What Ingredients are in Peanut Butter Cookie Bars?
These peanut butter cookie bars come together with simple, wholesome ingredients that you probably have in your kitchen.
As a busy dad who needs to please three little critics at home, I’ve found this recipe to be perfect because it uses pantry staples that create something truly special. The combination of creamy peanut butter with just the right amount of sweetness makes these bars irresistible without requiring a special trip to the store.
- 1 cup creamy peanut butter (local Wisconsin brand if possible)
- ½ cup unsalted butter, softened
- 1 cup brown sugar (packed)
- ½ cup granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- 2 tablespoons Wisconsin honey
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon salt
- 1 cup chocolate chips (optional, but who are we kidding?)
When selecting your ingredients, quality matters in a recipe this simple.
I recommend using natural peanut butter without added sugars or oils, although any creamy variety will work. For a truly farm-to-table approach, sourcing local Wisconsin honey adds a distinctive flavor that store-bought varieties can’t match.
And while the chocolate chips are technically optional, my daughters would stage a small revolution if I left them out.
Feel free to substitute with whatever mix-ins your family enjoys—chopped peanuts, toffee bits, or even some dried Wisconsin cranberries could add wonderful texture and flavor variations.
How to Make These Peanut Butter Cookie Bars
Let’s get our hands dirty with these irresistible peanut butter cookie bars! Start by preheating your oven to 350°F and lining a 9×13-inch baking pan with parchment paper.
In a large bowl, cream together 1 cup of creamy peanut butter (preferably from a local Wisconsin producer) and ½ cup of softened unsalted butter until smooth and well combined. Add in 1 cup of packed brown sugar and ½ cup of granulated sugar, mixing until the mixture becomes light and fluffy. This usually takes about 2-3 minutes with an electric mixer, or a bit longer if you’re building those arm muscles by hand.
Next, incorporate 2 large eggs one at a time, beating well after each addition. The eggs help bind everything together while adding moisture to our bars. Stir in 2 teaspoons of vanilla extract and 2 tablespoons of Wisconsin honey—the honey adds a complexity that refined sugar alone can’t deliver.
In a separate bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking powder, and ½ teaspoon of salt. Gradually add this dry mixture to your wet ingredients, folding gently until just combined. Over-mixing here can make your bars tough, and nobody wants that.
Fold in 1 cup of chocolate chips (my daughters’ non-negotiable addition), then spread the dough evenly into your prepared pan.
Bake for 20-25 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out with a few moist crumbs—not wet batter. Remember, these are cookie bars, not cake, so a slight underbake creates that perfect chewy texture we’re after.
Let them cool completely in the pan before cutting into squares. Trust me on the cooling part; I know it’s tempting to dig in right away (especially with three impatient critics hovering nearby), but patience rewards you with clean-cut bars that hold their shape.
These beauties will stay fresh in an airtight container for up to 5 days, though they’ve never lasted more than 48 hours in my household.
