If you love Oreos then this is the cake for you… A Cookies and Cream Cake that has crushed Oreos baked into the batter as well as folded into the buttercream.
I took the easy route and opted to use a box cake, a Duncan Hines Classic White Cake Mix to be exact. I made one minor adjustment to the batter, I added in an extra 1/4 cup of water so that the Oreo crumbs wouldn’t thicken the batter too much. Once the batter was ready, I then folded in a cup of Oreo crumbs. To create the crumbs I placed a bunch of Oreos in a Ziploc bag, sealed it and then rolled it with a rolling pin. I left some of the Oreos in fairly large crumbs so that the cake wouldn’t just be speckled with little pieces of Oreos, but have some noticeable pieces. I then divided the batter between two 8-inch round pans that I sprayed with baking spray and baked it in a350 F preheated oven until a cake tester inserted in the middle came out clean, about 25 to 30 minutes. I let the cakes cool for a few minutes and then inverted them on wire racks to cool completely.
Meanwhile, I made the frosting. My go-to frosting is a Fluffy Vanilla Frosting that I got from a Martha Stewart cookbook and have been using for quite some time now when it comes to decorating my cakes. It tastes good (not overly sweet) and holds up well to piping and tinting. If frosting is too soft when you tint it it will only get softer and when you try to pipe it it inevitably droops. While I love using the frosting, I am not a fan of making it. It involves adding the confectioners’ sugar 1/2 cup at a time and raising and lowering the speed of my stand mixer. What ultimately happens, even though I cover the mixer with a kitchen towel, is sugar dust gets everywhere on my counter. I was also concerned that the recipe wouldn’t yield enough frosting to fill, frost & decorate the cake. So, while doing a little research for this cake – I couldn’t decide in the beginning if I should make the cake from scratch or use a box mix – I came across a buttercream frosting that incorporated crushed Oreos that I decided to try. I began by beating the butter in my stand mixer until it was light and fluffy and then added in confectioners’ sugar and heavy cream and mixed it on low speed until the sugar was incorporated and then slowly raised it to medium until everything was well blended. Using a rubber spatula I folded in Oreo cookie crumbs. You may be tempted to make the frosting in advance and then store it in the refrigerator. I suggest not doing that. Doing so will allow the cookie crumbs to soften and when you go to use it your frosting may end up looking more gray than speckled with Oreos.
Once the cake cooled I torte both to remove the small dome that formed during baking and then spread some of the frosting on one the cakes and then topped it with the other. I then crumb coated the cake and refrigerated it for about 15 minutes so the frosting could set and then finished frosting it. I had some remaining Oreo crumbs so I pressed them along the bottom of the cake.
Next, I made the chocolate ganache that I poured on top of the cake and spread around. Using a squeeze bottle I tried to create a chocolate drip around the cake. Unfortunately it was a bit warm in my house so the chocolate didn’t set well (even after refrigerating it for a few minutes) so it was a bit runny, hence the chocolate drizzle running down the sides of the cake. Oh well! Finally, using a Wilton 1M tip I piped dollops with the remaining frosting on top of the cake and place a mini Oreo in each one. A little tip, if you plan on piping frosting that has crumbs in it make sure your tip is large enough for the crumbs to pass through. I actually had a few instances of the crumbs getting stuck.
And there you have it… A Cookies and Cream Cake.
Cookies and Cream Cake
For the Cake:
1 15.25 oz. white cake mix
3 large egg whites
1 1/4 cups water
1/3 cup vegetable oil
1 cup Oreo crumbs
For the Frosting:
3 sticks unsalted butter, at room temperature
5 cups confectioners’ sugar
1 1/3 cups Oreo crumbs
1/4 cup heavy cream
For the Chocolate Ganache:
1 cup (8 ounces) semi-sweet chocolate (can use chocolate chips or a baking bar chopped)
1/2 cup heavy cream
*You will need 1 package of Oreos and 1 small container of mini Oreos
Preheat the oven to 350 F. Spray two 8-inch round cake pans with baking spray or butter and flour.
In a large bowl combine the cake mix, egg whites, water and oil. Prepare according to box directions then fold in the Oreo crumbs. Divide the batter among the two pans and bake in the preheated oven for 25 to 30 minutes, until a cake tested inserted in the middle comes out clean. Let the cakes cool in the pans for 15 minutes and then invert them on a wire rack to cool completely.
While the cakes are cooling make the frosting. Beat the butter on medium speed until light and fluffy. Add in the confectioners’ sugar and heavy cream and beat on low speed until incorporated and then raise the speed to medium and continue beating until well blended. Using a rubber spatula fold in the Oreo crumbs.
Once the cake has cooled, torte, fill and apply a crumb coat. Refrigerate the cake for about 15 minutes.
While the cake is in the refrigerator make the chocolate ganache. Place the chocolate in a bowl. Warm the heavy cream in a small saucepan over low heat until steaming and then pour over the chocolate. Let sit for 5 minutes and then stir until smooth. Set aside until ready to use.
Remove the cake from the refrigerator and finish frosting. If you have Oreo crumbs remaining press them along the bottom of the cake. Once the ganache has thickened, transfer to a squeeze bottle and squeeze some of the ganache on the center of the cake. Using an off-set spatula gently spread the ganache towards the outside of the cake, careful not to let it spill over. Add more ganache is necessary. With the remaining ganache in the squeeze bottle drip the chocolate the chocolate along the sides of the cake. Place in the refrigerator so the chocolate can set.
Once chocolate has set use the remaining frosting to pipe dollops on top of the cake. Add mini Oreos to the dollops or cut larger Oreos in half and add those to the dollops.
