Let's Make Those Lovely Red Velvet Brownies!
Get your oven ready by preheating it to 350°F (180°C). Line an 8-inch square baking pan with parchment paper, letting a little hang over the sides for easy lifting later.
Melt the butter gently in the microwave in short bursts until it's completely liquid.
In a big mixing bowl, combine the melted butter with both the granulated and light brown sugars. Whisk them together until they're nicely blended.
Add the eggs, extra egg yolk, and vanilla extract. Whisk just until everything is combined, but don't overdo it – we want fudgy, not cakey!
Stir in the vegetable oil and cocoa powder until the batter is smooth.
Here’s the color magic! Scoop out about two tablespoons of your batter into a small separate bowl. Mix in the red gel food coloring until it's completely smooth and lump-free. Then, add this vibrant red mixture back to your main bowl and mix until the whole batter is beautifully colored (it will look dark, but trust the process – it brightens when baked!).
Swap your whisk for a rubber spatula. Gently fold in the all-purpose flour, cornstarch, and salt until there are no dry streaks left.
Stir in the vinegar completely. If you're using white chocolate chips, now’s the time to fold them in.
Pour your gorgeous red batter into the prepared pan. Bake for 20-25 minutes. To check if they're done, insert a toothpick into the center – it should come out with moist crumbs, not wet batter. Be careful not to overbake, or you'll lose that perfect fudgy texture!
Let the brownies cool in the pan for about an hour, then use the parchment paper to lift them out onto a wire rack. They need to cool completely before frosting! This step is super important for clean frosting and slicing.
Whip Up the Dreamy Cream Cheese Frosting!
Make sure your cream cheese and butter are at room temperature – this helps them blend beautifully. In a mixing bowl, beat them together until they're wonderfully smooth and creamy.
Gradually add the powdered sugar, starting on a low speed to avoid a sugar cloud! Once the sugar is incorporated, turn the mixer to high speed and beat for a few minutes until the frosting is light, fluffy, and absolutely irresistible.
Stir in the vanilla extract for that extra touch of deliciousness.
Once your brownies are completely cool, generously spread this luscious cream cheese frosting evenly over the top.
Slice into 16 individual pieces. Now, serve up these delightful Sweetheart Red Velvet Brownies and enjoy every bite!
