These simple yet indulgent Oreo brownies infuse rich, fudgy brownies with crunchy chocolate Oreo cookies for a decadent combination that will easily become a favorite for all ages!
Preheat the oven to 175 C / 350 F (no fan) and prepare a 9-inch / 23 cm brownie tin. Brush the inside of the pan with a tiny bit of oil, and then line the bottom and sides with parchment paper.
Arrange the Oreo cookies on the bottom of the brownie pan. I could fit 16 Oreos into my pan. Set the pan aside.
Gently melt the butter and the chocolate in a bowl over simmering water over low-medium heat. Alternatively, use your microwave; however, ensure that you don't burn the chocolate.
In another bowl, whip together the eggs with sugar with the help of an electric hand mixer or stand mixer until pale, for about 5-7 minutes.
Slowly pour the melted butter and chocolate mixture into the egg-sugar mixture while the mixer is on low speed.
Lastly, sift the dry ingredients (flour, salt, and cocoa powder) into the wet ingredients, and fold the mixture together with a rubber spatula. Do not overmix.
Pour the brownie batter on top of the Oreos. Crush the remaining Oreos (7) into smaller chunks and place them all over the brownie batter.
Bake
Bake the Oreo brownies at 175 C / 350 F for about 35-40 minutes. The brownie is ready when the edge looks baked and the middle looks slightly gooey but not raw. Do not overbake! The brownie will set further as it cools.
Let your brownie completely cool in the pan before slicing and serving.
Any leftovers can be stored in an airtight container for 2-3 days at room temperature.
Notes
INGREDIENT NOTES
Always use unsalted butter to make the brownies, however, add the salt separately. This way, you are in control of the quantity of the salt.
The egg should be used at room temperature for proper emulsification.
The quality of the chocolate and the cocoa powder will define the taste of your brownies, so try to use high-quality ingredients, e.g., semi-sweet chocolate from Lindt or Callebaut and Dutch-processed cocoa powder.
TECHNIQUE NOTES
A digital scale is required for a consistent, happy baking experience.
If your preferred chocolate melting method is a microwave, not the double boiler, use a plastic container to melt it. The glass can very quickly heat up and might burn your chocolate.
Always preheat your oven and consider using a digital oven thermometer for the best results.
Each oven is different, so you might need to adjust the baking time +/- 5- 10 minutes.
For the best fudge brownie experience, consider slightly underbaking your dessert.
You have to wait until the brownie cooled to room temperature; otherwise, it´s impossible to make a nice, clean cut.
