Bake the Angel Food Cake as directed. Or you can use a store bought cake if desired.

Slice the baked Angel Food Cake into three horizontal layers.

Spread about 1/2 of the can of lemon pie filling over the lower two layers and top with the last layer of cake.

Add the water and unflavored gelatin to a small microwave safe bowl. Allow it to sit together for a minute or two.

Microwave this mixture for just a few seconds. Stir the mixture and then set it aside to cool.

In the bowl of a stand mixer (with the whisk attachment) or if you are using a hand mixer, add the heavy whipping cream, powdered sugar and vanilla. 

Whip the mixture until it thickens and soft peaks form.

Turn the mixer to a low speed and slowly pour the gelatin mixture into the whipped cream.

Increase the mixer speed to medium high and continue mixing until stiff peaks form.

Frost the outside with the whipped cream.
