Preheat your oven to 350ºF (175ºC) and line a muffin tin with 12 muffin cups. This ensures that your muffins won’t stick and will pop out easily once they're baked.
In a large bowl, combine the almond flour, eggs, coconut oil, maple syrup, vanilla, arrowroot starch, baking powder, and sea salt. Stir well, breaking up any clumps until the batter is smooth and creamy.
Once you have a smooth batter, gently stir in the chocolate chips. The chocolate should be evenly distributed throughout the batter.
You can fold the raspberries into the batter, or if you prefer whole pieces, you can add them directly into the muffin cups later.
Using a ¼ cup measuring cup, drop the batter into the muffin liners, filling them about three-quarters full.
If you opted to add the raspberries later, gently push them into the batter in each cup now.
Bake the muffins in your preheated oven for about 20 to 25 minutes, or until the tops are lightly golden and the centers feel firm to a light touch.
Once baked, remove the muffins from the oven and let them cool in the pan for a few minutes before transferring them to a wire rack.
Let the muffins cool completely before serving. These muffins are wonderfully moist, so if you have any leftovers, store them in the fridge.
