These Cookies and Cream Cupcakes are soft, fluffy, and packed with Oreos. The cupcakes are made with a white chocolate chips for a rich base and loaded with chopped Oreos then topped with a creamy Oreo ermine frosting that’s smooth, light, and not overly sweet.
Preheat the oven to 350 degrees F. Line 2 cupcake pans with paper liners.
In a large bowl, add the 1 cup unsalted butter and 1 cup granulated sugar. Beat on medium speed with a hand mixer until light and fluffy.
Add in the 2 teaspoons vanilla extract and the 3 large eggs, one at a time, and beat just until the egg is incorporated. Scrape down the sides of the bowl before adding another egg.
In a saucepan, heat 2 cups half and half on medium heat until small bubbles form around the edge of the pan. Don’t let the half-and-half come up to a boil, but steaming is good.
In a heat-proof medium bowl, add 12 ounces white chocolate chips.
Pour the steaming half-and-half into the bowl of white chocolate chips. Let it sit for 5 minutes to let it melt.
Whisk the milk and white chocolate chips until they are completely combined. No bits of chocolate chips will be left.
In a separate medium bowl, add the 3 cups all-purpose flour, 1 teaspoon baking soda, 2 teaspoons baking powder, and 1 teaspoon salt. Whisk to combine.
Begin alternately adding the flour mixture and the half-and-half mixture to the butter/sugar mixture. Add three parts of flour and two parts of liquid starting and ending with the flour mixture.
Once all of the dry ingredients and wet ingredients are incorporated into the butter/sugar mixture, fold in the chopped 20 Oreo cookies (filling removed and reserved). Don’t overmix, the Oreos will make the batter gray. Remember to remove the Oreo filling and set aside for the frosting.
Fill the cupcake liners about ¾ full with cake batter.
Place in the preheated oven and bake for 19 to 22 minutes or until a toothpick inserted into the middle of the cupcakes comes out clean.
Turn out onto a cooling rack to cool completely.
Oreo Frosting
In a medium saucepan, add the 2 cups granulated sugar, ¾ cup all-purpose flour, and ½ teaspoon salt. Whisk to combined.
Slowly pour in the 2 cups whole milk while whisking constantly until all the milk is incorporated.
Place over medium heat while whisking constantly until the mixture thickens. Once you set the medium heat, don’t touch it. The mixture will be thick enough to leave whisk marks and will have a pudding consistency.
Whisk in the 2 teaspoon vanilla extract until combined.
Place the mixture in a heat-proof bowl and place a piece of plastic wrap on top of it. Make sure the plastic wrap is touching the flour/sugar mixture. Let it cool to room temperature or place it in the fridge to speed up the process. You don’t want any heat remaining otherwise it will melt your butter.
Once the mixture has cooled to room temperature, grab a large mixing bowl. Add 2 cups unsalted butter and the reserved Oreo filling to the bowl and beat in a hand mixer on medium speed until light and fluffy.
Add the sugar/flour mixture to the butter 1 to 2 heaping tablespoons at a time until fully combined before adding the next.
Once all of the flour/sugar mixture is combined, fold in the finely crushed 15 Oreos with filling just until combined.
Add the frosting into a piping bag fitted with a large round tip. If you use a star tip, you may have some issues with the bits of Oreo sticking in the tip as you pipe.
Pipe tall swirls on top of the cooled cupcakes.
