Preheat oven to 350 degrees. Prepare an 8x8 baking pan by lightly greasing it with coconut oil.
Prepare flax egg by combining 2 tablespoons of flaxseed meal with 5 TBSP warm water. Leave to sit for 5 minutes until it thickens.
In a medium bowl, cream together almond butter, melted and cooled coconut oil, coconut sugar, and vanilla extract.
Add almond flour and salt to wet mixture and fold to combine. Add almond milk to help create the blondie batter, and finally add in flax egg.
Transfer batter to your prepared baking pan. Bake for 25-30 minutes until knife inserted comes out clean. It will look slightly underbaked, but that's okay!
Let cool for at least 30 minutes. Slice and enjoy!
