1-First Step: Preheat and Prep Preheat your oven to 325°F (165°C) and line an 8-inch square pan with parchment paper. Soften 1 cup (225g) unsalted butter to room temperature; it should yield slightly to pressure. This step, or mise en place, sets you up for smooth mixing in this easy vanilla shortbread cookie recipe. Measure all ingredients ahead to avoid pauses.

2-Second Step: Cream Butter and Sugar In a large bowl, beat softened butter with ½ cup (100g) granulated sugar using a hand mixer on medium speed for 2 minutes. The mixture turns light and fluffy, trapping air for tenderness. Scrape sides often. For vegan adaptations, use plant-based butter here; it creams similarly.

3-Third Step: Add Vanilla and Dry Ingredients Mix in 1 tsp vanilla extract until combined. Sift in 2 cups (250g) all-purpose flour and ¼ tsp salt. Stir with a wooden spoon or low-speed mixer just until a dough forms; do not overmix to prevent toughness. If dough seems dry, add 1 tsp cold water. Gluten-free flour works perfectly at this stage blend thoroughly.

4-Fourth Step: Press and Shape Dough Transfer dough to the prepared pan. Press evenly with your fingers or a flat glass to about ½-inch thick. For clean edges in traditional butter shortbread recipe, chill the pan for 30 minutes. This firms the butter, making cuts precise later.

5-Fifth Step: Prick and Bake Prick the surface all over with a fork to prevent puffing and ensure even baking. Bake for 30-35 minutes until edges are pale golden, not brown. Rotate pan halfway for uniform color. Low-calorie versions may need 2-3 extra minutes.

6-Sixth Step: Cool and Cut Remove from oven and cool in pan for 10 minutes. Score into fingers or wedges with a sharp knife while warm. Cool completely on a wire rack. Full cooling prevents crumbling. Similar techniques appear in classic recipes like this shortbread cookies guide.

7-Final Step: Finishing Touches and Serving Dust with powdered sugar if desired. Serve at room temperature with tea or coffee. Store as noted below. These steps guarantee success for beginners and pros, with adaptations for every diet.
