A rich, fudgy brownie with a crackly top, inspired by Betty Crocker’s box mix brownies.

Ingredients

Batter
  • 2 Tbsp (28g) unsalted butter, melted
  • 2 tsp (10mL) canola or other neutral oil
  • 3 "heaping" Tbsp (45g) granulated sugar
  • 1 "heaping" Tbsp (15g) brown sugar
  • 1 egg yolk
  • ¼ tsp vanilla extract
  • 2 "heaping" Tbsp (16g) unsweetened cocoa powder
  • 2 "heaping" Tbsp (20 g) all purpose flour
  • ⅛ tsp salt

Instructions

Directions
  1. Preheat the oven to 350°F. Grease a 10 ounce ramekin.
  2. In a medium bowl, whisk together the melted butter, granulated sugar, and brown sugar for 1–2 minutes. Let the mixture stand for a few moments. You should notice some separation between the butter and sugar.
  3. Add the egg yolk and vanilla. Whisk vigorously for 2 minutes, until the mixture is fluffy and glossy.
  4. Sift in the cocoa powder, flour, and salt. Gently fold until just combined, being careful not to overmix.
  5. Transfer the batter to the prepared ramekin and bake for 18–20 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.

Notes

For the most accurate results, I recommend using the weight measurements provided. Even measuring spoons can vary slightly between sets, which can lead to inconsistent results, especially in a small batch recipe like this one!

Frequently Asked Questions

Can I make this brownie in an 8 ounce ramekin?
Yes! An 8 ounce ramekin will work, but the batter will be a little deeper. Keep the oven temperature at 350°F and expect the brownie to need a few extra minutes. Start checking around 20 minutes, and bake until the top is set and a toothpick inserted into the center comes out with a few moist crumbs.

Why does this brownie have a crackly top?
The crackly crust comes from thoroughly whisking the sugar, butter, and egg yolk before adding the dry ingredients. This helps create the thin, shiny crust that's characteristic of classic brownies.

How do I know when the brownie is done?
The top should look set and slightly crackly, while a toothpick inserted into the center should come out with a few moist crumbs attached. If it comes out completely clean, you've probably gone a little too far.

Can I use melted coconut oil instead of canola oil?
Yes. Melted coconut oil can be substituted for the neutral oil, although it may add a subtle coconut flavor depending on the type you use.

Can I make this brownie without an egg?
I haven't tested this recipe with an egg substitute, so I don't recommend making substitutions if you're specifically after the crackly top and fudgy texture.

Can I make this brownie ahead of time?
Yes. Let it cool completely, then store it covered at room temperature for up to 2 days. For the cleanest slice, chill the brownie before cutting.
