About how many cupcakes do you think I can cover with a recipe of buttercream using the 2D tip?

And can you half a buttercream recipe?

Thanks so much for any help or input.

You should be able to half your buttercream recipe.

How many cups does your buttercream recipe yield? That will give us an idea of how many cupcakes you can frost.

I can cover 2 dozen cupcakes with a recipe of buttercream using 4lbs of powder sugar. There is usually some left over. It does depend on if your swirl is flat or full/taller.

I cover two dozen with a batch of Indydebi's buttercream. Make the swirls start a tiny ways in from the edge of the cupcake and you use half as much frosting but it still looks the same. They don't end up as top-heavy that way either.
