Oreo Brookie Layer Cake

Chocolate cakes are heaven’s desserts and when they are combined with very chocolaty fudge frosting and Oreos, they became most people’s most favourite delight, including mine. This Oreo brookie layer cake is made up with dense and moist chocolate cake, chocolate chip cookie layer, Oreo layer then chocolate fudgy frosting and topped with chocolate chip and Oreo cookies.

This is the most unusual cake combination with all the yummy and delicious layers of cakes and so much chocolate inside. Though baking this cake is little much of time consuming because it is based on different types of layers and all the layers should be baked separately because it’s not a traditional batter cake, you have to make 3 different batters for the cake layers than frosting and ganache and toppings. While eating this monster, one must ignore the calorie intake because this is too heavy but the delicious taste ignores the heaviness.

Oreo Brookie Layer Cake Recipe

Let’s talk about how to build this cookie monster baby cake. The first layer is the cookie layer, which shouldn’t be over baked because it must be slightly golden and lightly baked. The next layer is of brownie that too you have to make yourself. At first you have to make cookie cake, than brownie layer and at last Oreo cake. I love all the layers equally but the fudgy layer is one of my most favourite, because this is made up from melted chocolate that too shouldn’t be over baked because its moistness and density would be affected. When you insert the toothpick in it to check if it is properly cooked or not, make sure the toothpick come out with little crumbs on it, instead of clean.

Chocolate Oreo Layer Cake Recipe

Then the last layer consists of Oreo cake, which is slightly denser then the other layers because the Oreos in the centre of this layer shouldn’t settle at the bottom and for this your cake must be dense enough. After you are done baking all three layers, combine them step by step and then it is all covered with rich buttercream and chocolate frosting and crushed Oreos. For the beautiful appearance and to finish off, drizzle some chocolate ganache and chocolate chip and Oreo cookies at the top and Serve with style.
