Preheat your oven to 325 and line a 12 cup muffin pan with parchment liners.
In a large mixing bowl, whisk together the eggs, almond butter, milk, erythritol, vanilla, and lemon juice.
Add in the almond flour, baking soda, and salt and mix well with a spatula or spoon, don’t over-mix.
Fold in 2/3 of the blueberries, then spoon batter into muffin liners to make 12 muffins. Add remaining blueberries to the top of the batter.
Bake in the preheated oven for 18-20 minutes or until tops are browning and a toothpick inserted near the center of one comes out clean. Allow to cool in pan for 5 minutes, then transfer to wire racks to cool completely.
Once cooled, serve or store loosely covered at room temperature for up to two days, or refrigerate or freeze to keep longer.
