Preheat oven to 350°F (175°C). Line an 8x8-inch pan with parchment.
Soak pitted dates in hot water for 10 minutes if dry; drain well.
In a food processor, blend dates and maple syrup to a thick paste.
Add eggs and vanilla; blend until very smooth.
Add melted (but cooled) butter or coconut oil; blend until creamy.
Add cocoa, almond flour, salt, and baking powder; pulse to combine well.
Stir or pulse in chocolate chips.
Spread batter evenly in prepared pan.
Bake 22–26 minutes, just until the edges are set and the center looks slightly gooey.
Cool completely for the fudgiest texture; refrigerate for extra chew.
