Preheat the oven to 350 degrees and line a loaf pan with parchment paper.
Whisk together the eggs, lemon juice and zest. Stir in the erythritol until dissolved. In a separate bowl, stir together the almond flour, coconut flour, baking soda and salt.
Stir together the wet and dry ingredients until well combined. Fold in the raspberries. Pour the batter into the prepared loaf pan and bake for about 35 minutes or until a toothpick inserted in the center comes out clean.
To make the glaze, stir together coconut milk, lemon juice and zest. Let the bread cool completely, then drizzle glaze over top.
