Preparation
- Step 1
Heat the oven to 350 degrees. Grease an 8-by-8-inch metal baking pan with butter and line with one piece of parchment paper, creating overhang on two of the four sides. Grease once more over the pressed-in parchment for additional insurance.
- Step 2
In a medium saucepan, melt the butter and bittersweet chocolate over low heat. Remove from the heat once most of the chocolate has melted, stir in the espresso powder and set aside.
- Step 3
In a large bowl, beat the sugars, eggs, vanilla and salt with a hand mixer on medium speed for about 2 minutes, until much of the sugar has dissolved. Stabilize your bowl with a wet paper towel or a thick kitchen towel underneath, so it doesn’t slide around before proceeding with the next step. Continue beating on low speed and carefully stream in the melted chocolate, aiming toward the edge of the bowl and taking care to not pour the chocolate over the beaters to avoid a mess; beat until no streaks remain.
- Step 4
Add the flour and cocoa powder and mix on low speed until no dry spots remain. Fold in about ¾ of the milk and white chocolates, saving some for the top, then transfer the batter into an even layer in the prepared pan. Sprinkle the remaining milk and white chocolate over the surface.
- Step 5
Bake the batter for about 15 minutes. Once the top starts to look set, remove the pan from the oven and bang it on the counter once or twice — lay a kitchen towel on your counter if you’re worried about damaging it — until cracks start to form on the surface. This ensures a fudgy, but not dense, texture.
- Step 6
Sprinkle with flaky sea salt and return to the oven to finish baking, 10 to 12 minutes, until the edges are set and the center is no longer wobbly when the pan is jiggled. (A toothpick inserted will not come out clean, so trust the process.)
- Step 7
Cool completely to room temperature in the pan, about 2 ½ hours. Slice into 16 pieces to serve. Store leftovers at room temperature in an airtight container for up to 4 days.

I’m 11 years old and just baked this recipe as an activity for a week without school. Unenlightened of the brownie’s incredible taste, I was bewildered by the perfect combination of these three types of chocolate. Surprisingly as well, it was not difficult to bake and didn’t matter that I didn’t add the espresso powder. Melting the chocolate was the hardest part for me, as I took it off the stove too early and left much sticking to the saucepan after I poured it. This recipe’s for sure a keeper.
If there is white chocolate, milk chocolate, baking chocolate and cocoa these are 4 chocolate brownies. Ha, think you can pull the wool over our eyes?
I used entirely white sugar, mixed the eggs after the chocolate, omitted the espresso and cocoa powders, and omitted the mix-in chocolate. Now it’s an easy brownies recipe!
Subbed the extra added chocolate pieces for chopped walnuts in mine and it was soooo good. I will definitely be making again, and will for sure be adding chocolate pieces and walnuts! Also will attempt to sub oil for butter at some point? Some of my family are lactose intolerant and it seems cruel to deprive them. If anyone has attempted this please give me a shout and tell me how it went!
@Abitahooey. Use a good vegan butter. The oil will not give you the best outcome. Some people who ate lactose intolerant can eat butter. Good luck!
I doubled the recipe and baked it in a 9x13" pan; it needed about 15 extra minutes of baking in Step 6, after you bang the pan on the counter. Turned out amazing.
I only had organic cacao, used brown butter, only 72% dark chocolate chips, and used a glass pan 8 x11 so we will see.
