Mint oreo brownies

So I found a recipe for this on the internet and couldn't resist. Unfortunately I wasn't feeling rich enough to buy some mint oreos off the internet so i used regular oreos but substituted half the chocolate used for mint aero choc so it still had a hint of mint!
It took soo long to cook..probably near to or just over an hour and they burnt slightly around the edge and were still a bit gooey in the middle - i think it's cause i baked them in quite a deep pan so they were probably thicker than they were meant to be...but they were very tasty and I would recommend them to anyone!

It came from a post for 10 different oreo treats you can make

which is a pretty good little read.

Here is the recipe:

Peppermint Cookies n’ Cream Brownies
1 cup butter
6 oz. unsweetened chocolate, chopped (i used half dairy milk and half mint aero)
3 cups sugar
1/2 tsp salt
2 tsp vanilla extract
4 large eggs, room temperature
1 2/3 cups all purpose flour
1/3 cup unsweetened cocoa powder
3 cups roughly chopped peppermint oreo-type cookies

Preheat oven to 350F. Line a 9×13-inch baking pan with aluminum foil, and grease lightly.
In a medium-large saucepan over low heat, melt together butter and chocolate, stirring occasionally. Whisk in sugar, salt and vanilla, then turn off heat. Whisk in eggs one at a time, waiting until each is fully incorporated before adding the next. Stir in flour and cocoa powder until mixture is uniform. Stir in peppermint oreo cookies and pour batter into prepared pan. Crush 3-4 additional cookies finely and sprinkle on top of batter, if desired.
Bake for about 35 minutes, until a toothpick inserted into the center comes out with moist crumbs, but not coated with batter.
Cool brownies in pan for about 20 minutes, then lift brownies in the foil out of the pan and place on a wire rack to cool completely before slicing.

Makes 36 brownies (or 48 bite-sized brownies).
