Preheat the oven to 350 degrees.
In a large bowl, stir the almond butter and the pumpkin puree to blend. Add the eggs, honey and maple syrup and whisk to combine. Then sprinkle in the pumpkin spice, salt, baking soda and vanilla and stir well. If using nuts, add them in now and toss to combine.
Grease an 8x8 baking dish with a teaspoon of coconut oil or butter and, using your fingers, coat the dish thoroughly. Now pour the batter in and bake 30 minutes.
Cool and serve. Serve with whipped cream, ice cream or alongside a cup of tea or coffee or as a healthy breakfast. Refrigerate any leftovers.
