To spice it up you can add ¼ teaspoon ground nutmeg, ¼ teaspoon ground ginger, and ⅛ ground cloves.Pumpkin seed butter, cashew butter, or peanut butter can be used to sub for almond butter, but they will change the flavor a bit.Some have noted that their batter is runny. You can start with ¼ cup of pumpkin puree and if the batter is too thick add a bit more, but no more than the ½ cup that the recipe calls for. Another option is to add some coconut flour to the batter to thicken it (see comments). Another way to thicken the batter and reduce the sweetness a bit is to bring down the sweetener by one or two tablespoons. It's still sweet enough but I wouldn't go beyond that.
