Valentine Peanut Butter Heart Cookie Bars
Valentine Peanut Butter Heart Cookie Bars
  • * 3/4 cup butter, softened
  • * 1/2 cup peanut butter (creamy or crunchy – your preference!)
  • * 1/2 cup granulated sugar
  • * 1/2 cup packed light brown sugar
  • * 2 large eggs
  • * 1 teaspoon vanilla extract
  • * 2 1/2 cups all-purpose flour
  • * 1 Tablespoon cornstarch
  • * 1 teaspoon baking soda
  • * 6 Tablespoons Valentine’s sprinkles, divided (red, white, and pink)
  • * 1/2 cup Valentine’s M&M’s
  • * 2 bags Reese’s peanut butter hearts (chocolate & white chocolate)

Step-by-Step Instructions

  • 1. Preheat & Prep: Preheat your oven to 350°F (175°C). Grease and line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides. This will make removing the bars a breeze!
  • 2. Cream the Butter & Sugars: In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy. An electric mixer works best for this, but you can absolutely do it by hand with some elbow grease.
  • 3. Add Peanut Butter & Eggs: Beat in the peanut butter until well combined. Then, add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
  • 4. Combine Dry Ingredients: In a separate bowl, whisk together the flour, cornstarch, and baking soda. This ensures the baking soda is evenly distributed, which helps with the rise.
  • 5. Gradually Add Dry Ingredients: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix, as this can result in tough bars.
  • 6. Press into Pan: Press the dough evenly into the prepared baking pan. A lightly floured spatula or the back of a spoon helps with this.
  • 7. Bake: Bake for 20-25 minutes, or until the edges are golden brown and the center is set. Begin checking for doneness at 20 minutes.
  • 8. Sprinkle with Love: While the bars are still warm, immediately sprinkle 4 Tablespoons of the Valentine’s sprinkles evenly over the top. Gently press the sprinkles into the dough.
  • 9. Add Candies: Scatter the Valentine’s M&M’s and Reese’s peanut butter hearts over the sprinkled surface. Press them lightly into the warm dough so they adhere. For an extra touch, save 2 tablespoons of sprinkles to add after cutting the bars.
  • 10. Cool & Cut: Let the bars cool completely in the pan before lifting them out using the parchment paper overhang. Once cooled, cut into squares or, for the festive touch, use a heart-shaped cookie cutter to create heart-shaped bars.

Chef’s Tip: Don’t have time to cut individual hearts? Simply cut squares and decorate them with a small dollop of frosting and a single Reese’s heart!

Why This Recipe Works & Expert Tips

This recipe works because it strikes a perfect balance between simplicity and flavor. The combination of peanut butter and both granulated and brown sugar creates a wonderfully chewy texture and a depth of sweetness.

The addition of cornstarch helps to tenderize the bars even further, resulting in a melt-in-your-mouth experience. Using the parchment paper sling is crucial for easy removal – trust me on this one!

For a truly stunning presentation, consider layering the sprinkles – a base of pink, then white, and finally a scattering of red. The Reese’s hearts not only look adorable but also add an extra burst of peanut butter and chocolate.

This is easy comfort food for family dinners or a simple sweet treat that’s sure to be appreciated. For a more intense peanut butter flavor, use a natural-style peanut butter (the kind you need to stir).

Storage, Freezing, and Reheating Tips

These Valentine Peanut Butter Heart Cookie Bars are best enjoyed fresh, but they can be stored in an airtight container at room temperature for up to 3 days. For longer storage, you can freeze them. To freeze, place the bars in a single layer on a baking sheet and freeze for about an hour, or until solid.

Then, transfer them to a freezer-safe bag or container. They will keep in the freezer for up to 2 months. To reheat, simply thaw at room temperature or warm briefly in a microwave. While they’re delicious chilled, a slightly softened bar brings out even more of the peanut butter flavor. Sharing these Valentine’s baking creations is a breeze, too – pack extras for friends and family!

These Valentine Peanut Butter Heart Cookie Bars are surprisingly simple! Start by creaming together butter and sugars, then add peanut butter, eggs, and vanilla. Mix in the dry ingredients, press the dough into a lined baking pan, and bake until golden brown.

The key to the Valentine’s theme is sprinkling with red, white, and pink sprinkles and adding Valentine’s M&M’s and Reese’s peanut butter hearts while the bars are still warm. For extra heart shape, use a heart shaped cookie cutter after cooling. This creates a festive and delicious peanut butter dessert perfect for the holiday!

There are a couple of ways! The easiest is to bake the bars in a rectangular pan and then use a heart-shaped cookie cutter to cut out individual heart-shaped bars after they’ve cooled. Alternatively, you can invest in a heart-shaped baking pan.

Press the dough evenly into the pan, and once baked, you’ll have a large heart-shaped bar that you can then cut into slices. The cutting method is preferable for ease – the recipe is written for a 9×13 and cutting shapes after is the easiest way to ensure a decorative Valentine’s treat!

What kind of peanut butter is best?

You can use either creamy or crunchy peanut butter – it’s entirely a matter of personal preference! For a smoother texture, creamy peanut butter works best. If you enjoy a bit of crunch, go with crunchy. Conventional or natural peanut butter will also both work, though natural peanut butter (the kind that separates) might require a little extra mixing to incorporate it fully into the dough.

When looking for the best peanut butter dessert flavor, try to use a peanut butter you genuinely enjoy the taste of, as it will shine through in the final product.

Can I add chocolate to these bars?

Absolutely! There are several ways to incorporate chocolate. You could melt some chocolate chips and swirl them into the dough before baking. Or, drizzle melted chocolate over the cooled bars. For an even more decadent treat, consider using chocolate peanut butter instead of regular peanut butter.

The combination of peanut butter and chocolate is a classic for a reason, and it will take these Valentine’s bars to the next level. Feel free to experiment with different types of chocolate – milk, dark, or white – to find your perfect match for this Valentine peanut butter dessert!

I hope you enjoy making these Valentine Peanut Butter Heart Cookie Bars as much as my family does! They’re a fun, easy, and delicious way to show someone you care. Don’t be afraid to get creative with the sprinkles and candies – personalize them to reflect your loved one’s favorite colors and treats.

These bars also freeze well – wrap individually and store in a freezer-safe bag for up to 2 months.
