Making buttercream using a blender
Can you make buttercream frosting in a blender? How to make buttercream without a mixer?
You can use a blender to make your frosting, it may not be as fluffy as beaten with mixer paddles, but it's absolutely feasible. Of course, forget about fancy stuff like the Swiss meringue buttercream - your trusty blender will cope with the basic butter, sugar and flavourings kind.
The only difficulty is the paddles: quite a bit of cream will cling to them and refuse to be scooped out. Also while blending, you'll have to scrape the sides of the blender every so often.
Make sure all the ingredients are at room temperature. First whizz the butter until fluffy, then carefully add half the icing sugar and give it a good whizz. Scrape the sides, add the rest of the sugar and blend again. Add flavourings and pulse several times to combine.
If you only need a small quantity of buttercream, you can make it in one of those miniature blenders/choppers.
