These brownies pass the Passover test and beyond. Decadent, fudgy, and delicious, you’ll want to make these brownies year-round.

Make sure to let the brownies cool completely before cutting so they hold together like a dream.
A Quick DIY for Matzo Cake Meal
While matzo meal and matzo cake meal are essentially the same thing, the coarseness of the grind is different, making each one suitable for different recipes. Matzo cake meal is more fine and powdery, and the better choice for baked goods, like brownies. If you don’t already have a box on hand or can’t find it, it’s quick and easy to make your own at home. Simply process regular matzo meal in a blender or food processor until it’s fine and powdery, about one minute.
Prep time 10 minutes
Cook time 35 minutes to 40 minutes
- 8 tablespoons
(1 stick) butter or vegan buttery stick, plus more for greasing the pan
- 12 ounces
semi-sweet or bittersweet chocolate chips (about 2 cups)
- 2 teaspoons
hot tap water
- 1 teaspoon
instant coffee granules
- 3/4 cup
- 1 teaspoon
- 1/2 cup
matzo cake meal (see Recipe Note)
- 1 tablespoon
- 1/4 teaspoon
fine sea salt
- 1 cup
- 1/2 cup
chopped toasted walnuts or pecans (optional)
Arrange a rack in the middle of the oven and heat the oven to 350ºF. Coat an 8x8-inch square baking pan with butter.
Place 1 stick butter and 12 ounces chocolate chips in a microwave-safe bowl. Microwave on high until melted and smooth when stirred, 60 to 90 seconds. Set aside to cool slightly.
Place 2 teaspoons hot water and 1 teaspoon instant coffee granules in a medium bowl and whisk until the coffee is dissolved. Add 2 large eggs, 3/4 cup granulated sugar, and 1 teaspoon vanilla extract, and whisk to combine.
Place 1/2 cup matzo cake meal, 1 tablespoon potato starch, and 1/4 teaspoon fine salt in a large bowl and whisk to combine. Add the egg mixture and whisk until combined. Add the melted chocolate mixture and fold until combined. Add 1 cup mini marshmallows and 1/2 cup chopped nuts if desired and fold until just combined.
Pour the batter into the prepared pan and smooth the top. Bake until the top is slightly cracked and shiny but the center is still slightly soft, 35 to 40 minutes. Let cool completely on a wire rack (this is important, as the brownies are crumbly when warm/hot but hold together perfectly when cooled) before cutting into 16 squares.
Storage: The brownies can be well wrapped and stored at room temperature for up to 4 days.
Making homemade matzo cake meal: If you can’t find matzo cake meal, process 1/2 cup matzo meal in a blender or food processor until fine and powdery, about 1 minute.
