Description
These Soft Peanut Butter Cookies are quick, simple, and the best sweet treat for any holiday, party, or weeknight dessert craving! What makes this version so special is the extra egg yolk and brief bake time, which creates an ultra-tender texture that stays soft for days. With classic fork criss-cross marks and a rich buttery peanut flavor, these easy cookies are a healthy-ish family favorite that everyone will request again and again.
Ingredients
Scale
- 0.5 cup unsalted butter
- 1 cup creamy peanut butter
- 0.5 cup granulated sugar
- 0.5 cup light brown sugar
- 1 large egg
- 1 large egg yolk
- 1 teaspoon pure vanilla extract
- 1.5 cups all-purpose flour
- 0.75 teaspoon baking soda
- 0.5 teaspoon fine sea salt
Instructions
- Add 1/2 cup softened unsalted butter, 1 cup conventional creamy peanut butter, 1/2 cup granulated sugar and 1/2 cup packed light brown sugar to a mixing bowl. Beat on medium speed for exactly 2 minutes at room temperature (around 70°F) until light, fluffy and pale tan in color. You’ll hear the mixer motor ease up as the mixture lightens and see the granular sugars dissolve into the fats. Scrape down the sides once at the 1-minute mark to ensure no dense butter pockets remain. (I tried using natural drippy peanut butter during my first test batch, the oil separated completely and left greasy puddles. Stick to standard processed peanut butter like Skippy or Jif for the right emulsion.) Creaming builds the airy fat base that gives these soft peanut butter treats their melt-in-your-mouth crumb.
- Add 1 large room-temperature egg, 1 large egg yolk and 1 teaspoon pure vanilla extract to the creamed mixture. Beat on medium-low speed for 45 seconds until completely smooth and glossy. The pale mixture will darken slightly and loosen into a silky, uniform batter. You’ll smell the warm vanilla instantly as it blends with the roasted nut aroma. Don’t overbeat past 60 seconds here or you’ll whip excess air into the eggs, which creates cakey cookies instead of dense soft peanut butter bites.
- Sift 1.5 cups all-purpose flour, 3/4 teaspoon baking soda and 1/2 teaspoon fine sea salt together. Pour into the wet bowl and fold gently using a rubber spatula in a J-shaped motion for about 30 seconds until no white streaks remain. The dough will shift from liquid batter into a thick, tacky dough that pulls away cleanly from the sides of the bowl. Stop as soon as the last speck of flour disappears. Overworking gluten at this stage makes the final Soft Peanut Butter Cookies tough and dry rather than soft.
- Scoop dough into 1.5-inch balls (about 2 tablespoons each) and place 2 inches apart on a parchment-lined sheet pan. Dip a fork in granulated sugar and press down gently in a crosshatch pattern, flattening each ball to about 1/2-inch thickness. You will see clean crosslines pressed into the top and slight natural cracks along the outer edges of each round disc. (I tried skipping the sugar dip on the fork, the metal stuck to the sticky dough and ruined the shape every time.) Flattening the balls manually ensures even baking since high-fat peanut butter dough does not spread much on its own.
- Bake at 350°F in a preheated oven for exactly 9 to 10 minutes until the edges are light golden and the centers still look slightly soft and underbaked. Remove from the oven and let rest on the hot pan for 10 minutes off the heat. The cookies will puff slightly, and the centers will set into a soft, velvety texture as residual heat carries over on the warm sheet. You’ll smell rich roasted peanut butter filling the whole kitchen. Pull them out right at minute 9, leaving them in until the centers look fully done will make them crispy instead of soft.
Notes
Pro Tips:
- Bake at 350°F for exactly 9 minutes, the centers should look slightly soft when pulled from the oven.
- Use commercial peanut butter brands like Jif or Skippy because natural oils separate and cause dough spreading.
- Add an extra egg yolk to boost fat content and keep the baked texture pillowy for days.
- Dip your fork in granulated sugar before pressing crosshatch patterns to prevent sticky dough tearing.
- Leave cookies on the hot baking pan for 10 minutes off heat to complete carryover baking gently.
- Spoon and level your all-purpose flour into measuring cups to avoid adding excess flour.
Storage: Store baked Soft Peanut Butter Cookies in an airtight container at room temperature with a slice of white bread for up to 5 days. The bread releases subtle moisture that keeps the cookie crumb soft without altering flavor. To freeze raw dough, place fork-pressed dough balls on a tray until solid, then transfer to a freezer bag for up to 3 months. Bake straight from frozen at 350°F for 10 to 11 minutes total.
