Preheat oven to 350° and line a 8x8 or 9x9 square pan with parchment paper. Set aside.
In a large bowl, combine almond flour, coconut flour, coconut sugar, chai or pumpkin spice, cinnamon and salt. Mix well. Add in the coconut oil, almond milk, and pumpkin and mix until well combined. Add in the pecans and stir again. Scoop mixture into the prepared pan and spread evenly. Mixture will be thick. Bake 35 minutes. The center will not look done.
While the bars are baking, make the frosting. First make sure the coconut butter (manna) is soft and creamy. Microwave for 30 seconds if needed and stir well to mix.
In a small bowl, combine the coconut butter, maple syrup, coconut oil, vanilla, and salt together. Stir until combined and smooth.
Remove the bars from the oven and let cool. Once cool, spread frosting on top. These are best stored in the fridge to keep fresh.
