1. Creaming the Butter and Sugars: The Secret to a Soft Texture

Start by adding the softened butter, granulated sugar, brown sugar, salt, and vanilla extract to a large mixing bowl. Use an electric hand mixer to cream the ingredients together for 2-3 minutes, or until the mixture becomes creamy and light in color. This step is crucial as it incorporates air into the dough, giving the cookies a soft, chewy texture.

2. Incorporating Eggs and Dry Ingredients: Achieving the Perfect Dough Consistency

Add the eggs and the extra egg yolk to the butter and sugar mixture. Beat them until they are fully combined and the mixture is smooth. Next, gradually add the flour and baking soda, mixing slowly until just combined. Be careful not to overmix, as this can result in tough cookies.

3. Adding Oreo Chunks and Chocolate Chips: How to Ensure Even Distribution

Gently fold in the chocolate chips and Oreo chunks using a spatula. Make sure the chunks and chips are evenly distributed throughout the dough for balanced flavor in every bite. Cover the mixing bowl with plastic wrap and refrigerate the dough for at least an hour, preferably overnight. Chilling the dough enhances the flavors and improves the texture.
