Instructions & Video
Melt the chocolate and butter over low heat.
Mix the batter until smooth.
Transfer to a lined baking dish and bake about 30 minutes.
Cool, slice, and serve.
- Prepare the chocolate mixture: In a small saucepan over low heat, melt the unsalted butter. Add the semi-sweet chocolate chips and stir constantly until the mixture is completely melted and smooth. Remove from heat and let cool slightly.
- Mix the sugars: In a large bowl, combine white sugar and packed brown sugar, whisking until well mixed.
- Incorporate wet ingredients: Add the eggs, vanilla extract, and salt to the sugar mixture. Whisk until smooth and slightly fluffy, then stir in the cooled chocolate-butter mixture.
- Combine dry ingredients: Sift in the all-purpose flour and unsweetened cocoa powder. Fold gently until the batter is even and free of lumps.
- Add Oreos: Fold in roughly crushed Oreo cookies so they are evenly distributed throughout the batter.
- Preheat and prepare: Preheat the oven to 350°F (175°C). Line an 8”x8” (20cm x 20cm) baking dish with parchment paper.
- Pour and top: Pour the batter into the prepared dish and spread it evenly. For extra indulgence, sprinkle additional chocolate chips and crushed Oreos on top.
- Bake: Bake for about 30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs for fudgy brownies, or clean for a cakier texture.
- Cool and serve: Let the brownies cool in the pan for at least 20 minutes before slicing into squares and serving.
Substitutions
- Unsalted butter: Use margarine or coconut oil if preferred.
- Semi-sweet chocolate: Swap for dark chocolate chips or chopped bars for a deeper flavor.
- White sugar / brown sugar: Try coconut sugar or a little honey for a different sweetness profile (adjust liquids as needed).
- Eggs: Replace with a flax egg (1 tbsp ground flax + 3 tbsp water), applesauce, or mashed banana for egg-free options.
- Vanilla extract: Almond or maple extract can add a unique twist.
- All-purpose flour: Substitute a whole-wheat or gluten-free flour blend to meet dietary needs.
- Cocoa powder: Use Dutch-processed cocoa or cacao powder for varied intensity.
- Oreos: Any chocolate sandwich cookie or chopped chocolate bars work in a pinch.
Equipment
- Small saucepan
- 8”x8” deep baking dish
- Large mixing bowl
- Spatula
- Whisk
How to Store and Reheat
- To store: Place leftover brownies in an airtight container and refrigerate. They will keep for several days.
- To reheat: Warm individual pieces briefly in the microwave on medium power, or place in a 350°F oven for a few minutes until just warmed through.
3 Top Tips for Success
- Use quality ingredients: Good chocolate, fresh eggs, and real butter make a noticeable difference in flavor and texture.
- Handle Oreos gently: Crush cookies into varied-sized pieces rather than dusting them completely—this preserves pleasant crunchy pockets in the brownies.
- Watch bake time: Remove the brownies while the center still has a few moist crumbs for a fudgy finish. Overbaking dries them out.
