Homemade Buttercream Frosting
Listen, if you’ve ever had a cake where the frosting completely overpowered the flavor, you already know how important a good buttercream is. This recipe is my go-to because it’s rich, smooth, and perfectly balanced — not overly sweet, just creamy and delicious in all the right ways.
This is the kind of frosting that complements your baked goods instead of stealing the show. Light, fluffy, and silky, it spreads beautifully over cakes and pipes perfectly onto cupcakes.
Whether you’re baking for a special occasion or just because, this buttercream always delivers.
I love how simple it is too. With just a handful of staple ingredients, you can create a bakery-style frosting right at home.
It’s reliable, easy to customize, and comes together in just a few minutes with a stand mixer.
Enjoy this buttery, sugary goodness with your vanilla cake, sugar cookies, chocolate cake, or pie.
Or with a spoon, right out of the bowl.
Ingredients You’ll Need
- Unsalted butter
- Powdered sugar
- Vanilla extract
- Salt
- Whole milk
Why These Ingredients Matter
- Butter – The base of the frosting, giving it richness and structure
- Powdered sugar – Sweetens and creates that smooth, classic buttercream texture
- Vanilla extract – Adds depth and a warm, bakery-style flavor
- Salt – Balances the sweetness so the frosting isn’t overpowering
- Milk – Helps loosen the frosting and creates a light, fluffy consistency
Tips for the Best Buttercream
- Make sure your butter is at room temperature — soft, but not melted
- Start mixing on low speed to avoid powdered sugar flying everywhere
- Use the paddle attachment for a smooth, less airy (but still fluffy) texture
- Don’t skip the salt — it’s key to keeping the frosting balanced
- Beat for a full 2–3 minutes at the end to get that light, fluffy finish
How Much Frosting This Makes
This recipe yields about 3 to 3½ cups of buttercream frosting, making it perfect for a variety of desserts. Here’s what you can expect:
- Frosts 12–18 cupcakes, depending on how generously you pipe
- Covers a 9×13 sheet cake with a smooth layer
- Frosts and fills a 2-layer 8-inch cake (with a thinner layer of frosting)
- Works well for a 3-layer 6-inch cake
- If you prefer thick, bakery-style swirls or extra filling between layers, consider making 1½ times the recipe to ensure you have enough.
