If you have a lot of flowers to make out of buttercream, can you make them ahead of time and freeze them? TIA

Why not make them ahead of time and air dry them? That way you don't have to work quickly to get them on the cake before they thaw.

Definitely air drying is better.

To have your flowers dry do you need to use a certain buttercream recipe. Mine never dry that hard to transfer?
Thanks

If you're talking about roses, as long as it's stiff enough to hold the shape while you're making them, they'll air dry just the same. It may take 2-4 days to dry enough to pick them up without easily breaking off the outer petals.

Air dry, definitely. While they may be crusted on the outside, they are nice and soft and edible on the inside.

How long depends on the recipe. I liked to make mine the night before but I could make them in the morning and put them on the cake in the afternoon.

My regular all crisco buttercream will air dry just fine so I don't feel the need to make a special recipe for it, though I have seen some.

You just want to make sure they sit out, you can lightly cover them with a paper towel, but you can't close them up in a container or cover tightly in plastic wrap. They need the air to dry out.

They aren't going to be rock hard, like royal icing flowers, but usually hard enough to gently pick up and place on a cake.
