Step‑by‑Step Instructions for Peanut Butter Cookie Bars
Step 1: Prepare the Baking Pan
Start by lightly greasing a 9 x 13 inch baking pan with butter or nonstick spray. Then, lay parchment paper into the pan, making sure to leave an overhang to aid in lifting the bars later. Give the parchment a light grease as well to prevent sticking, and set the prepared pan aside while you preheat your oven.
Step 2: Preheat the Oven
Preheat your oven to 350°F (175°C) and adjust the rack to the center position. This temperature is crucial for achieving the ideal texture of your Peanut Butter Cookie Bars, so make sure the oven is fully heated before baking ensures even cooking.
Step 3: Mix the Wet Ingredients
In a large mixing bowl, combine melted butter and creamy peanut butter using a whisk until the mixture is perfectly smooth. Gradually add in both the light brown and granulated sugars, whisking until the mixture becomes thick and glossy. Incorporate the eggs one at a time, whisking well after each addition, followed by the pure vanilla extract for depth of flavor.
Step 4: Combine the Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and fine sea salt. This dry mix will provide the structure for your bars, so make sure all the ingredients are well blended before moving on to the next step.
Step 5: Fold the Mixtures Together
Gently add the dry ingredients into the wet mixture using a spatula or wooden spoon. Carefully fold the mixtures together until just combined, taking care to stop as soon as no dry streaks remain, ensuring your Peanut Butter Cookie Bars are soft and chewy.
Step 6: Add the Chocolate Chips
Sprinkle the semi-sweet and white chocolate chips over the combined dough. Using your spatula, gently fold them in until they are evenly distributed throughout the batter, adding delicious pockets of chocolate in each bite of your delicious bars.
Step 7: Spread the Dough into the Pan
Transfer the cookie dough into your prepared baking pan. Using a spatula or lightly greased hands, press the dough firmly into the edges and corners of the pan, ensuring a smooth, even surface. This step is important for an evenly baked product that’s easy to slice later.
Step 8: Add Festive Toppings
Press half to two-thirds of the Valentine M&M’s into the surface of the dough, allowing them to stick beautifully. If desired, sprinkle Valentine sprinkles on top for a festive touch, reserving any remaining M&M’s for post-baking decoration.
Step 9: Bake the Cookie Bars
Bake your Peanut Butter Cookie Bars in the preheated oven for 18 to 24 minutes, checking for doneness starting at the 18-minute mark. The edges should be lightly golden, while the center may still jiggle slightly. A toothpick inserted into the center should come out with a few moist crumbs for that perfect chewy texture.
Step 10: Finishing Touches
Once out of the oven, immediately press the reserved M&M’s into any bare spots on top of the bars, giving them an eye-catching finish. If desired, sprinkle flaky sea salt on top, enhancing the flavor while creating a delightful contrast to the sweet.
Step 11: Cool and Slice
Allow the bars to cool in the pan for at least 1 to 1½ hours for them to set properly. If you prefer extra-fudgy bars, chill them in the refrigerator for 30 to 45 minutes before lifting them out using the parchment overhang and slicing into squares or rectangles.
Step 12: Optional Drizzle
For a delightful drizzle, combine the white chocolate chips and neutral oil in a microwave-safe bowl. Heat in 15–20 second bursts until the mixture is smooth. Drizzle generously over the cooled Peanut Butter Cookie Bars and scatter remaining sprinkles for that festive flair.
Step 13: Storage Tips
Store your cooled Peanut Butter Cookie Bars in an airtight container at room temperature for up to 3–4 days. For longer freshness, refrigerate for up to a week or freeze individual bars for up to 2 months, ensuring delicious treats are always at hand!

Expert Tips for Peanut Butter Cookie Bars
Perfect Peanut Butter: Use creamy peanut butter that’s well-stirred, avoiding natural varieties. This ensures a smooth texture and consistent flavor in your bars.
Sweet Success: Don’t skip weighing your brown sugar—packing it is essential for the right sweetness and moisture balance in the Peanut Butter Cookie Bars.
Mix Gently: Fold the dry ingredients into the wet slowly to avoid overmixing. This preserves the chewy texture, preventing a dense final product.
Watch the Oven: Start checking for doneness at 18 minutes. Overbaking can result in a dry cookie bar, while underbaking will keep them delightfully chewy!
