to store it longer, refrigerate and let it come to room temperature before using.
Recipe Tips
- Room Temperature Butter: Make sure your butter is softened to room temperature to avoid lumps and to achieve a smooth, airy texture.
- Adjusting Sweetness: If you prefer a less sweet frosting, you can adjust the amount of powdered sugar added. For a sweeter frosting, feel free to add more.
- Consistency: If the frosting is too thick, you can add a tablespoon of heavy cream or milk to loosen it. If it’s too thin, add a little more powdered sugar until it thickens to your liking.
- Flavor Variations: You can easily customize this frosting by adding different extracts like almond, lemon, or hazelnut for a unique twist.
