In a large bowl, whisk the Greek yogurt, egg, brown sugar, almond milk, and vanilla until smooth. Whisk in the cooled melted chocolate.

Add the oat flour, cocoa powder, baking powder, and salt. Fold with a spatula just until no dry streaks remain. The batter will be thick.

Fold in most of the remaining chocolate chips, saving a few tablespoons for the top.

Cool completely in the pan before lifting out and slicing into 16 squares. Chill for cleaner cuts if desired.
