For the Brownie Base
- Ground Flax Seeds – A binding agent providing structure; use chia seeds as a substitute for flax eggs.

Step‑by‑Step Instructions for Vegan Oreo Brownies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures it’s ready for baking your Vegan Oreo Brownies. While your oven is heating, grease a 9×13-inch baking pan with non-stick spray or vegetable oil and line it with parchment paper for easy removal later.
Step 2: Prepare the Flax Eggs
In a small bowl, mix 2 tablespoons of ground flax seeds with 6 tablespoons of water to create your flax eggs. Allow this mixture to sit for about 5-10 minutes until it thickens. This egg substitute will help bind your brownies together while keeping them entirely plant-based.
Step 3: Mix the Dry Ingredients
In a large mixing bowl, combine 1 cup of all-purpose flour, 1 cup of powdered sugar, 1/2 cup of unsweetened cocoa powder, 1 teaspoon of baking powder, and a pinch of salt. Whisk these dry ingredients together until well blended, ensuring there are no clumps of cocoa, which will give your Vegan Oreo Brownies a smooth texture.
Step 4: Combine the Wet Ingredients
In a separate bowl, whisk together 1 cup of unsweetened soy milk, the prepared flax egg mixture, 1/2 cup of vegetable oil, and 1 teaspoon of vanilla extract. Mix thoroughly to incorporate all the ingredients, creating a uniform wet mixture that will add moisture to your brownie batter.
Step 5: Create the Brownie Batter
Pour the wet mixture into the bowl with the dry ingredients. Stir gently until just combined, taking care not to overmix the batter. The goal is a homogeneous consistency with no dry patches visible; your batter should be rich and thick, perfect for these Vegan Oreo Brownies.
Step 6: Transfer to Baking Pan
Pour the brownie batter into the lined baking pan and use a spatula to smooth it out evenly across the surface. This step ensures that your brownies bake uniformly, giving you that fudgy texture everyone loves in a brownie.
Step 7: Add the Oreo Pieces
Once the batter is smoothed out, sprinkle broken pieces of Oreo cookies generously over the top. Lightly press the cookie pieces into the batter so that they integrate while baking, adding that delightful crunch and irresistible flavor characteristic of Vegan Oreo Brownies.
Step 8: Bake the Brownies
Place the pan in the preheated oven and bake for 30-35 minutes. To check for doneness, insert a toothpick into the center; it should come out mostly clean with a few moist crumbs attached. This indicates your brownies are perfectly baked and fudgy.
Step 9: Cool and Serve
After baking, remove the pan from the oven and let the brownies cool in the pan for at least 20 minutes. Once cooled, carefully lift them out using the parchment paper, cut into squares, and prepare to serve. These Vegan Oreo Brownies are now ready to be enjoyed!

Helpful Tricks for Vegan Oreo Brownies
- Mix with Care: Avoid overmixing the batter, as this can lead to tough Vegan Oreo Brownies. Stir just until combined for a tender texture.
- Cooling Time: Patience is key! Allow the brownies to cool for at least 20 minutes before cutting. This prevents crumbling and ensures clean, beautiful slices.
- Fresh Ingredients: Make sure your baking powder is fresh for the best rise. Old leavening agents can result in dense brownies.
- Check Early: To prevent overbaking, check for doneness a few minutes before the timer goes off. The toothpick should come out with moist crumbs—not wet batter!
- Creative Substitutes: Feel free to swap the vegetable oil for melted coconut oil for a hint of tropical flavor or use almond milk instead of soy milk for a subtle change.

Vegan Oreo Brownies Recipe FAQs
What type of Oreos should I use?
Absolutely! While classic Oreos are always a hit, feel free to use any chocolate sandwich cookie that’s vegan-friendly. Look for options like Oreo Thins or other brands that meet your dietary preferences. Just ensure they’re dairy-free for a true vegan experience!
How should I store the Vegan Oreo Brownies?
You can store your Vegan Oreo Brownies in an airtight container at room temperature for up to 3 days. If you want to prolong their life, place them in the fridge for up to 5 days. Just be sure they are sealed well to maintain their delicious fudginess!
Can I freeze the Vegan Oreo Brownies?
Certainly! To freeze, allow the brownies to cool completely, then cut them into squares. Place them in an airtight container or freezer bag and store for up to 2 months. When you’re ready to enjoy, simply thaw in the fridge overnight, or heat in the microwave for about 10-15 seconds for that freshly baked taste!
What should I do if my brownies are too dry?
No problem! If you find that your Vegan Oreo Brownies turn out too dry, it may be due to overbaking or using too much flour. Next time, try checking for doneness a few minutes early, and ensure you’re lightly spooning your flour into the measuring cup instead of packing it. This helps maintain that delightful moistness!
Are children and pets safe around these brownies?
Great question! These Vegan Oreo Brownies are free of common allergens like eggs and dairy, making them suitable for most children. However, always be cautious with pets, especially if they might be tempted by a chocolate brownie. Chocolate should never be fed to dogs or cats due to its toxic effects—so keep a close eye!
What can I use instead of ground flax seeds?
If you don’t have ground flax seeds on hand, you can use chia seeds as a substitute for your flax eggs. Simply follow the same ratio: mix 2 tablespoons of chia seeds with 6 tablespoons of water, and let it thicken for about 5-10 minutes before adding to your mixture. They create a similar binding effect and keep your brownies perfectly vegan!
