🧁 Ingredients
| Ingredient | Quantity | Purpose |
|---|---|---|
| Unsalted Butter | 1 cup (room temperature) | Base for richness and creamy texture |
| Powdered Sugar | 4-5 cups | Sweetness and structure |
| Fresh Lemon Juice | 2-3 tbsp | Main source of tangy citrus flavor |
| Lemon Zest | 1 tbsp | Adds bold lemon essence |
| Heavy Cream or Milk | 1-2 tbsp | Helps reach spreadable/pipable consistency |
| Vanilla Extract | 1 tsp (optional) | Adds a warm background flavor |
🥄 Instructions
1. Cream the Butter
In a stand mixer, beat the softened butter on medium speed for 2-3 minutes until it’s pale and fluffy. This step is key for a smooth, airy frosting.
2. Add the Powdered Sugar
Gradually add powdered sugar (start with 4 cups), mixing on low to prevent a sugar cloud. Once incorporated, beat on medium-high for 2 minutes.
3. Add Lemon Juice and Zest
Mix in 2 tbsp of lemon juice and 1 tbsp of zest. For a bolder lemon taste, add another tablespoon of juice. Stir until evenly distributed.
4. Adjust the Consistency
Too thick? Add heavy cream (1 tbsp at a time). Too thin? Add extra powdered sugar. Aim for a smooth yet firm texture perfect for piping or spreading.
5. Final Whip
Give it a final beat on high for 1 minute to make it ultra fluffy. And there you go—perfect lemon buttercream frosting!
