1-First Step: Gather and Prep Ingredients Start your mise en place to keep things smooth. Measure 1 cup softened butter, 1 cup brown sugar, 1/2 cup white sugar, 2 eggs, and 1 tsp vanilla. In another bowl, combine 1 1/2 cups flour, 1 tsp baking soda, 1 tsp cinnamon, and 3 cups rolled oats. Plump 1 cup raisins in hot water for 5 minutes if dry, then drain. This prep takes 10 minutes and prevents rushed mistakes.

2-Second Step: Cream Butter and Sugars Beat softened butter, brown sugar, and white sugar together until light and fluffy, about 2-3 minutes with a mixer. Scrape sides often for even mixing. This incorporates air for soft centers in your homemade oatmeal raisin cookies.

3-Third Step: Add Wet Ingredients Mix in 2 eggs one at a time, beating well after each. Add 1 tsp vanilla extract. The mixture should look smooth and creamy. Beat on medium speed for 1 minute to fully emulsify.

4-Fourth Step: Combine Dry Ingredients Gently stir dry mix into wet in three additions. Use a spatula to fold until just combined, avoiding overmixing. Dough will be thick and sticky.

5-Fifth Step: Fold in Raisins and Chill Add 1 cup raisins, stirring gently. Cover dough and chill 30 minutes to 1 hour. Chilling firms butter, preventing spread for thicker cookies.

6-Sixth Step: Preheat and Prep Baking Sheets Heat oven to 350°F. Line sheets with parchment paper. This temp bakes edges crisp while centers stay soft.

7-Seventh Step: Scoop and Shape Dough Scoop tablespoon-sized balls, spacing 2 inches apart. Flatten slightly if desired for even baking. One sheet fits 12 cookies.

8-Eighth Step: Bake to Perfection Bake 10-12 minutes until edges golden but centers soft. Rotate sheets halfway. Avoid overbaking for chewiness.

9-Final Step: Cool and Store Cool on sheet 5 minutes, then transfer to rack. Store in airtight container. Enjoy warm or at room temp.
