1-First Step: Preheat your oven to 350°F and grease a 12-inch pizza pan or round cake pan with butter or non-stick spray. Line with parchment if desired for easy removal. Gather all ingredients to streamline this simple sugar cookie cake recipe.

2-Second Step: In a large mixing bowl, cream together 1 cup softened butter, 1 cup granulated sugar, and 1 cup powdered sugar. Beat on medium speed for 2-3 minutes until light and fluffy. This base sets the soft texture for your giant cookie cake.

3-Third Step: Add 2 eggs one at a time, beating well after each. Mix in 1 tsp vanilla extract and 1 tsp baking soda. Scrape down the bowl sides to incorporate everything fully. For vegan adaptations, use flax eggs here.

4-Fourth Step: Gradually stir in 4-5 cups flour, starting with 4 cups. Mix until a soft dough forms that doesn’t stick to hands. If too sticky, add flour 1 tbsp at a time. Knead briefly for even consistency in this easy giant sugar cookie cake.

5-Fifth Step: Press the dough evenly into the prepared pan, aiming for 1/2-inch thickness. Use damp hands or a spatula for smooth edges. For gluten-free, chill dough 10 minutes first to prevent spreading.

6-Sixth Step: Bake at 350°F for 18-22 minutes. Edges turn golden, and center firms up. Rotate pan halfway for even baking. Cool in pan 10 minutes, then transfer to a wire rack. This yields a chewy homemade giant cookie cake.

7-Seventh Step: While cooling, prepare buttercream. Beat 1/2 cup softened butter until creamy. Gradually add 3 cups powdered sugar, 2 tbsp milk, and 1 tsp vanilla. Whip until fluffy. For low-calorie, sub half the butter with yogurt.

8-Final Step: Once fully cooled, spread frosting evenly. Decorate with sprinkles, candies, or piped designs. Chill 30 minutes for set frosting. Slice into 12-16 wedges. Total time: 45 minutes. Serve at parties or enjoy as a delicious sugar cookie cake treat.
