Ingredients and substitutes
Egg Whites: Whip up to form a stable meringue that provides structure and stability to the buttercream. Substitute with pasteurized egg whites from a carton if concerned about raw eggs. Granulated Sugar: Sweetens the buttercream and is used to make a sugar syrup that stabilizes the meringue. Can be substituted with other granulated sweeteners like caster sugar or superfine sugar. Unsalted Butter: Adds richness and flavor while giving the buttercream its smooth and creamy texture. Substitute with vegan butter for a dairy-free version. Vanilla Extract: Enhances the flavor of the buttercream. Substitute with other flavor extracts or pastes for different flavor profiles. Water: Used to make the sugar syrup. Can be substituted with other liquids for flavored variations, such as fruit juice or liqueur. Cream of tartar: Helps stabilize the meringue, making it easier to achieve stiff peaks. You can substitute an equal amount of white vinegar or lemon juice for cream of tartar. Use 1/2 teaspoon of vinegar or lemon juice for every 1/2 teaspoon of cream of tartar.
How to make Italian meringue buttercream
Prep: Measure out all your ingredients before you start. The egg whites should be in a clean, grease-free bowl.
Sugar Syrup: In a small saucepan, combine the sugar and water. Heat over medium-high heat, stirring until the sugar dissolves. Once the sugar is dissolved, stop stirring and let the syrup come to a boil. Use a candy thermometer to monitor the temperature.
Whip Egg Whites: While the sugar syrup is cooking, start whipping the egg whites with salt and cream of tartar on medium speed in a stand mixer with the whisk attachment. Whip until they reach soft peaks. Cook Sugar Syrup: Once the sugar syrup reaches 240°F (115°C), remove it from the heat. With the mixer running on low speed, carefully and slowly pour the syrup into the egg whites, aiming for the side of the bowl to avoid splattering. Be careful as the syrup is very hot. Whip Meringue: Increase the mixer speed to medium-high and whip the meringue until it becomes thick and glossy, and the bowl is cool to the touch, about 10-15 minutes.
Add Butter: With the mixer running on medium speed, add the butter one cube at a time, allowing each cube to incorporate before adding the next. The mixture may look curdled at this point, but keep mixing until it becomes smooth and creamy. Add Flavoring: Once all the butter is incorporated, add the vanilla extract and mix until combined. Adjust Consistency: If the buttercream is too soft, refrigerate it for 15-30 minutes, then re-whip to achieve the desired consistency. Use or Store: Use the buttercream immediately, or store it in an airtight container in the refrigerator for up to a week. Before using, let it come to room temperature and re-whip to restore its creamy texture. Enjoy: Use the Italian Meringue Buttercream to frost your cakes or cupcakes. It’s deliciously smooth and perfect for any occasion!
Tips for success
Clean Equipment: Make sure all your equipment, including bowls and beaters, are clean and free of grease, as any residue can prevent the egg whites from whipping properly. Room Temperature Ingredients: Bring your egg whites and butter to room temperature before starting. Cold ingredients can result in a curdled buttercream. Stable Meringue: Whip the egg whites until they form stiff peaks before adding the sugar syrup. This will create a stable meringue that holds its shape. Slow Sugar Syrup Addition: When adding the hot sugar syrup to the egg whites, pour it in a slow, steady stream down the side of the bowl to avoid cooking the egg whites. Cool Meringue: Ensure the meringue is completely cool before adding the butter. Warm meringue can melt the butter and result in a soupy mixture. Gradual Butter Incorporation: Add the butter to the meringue gradually, allowing each piece to fully incorporate before adding more. This will help prevent the buttercream from curdling. Refrigeration: If the buttercream is too soft after adding all the butter, refrigerate it for 15-30 minutes, then re-whip until smooth. Flavor Variations: Experiment with different flavor extracts, pastes, or essences to create unique flavor profiles. Storage: Store any leftover buttercream in an airtight container in the refrigerator for up to a week. Let it come to room temperature and re-whip before using.
Troubleshooting
Curdled Buttercream: If your buttercream looks curdled after adding the butter, it may be because the butter was too cold or the meringue was too warm. To fix this, let the mixture sit at room temperature for about 30 minutes, then re-whip it until smooth. Runny Buttercream: If your buttercream is too runny, it may be because the butter was too warm or the meringue was too soft. Place the bowl in the refrigerator for about 15-30 minutes, then re-whip it until it reaches the desired consistency. Grainy Buttercream: If your buttercream is grainy, it may be because the sugar syrup was not fully dissolved or the butter was added too quickly. Make sure the sugar syrup is fully dissolved before adding it to the meringue, and add the butter slowly, allowing each piece to fully incorporate before adding more. Lumpy Buttercream: If your buttercream is lumpy, it may be because the butter was too cold or the meringue was too stiff. Make sure the butter is at room temperature before adding it to the meringue, and whip the mixture until it becomes smooth and creamy. Air Bubbles: If your buttercream has air bubbles, it may be because the meringue was over-whipped. To fix this, gently fold the buttercream with a spatula to remove the air bubbles. Oily Buttercream: If your buttercream is oily, it may be because the butter was not fully incorporated. Make sure to whip the buttercream until it becomes smooth and creamy.
