Achieving perfect cake decorating starts with the right foundation, and this buttercream delivers a smooth, stable texture ideal for piping and detailing.
This professional-grade recipe uses simple ingredients with precise ratios to create a light, creamy frosting that holds its shape without being overly sweet.
Ingredients for Wilton Class Buttercream
Nine professional-grade ingredients combine for ultra-smooth, decorating-ready buttercream with perfect stability.
| Ingredient | Amount | Notes |
|---|---|---|
| Vegetable Shortening 🧈 | 1 cup | Solid, white, high melting point |
| Unsalted Butter 🧈 | 1 cup | Room temperature, softened |
| Powdered Sugar 🍚 | 8 cups | Sifted for smooth texture |
| Whole Milk 🥛 | ½ cup | Room temperature preferred |
| Pure Vanilla Extract 🌿 | 2 tsp | High-quality for best flavor |
| Almond Extract 🌰 | ½ tsp | Optional for depth of flavor |
| Salt 🧂 | ½ tsp | Fine grain, balances sweetness |
| Merengue Powder 🥣 | 2 tbsp | Wilton brand recommended for stability |
| Clear Vanilla Extract 🌿 | 1 tsp | For pure white color option |
The vegetable shortening is non-negotiable for stability at room temperature—Crisco is the gold standard here. Unsalted butter allows precise control over salt content; Land O’Lakes or Kerrygold are reliable choices. Powdered sugar must be sifted to eliminate lumps, and Domino or C&H brands dissolve most cleanly. The meringue powder provides structure—Wilton’s own product is formulated specifically for their methods.
No meringue powder? Egg white powder works at a 1:1 ratio, though the stability may vary slightly. For a pure white frosting, use only shortening and omit butter, adding clear vanilla for flavor. The milk can be swapped for heavy cream for richer texture or water in a pinch, though the flavor will be less complex. Always use pure extracts—imitation vanilla lacks depth.
Buttercream keeps at room temperature for 2 days or refrigerated for 2 weeks. Bring to room temperature and re-whip before using. For long-term storage, freeze in airtight containers for up to 3 months. The texture remains best when used fresh, but frozen buttercream revives beautifully with a quick re-whip.

Step-by-Step Instructions for Wilton Class Buttercream
Master the professional technique that yields ultra-smooth, stable icing ideal for decorating.
Step 1: Cream the Fats to Ideal Consistency
In a stand mixer fitted with the paddle attachment, beat the 1 cup Vegetable Shortening and 1 cup Unsalted Butter on medium speed for 2-3 minutes until completely combined. The mixture should appear pale and slightly increased in volume.
Scrape down the bowl with a silicone spatula to ensure even incorporation. This step creates a stable base that prevents separation during the sugar addition. The shortening contributes structure while the butter adds flavor—this balance is critical for professional results.
Step 2: Gradually Incorporate the Powdered Sugar
With the mixer on low speed, add the 8 cups Powdered Sugar one cup at a time, allowing each addition to fully incorporate before adding more. This gradual approach prevents a powdered sugar cloud and ensures even distribution without clumping.
After each cup, pause briefly to scrape the bowl and check for dry pockets at the bottom. The mixture will appear dry and crumbly at this stage—that’s normal. Resist adding liquid too soon; the powdered sugar needs time to hydrate properly within the fat mixture.
Step 3: Emulsify with Liquid and Flavorings
In a small bowl, whisk together the 0.5 cup Whole Milk, 2 tsp Pure Vanilla Extract, 0.5 tsp Almond Extract, 0.5 tsp Salt, 2 tbsp Merengue Powder, and 1 tsp Clear Vanilla Extract until the merengue powder fully dissolves. This liquid mixture distributes the flavors evenly and activates the stabilizers.
With the mixer on low speed, slowly pour the liquid mixture down the side of the bowl in a thin stream. Once fully added, increase to medium-high speed and beat for 4-5 minutes until the buttercream becomes light, fluffy, and pale ivory in color. The merengue powder will create a stable emulsion that holds its shape for piping.
Step 4: Adjust Consistency and Test Stability
Check the consistency by lifting the paddle: the buttercream should hold a soft peak that gently flops over at the tip. If it’s too stiff, add additional milk 1 tablespoon at a time. If too soft, add more powdered sugar ¼ cup at a time.
To test stability, pipe a small rosette on parchment paper. It should hold its shape without slumping or developing a shiny surface. This professional-grade buttercream will maintain its form at room temperature for several hours, making it ideal for intricate decorating work. The merengue powder ensures it won’t weep or separate, even in warm conditions.
Pro Tips For Making Wilton Class Buttercream
- Cream the Shortening First: Beat the vegetable shortening alone for 2 minutes before adding butter—this builds a stable base that holds up better in warm kitchens.
- Sift the Sugar: Always sift your powdered sugar first, even if it looks fine straight from the bag. I learned this the hard way after finding tiny lumps in my otherwise smooth frosting.
- Use Room-Temperature Butter: Pull your butter out 1-2 hours before starting, or it’ll leave chunks in the mix. Sounds obvious, but I’ve rushed this and ruined a batch.
- Add Milk Slowly: Start with 2 tablespoons of milk, then add more by the teaspoon—this frosting goes from perfect to soupy fast.
