Preheat the oven to 350°F (177°C).
In an 8-inch square baking dish, combine the rhubarb, strawberries, orange juice, 2 tbsp maple syrup, and 2 tbsp coconut flour. Mix until well combined.
In a separate bowl, mix the pecans, almond flour, almond butter, cinnamon, remaining 2 tbsp maple syrup, and remaining 1 tbsp coconut flour until combined.
Crumble the topping evenly over the fruit mixture.
Cover with foil and bake for 30 minutes. Remove the foil and bake for an additional 10 minutes, or until the topping is golden and the fruit is bubbling.
Let cool for about 5 minutes before serving. Enjoy!
