Heart Attack Brownies

Heart Attack Brownies

These brownies are crazy insane good. I made them for my birthday instead of cupcakes. Gasp! I brought them into the office and the English natives were blown away. I think for the non foodies in the office the concept of a three layer brownie was something new.

Heart Attack Brownies

The brownies consist of a cookie dough layer, an Oreo layer and a chocolate brownie layer. I wish I’d made two batches. Everyone was ready to break their New Year’s diets.

Heart Attack Brownies


Brownie Layer

10 tbs (140g) unsalted butter

1 1/4 cups sugar

3/4 cup cocoa powder

1/2 tsp salt

2 tsp vanilla

2 eggs

1/2 cup plain flour

Oreo Layer

1 pack (2 English rolls) Oreos

Cookie Dough Layer

1/2 cup unsalted butter (115g)

1/4 cup brown sugar

3/4 cup sugar

1 egg

1 tsp vanilla

1 1/4 cup plain flour

1/2 tsp salt

1/2 tsp baking soda

1/2 tsp baking powder

1 cup chocolate chips


  1. Line a 9 x9 inch pan with parchment paper and preheat the oven to 350 F/180 C. Make the brownie layer. In a saucepan melt the butter of medium heat. Whisk in the sugar and cocoa powder once melted. Add the salt, vanilla, eggs and whisk until combined. Add the flour and mix. Set aside.
  2. Make the cookie dough layer. In a large bowl cream the butter and sugar together on medium speed. Add the eggs and vanilla and mix until combined. Add the flour, salt, baking soda and baking powder and mix until just incorporated. Fold in the chocolate chips by hand.
  3. Start the assembly. Press all of the cookie dough into the bottom of the pan. Layer as many Oreos that will fit on top. Pour the brownie mixture over top evenly.
  4. Bake for 30-35 minutes until a toothpick inserted in the center comes out clean.
