This July 4th Cookie Cake is soft, chewy and sweet and will be a festive and fun treat to have at your July 4th picnic. Plus, it’s easy to make!
Cookie Cake Ingredients
- 1/2 cup unsalted butter
- 1 cup granulated sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 1 3/4 cups all-purpose flour
- 1/2 teaspoon baking soda
- 1/2 teaspoon cornstarch
- 1/4 teaspoon salt
- 1 cup white chocolate chips
- 1/4 cup sprinkles
Cookie Cake Tips
- Set aside a few sprinkles and white chocolate chips to press on top of the cookie dough before baking for a decorative look.
- Make sure you let the cookie cake cool in the pan for at least 2 to 3 hours to set.
- The cookie cake should be completely cooled before adding the frosting.
Vanilla Buttercream Ingredients
- 1/4 cup unsalted butter
- 1/4 cup vegetable shortening
- 2 cups powdered sugar
- 1/2 teaspoon vanilla extract
- 1 1/2 tablespoon water
- Royal blue gel food coloring
Bakers Tip: Add more water as needed to achieve a pipe-able buttercream.
How To Color Buttercream
- Use a toothpick to add small amounts of food coloring gel at a time.
- Press the toothpick with the coloring gel into the frosting and stir.
- If you need to add more coloring gel use a clean toothpick each time so you won’t get any buttercream into your coloring gel.
I used a Wilton 1M piping tip to pipe the buttercream for this recipe. It’s great for the classic swirl piping and pretty easy to use too. Perfect for decorating this big sugar cookie cake with white chocolate chips and July 4th inspired sprinkles!
Is Refrigerating The Cookie Dough Necessary?
No, not this time but for the sake of time and planning you can refrigerate the dough for 2 to 3 days if needed. Once you’re ready to bake, just break up the pieces of dough and press into the baking pan.
Plan It Out
Luckily, this July 4th cookie cake can be made all in one day. Some things to remember though:
- Let your cookie cake cool completely in its pan before removing. If it’s not completely cooled it could collapse.
- Make sure your cookie cake is completely cooled before applying the buttercream.
