Make the Cookie Cake

Step 1: Preheat the oven

Preheat the oven to 350°F.

Step 2: Spray your baking pans with baking spray

Spray a 9-inch cookie (or cake) pan lightly with non-stick baking spray.

Step 3: Line the bottom of the pan with parchment paper

Place a parchment circle in the bottom and spray the top with non-stick spray. If using a cake pan, be sure to spray the sides of the pan, and set it aside.

Step 4: Cream together butter and sugar

In a mixing bowl, cream butter and both sugars for 3-4 mins.

Step 5: Add in eggs and vanilla

Add in the eggs and vanilla. Mix until incorporated.

Step 7: Mix in the remaining dry ingredients

Add in the flour, baking powder, and kosher salt. Mix in fully.

Step 8: Fold in the sprinkles

Add 1 cup of rainbow sprinkles and fold them into the cookie batter.

Step 9: Spread the batter into the bottom of the pan

The batter will be thick, place dough in the center of the pan. Spread out with a spatula (an offset spatula works great).

Step 10: Press the dough into the pan

Press dough in the pan leaving room around the edges so it has space to spread.

Step 11: Bake until slightly golden

Bake in a preheated oven for 18-20 mins until lightly golden.

Step 12: Remove from the oven

Remove from the oven and allow the cookie cake to continue baking in the pan but outside the oven for an additional 10-15 mins.

Step 13: Remove from the pan

Remove from the pan and onto a cake board or turntable or cake stand.

Step 3: Add creamer or milk

💭 Tips

Want to make sure that your cake comes out perfectly? Here are some tips to help you get the best results possible from your cookie cake.

  • Be sure to spray your baking dish well, so that your cookie cake does not stick.
  • Make sure that you use baking spray instead of nonstick cooking spray. This will help prevent your cookie cake from sticking to the pan.
  • Using a parchment round will help the cookie cake come out of the pan cleanly and evenly, however, you can make this without the parchment round if you prefer.
  • Do not mix your cake batter too much or your cookie cake will be tough.
  • Make sure you use room temperature butter and eggs so that they mix evenly into the batter.
  • Add sprinkles slowly, so that they don’t bleed their color into the batter.
  • When measuring your flour, be sure to spoon it into the measuring cup and level it off with the back of a knife.
