Blend all wet ingredients together in a blender or food processor until a smoothie-like consistency forms. Set aside.
Add all dry ingredients to a large mixing bowl and mix well. Add the wet to the dry and mix again.
Pour batter into an 8x8 greased pan. Top with chocolate chips for double the chocolate and a pinch of flaky sea salt.
Bake for 30 minutes. Let cool for 10 minutes before cutting and serving. If desired, add a drizzle of cashew vanilla frosting (whisk all frosting ingredients together in a small bowl with a fork until thoroughly combined).
