Oh my, these Oreo Brownie Bars are like enjoying Oreos and milk, but even better! Because there's a scratch-made brownie base under those Oreos. And a vanilla icing glaze over them. Which come together to create one indulgently rich and delicious pan of Oreo goodness, for sure.

This recipe calls for making a from-scratch brownie batter to create the bars' base. You could absolutely take a shortcut and use a brownie mix if you'd like, but the from-scratch brownie batter is actually really easy to make. -- And a step whose rich chocolatey result we feel is worth the scratch-made effort.

Oreo Brownie Bars are one indulgently rich and delicious pan of Oreo goodness, for sure!

The only thing that makes the scratch-made brownie batter take longer than a boxed mix to make is melting baker's chocolate and butter together, and then letting the mixture cool to room temperature before mixing up the batter.  Yes, it adds a few minutes, but it's not at all hard.  

So if you've ever been afraid to make from-scratch brownies, we encourage you to take the plunge with this recipe.  The indulgently rich and delicious Oreo Brownie Bars that result are worth it, for sure.

Oreo Brownie Bar Ingredients:

Oreo Brownie Bars are made up of two components -- the Oreo-topped brownie base and a vanilla icing glaze. 

For the brownie base, you'll need:
  • Unsweetened chocolate - A bar of unsweetened baking chocolate brings the scratch-made brownie's chocolate element. Look for baking chocolate near the chocolate chips in the baking aisle of the grocery store.

  • Granulated sugar - A fairly hefty dose of sugar is needed to sweeten the recipe's unsweetened chocolate base.

  • Eggs - Four whole eggs are whipped until fluffy for the brownie batter. With no leavening agent in the batter, eggs take on full responsibility for the brownies' rise.

  • Butter - Serves as the batter's fat and brings richness to the brownie base.

  • Vanilla extract - Rounds out the brownie batter flavor.

  • All-purpose flour - Just one cup of all-purpose flour is used in the brownie batter, and brings structure to the brownies as they bake.

  • Oreos - Crumbled Oreos adorn the entire top of the brownie batter and are the signature element of these tasty bars.

For the icing glaze, you'll need:
  • Powdered sugar - Forms the base of the icing glaze.

  • Butter - Mixes with the powdered sugar to bring a nice richness to the glaze.

  • Vanilla extract - A hearty dose of vanilla extract nicely flavors the glaze. Use pure vanilla extract, rather than imitation, for the best flavor and result.

  • Hot water - A few tablespoons of hot water makes the glaze into a drizzling consistency.

How to Make Oreo Brownie Bars:

Start creating this indulgent Oreo deliciousness by beating some eggs and salt together until they're good and fluffy. 

Since the eggs are fully responsible for the rise of the brownies in this recipe, keep those eggs going for about 3 to 4 minutes until they are frothy and lightening in color. -- This means a good amount of air is incorporated in them, which will help the brownies nicely rise.

Gradually add in the sugar while beating, followed by stirring in the vanilla extract.

Ohhhh, then comes the best part - Pour in a mixture of melted unsweetened chocolate and butter that's been cooled down to almost room temperature, and stir the chocolate in by hand. It wouldn't be brownie bars without the chocolate!

To finish off the brownie batter, fold in a little flour by hand. It's important to do this by hand so as not to completely deflate the beaten eggs. -- They need all that air that was incorporated into them to create the brownie bars' rise.

Once the flour's mixed in, spoon the batter into a baking pan.  Scatter crushed Oreos all over the top and then pop the pan in the oven to bake.

While the brownies are baking, make a really simple vanilla icing glaze with melted butter, powdered sugar, vanilla, and hot water.

Drizzle the glaze all over the brownies just after they come out of the oven, covering the top really good.

Let the Oreo Brownie Bars cool completely, and then you're good to go with digging in to enjoy! And enjoy, we truly think you will.

Now, I've got a little side-note story from way back when I first started making these Oreo Brownie Bars. The first batch I ever made, my husband said "I think I'd like these better without the white stuff on top."  

Well, a comment like that is like double-dog-daring me to do something, so I had to put that concept to the test. I made another batch -- and this time glazed half the pan, and left the other half "without the white stuff," to quote my husband. We then put the two versions through a head-to-head taste test, and -- you guessed it -- the "white stuff" won!  My husband Mark had to eat his words. -- And a lot of Oreo Brownie Bars.
