  • Eggs: Bind everything together and provide structure.
  • Vanilla Extract: A dash of vanilla makes everything come together beautifully, adding warmth to the flavor.
  • Raisins: Of course, the raisins are the star here, adding a touch of sweetness and chewiness.

Instructions Let’s jump into the steps to make these oatmeal raisin cookie bars. Trust me, they’re simple!

  1. Preheat Your Oven: Set your oven to 350°F (175°C). Preheating ensures that your bars bake evenly and turn out perfectly golden.
  2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, cinnamon, and salt. Set aside.
  3. Cream Butter and Sugar: In a large bowl, beat together the butter, granulated sugar, and brown sugar until light and fluffy. This step is crucial for the soft texture of your bars.
  4. Add Eggs and Vanilla: Beat in the eggs, one at a time, then stir in the vanilla extract. This makes the batter smooth and rich.
  5. Combine Wet and Dry Ingredients: Gradually add the dry mixture to the wet ingredients, stirring just until combined. Be careful not to overmix—this keeps the bars tender.
  6. Add Oats and Raisins: Stir in the rolled oats and raisins (and any optional add-ins). You want everything evenly distributed without overworking the dough.
  7. Prepare the Baking Dish: Grease or line an 8×8-inch baking dish with parchment paper. This makes cleanup a breeze and helps the bars come out perfectly.
  8. Assemble and Bake: Spread the batter evenly into the prepared dish. Bake for 25-30 minutes, or until the edges are golden and a toothpick inserted into the center comes out clean.
  9. Cool and Slice: Let the bars cool completely in the pan before slicing them into squares. The cooling process lets the flavors set, making them even more delicious.

How to Serve Oatmeal Raisin Cookie Bars
