Preheat oven to 350F and prepare an 8" baking pan with parchment paper, set aside.
In a mixing bowl, combine the peanut butter, pumpkin puree and vanilla.
In a separate mixing bowl, stir together the baking soda, flour, sugar and chocolate chips.
Pour the dry ingredients into the wet and keep stirring. If needed, slowly add in the almond milk until the texture is gooey like cookie dough.
Transfer the batter into the prepared pan and smooth down evenly.
Bake 10 minutes. The top will look set, but they will still be undercooked underneath. Leave to cool for at least 20 minutes before trying to slice into bars.
