Step‑by‑Step Instructions for Peanut Butter Cookie Bars
Step 1: Prepare the Pan
Start by lightly greasing a 9 x 13 inch baking pan with butter or nonstick spray. Then, line the bottom and long sides of the pan with parchment paper, allowing some overhang; this will make lifting out the Peanut Butter Cookie Bars much easier later.
Step 2: Preheat the Oven
Preheat your oven to 350°F (175°C) and position the rack in the center. This temperature is perfect for baking your bars evenly, giving them that delightful golden edge while keeping the center soft.
Step 3: Combine the Wet Ingredients
In a large mixing bowl, whisk together the melted butter and creamy peanut butter until the mixture is smooth and well combined. Next, add both sugars, continuing to whisk until the mixture becomes glossy. Incorporate the eggs one at a time, whisking after each addition, then stir in the vanilla extract for that extra layer of flavor.
Step 4: Mix the Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. This step is crucial for ensuring all the dry ingredients are evenly distributed and ready to create the perfect texture in your Peanut Butter Cookie Bars.
Step 5: Combine Wet and Dry
Gently add the dry mixture to the wet mixture and fold until just combined, taking care not to overmix. The goal is to create a thick batter that combines all the flavors while retaining a little texture, so you’re just one step closer to those delicious Peanut Butter Cookie Bars.
Step 6: Fold in the Chocolate
Add both the semi-sweet and white chocolate chips to the batter, folding them in until they are evenly distributed throughout. This will infuse your bars with delightful pockets of gooey chocolate goodness, making every bite a treat to remember.
Step 7: Press the Dough into the Pan
Scoop the dough into the prepared baking pan and press it firmly into the corners using a spatula or your hands. Make sure the surface is flat and even, which will help your Peanut Butter Cookie Bars bake uniformly.
Step 8: Add the Valentine Candies and Sprinkles
Take about half to two-thirds of the Valentine-colored M&M’s and gently press them into the surface of the dough. For an extra festive touch, sprinkle with Valentine sprinkles to make these treats even more inviting and vibrant.
Step 9: Bake
Place the pan in the preheated oven and bake for 18 to 24 minutes. Start checking at the 18-minute mark; the edges should look golden, while the center may still jiggle slightly. This ensures a perfectly chewy texture once cooled.
Step 10: Add Remaining Candies
Immediately after removing the pan from the oven, press any reserved M&M’s into the bare spots. This will ensure those colorful treats are front and center, making your Peanut Butter Cookie Bars both charming and delicious.
Step 11: Cool Completely
Allow the bars to cool in the pan for at least 1 to 1½ hours. This step is essential for the bars to firm up; once cooled, use the parchment overhang to lift them out of the pan for easy slicing.
Step 12: Optional White Chocolate Drizzle
For an elegant finish, melt the additional white chocolate chips with the neutral oil in the microwave until smooth. Drizzle this mixture over the cooled bars, adding extra sprinkles while the chocolate is still warm to create a beautiful presentation.
Step 13: Slice and Serve
Once your Peanut Butter Cookie Bars are completely cool, slice them into squares or rectangles, wiping the knife between cuts for clean edges. This will keep them looking as delightful as they taste.
Step 14: Storage
Store any leftovers in an airtight container at room temperature for up to 3–4 days, or refrigerate for up to a week. For longer storage, freeze them for up to 2 months—perfect for when a craving strikes!

Expert Tips for Peanut Butter Cookie Bars
Perfect Consistency: Make sure your butter is slightly cooled before mixing; hot butter can alter the texture and make your bars oily.
Room Temperature Eggs: Always use eggs at room temperature; they incorporate better for a smoother batter, ensuring consistent baking.
Don’t Overmix: Gently fold dry ingredients into the wet for just the right texture—overmixing can lead to dense bars instead of soft, chewy Peanut Butter Cookie Bars.
Check for Doneness: Keep an eye on your bars while baking; a slight jiggle in the center indicates they’re perfectly baked. Overbaking can result in dry bars.
Creative Toppings: Feel free to get creative with mix-ins like nuts or cookies pieces for some added crunch and flavor variation!

Peanut Butter Cookie Bars Recipe FAQs
How do I choose the right peanut butter for this recipe?
Absolutely! For the best results, go for creamy peanut butter that is not labeled as "natural." Natural peanut butter tends to separate and can affect the texture of your bars, making them less creamy. Look for a brand where the oils are mixed in well, as this will provide a smooth and consistent batter.
What is the best way to store leftover Peanut Butter Cookie Bars?
To keep your Peanut Butter Cookie Bars fresh and delicious, store them in an airtight container at room temperature for up to 3–4 days. If you'd like to preserve them for longer, stick them in the fridge where they'll stay tasty for up to a week. Just remember to allow them to come back to room temperature before digging in for the best experience!
Can I freeze Peanut Butter Cookie Bars?
Of course! Freezing these bars is super easy. First, wrap each bar tightly in plastic wrap and then place them in a freezer-safe container or resealable bag. They can be frozen for up to 2 months. When you're ready to indulge, simply thaw them in the fridge overnight before enjoying. For a quick fix, a few seconds in the microwave can make them gooey and delightful again!
What if my Peanut Butter Cookie Bars turn out too dry?
Very! If you find that your bars are dry, it could be due to overbaking. Aim for that slight jiggle in the middle when baking; this ensures a soft texture. If they are already baked, try warming them slightly in the microwave with a damp paper towel for added moisture. Next time, keep a close eye on the timer—every oven is different!
Are Peanut Butter Cookie Bars safe for dog consumption?
It's best to avoid giving your beloved pooch any Peanut Butter Cookie Bars. While peanut butter itself is safe in small amounts for dogs, the added sugars, chocolate, and candies can be harmful. Instead, consider dog-friendly treats you can whip up for your furry friend, ensuring they get their own special snack without the risks!
Can I substitute ingredients for dietary restrictions?
Absolutely! If you need a gluten-free option, you can substitute all-purpose flour with a 1:1 gluten-free flour blend. For a dairy-free version, use a plant-based butter and swap out the chocolate chips for dairy-free varieties. Plus, if you're looking to reduce sugar, you might try lighter sweeteners like maple syrup, but adjust the wet ingredients accordingly. The more the merrier when it comes to making these Peanut Butter Cookie Bars suitable for everyone!
