Oreo Chunk Brownies

This fudgy brownie recipe turns out a nice, sturdy brownie- perfect for swirling in chunks of candy or cookies.


1 pound (4 sticks) unsalted butter
1 pound semi-sweet chocolate (or chocolate chips)
6 ounces unsweetened chocolate, chopped
2 Tablespoons instant espresso powder
7 large eggs
2 Tablespoons vanilla extract
2 1/4 cups granulated white sugar
1 1/4 cups all-purpose flour, divided
1 Tablespoon baking powder
1 teaspoon salt
4 cups (40 cookies) broken Oreos (1 package)


1. Preheat oven to 350°F. Butter and flour 12x18x1-inch pan. Line with foil or parchment that hangs over the sides for ease in getting them out (butter the foil/parchment).

2. In a heatproof, medium-bowl set over a saucepan of simmering water, heat butter, and chocolates until melted and smooth; cool slightly.

3. In a large bowl, whisk together the eggs, espresso powder, vanilla and sugar. Stir the egg mixture into the slightly cooled chocolate mixture. Cool to room temperature.

4. In a medium bowl, sift together 1 cup of flour, baking powder, and salt, then add to batter. In a small bowl, stir Oreos and remaining 1/4 cup flour. Stir cookies into chocolate mixture. Then pour into prepared baking pan and smooth top with a rubber spatula.

5. Bake for 25 to 35 minutes, or until toothpick inserted in center comes out clean with a few crumbs attached; do not overbake! Let cool completely, then cover tightly and chill overnight. Chilled brownies are easier to cut. Dump the chilled brownie pan onto a large cutting board, peel off the foil and cut into squares.


*These taste even better the second day.
*Try adding in different kinds of cookies or candy. I'm thinking Girl Scout Thin Mints next time!

    I am looking for a good dense brownie to make brownies on a stick that look like the retangular popsicles. I would probably omit the cookies. Perhaps, the espresso powder, since they are for kids??
    I’m wanting to make sure I will have no problems keeping then on the stick as I decorate them, is why I’m looking for such a dense brownie. Do you recomend this recipe for what I’m trying to do?? Thank you!

    What exactly does one have to do in the second step? Do you get just double- pan the chocolate and butter? Like with two pans- one filled with water, directly on the stove, and the other set on top of it holding the butter and chocolate

      You need to melt the chocolate without burning it. You can either use a the top of a double boiler, or if you don’t have that, put an inch of water in a large saucepan and bring it to a simmer, then set a heatproof bowl on top of the pan with the chocolate in it and let it melt.

    I would like to make these for an elementary school class for Valentine’s Day. Is the Espresso flavor noticeable, such that kids would not like the taste? Can it be omitted without problem? Thank you.

      It will be fine to leave it out for the kids :)

    These are unbelievably good brownies! I made them without Oreos and in a heart muffin shaped silicone pan for Valentine’s Day. Everyone loved them!
