Preheat your oven to 350°F (175°C). Grease a 9x5-inch loaf pan or line it with parchment paper.
Whisk almond flour, baking powder, salt, and sweetener together in a large bowl.
In another bowl, beat the eggs, then add almond milk, melted coconut oil (or butter), and vanilla extract.
Combine the wet and dry ingredients until you get a smooth batter.
Fold in the blueberries gently with a spatula, ensuring they are evenly distributed.
Pour the batter into the prepared loaf pan and smooth the top.
Bake for 45 minutes, or until a toothpick inserted in the center comes out clean.
Cool in the pan for 10 minutes, then transfer to a cooling rack.
Slice and enjoy warm or at room temperature!
