Blend the eggs for a few minutes until they are frothy and have increased in volume.
Add the wet ingredients - cream cheese, lemon juice, zest and vanilla extract - and blend.
Then add the dry ingredients - almond flour, baking powder, erythritol or your low carb sweetener of choice - and blend until combined. Let the batter sit for a few minutes so the coconut flour can expand.
Fill the batter into 8 paper muffin cups (or use a silicone muffin tray) and add the blackberries. Push some inside the batter and leave some on top. Optional: sprinkle the tops with low carb sweetener.
Bake for 25 minutes or until lightly browned and a toothpick inserted comes out clean.

Notes
Makes 8 muffins. Net carbs per muffin: 3.2g. Weight: about 80g each. This recipe is designed for ground almonds or regular / coarser almond flour. If you want to use super-fine almond flour, you may want to reduce the amount by 1-2 tablespoon as it absorbs more liquid.Don't leave out the lemon zest or lemon juice - it really takes the recipe to the next level. Optional: add a pinch of salt for extra flavor.Let cool fully before removing the paper cases.
