1-First Step: Prepare your mise en place Measure all ingredients accurately. Soften butter to room temperature by leaving it out for 1 hour. This ensures even creaming. Sift flour, baking powder, and salt together in a bowl. Spoon flour into the cup rather than scooping to avoid dense dough, a key for sugar cookies that hold shape.

2-Second Step: Cream butter and sugar In a large bowl, beat softened butter and granulated sugar with an electric mixer on medium speed for 3-4 minutes until light and fluffy. Scrape sides often. This incorporates air for soft texture. Add the egg and vanilla extract, beating until fully combined, about 1 minute. For vegan adaptation, mix flax egg first and let sit 5 minutes.

3-Third Step: Combine wet and dry ingredients Gradually add the dry mixture to the wet in three parts, mixing on low speed just until dough forms. Do not overmix, or cookies toughen. Dough should be soft but not sticky. If too sticky for gluten-free flour, add 1 tbsp more flour.

4-Fourth Step: Chill the dough Divide dough in half, flatten into discs, wrap in plastic, and refrigerate 1-2 hours or overnight. Chilling firms the butter, preventing spread, crucial for rolled sugar cookies. Overnight chill deepens flavor.

5-Fifth Step: Preheat and roll dough Preheat oven to 350°F. Line sheets with parchment. On a floured surface, roll one disc to 1/4-inch thick. Use cookie cutters for shapes, dipping in flour to avoid sticking. Place 2 inches apart. Rechill scraps 15 minutes before rerolling. For low-calorie, roll slightly thinner.

6-Sixth Step: Bake to perfection Bake 8-10 minutes until edges are lightly golden. Centers stay pale for softness. Rotate sheets halfway. Cool on sheet 5 minutes, then racks. Avoid overbaking for chewy soft sugar cookies that hold shape.

7-Final Step: Finishing touches and serving Once cool, decorate with icing, sprinkles, or royal icing. Store as below. Pair with milk for classic enjoyment. These steps work for all diets with swaps mentioned.
