Prep: 17 min | Cook: 30 min | Total: 57 min

Cost: $4.46 total, $0.37 per serving

Ingredients

  • 1/2 cup Unsalted Butter (melted)
  • 2 tbsp Vegetable Oil
  • 1 cup Granulated Sugar
  • 1/3 cup Brown Sugar (packed)
  • 2/3 cup Cocoa Powder (unsweetened)
  • 2 large Eggs
  • 1 tsp Vanilla Extract
  • 1/2 tsp Salt
  • 1/2 cup All-Purpose Flour
  • 1/2 cup Heavy Whipping Cream
  • 1.5 cup Chocolate Chips (semi‑sweet or dark)
  • 2 tbsp Rainbow Sprinkles (for topping)

Instructions

  1. Preheat Oven

    Set the oven to 350°F (175°C) and let it fully preheat.

    Time: PT5M

    Temperature: 350°F

  2. Melt Butter and Combine with Oil

    In a small saucepan or microwave‑safe bowl, melt the unsalted butter until just liquid, then stir in the vegetable oil.

    Time: PT3M

  3. Mix Wet Ingredients

    In a large mixing bowl, combine the melted butter‑oil mixture, granulated sugar, brown sugar, cocoa powder, eggs, vanilla extract, and salt. Whisk until smooth and glossy.

    Time: PT5M

  4. Add Flour

    Sift the all‑purpose flour over the batter and gently fold it in with a spatula until just combined. Do not overmix.

    Time: PT2M

  5. Prepare Baking Pan

    Line the 9x9 inch baking pan with parchment paper (or grease it lightly). This helps with removal later.

    Time: PT2M

  6. Transfer Batter to Pan

    Pour the batter into the prepared pan and smooth the top with the spatula.

    Time: PT2M

  7. Bake Brownies

    Place the pan in the center of the oven and bake for 20‑25 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.

    Time: PT25M

    Temperature: 350°F

  8. Make Chocolate Ganache

    While the brownies bake, heat the heavy whipping cream in a saucepan over medium heat until it just begins to simmer. Remove from heat, add the chocolate chips, and whisk until smooth and glossy.

    Time: PT5M

  9. Cool Brownies Slightly

    When the brownies are done, remove the pan from the oven and let them cool in the pan for about 10 minutes.

    Time: PT10M

  10. Add Ganache and Sprinkles

    Pour the warm chocolate ganache over the top of the brownies, spreading it evenly. Sprinkle rainbow sprinkles over the ganache while it is still soft.

    Time: PT5M

  11. Final Cool and Serve

    Allow the brownies to cool completely (about 30 minutes) before lifting them out using the parchment overhang and cutting into squares.

    Time: PT30M

Critical Success Points

  • • Do not overmix after adding flour.
  • • Check brownies with a toothpick at 20 minutes; they should be moist but not wet.
  • • Ganache must be smooth; whisk vigorously while the chocolate is still warm.
  • • Spread ganache and add sprinkles before the ganache sets.

Safety Warnings

  • • Handle the hot oven and hot ganache with oven mitts to avoid burns.
  • • Do not leave the saucepan unattended while heating cream; it can boil over quickly.
