1. Prepare the Butter:

• Start by making sure the butter is softened to room temperature. This is crucial for creating a smooth and fluffy frosting.

2. Beat the Butter:

• Using a stand mixer or hand mixer, beat the softened butter on medium speed for about 2-3 minutes, or until the butter becomes light and fluffy.

3. Add the Sweetened Condensed Milk:

• Gradually add the sweetened condensed milk to the butter while continuing to beat the mixture. Beat on medium-high speed until the frosting becomes fluffy and smooth.

4. Optional Flavoring:

• If you want to add extra flavor, mix in the vanilla extract and a pinch of salt. The vanilla enhances the flavor, while the salt helps to balance the sweetness.

5. Continue Mixing:

• Beat the mixture for an additional 2-3 minutes, ensuring it is fully combined and has a light, airy texture. You want the buttercream to be spreadable but still stiff enough to hold its shape when piped.

6. Use or Store:

• Once the buttercream is smooth and fluffy, it’s ready to use. You can frost cakes, cupcakes, or other desserts with it.

• If you’re not using it immediately, store the buttercream in an airtight container at room temperature for up to 2 days or in the refrigerator for up to a week. If refrigerated, bring it back to room temperature and re-whip it before using.
