How to evaluate the Laplacian of a function as a function?

Hi, I have a stupid problem and cannot find a solution anywhere. I have the function func[x_,y_] := 3/Pi*(1 - x^2 + y^2))^2 which I need the Laplacian of: funcLapl := Laplacian[func[Xx,Yy]] The Laplacian is computed correctly, but how can I treat the result as a function? I want to be able to evaluate/plot the Laplacian. I tried many things and I'm frustrated. My current solution is to manually copy the derived Laplacian and create a function from that. It's obviously not a good solution. Any suggestions?
