When the afternoon slump hits, sometimes you just need something chewy and comforting without the fuss. These gluten free peanut butter cookie bars come together fast, with a few pantry staples that you probably already have. They’re the kind of treat that’s easy to pull out of the oven and hard to resist once it’s cooled just enough to hold their shape but still melt in your mouth.
I remember the first time I made these bars, I was halfway through a hectic day and craving something peanut buttery and sweet but without a complicated recipe. The kitchen was a little messy—there was a smear of peanut butter on my sleeve, and I couldn’t find the mixing bowl I usually use, so I grabbed a slightly smaller one. Even with that minor hiccup, the smell of baking peanut butter filled the room so warmly I almost forgot I was rushing. When they came out golden and soft, I let one cool just a bit, then took a bite. The chewy texture caught me off guard—in the best way—and that nutty flavor was just right. Not too sweet, not too dense, just comforting. I probably ate more than I should have before dinner, but hey, sometimes that’s the point.

Description
Delicious and chewy gluten free peanut butter cookie bars made with simple ingredients. Perfect for a quick dessert or snack, these bars are naturally gluten free and packed with rich peanut butter flavor.
Ingredients
1 cup creamy peanut butter
1 cup granulated sugar
1 large egg
1 teaspoon vanilla extract
1/2 teaspoon baking soda
1/4 teaspoon salt
Instructions
Preheat the oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving an overhang on the sides for easy removal.
In a large mixing bowl, combine the peanut butter and granulated sugar. Stir until smooth and creamy.
Add the egg and vanilla extract to the peanut butter mixture and mix until fully incorporated.
Sprinkle the baking soda and salt over the mixture and stir until just combined.
Spread the batter evenly into the prepared baking pan, smoothing the top with a spatula.
Bake in the preheated oven for 18-20 minutes, or until the edges are lightly golden and the center is set.
Remove from the oven and allow the bars to cool completely in the pan on a wire rack.
Once cooled, use the parchment paper overhang to lift the bars out of the pan and cut into 16 squares.

In my kitchen, I usually just line the pan with parchment paper and call it a day—makes cleanup easier and helps the bars lift out smoothly. These bars are fantastic on their own but also pair well with a cold glass of milk or a cup of coffee. I’ve tried stirring a pinch of cinnamon in once or twice, which gave a nice warm twist, but I haven’t tested many other variations yet. Sometimes I add a few chocolate chips on top right before baking, but that’s just me experimenting. If you want to keep it classic, these bars shine all by themselves.
FAQ
Can I substitute crunchy peanut butter? I haven’t tried it myself, but crunchy might add texture you’ll either love or find a bit odd. Worth experimenting if you’re feeling adventurous.
How should I store leftover bars? They keep well in an airtight container at room temperature for a few days, but refrigeration can help if your kitchen is warm.
Are these bars suitable for other dietary needs? They’re naturally gluten free, but if you have peanut allergies or other restrictions, they’re not ideal.
