These Oreo blondies are what happens if you take a fudgy brownie, take out the cocoa powder and add in a bunch of chopped Oreos. They are SO good. These cookies and cream blondies also use brown butter to give them a rich and gourmet flavor.
These Oreo blondies are pure heaven and they are super easy to make. These bars are packed with flavor because of brown butter! Brown butter can take any dessert and give it a richer and more gourmet flavor.
Why You Will Love This
- Super easy to make- These bars are ready to make into the oven after 30 minutes! The longest part is letting the brown butter cool slightly.
- No mixer required- All you need is a whisk and mixing bowls!
- Brown butter- The brown butter makes these blondies taste so rich.
- Oreo- There is so many Oreos in this recipe. The more the merrier!
- Mini chocolate chips- The chocolate chips give these bars pockets of chocolate.
Here are some notes about the ingredients used.
- Brown butter- After the butter is browned, it looses 20% of the water content. Which is why there are more eggs to make up for it.
- Brown sugar- You can use dark or light for this recipe. I used light.
- Cold eggs- These eggs are used cold because it gives it a fudgier texture.
- Egg yolk- The 2 egg yolk is to add more moisture and richness to these bars.
- No rising agent- There is no rising agent because since we are going for fudgy, if there was baking soda/powder it would cause it to rise while baking, and sink while cooling.
- Oreos- You can use any type of Oreo you would like.
- Mini chocolate chips- You can use regular chocolate chips, but I prefer mini pockets of chocolate.
Step By Step Instructions
Here are all the steps to make these Oreo blondies from start to finish.
STEP 1: Start by browning the butter in a large frying pan. Let the butter melt completely. Stir constantly. Once the foam builds up in the butter and it is hard to see the bottom, then the butter is almost done browning.
STEP 2: Once the butter milk deposits and the butter turns a light amber, take off the heat. Next, let the butter cool for 15 minutes. Hot butter can cook the eggs, which we don't want.
STEP 3: Mix the dry ingredients together. Next, whisk the browned butter and both sugar together. Then, add in vanilla, eggs, and egg yolks. It should be light and creamy.
STEP 4: Add in the dry ingredients. Once mixed, add in the Oreos and mini chocolate chips. Once all combined, pour into an 8X8 pan. Top with extra chocolate chips and Oreo pieces.
STEP 5: Bake for 30-40 minutes. Place the pan on a cooling rack, then let it cool completely before cutting and serving.
When you are making the brown butter, it will go by faster and easier if you use a large frying pan. A large pan can brown the butter with more surface area.
Melt the brown butter first. Then, it start to bubble. Once it starts to foam up, watch it carefully. It can go from regular, to browned, to burnt very easily.
Once the butter is foaming a lot and you can't see the bottom, whisk quickly. Once the milk deposits separate it will turn amber quickly.
- Regular butter- You can use regular butter instead of browned. Use 2 regular eggs and 1 egg yolk if using regular butter.
- Oreos- You can use any flavor Oreo or even any cookie. Nutter butters or animal crackers would taste great with it!
- Mini chocolate chips- You can use any type of chocolate chip. I strongly recommend not using milk chocolate. That would be too sweet.
No, please use the 2 eggs and 2 egg yolks. The reason is because with the reduced water from the browned butter, it needs the extra fat from the yolk. Also, egg yolks help make for a fudgier blondie.
I haven't recipe tested this. I don't suggest making this with no eggs.
I have not recipe test this. However Bob's Red Mill 1:1 gluten free flour should work.
