Ingredient Tips

Unsalted Butter

Room-temperature butter creates the fluffiest frosting. It should be soft enough to press with your finger but not melted.

Fresh Lemons

Fresh lemon juice and zest provide much better flavor than bottled lemon juice.

Powdered Sugar

Sift powdered sugar before mixing for an extra smooth frosting.

Heavy Cream

Heavy cream gives the frosting a luxurious, silky texture while making it easier to spread or pipe.

How to Make Lemon Buttercream Frosting

Step 1: Beat the Butter

Place softened butter into a large mixing bowl.

Beat using an electric mixer for about 3–5 minutes until pale, fluffy, and creamy.

Step 2: Add Powdered Sugar

Gradually add powdered sugar one cup at a time.

Mix on low speed first to prevent sugar from flying everywhere, then increase to medium speed.

Step 3: Add Lemon Flavor

Mix in:

• Fresh lemon juice
• Lemon zest
• Vanilla extract
• Salt

Beat until everything is fully combined.

Step 4: Adjust Consistency

Add heavy cream one tablespoon at a time.

Beat for another 2–3 minutes until the frosting becomes smooth, light, and airy.

If needed:

• Add more powdered sugar for thicker frosting.
• Add extra cream for softer frosting.

Step 5: Frost Your Desserts

Use immediately or store for later.

Spread with a spatula or pipe decorative swirls using your favorite piping tip.
