Gooey and Decadent: Why Lunch Lady Brownies Are a Must-Make

These Lunch Lady Brownies combine deep cocoa flavor, a tender crumb, and a sweet frosting finish for a classic treat that never goes out of style.

Pro Tips for Perfect Lunch Lady Brownies

  1. Use room-temperature eggs: They blend in smoother and help create that tender texture.
  2. Don’t overmix after adding flour: Overmixing can lead to tougher brownies instead of the desired fudgy chew.
  3. Bake until the surface is matte and bubbly: That signals a perfect doneness — not underbaked and not dry.
  4. Frost while warm: Spread the chocolate frosting immediately after the brownies come out of the oven so it melts in slightly for a soft, glossy finish.
  5. Allow full cooling before slicing: Cooling ensures clean cuts and prevents the frosting from sliding.
  6. Sprinkle generously: Rainbow sprinkles add fun and festive flair — perfect for sharing or special occasions.

Lunch Lady Brownies Recipe

Preparation time: 10 minutes
Cooking time: 20–30 minutes (depending on pan size)
Serves: 12–16 squares
Equipment: 10×15 in jelly-roll pan or 9×13 in baking pan, mixing bowls, hand or stand mixer.

Ingredients:

For the Lunch Lady Brownies

  • 1 cup (220 g) unsalted butter, melted
  • 2 tablespoon vegetable oil
  • ½ cup (50 g) unsweetened cocoa powder
  • ½ teaspoon salt
  • 2 cups (265 g) all-purpose flour
  • 1 cup (200 g) granulated sugar
  • 1 cup (200 g) dark brown sugar, packed
  • 4 large eggs, room temperature
  • 1 tablespoon vanilla extract

For the Chocolate Frosting

  • ¼ cup (55 g) unsalted butter, softened
  • Pinch of salt
  • ¼ cup (25 g) unsweetened cocoa powder
  • 2½ cups (270 g) powdered sugar
  • ¼ cup (55 g) milk
  • 1 teaspoon vanilla extract
  • Rainbow sprinkles

Directions:

  1. Preheat the oven and prepare the pan: Preheat the oven to 350 °F (175 °C) and grease a 10×15 inch jelly-roll pan or a 9×13 inch baking pan.
  2. Mix melted butter, oil and cocoa: In a large bowl, whisk together the melted butter, vegetable oil, and unsweetened cocoa powder until smooth.
  3. Add dry ingredients: Stir in the salt, flour, granulated sugar, and dark brown sugar until the mixture begins to hold together.
  4. Incorporate eggs and vanilla: Whisk in the eggs and vanilla extract until the batter is evenly combined and glossy.
  5. Spread the batter: Pour the batter into the prepared pan and spread it evenly using a spatula or the back of a spoon.
  6. Bake the brownies: For the 10×15 pan, bake for about 15–20 minutes. For a 9×13 pan, bake 25–30 minutes. The brownies are done when the surface is matte and bubbly, and the center is bouncy to the touch.
  7. Prepare the frosting right away: Just as the brownies come out of the oven, begin the frosting. In a bowl using a hand mixer or stand mixer with the paddle attachment, mix together the softened butter, pinch of salt, and cocoa powder. Then add the powdered sugar one cup at a time, followed by the milk and vanilla extract, mixing until smooth.
  8. Frost the warm brownies and add sprinkles: Spread the frosting evenly on the warm brownies, then immediately top with rainbow sprinkles for that vibrant finish.
  9. Cool completely and slice: Allow the brownies to cool completely in the pan before slicing into squares for clean edges and the perfect texture.
