Peanut Butter Shortbread Ingredients
For the Cookies
• All-Purpose Flour – Provides structure and stability for the cookies; gluten-free all-purpose flour can be used as a perfect substitute.
• Cornstarch – Helps keep the cookies soft and tender, preventing them from becoming dry and enhancing the shortbread texture.
• Salt – Enhances the overall flavor and balances the sweetness that complements the peanut butter beautifully.
• Unsalted Butter – The primary fat; it adds a rich creaminess; can be substituted with vegan butter for a delightful dairy-free version.
• Creamy Peanut Butter – Infuses flavor and a creamy texture; avoid using natural peanut butter, as its oily texture can affect the consistency of your cookies.
• Light Brown Sugar – Provides moisture and sweetness, contributing to a delightful chewy texture that pairs wonderfully with the crumbly shortbread.
• Granulated Sugar – For sprinkling on top before baking, adds a slight crunch that enhances the cookie experience.
• Optional Add-Ins – Mini chocolate chips, nuts, or spices can be included for fun and creative variations, customizing your peanut butter shortbread to your liking!
Step‑by‑Step Instructions for Peanut Butter Shortbread
Step 1: Preheat and Prepare
Begin by preheating your oven to 325°F (163°C). Line an 8-inch round cake pan with parchment paper to ensure easy removal of the cookies later. Take a moment to gather your ingredients, ensuring everything is ready to streamline the mixing process for your buttery peanut butter shortbread.
Step 2: Combine Dry Ingredients
In a small bowl, whisk together 1 cup of all-purpose flour, 1/4 cup of cornstarch, and a pinch of salt until evenly combined. Set this dry mixture aside, allowing the cornstarch to help keep your peanut butter shortbread soft and tender. This step ensures the dry ingredients are well blended before adding them to the wet mix.
Step 3: Cream Wet Ingredients
In a medium bowl, combine 1/2 cup of softened unsalted butter, 1/2 cup of creamy peanut butter, 1/2 cup of light brown sugar, and 1 teaspoon of vanilla extract. Beat these ingredients together until the mixture is creamy and smooth, which should take around 2-3 minutes. This whipped blend of flavors lays the foundation for delicious peanut butter shortbread.
Step 4: Mix Dry and Wet Ingredients
Gradually add the dry flour mixture to the creamed peanut butter mixture. Stir gently, combining the ingredients until a moist dough begins to form, around 1-2 minutes. If adding chocolate chips or nuts, fold them in at this point, ensuring an even distribution throughout your delicious cookie dough.
Step 5: Shape the Dough
Transfer the dough into the prepared cake pan and press it evenly across the bottom, smoothing out any uneven spots. Use a fork to dock the surface with small holes, which will help prevent the cookies from puffing up during baking. This step ensures your peanut butter shortbread bakes uniformly, retaining that delightful crumbly texture.
Step 6: Bake the Cookies
Place the cake pan in your preheated oven and bake for 28-30 minutes, or until the edges are lightly golden brown. Keep an eye on the cookies during the last few minutes to achieve the perfect shade. Once baked, remove from the oven and allow them to cool for about 10 minutes in the pan before transferring to a wire rack to cool completely.
Step 7: Slice and Serve
After cooling slightly, use a sharp knife to slice the peanut butter shortbread into wedges or squares while they’re still warm. This will help create clean edges. You can enjoy them warm or allow them to cool completely for a firmer texture. These cookies store beautifully, perfect for sharing or savoring on your own!

How to Store and Freeze Peanut Butter Shortbread
Storage Tips:
- Room Temperature: Keep the cookies in an airtight container at room temperature for up to 1 week. This retains their crumbly texture and delicious flavor.
- Fridge: If you prefer a firmer cookie, store them in the refrigerator in an airtight container for up to 2 weeks; just allow them to come to room temperature before enjoying.
- Freezer: For longer preservation, freeze slices of peanut butter shortbread in a single layer, separated by parchment paper. They can last up to 3 months—simply thaw at room temperature when you’re ready to indulge.
- Reheating: To enjoy warm cookies, microwave them for about 10-15 seconds, or pop them in a preheated oven at 350°F (175°C) for a few minutes, reviving their freshly-baked taste!

Expert Tips for Peanut Butter Shortbread
-
Use Room Temperature Butter: Make sure your unsalted butter is softened to room temperature for easy mixing and a creamy texture. Cold butter may result in lumps.
-
Choose the Right Peanut Butter: Stick with creamy, no-stir peanut butter for the best consistency in your cookies. Natural varieties can introduce oiliness and impact texture.
-
Don’t Overmix: Mix the dough just until it comes together to maintain a tender crumb. Overmixing might lead to drier cookies as it develops the gluten.
-
Watch the Baking Time: Keep a close eye on the cookies during the last few minutes of baking to ensure they don’t overbrown. Perfectly baked shortbread should be lightly golden.
-
Storing Wisely: Allow cookies to cool completely before storing in an airtight container at room temperature. This helps maintain freshness for up to one week.
-
Feel Free to Customize: Add-ins like chocolate chips or nuts can offer a delicious twist to your classic peanut butter shortbread. Experiment with flavors you love!

Peanut Butter Shortbread Cookies Recipe FAQs
How do I choose the right peanut butter for this recipe?
Absolutely! For the best results, use a creamy, no-stir peanut butter, which offers a smooth consistency that blends well with other ingredients. Avoid natural peanut butter types, as their oily nature can affect the texture of your cookies, making them too soft or greasy. The right peanut butter will enhance the flavor without compromising the cookie structure.
What’s the best way to store the cookies?
Very! To keep your peanut butter shortbread cookies fresh, store them in an airtight container at room temperature for up to one week. If you prefer a firmer texture, you can also refrigerate them in a sealed container for up to two weeks. Just remember to allow them to come back to room temperature before enjoying!
Can I freeze these cookies?
Certainly! To freeze your peanut butter shortbread cookies, first allow them to cool completely. Then, arrange the slices in a single layer on a parchment-lined baking sheet and place them in the freezer until firm, about 1-2 hours. Once frozen, transfer the cookies to a zip-top freezer bag or an airtight container, layering parchment paper between them to avoid sticking. They can last for up to 3 months—just thaw them at room temperature when you’re ready to indulge!
What if my cookies turn out dry?
Ah, no worries! If your peanut butter shortbread cookies turn out dry, it could be due to overmixing the dough or an incorrect measurement of flour. To prevent this in the future, mix the ingredients just until they come together and avoid packing the flour too tightly when measuring. Remember, a tender crumb is what makes these cookies shine!
Can I make these cookies suitable for dietary restrictions?
Absolutely! To accommodate different dietary needs, you can substitute the unsalted butter with vegan butter for a dairy-free option. You can also use gluten-free all-purpose flour in place of regular flour to make the recipe gluten-free.
