Preheat oven to 350°. Spray a 20-well brownie bite pan with baking spray with flour.
In a large bowl, stir together granulated sugar, flour, canola oil, cocoa powder, eggs, salt, and vanilla extract until combined. Add chocolate, stirring to combine. Using a levered 2-tablespoon scoop, divide batter among wells of prepared pan, being careful not to overfill. (There may be batter left over.)
In a medium bowl, stir together pecans and brown sugar. Top brownie batter evenly with pecan mixture.
Bake until a wooden pick inserted in centers comes out with a few moist crumbs, approximately 20 minutes. Let cool in pan for 20 minutes. Remove from pan. Serve warm or at room temperature.
Notes
Brownies can be made up to 3 days in advance and stored in an airtight container at room temperature.
