Ingredients and Substitutions

This buttercream uses a few simple, versatile ingredients that you can adapt to suit your dietary needs and flavour preferences:

Plant Based Butter, Icing Sugar, Vegetable Shortening, Salt, Water and Clear Vanilla Extract in bowls to make Vegan Stable Vanilla Buttercream.

Plant-Based Butter or Shortening: The base of your buttercream. A 50/50 mix gives the ideal balance of flavour and stability. For richer flavour, increase the butter portion, but note it may soften more in warm conditions.
Icing Sugar: Provides sweetness and structure. Sift it for a smooth, lump-free buttercream. For refined sugar-free options, powdered sugar substitutes can be used, though texture may vary slightly.
Plant-Based Milk or Water: Adds moisture for a creamy, pipeable consistency. Almond, soy, or oat milk work well. Water can be used for a lighter, colour-neutral option.
Vanilla Extract: Use clear vanilla extract to keep the buttercream bright white. Regular vanilla and vanilla bean paste work too and give a slightly creamier hue. You can experiment with other extracts like almond or maple.
Salt: A pinch balances sweetness and enhances flavour.

Tip for Substitutions: This recipe is naturally vegan and dairy-free, and it’s adaptable for allergy-friendly variations. For a richer flavour, increase the plant-based butter portion, while for extra stability – especially useful in humid kitchens or when transporting cakes – you can use all shortening. You can also experiment with different plant-based milks and flavour extracts to create your own unique twists.

How to Make Stable Vanilla Buttercream

Before you begin, gather all your ingredients and ensure that both the plant-based butter and the liquid (plant-based milk or water) are at room temperature. This will help the buttercream come together smoothly and achieve the perfect light, fluffy consistency.

Soften the Butter: Add plant-based butter or shortening to a mixing bowl. Beat with a paddle attachment for 1–2 minutes until softened. This step ensures a smooth, creamy base.
Add Icing Sugar Gradually: Slowly add icing sugar in small batches to prevent it from flying out of the bowl. Mix until incorporated. Gradual addition ensures a smooth texture without lumps.
Add Liquid & Flavourings: Mix in plant-based milk or water, remaining icing sugar, vanilla extract, and a pinch of salt. This step balances flavour and texture.
Final Mix: Scrape down the sides of the bowl and continue mixing for 1–2 minutes until light, fluffy, and smooth.
Optional Colouring: Your buttercream is now ready to colour or pipe immediately. For a bright white base, use clear vanilla extract and avoid darker liquid extracts.

Piping Tips for Perfect Buttercream

This stable vegan vanilla buttercream is ideal for piping thanks to its slightly crusting texture and medium consistency. Here are some tips to get the best results:

Create Flowers and Two-Tone Designs: The slightly crusting texture allows you to pipe detailed floral patterns and two-tone swirls that hold their shape beautifully. Try using multiple colours in the same piping bag for a stunning ombré or rainbow effect.
Experiment with Piping Tips: Different piping tips produce different effects. Use rosette tips for elegant swirls, star tips for classic cupcake finishes, and shell tips for borders and accents. Combining tips can give your baked creations a professional, bakery-quality look.
Control Softness: If your buttercream becomes too soft while piping, don’t worry! Simply refrigerate for 10–15 minutes to firm it up, then re-whip briefly to restore a smooth, pipeable consistency.
Practice Pressure and Angle: For consistent results, maintain even pressure on the piping bag and hold it at the correct angle for the design you want. Practising on a parchment sheet before decorating your cake or cupcakes can help.
Keep It Fresh: Work in a cool environment when possible, especially in warmer kitchens. This ensures the buttercream keeps its shape and doesn’t melt while piping.

By following these tips, you can confidently pipe everything from cupcakes and cake borders to intricate flowers and layered designs, making your creations look professional and polished.

Common Buttercream Questions

Can I use this buttercream in humid weather?

Yes! Its medium consistency holds up well even in warm or humid kitchens.

Can I pipe flowers or two-tone designs with it?

Absolutely. The slightly crusting texture makes it ideal for detailed piping and creating patterns that hold their shape.

Is this recipe suitable for macarons?

Yes, it works beautifully as a filling for macarons and layered desserts.

Can I make it ahead of time?

Yes! Store in the fridge or freezer (see storage tips). Bring to room temperature and re-whip before using.

Can I flavour it differently?

Definitely! Try adding cocoa powder for a chocolate version or a few drops of fruit extract or jam for unique flavour twists. I adore turning this into strawberry buttercream in the Summer by adding a few teaspoons of my homemade strawberry jam.

What if my buttercream is too soft or too stiff?

If too soft, refrigerate for 10–15 minutes and re-whip before piping. If too stiff, add a teaspoon of plant-based milk at a time until you reach the desired consistency.

Store in an airtight container in the refrigerator for up to 1 week.
Bring to room temperature and re-whip before using for best results.
For longer storage, freeze for up to 3 months; thaw in the fridge overnight and re-whip before piping.

Extra Tip: If your buttercream separates slightly in the fridge, simply let it come to room temperature and beat for 1–2 minutes to restore a smooth texture.
