Step 1: Preheat the Oven - Start by preheating your oven to 350°F (175°C).
Step 2: Prepare the Batter - In a large mixing bowl, add the melted and cooled coconut oil, sugar-free granulated sweetener, eggs, and vanilla extract. Whisk until well combined and smooth.
Step 3: Combine Dry Ingredients - In another bowl, mix the super fine almond flour, coconut flour, baking powder, and sea salt. Ensure even mixing.
Step 4: Mix Wet and Dry Ingredients - Gradually incorporate the dry mixture into the wet mixture. Stir gently until just combined.
Step 5: Prepare the Topping - In a small bowl, combine chopped pecans, melted coconut oil, sugar-free brown sugar, a pinch of sea salt, and ground cinnamon. Mix well.
Step 6: Assemble the Cake - Pour the batter into a greased 9x9 inch baking pan, spreading it evenly. Sprinkle the pecan topping generously.
Step 7: Bake! - Place the baking pan in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted comes out clean.
Step 8: Cool and Serve - Once baked, cool in the pan for 10 minutes, then transfer to a cooling rack to cool completely before slicing.
