Russian Zefir

If you’ve never tried zefir or Russian marshmallow, you are in for a real treat! This meringue marshmallow is like a little bite of heaven – so fluffy, soft and just melts in your mouth. This marshmallow recipe is different from its American cousin because it’s made with agar gelatin. This type of gelatin will set at room temperature, no refrigeration required, at it sets much quicker and firmer than regular gelatin. I have the one I use from Amazon linked below! When making zefir, make sure to follow the recipe very carefully for best results. The cooking times and measurements need to be accurate for the marshmallow to turn out well!

For my strawberry cake, I went with strawberry flavored zefir but it can be made in a large variety of flavors. My other favorites are peach and raspberry. Check out my other zefir cake below!

Strawberry Buttercream

Any strawberry cake recipe needs a strawberry buttercream to go with it! For this cake, I used a regular buttercream recipe and added strawberry emulsion. It’s a thicker type of concentrated extract that also has color. It’s my favorite option for adding the most berry flavor. You can also use regular strawberry extract or a few tablespoons of strawberry preserves. If you are using preserves, make sure to add them after you have the buttercream done. Whip the butter and sugar together first, then add the preserves and mix for about 20 seconds. Overmixing can cause the frosting to separate. If you don’t like buttercream, marshmallow cake would also work really well with my ‘Berry Whipped Cream Frosting’.
