Finally a new buttercream recipe for those who are sensitive to chickpeas!
They say most inventions are born out of a necessity and this Aquaflaxa swiss meringue buttercream is a perfect example!
Some people have a sensitive reaction to chickpeas, so my Aquafaba Swiss Meringue Buttercream may not be the best option for them.
I created this buttercream variation using flax seed gel so everyone can have their cake and eat it too!
As you may already know, flax seeds when soaked in water create a goopy, gluey substance called mucilage.
It’s the same goopy, gooey stuff that binds our recipes when we use flax meal as an egg replacer in cakes and cookies.
By boiling the whole flax seeds in water and then reducing the liquid it will whip up to a meringue just like our good buddy aquafaba!
Let’s call this one, Aquaflaxa!
From Mikoyo Schinners cookbook Homemade Vegan Pantry, she makes this mucilage and basically just calls it Flax “whites” since they resemble egg whites so much
It’s pretty much a straight up substitution for aquafaba in your recipes.
The recreation of my famous Swiss Meringue Buttercream Icing using this magical flax gel is proof of that and another win for those who have to stay away from those beans!
- For the Flax "whites" 1cup whole flax seeds
- 9 cups water
- For the Buttercream: 1 cup granulated sugar (200g)
- Cream of tartar ¼ teaspoon
- Confectioner's Sugar 2 cups (240g)
- Vegan Butter 4 sticks (454g)
- Solid Vegetable Shortening 1½ cup (339g)
- Vanilla Extract 2 teaspoons (10ml)
- First prepare the flax "whites" by boiling the whole flax seed with the water.
- Reduce heat to a rolling simmer and let it reduce down to 1¾ - 1½ cups, this may take 20-30 minutes (or more) but it is important to get it reduced properly
- Strain the mucilage through a fine sieve and it will look just like raw egg whites, if it is too liquid (meaning you have alot more than 1½ cups of mucilage) you will need to return the goop and the seeds to a pot and reduce longer. *Note: It will thicken as it cools
- If the goop is "too goopy" and thick, you will return to the pot, heat again and add more water to get to the right consistency. * see video tutorial
- Once you have gotten to the desired consistency, discard the seeds or use them in your favorite whole grain bread recipes (or the crackerbread recipe in my new cookbook!)
- To make the buttercream : Add the granulated sugar to the hot mucilage and stir to help dissolve, then cool to cold
- Whip the cold mucilage/ sugar mixture on high speed with the cream of tartar until it is stiff and glossy like a meringue.
- Add the sifted confectioner's sugar and mix to combine
- Slowly add the softened vegan butter and shortening while mixing on high speed
- It may look as if your emulsion is starting to break but with high speed whipping it will eventually come together
- Add the vanilla extract last
- **another note on the flax "whites" if your first reduction of "goop" seems to be too thin, you can always reduce it down later by boiling it down again (without the seeds)
