Preheat the oven to 350°F. Lightly grease a large baking dish with coconut oil. Set aside.
In a large bowl, place the rhubarb, strawberries, raspberries, maple syrup, and vanilla. Mix well until combined. Set aside.
In another large bowl, mix the flour, brown sugar, baking powder, baking soda, and salt. Whisk until fully combined.
Add the coconut oil and use your hands to rub it into the flour mixture, until the largest pieces of oil are no bigger than a pea.
Add the almond milk and stir until just combined. Be careful not to over-mix.
Using your hands or a back of a spoon, cover the bottom and sides of the greased baking dish with the scone dough.
Pour the fruit mixture over the dough while spreading evenly with the back of a spoon.
Bake the cobbler for 40-45 minutes, or until the fruit is bubbling and the scones on the sides are golden.
Remove from the oven and cool for 15 minutes before serving.
Serve as is or with vegan ice cream. Enjoy with family and friends!
