In a blender, add the pumpkin, heavy cream, half and half, sugar and pumpkin spice.
Blend the mix until it is smooth. We found that blending the mix for at least a minute, gave us a nice texture.
Pour the ice cream mix into a freezer safe container and place into the freezer.
Allow to freeze for 2-4 hours, overnight is best.
Scoop and enjoy. This homemade ice cream may get firmer than store ice cream. You will want to let it set out for 10 minutes to serve if eating several days later.
