Combine almond flour, coconut flour, baking soda, sea salt, cinnamon, allspice, and nutmeg in a large bowl. In a separate bowl, whisk almond milk and egg together and pour on top of dry ingredients. Add melted coconut oil, agave nectar, and vanilla and whisk all ingredients together. Mix in dates by hand.
Spread mixture into the shape of a circle on a baking sheet. Pat into place until the dough is about a half-inch thick.
Bake uncovered for about 13-15 minutes, rotating the baking sheet about halfway through. Then cover loosely with foil and bake another 2-5 minutes. Remove from oven and let cool for about 10 minutes. Then use a pizza cutter to slice 8 wedges. Leave on baking sheet for about another 10 minutes to allow them to cool even more (heat will escape once the wedges are cut).
