1-First Step: Prep your workspace Preheat your oven to 350°F. Grease a 15×10-inch jelly roll pan or line it with parchment paper for easy release. This setup ensures even baking for your sheet pan cookie cake.

2-Second Step: Cream the wet ingredients In a large bowl, beat 1 cup softened butter with 1 cup brown sugar and 1/2 cup white sugar until light and fluffy, about 2-3 minutes. Add 2 eggs one at a time, then mix in 2 tsp vanilla. For vegan adaptations, use flax eggs here.

3-Third Step: Combine dry ingredients In a separate bowl, whisk 2 1/4 cups flour, 1 tsp baking soda, and 1/2 tsp salt. Gradually add the dry mix to the wet ingredients, stirring until just combined. Avoid overmixing to keep the chewy cookie cake tender. Gluten-free flour works seamlessly in this step.

4-Fourth Step: Fold in chocolate chips Gently fold in 2 cups chocolate chips. For low-calorie versions, choose dark chips. Pro tip: Chill the dough for 30 minutes before spreading for a thicker chocolate chip cookie cake.

5-Fifth Step: Spread and bake Transfer the dough to the prepared pan and spread evenly with a spatula. Bake at 350°F for 20-25 minutes. Edges turn golden, and the center sets but remains soft perfect for easy sheet pan chocolate chip cookies. Test with a toothpick for moist crumbs; adjust time for smaller pans (25-30 minutes for 9×13).

6-Final Step: Finish and serve Frost with cream cheese or chocolate icing if desired, or enjoy plain. Slice into squares. This cookie cake recipe shines at parties, serving 20-30 with budget-friendly appeal under NULL total.
