Tips for a Perfectly Moist and Chewy Cookie Pie
While we adore cookie pies, we sometimes find that they can lean towards the dry side. The key to a super, moist, and tender cookie pie lies in a reliable base recipe and careful baking. Our recipe provides that perfect foundation. Once you have a great basic cookie dough, you can easily modify it with your favorite mix-ins and toppings. The most crucial tip for avoiding a dry cookie pie is simple: do not overbake it!
Baking for just the right amount of time ensures the center remains wonderfully soft and slightly gooey, while the edges develop a delightful chewiness. Keep a close eye on your oven; ovens vary, so your cookie pie might be ready a minute or two before or after the recommended time. You’re looking for a golden-brown edge and a center that looks set but still slightly soft. Another secret for achieving that coveted moist texture is using a combination of light brown sugar and granulated sugar, along with an extra egg yolk, which adds richness and keeps the crumb tender.
Pssst… if you’re mindful of ‘extra’ calories, you don’t even have to add the frosting. The cookie pie is incredibly delicious on its own! However, we wholeheartedly recommend the frosting. It not only adds a wonderful layer of creamy sweetness but also gives the cookie pie that spectacular, celebratory party effect. And those **sprinkles**! They are truly the crown jewel, transforming your cookie pie into an instant party starter. With this Birthday Party Cookie Pie having entered the building, now you can get your own celebration started and enjoy the goods!

How to Make Your Birthday Party Cookie Pie: Step-by-Step Guide
Follow these detailed instructions to create a show-stopping Birthday Party Cookie Pie that will impress every guest and satisfy every sweet craving. The process is straightforward, ensuring a fun and rewarding baking experience.
Making the Birthday Cookie Pie Base
- Preheat your oven to 350 degrees Fahrenheit (175°C). Prepare a 9-inch pie dish or round baking pan by lightly spraying it with non-stick cooking spray. Set aside.
- In a medium-sized mixing bowl, sift together the all-purpose flour, baking soda, cornstarch, and salt. Sifting helps to aerate the dry ingredients and prevent lumps. Set this mixture aside.
- In a separate large bowl, using an electric mixer on medium speed, beat together the light brown sugar, granulated sugar, and cooled melted butter until the mixture is light, fluffy, and well combined. This usually takes about 2-3 minutes.
- Add in the large egg, extra egg yolk, and vanilla extract to the sugar and butter mixture. Continue to beat until all the ingredients are thoroughly incorporated, scraping down the sides of the bowl as needed.
- Gradually add the dry ingredients (flour mixture) into the wet butter and sugar mixture. Mix on low speed until just combined. Be careful not to overmix, as this can lead to a tough cookie.
- Using a large wooden spoon or a sturdy spatula, gently fold in the Ghirardelli chocolate chips and Reese’s Peanut Butter Chips until they are evenly distributed throughout the dough.
- Transfer the cookie dough batter into your prepared pie dish. Use the back of the spoon or your hands to gently smooth out the top evenly.
- Arrange the 8-12 Mini Reese’s White Chocolate Peanut Butter Cups around the edge of the cookie pie. Space them about an inch in from the rim of the dish and lightly press them into the dough, ensuring their tops are still slightly exposed for a beautiful finish. If you wish to add more cups, simply place them within the inner circle of the initial arrangement.
- Bake the cookie pie for 25 minutes. The edges should be golden brown, and the center should appear set but still slightly soft. Remember, slight underbaking is key for a super moist cookie pie!
- Once baked, remove the pie from the oven and allow it to cool completely in the dish on a wire rack before attempting to frost it. This step is crucial for the frosting to set properly. If you choose not to frost the pie, you can add your sprinkles to the top while it’s still warm, if desired, for them to slightly adhere. If you only want a frosting border instead of covering the entire pie, simply halve the frosting measurements.
Preparing the Vanilla Buttercream Frosting
- Using an electric mixer, beat 1 cup of softened unsalted butter in a large bowl until creamy and smooth.
- Gradually add 3 ½ to 4 cups of confectioners’ sugar, 2 pinches of salt, and 1 tablespoon of vanilla extract. Start mixing on low speed, then increase to medium-high once the sugar is incorporated.
- Add milk, 1 tablespoon at a time (totaling 1-3 tablespoons), beating until you achieve your desired light, fluffy, and spreadable consistency.
- Optional: For an extra festive touch, gently fold in about ½ cup of assorted sprinkles into the buttercream.
Frosting and Decorating the Birthday Cookie Pie
- Once the cookie pie is completely cool, spread or pipe the vanilla buttercream frosting onto the center.
- Using a piping bag fitted with your favorite tip (or a zip-lock bag with a corner snipped off), pipe a decorative border around the edge of the cookie pie. For a simple border, you can pipe small, round balls twice around the edge.
- Generously sprinkle assorted confetti sprinkles over the frosted areas and decorate as desired to make it truly sparkle.
- Slice and serve your magnificent Birthday Party Cookie Pie to eager guests!

Instructions
Birthday Cookie Pie
- Preheat the oven to 350 degrees and spray a 9 inch pie dish or pan with non-stick cooking spray and set aside.
- In a medium bowl, sift together the flour, baking soda, cornstarch, and salt and set aside.
- Using a mixer, beat together the sugars and melted butter on medium speed until well combined.
- Add in the egg, egg yolk, and vanilla extract until well combined.
- Gradually add in dry ingredients into the butter/sugar mixture until well combined.
- Using a large wooden spoon, fold in the all the chocolate chips until just combined.
- Transfer the batter out into the prepared pie dish and smooth out the top.
- Evenly space out the 8 Mini Reese’s Peanut Butter Cups around the cookie pie edge about an inch in from the edge and lightly push them in, with tops still exposed. If you are adding more cups, just add them within the circle of cups.
- Bake for 25 minutes.
- Allow the cookie pie to cool completely before frosting. (If you are not frosting, just add your sprinkles to the top as desired. If you want to just do a frosting border instead of doing the frosting the whole pie, just halve the frosting measurements.)
Vanilla Butter Cream Frosting
- Using a mixer, beat 1 cup softened butter, 3 1/2 to 4 cups confectioners sugar, 2 pinches of salt, 1 tablespoon vanilla, 1-3 tablespoons milk until desired consistency.
- Optional: Add in about 1/2 cup sprinkles and fold in.
- Frost center of cookie and pipe border on top of cookie pie and add sprinkles and decorate as desired.
- Serve!
Notes
- We love using Ghirardelli 60% Cacao Bittersweet Chocolate Baking Chips. They are Ghirardelli’s darkest chocolate chips, delivering intensely rich chocolate flavor, and are a little larger than regular chocolate chips. So good!
- For the border, simply snip a small hole in a large zip-lock bag and pipe some round balls around the cookie twice for an easy decorative touch.
