Ingredients

Scale

Red Velvet Brownies

  • 6 Tablespoons salted butter
  • 200 grams granulated sugar (1 cup)
  • 55 grams light brown sugar (packed 1/4 cup)
  • 3 large eggs
  • 1 large egg yolk
  • 1 teaspoon vanilla extract or paste
  • 80 ml vegetable oil (1/3 cup)
  • 25 grams cocoa powder (3 ½ Tablespoons)
  • 1/2 teaspoon red gel food coloring
  • 90 grams all-purpose flour (3/4 cup)
  • 1 Tablespoon cornstarch
  • 1/8 teaspoon salt
  • 1 Tablespoon white vinegar

White Chocolate Buttercream Frosting

  • 1/2 cup salted butter (softened)
  • 3 ½ cups powdered sugar
  • 1 teaspoon pure vanilla extract or paste
  • 4 ounces good quality white chocolate (melted, not chocolate chips)
  • 2 Tablespoons heavy whipping cream


Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line an 8-inch square baking pan with parchment paper, ensuring there is an extra 2-inch overhang on the sides for easy removal.
  2. Melt Butter: Melt 6 tablespoons of salted butter in a microwave-safe bowl, stirring every 20 seconds until fully melted.
  3. Mix Sugars and Butter: In a large mixing bowl, whisk together the granulated sugar and light brown sugar, then pour in the melted butter and combine well.
  4. Add Eggs and Vanilla: Mix in the 3 large eggs, 1 egg yolk, and 1 teaspoon vanilla extract or paste until just combined, avoiding over-mixing to prevent air incorporation.
  5. Incorporate Oil and Cocoa: Add the vegetable oil and cocoa powder to the batter and whisk until blended smoothly.
  6. Color the Batter: Remove 2 tablespoons of batter to a small bowl, mix in the red gel food coloring thoroughly, then whisk this vibrant red mixture back into the main batter just until combined.
  7. Fold Dry Ingredients: Switch to a spatula and gently fold in the all-purpose flour, cornstarch, and salt until no lumps remain.
  8. Add Vinegar: Fold in the white vinegar carefully to complete the batter mixing.
  9. Bake the Brownies: Pour the batter evenly into the prepared baking pan and bake for 20 to 25 minutes. Insert a toothpick into the center; it should come out with a few moist crumbs attached.
  10. Cool Completely: Remove the brownies from the oven and allow them to cool fully in the pan before frosting to ensure the frosting sets properly.
  11. Prepare Buttercream: Using a stand mixer, cream the softened 1/2 cup salted butter until light and fluffy. Beat in the vanilla extract.
  12. Add Powdered Sugar: On low speed, gradually add the powdered sugar in half-cup increments, mixing well after each addition until fully incorporated.
  13. Incorporate White Chocolate: Pour in the melted white chocolate and beat on medium speed until completely combined into the frosting.
  14. Finish Frosting: Add the heavy whipping cream and beat until the frosting reaches your preferred spreadable consistency.
  15. Frost the Brownies: Spread the white chocolate buttercream evenly over the cooled brownies. For clean slices, use a plastic knife to cut portions.

Notes

  • Be careful not to over-mix the batter to keep the texture tender and dense.
  • Using good quality white chocolate for the frosting enhances the flavor and smoothness.
  • Allow brownies to cool completely before frosting to prevent melting and sliding of the buttercream.
  • If you prefer deeper red color, increase red gel food coloring slightly but do so gradually.
  • Storing leftovers in an airtight container at room temperature is best for up to 3 days, or refrigerate for up to a week.
