Preheat your oven to 350°F (175°C) and line a muffin tin with paper liners or grease it with cooking spray.
In a large mixing bowl, combine the almond flour, erythritol, baking powder, baking soda, and salt. Stir until well mixed.
In another bowl, whisk together the eggs, almond milk, vanilla extract, and melted coconut oil until smooth.
Pour the wet ingredients into the dry ingredients and mix until just combined. Gently fold in the diced strawberries.
Spoon the batter evenly into the prepared muffin tin, filling each cup about ¾ full.
Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
Allow the muffins to cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.
