Preparation
  1. In a large mixing bowl, use a hand mixer to combine the brown sugar, granulated sugar, and softened butter until light and creamy.
  2. Add the egg, egg yolk, and vanilla extract; mix until smooth.
  3. In a separate bowl, whisk together the flour, cocoa powder, baking powder, salt, and baking soda.
  4. Gradually add the dry ingredients to the wet ingredients and mix on low speed until just combined.
  5. Divide dough into three portions, wrap in plastic wrap, and refrigerate for 30 minutes.
Baking

  2. Roll out one dough portion into an 8-inch square, sprinkle with 1/3 of the chocolate chunks, and press in.
  3. Repeat with the second portion on top, adding more chocolate chunks.
  4. Roll the final portion and place on top, pressing in the last chocolate chunks.
  5. Roll the entire stack into a 10-inch square, then cut into 2-inch squares.

  7. Let cool before transferring to a wire rack.

Notes

Serve slightly warm for the best chocolate melting experience. Store in an airtight tin with parchment layers to maintain texture.
