Preheat the oven to 350°F (175°C). Line a muffin tin with paper liners or grease with cooking spray.
In a large mixing bowl, whisk together the almond flour, gluten-free all purpose flour, baking powder, and salt until well combined.
In a separate mixing bowl, whisk together the eggs, coconut oil, honey, lime zest, and lemon juice until smooth.
Add the wet ingredients to the dry ingredients and stir until just combined.
Spoon the batter into the prepared muffin tin, filling each muffin cup about 2/3 full.
Top each muffin with a sprinkle of sliced almonds.
Bake for 20-25 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
Allow the muffins to cool in the muffin tin for 5 minutes, then transfer to a wire rack to cool completely.
