Essential Ingredient Notes for Your Perfect Vegan Lemon Frosting

Creating truly spectacular vegan lemon frosting starts with selecting the right ingredients. Each component plays a crucial role in achieving that creamy texture and vibrant lemon flavor:

  • Fresh Lemon (Whole): This recipe calls for one full lemon, utilizing both its freshly squeezed lemon juice and bright lemon zest. The zest is particularly important as it carries the most potent and aromatic lemon oils, providing a depth of flavor that juice alone cannot achieve. While bottled lemon juice or jarred zest might seem convenient, they will significantly diminish the overall freshness and intensity of the lemon flavor. Always opt for fresh for the best results!
  • Cold Vegan Butter: You’ll need 1/2 cup of high-quality vegan butter. Brands like Earth Balance buttery sticks are excellent choices due to their consistent texture and neutral flavor profile that won’t overpower the lemon. Using cold butter is key; it helps the frosting achieve a stable, fluffy consistency when beaten, preventing it from becoming too soft or greasy.
  • Powdered Sugar (Confectioner’s Sugar): This is the backbone of any buttercream. You’ll require approximately 2 1/2 to 3 cups of powdered sugar. This type of sugar dissolves smoothly into the frosting, creating a silky texture without any grittiness. Having a little extra on hand is always wise for adjusting consistency.
  • Cold Full-Fat Canned Coconut Milk: This ingredient is essential for adding richness and creaminess without dairy. The crucial part here is using the solid, thick cream that separates and rises to the top of a refrigerated can of full-fat coconut milk. Simply chill a can overnight, open it, and scoop out only the firm, white portion. Avoid shaking the can before chilling, as this will reintegrate the cream with the liquid, making it harder to separate. You’ll use 2-3 tablespoons, adjusting based on your desired consistency.

Crafting Your Vegan Lemon Frosting: A Step-by-Step Guide

Making this dairy-free lemon frosting is straightforward and incredibly rewarding. Follow these steps carefully to achieve a light, fluffy, and perfectly pipeable buttercream:

Fresh lemon zest is key to an aromatic and flavorful frosting.

STEP 1: Prepare Your Lemon and Combine Initial Ingredients.
Begin by zesting your lemon directly into a large mixing bowl, then juice it, adding the fresh lemon juice to the same bowl. Aim for about 1 teaspoon of juice and 1/2 teaspoon of zest, though the specific amount may vary slightly depending on your lemon’s size. Next, add 2 1/2 cups of your powdered sugar, 2 tablespoons of the solid part of cold coconut milk, and the cold vegan butter to the bowl. It’s important to reserve 1/2 cup of powdered sugar and 1 tablespoon of coconut milk for later adjustments. This ensures you have control over the final consistency of your frosting.

STEP 2: Beat to Perfection.
Using an electric hand mixer, begin beating all the ingredients together. Start on a low speed to incorporate the powdered sugar slowly and prevent it from flying out of the bowl. Once the sugar is mostly incorporated, gradually increase the speed to medium-high. Continue beating until the mixture is fully blended, light, and wonderfully creamy. Be careful not to over-mix, as this can incorporate too much air, leading to a less stable frosting, especially with vegan butters.

STEP 3: Achieve the Ideal Consistency.
Now it’s time to fine-tune your frosting. If it appears too thin, gradually add the reserved powdered sugar, a tablespoon at a time, beating after each addition until the desired thickness is reached. Conversely, if your frosting is too thick or stiff, gently thin it out by adding the reserved 1 tablespoon of coconut milk, a tiny bit at a time, until it reaches a spreadable or pipeable consistency. The goal is a frosting that is stiff enough to hold its shape beautifully when piped, yet still smooth and easy to work with.

STEP 4: Frost Your Treats!
Your delicious vegan lemon frosting is now ready to use! You can use it immediately to frost a cake, spreading it evenly with an offset spatula. If your plan is to pipe the frosting onto cupcakes or create more intricate designs, I highly recommend placing the dairy-free lemon buttercream in the refrigerator for about 5-15 minutes. This brief chill time will allow it to stiffen slightly, which will significantly help it hold its shape and definition when piped, resulting in much cleaner and more professional-looking decorations.

PRO TIP: When working with any buttercream, especially vegan versions that can be more sensitive to temperature, try to handle the piping bag as little as possible with warm hands. Work quickly to avoid “melting” your frosting, which can cause it to lose its firm texture and make piping difficult. If it starts to get too soft, pop it back into the fridge for a few minutes.

Storing and Freezing Your Vegan Lemon Frosting

Have leftover frosting? No problem! This vegan lemon buttercream stores exceptionally well, allowing you to prepare it in advance or enjoy it for later. Store any remaining frosting in an airtight container in the refrigerator for up to a week. For longer storage, it can be frozen for up to 3 months. When you’re ready to use it, simply let it thaw completely in the fridge. Once thawed, give it a good re-whip with your electric mixer to bring it back to its original smooth, fluffy consistency. This will help reincorporate any separated ingredients and restore its perfect texture for spreading or piping.

Equipment

  • 1 Large Bowl
  • 1 electric mixer
  • 1 microplane citrus zester
  • 1 Citrus Juicer

Ingredients

  

  • 1/2 cup vegan butter
  • 1 tsp fresh lemon juice
  • 1/2 tsp fresh lemon zest
  • 3 cups powdered sugar (2 1/2 to 3 cups)
  • 3 Tbsp cold canned coconut milk (2-3 Tbsp; use only the solid, top part of a refrigerated can)

Instructions

 

  • Zest your lemon, then juice it. Measure out 1 tsp of juice and 1/2 tsp of zest.
  • Into a large bowl, combine 2 1/2 cups of powdered sugar, 2 Tbsp of the solid, cold coconut milk, and all other ingredients (vegan butter, lemon juice, lemon zest). Keep 1/2 cup of powdered sugar and 1 Tbsp coconut milk in reserve.
  • Using an electric hand mixer, begin beating the ingredients on low speed to avoid a mess, then gradually increase to medium-high. Beat until the mixture is fully blended, light, and creamy, being careful not to over-mix.
  • Adjust the consistency: if too thin, add reserved powdered sugar a tablespoon at a time until thick enough. If too thick, thin with the reserved 1 Tbsp of coconut milk, adding slowly. You want the frosting to be stiff enough to hold a shape when piped.
  • Use immediately for cakes. For piping onto cupcakes, refrigerate the frosting for 5-15 minutes to stiffen it slightly, which helps it hold its shape better.
