Preheat oven to 350. Lightly oil an 8x8” baking dish or line it with parchment paper.
In a bowl or mixer, combine the pumpkin puree, eggs, vanilla extract, lemon juice, grated ginger and coconut sugar. In a separate bowl, add the remaining ingredients and sift/whisk to combine. Incorporate the dry ingredients into the pumpkin mixture and mix just until all ingredients are incorporated.
Pour the pumpkin bar batter into the baking dish. Spread all the way to the edges of the baking dish to ensure there is an even layer. Use a knife to spread the batter smooth; since this recipe includes coconut flour only, the batter will stay in the same position throughout baking that you put it in (it will not enlarge or rise).
Bake 20 to 23 minutes until edges are golden brown. Allow to cool 15 minutes before serving.
