Preheat the oven to 375°F or 190°C. Grease a 9x5 inch loaf pan with coconut oil, vegetable oil, or vegan butter.
In a small bowl with a fork, stir together the almond butter, coconut oil, and almond extract until well combined. Add the sugar, flours, and salt, pushing the fork through the mixture until crumbly and the flour is no longer visible. Some crumbs will be larger and others will be smaller.
Cover the topping mixture and place in the fridge while you make the filling.
In a large bowl, combine all the ingredients for the filling and stir until no flour is present and the pears are well coated. Cover and set aside.
Spread the pear mixture evenly into the greased loaf pan. Crumble the topping over the pears evenly.
Bake for 1 hour, covering the pan with tin foil after 40 minutes to prevent the crumble from being too dark. After taking the pan out of the oven, sprinkle the 1 teaspoon of brown sugar on top (optional). Eat warm and enjoy!
