*New* Spice Cake recipe

We invited some friends over for family movie night last night and celebrated Gail's 60th birthday with a homemade, gluten-free, dairy-free spice cake.
I hadn't yet found a tried and true spice cake recipe, so I took my chances to adapt a regular spice cake recipe to meet our requirements.
It turned out well. I heard comments like "Ohhhh, this is the best!" and "This is what I want on my birthday!" so I've posted it in the Gluten Free Living tab.
