Ingredients

Scale
  • 2 ½ cups (312g) all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup (227g) unsalted butter, softened
  • ¾ cup (150g) light brown sugar, packed
  • ½ cup (100g) granulated sugar
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 1 ½ cups (270g) chocolate chips or chunks (semi-sweet or milk chocolate)
  • About 8 ounces (227g) ready-to-roll white fondant
  • Food coloring pens or edible markers
  • Edible gold dust or shimmer powder (optional)
  • Light corn syrup or water (a few drops)

Instructions

  1. Preheat oven to 350°F (175°C). Line a 9-inch round cake pan with parchment paper and lightly grease the sides.
  2. In a medium bowl, whisk together flour, baking soda, and salt. Set aside.
  3. In a mixing bowl, beat softened butter with light brown sugar and granulated sugar until light and fluffy, about 3 minutes.
  4. Beat in eggs one at a time, then stir in vanilla extract until smooth and glossy.
  5. Gradually add the flour mixture, mixing on low speed until just combined. Do not overmix.
  6. Gently fold in chocolate chips using a spatula.
  7. Spread dough evenly into prepared pan, smoothing the top with a spatula or dampened hands.
  8. Bake for 25-30 minutes until edges are golden and center is slightly soft and underbaked.
  9. Cool completely in the pan on a wire rack before removing.
  10. Knead fondant until pliable, roll out to ¼ inch (6mm) thickness on a surface dusted with powdered sugar.
  11. Cut fondant into an 8 x 4 inch (20 x 10 cm) rectangle for the diploma shape.
  12. Decorate fondant with edible markers or food coloring pens; curl edges and secure with a dab of corn syrup or water.
  13. Optionally brush edible gold dust on edges once dry.
  14. Place fondant diploma on cooled cookie cake, off-center or on a corner.
  15. Optionally add piped buttercream accents or sprinkles around edges.

Notes

Do not overmix the dough to avoid toughness. Use softened butter, not melted. Bake until edges are golden but center remains slightly soft for chewy texture. Dust fondant rolling surface with powdered sugar, not flour. Fondant can be decorated with edible markers or food coloring. Store cookie cake wrapped at room temperature for up to 3 days or refrigerated for up to a week. Freeze slices individually for longer storage.
