These decadent Oreo brownies are easy to make, and embedded with chocolate chips and tons of Oreo cookies, they have a deep chocolate flavor, a shiny crackle top thanks to an easy trick, and are healthier, naturally dairy-free and gluten-free.

If you love Oreos, you'll love these Oreo brownies with a delicious fudge texture, a crunchy cookie layer, and a shiny brownie top. The nutritional value is higher than normal for a brownie, with protein and fiber thanks to oat flour and flax seed eggs.

I love brownies, especially when they include healthier ingredients such as my Cauliflower Brownies and my Pumpkin Brownies. And these are exceptionally healthier thanks to the combination of oat flour and flax seed.

Why You'll Love This Recipe

Healthier brownies : These brownies have 4 grams of protein and 3 grams of fiber. This is largely because of the oat flour and flax seed eggs. Oat flour is high in healthy carbs, those known to lower cholesterol, and also rich in vitamins such as calcium, iron, zinc and magnesium. [source] Meanwhile, flaxseeds are high in omegas and fiber, essential to every cell process in your body

Shiny brownie top : It's easy to achieve, just melt the sugar in hot water in the early steps of the recipe.

Easy to make gluten-free : Oat flour not only brings more fiber to the brownie, it makes it naturally gluten-free as well. You can make your own oat flour by blending rolled oats. Typically one cup of oats yields ½ cup of flour.

Deep chocolate flavor : The deep chocolate flavor comes from many sources including cocoa powder, chocolate chips and the Oreo cookies.

Ingredients You'll Need

oat flour - a super healthy flour that can be bought or made from rolled oats or use all purpose flour, just use less because oat flour is lighter.
flax seed eggs or unsweetened apple sauce - either is a great egg replacer. Flax seeds are high in fiber so great for digestion and studies show they have a positive impact on blood cholesterol.
organic cane sugar - I love Wholesome brand but any cane sugar will work.
cocoa powder - you can use healthier cacao powder but if you want to stick to cocoa powder, be sure to use unsweetened.
olive oil - or use avocado oil. Don't use an unhealthy vegetable oil or you'll lose the heart health aspect.
chocolate chips - only a few are necessary for the top fudge factor
Oreo cookies - Use large or small, or feel free to substitute with another chocolate sandwich cookie.
vanilla & salt

Substitutions

1. Oat flour can be swapped for all purpose flour just be sure to use less all purpose flour - I provide exact measurements for both flours in the recipe.

2. Flax seed eggs or apple sauce are fine for egg replacers.

3. Coconut sugar can be used instead of cane sugar, but you probably won't achieve the shine and the flavor will be more maple.

4. Cocoa powder is best, but cacao powder can also be used.

5. Olive oil or avocado oil can be used

6. Oreo cookies now come in a gluten-free version so by all means, use those if you need the brownies to be gluten-free.

How to Make

Step 1. Preheat oven to 350 F. Line an 8x8-inch baking pan with parchment paper.

Step 2. Stir together 2 tablespoon ground flax seeds and 5 tablespoon of water and set aside for 10 minutes to thicken.

Step 3. Add sugar and ½ cup of water to a sauce pan, simmer on low and stir until all sugar is melted. Do not leave it alone or let it boil, and it's very important to continuously stir. It should take about 2-3 minutes to melt all the sugar and render the water clear yet golden. See the recipe card for helpful images.

Step 4. Throw the rest of the ingredients into the bowl and stir or hand-mix until just combined. Do not over mix or you will incorporate too much air and throw off the texture.

Step 5. Pour mixture into the baking pan, layer with broken Oreos, and bake for roughly 30-35 minute or until the top crackles.

Baking Tips

To melt sugar : Be sure to warm the water on simmer for a few minutes. Then pour in the sugar and stir continuously until all granuales are melted. Be sure to start with a clean pan, with an intact surface. You don't want the stir to fleck specks into your sugar. The melting process should take about 2-3 minutes. The water should be clear and golden.

Oreo cookies : You can use mini Oreos, regular size, and you can use them whole or break them in half. Do not crumble them, and do not remove the white filling. You can also use any other brand of chocolate sandwich cookie.

Baking time : You want the top to crack a bit, but you don't want to burn the edges so watch the baking of these closely. Start watching around 30 minutes through the oven window. You can test successfully with a knife - if the knife comes out clean they are done.

Recipe Information

Get Brownie Crackle Top Without Eggs

It's not easy to get that crackle on top without eggs. I find I can get it somewhat with aquafaba, but the best way to achieve that shiny crackle top is to dissolve the sugar in water.

Olive Oil replaces Butter in Oreo Brownies

Brownies are often made by creaming butter with sugar. Olive oil is arguably healthier than butter, so I used it here and 'creamed' or melted the sugar in water to achieve that crackle top.
