Preheat oven to 350 degrees F. Line an 8x8 square pan with parchment paper.
In a medium bowl, make the flax eggs by combining the ground flaxseed with water. Set aside for 5 minutes to thicken.
In a large bowl, add the oat flour, almond flour, cacao powder, baking soda, and salt. Whisk until well combined.
In the bowl with the flax egg, add the avocado oil, almond milk, vanilla, and sugar. Whisk until well combined.
Add the wet ingredients to the dry. Use a rubber spatula and mix until just combined. Fold in the chocolate chips and raspberries.
Transfer batter to the lined baking pan. Spread batter out evenly. Top with extra chocolate chips and raspberries. Bake for 30 minutes. Let it cool completely before slicing. I like to put it in the fridge for a few hours once cooled to make slicing easier. It is very fudgy. Enjoy! Store leftovers in the fridge.
