Homemade Vanilla Buttercream Frosting

I’ll be honest, I’ve never been a fan of store-bought frosting. It’s overly sweet, has a strange waxy aftertaste, and somehow manages to be both stiff and greasy at the same time. I have been making my own homemade vanilla buttercream frosting for years and it is so simple to make. It’s made with simple ingredients and tastes a thousand times better. Once you make it from scratch, you’ll never want to peel the plastic off a tub again.

This is the frosting I reach for when I want to make an everyday cake feel special and taste homemade. Whether you’re frosting cupcakes for a birthday or spreading it on a cake, this vanilla buttercream is smooth , fluffy, and always a crowd-pleaser.

And the best part? You probably already have everything you need in your pantry.

How to Make Homemade Vanilla Buttercream Frosting

Step 1: Cream the Butter and Sugar

In a large mixing bowl, beat the softened butter on medium speed for about 2–3 minutes until light and fluffy. This step is key to a smooth frosting.

Step 2: Add Powdered Sugar

Slowly add the powdered sugar, one cup at a time, mixing on low speed so it doesn’t fly everywhere. Scrape down the sides of the bowl as needed.

Step 3: Add Vanilla & Cream

Pour in the vanilla extract and 2 tablespoons of cream or milk. Beat on medium-high speed for another 2–3 minutes until fluffy.

Step 4: Adjust Consistency

If the frosting is too thick, add a little more cream (1 tablespoon at a time). If it’s too thin, add more powdered sugar. Taste and add a pinch of salt if desired.
