Thick And Chewy Peanut Butter Cookies Recipe

I never met a peanut butter cookie this thick, chewy, and melt-in-your-mouth rich without a fussy ingredient list. One bite and you’ll see why these disappear faster than any cookie on the plate.

I’m obsessed with these thick and chewy peanut butter cookies because they hit that sweet spot between rich, soft, and seriously satisfying. The centers stay tender, the edges have just enough bite, and the peanut butter flavor actually shows up instead of whispering from the background.

I love how creamy peanut butter gives them that bold, nutty punch, while light brown sugar keeps every bite chewy and deep. But the best part?

They taste like the cookie I always hope I’m getting from a bakery case. Big, soft, a little craggy, and impossible for me to stop picking at them.

Ingredients

• All-purpose flour gives the cookies structure, so they’re thick instead of floppy.
• Cornstarch keeps the centers soft and chewy, like bakery-style cookies.
• Baking soda helps them spread just enough and get those classic crinkly edges.
• Baking powder adds a little lift, so they don’t feel too dense.
• Salt balances the sweetness and makes the peanut butter taste way better.
• Butter brings rich flavor and that soft, melt-in-your-mouth bite.
• Creamy peanut butter is the star, with big nutty flavor in every bite.
• Brown sugar keeps them moist, chewy, and a little caramel-like.
• Granulated sugar adds sweetness and helps the edges get lightly crisp.
• Eggs hold everything together and make the cookies feel sturdy.
• Vanilla adds warmth.

  Basically, it makes the whole cookie taste more homemade.

Ingredient Quantities

• 2 1/4 cups (280 g) all purpose flour
• 2 tablespoons cornstarch
• 1 teaspoon baking soda
• 1/2 teaspoon baking powder
• 1/2 teaspoon salt
• 1 cup (226 g) unsalted butter, softened
• 1 cup (240 g) creamy peanut butter
• 1 1/4 cups (250 g) packed light brown sugar
• 1/2 cup (100 g) granulated sugar
• 2 large eggs, at room temperature
• 2 teaspoons vanilla extract

How to Make this

1. Preheat oven to 350°F (175°C) and line two baking sheets with parchment paper.

2. Whisk together 2 1/4 cups (280 g) all purpose flour, 2 tablespoons cornstarch, 1 teaspoon baking soda, 1/2 teaspoon baking powder, and 1/2 teaspoon salt in a medium bowl.

3. In a large bowl, beat 1 cup (226 g) softened unsalted butter, 1 cup (240 g) creamy peanut butter, 1 1/4 cups (250 g) packed light brown sugar, and 1/2 cup (100 g) granulated sugar until light and creamy, about 2 to 3 minutes.

4. Add 2 large room temperature eggs one at a time, mixing well after each, then stir in 2 teaspoons vanilla extract until combined.

5. Gradually add the dry ingredients to the wet mixture and mix on low speed just until a soft dough forms, scraping the bowl as needed.

6. Chill the dough in the refrigerator for 30 to 60 minutes to firm up and prevent excessive spreading.

7. Scoop rounded tablespoons or use a
1.5 tablespoon cookie scoop to portion dough, roll into balls, and place about 2 inches apart on the prepared baking sheets.

8. Optional for classic peanut butter cookie appearance: press each ball gently with the back of a fork to create a crisscross pattern, without flattening too thin.

9. Bake for 10 to 12 minutes, until edges are set and centers still look slightly soft. Cool on the baking sheet for 5 minutes, then transfer to a wire rack to finish cooling.

Equipment Needed

1. Oven
2. Two rimmed baking sheets lined with parchment paper

6. Measuring cups and spoons and kitchen scale for grams
7. 1.5 tablespoon cookie scoop or tablespoon and small scoop for rolling
8. Fork for crisscross pattern and a bench scraper or spoon for portioning
9. Wire cooling rack and refrigerator space for chilling dough

Thick And Chewy Peanut Butter Cookies Recipe Substitutions and Variations

• All purpose flour: Substitute with a 1-to-1 gluten free all purpose flour blend (280 g) that contains xanthan gum for structure. No other recipe changes required.
• Unsalted butter: Use solid coconut oil measured 1-to-1 (226 g) but chill the dough slightly before baking to prevent spreading. For a dairy free option use vegan stick butter 1-to-1.
• Creamy peanut butter: Swap with almond butter or sunflower seed butter 1-to-1 (use sunflower for nut allergies). If the alternative is oilier, chill the dough for 15 to 30 minutes before baking.
• Eggs: Replace each large egg with 1 tablespoon ground flaxseed mixed with 3 tablespoons water, set 5 minutes to gel. For two eggs use 2 tablespoons flax + 6 tablespoons water; expect slightly denser cookies.

Pro Tips

1) Chill the dough until it feels firm to the touch, not just cool. A longer chill, up to 2 hours, helps the cookies hold their shape and develop more flavor.

2) Don’t overmix once the flour is added. Mix just until combined so the cookies stay tender and do not become tough.

3) Use a creamy peanut butter with good peanut flavor and not too oily. If your peanut butter is very runny, pop it in the fridge for 10 minutes so the dough consistency stays right.

4) Press with a fork gently to make the crisscross pattern. Pressing too hard will flatten the cookies too much, so aim for a light, even impression.

5) Watch the baking time closely and pull the cookies when the edges are set but centers still look slightly soft. They will continue to set as they cool and will be more tender than if baked until fully firm. Store in an airtight container with a slice of bread to keep them soft.
