Ingredients
- ½ cup unsalted butter, softened
- ½ cup creamy peanut butter
- 1 large egg
- 1 cup light brown sugar
- 1 tablespoon pure vanilla extract
- 1 cup all-purpose flour
- 1 cup Valentine’s M&M’s
- ¾ cup Valentine’s sprinkles
Mixing the Batter

In a large bowl, combine ½ cup of softened unsalted butter, ½ cup of creamy peanut butter, 1 cup of light brown sugar, 1 tablespoon of pure vanilla extract, and 1 large egg. Beat together until the mixture is smooth and fully combined. You want that lovely swirl of peanut butter and sugar dancing together!
Incorporating the Dry Ingredients
Gradually add 1 cup of all-purpose flour into the wet mixture. Mix until the flour is fully incorporated and a soft dough begins to form. Just keep it gentle so your bars stay soft.
Adding Fun Mix-Ins
Gently fold in ¾ cup of Valentine’s M&M’s and ½ cup of Valentine’s sprinkles into your cookie dough. It’s all about ensuring an even distribution for those delightful bursts of color and flavor.
Preparing the Baking Pan
Preheat your oven to 350°F (175°C). Next, line a 9×9-inch baking pan with parchment paper. This step makes removing the bars after baking super easy! Let that parchment hang over the sides a bit – it’s like a little handle for you later.
Spreading the Dough
Transfer the cookie dough into the prepared baking pan. Use a spatula to press it evenly into the pan, smoothing the top for an even bake. Make sure it’s nice and level so every piece cooks just right.
Topping Off
Sprinkle the remaining ¼ cup of Valentine’s M&M’s and ¼ cup of sprinkles on top of the dough. Press them gently into the surface for a decorative finish. Just imagine how pretty these will look when they come out of the oven!
Baking to Perfection
Place the baking pan into the oven and bake for 24-26 minutes. Keep an eye on them! A toothpick inserted in the center should come out clean, signaling that deliciousness is on the way.
Cooling and Slicing
Once baked, remove from the oven and allow the bars to cool completely in the pan. Remember to use the parchment overhang to lift the bars out for easy slicing into squares or rectangles. It’s always fun to see those neat edges and vibrant colors!
Serving Suggestions
These Valentine Peanut Butter Cookie Bars are perfect served as is or warmed slightly. Pair them with a scoop of vanilla ice cream or a dollop of whipped cream for an indulgent treat. It elevates the sweetness to a whole new level!
Tips for Success
- Ensure your butter is soft, not melted. This helps achieve the right dough consistency.

Variations
Feel free to get creative! Substitute white chocolate chips for the M&M’s for a different flavor profile. Add chopped nuts or crushed graham crackers for extra crunch and texture. You could also experiment with various kinds of festive sprinkles for every occasion.
