Step‑by‑Step Instructions for Peanut Butter Shortbread
Step 1: Preheat the Oven
Begin by preheating your oven to 325°F (163°C). While the oven heats, line an 8-inch round cake pan with parchment paper, ensuring it covers the bottom and sides. This will help your Peanut Butter Shortbread cookies release easily once baked. Set the pan aside while you prepare the cookie dough.
Step 2: Mix the Dry Ingredients
In a small bowl, whisk together 1 cup of all-purpose flour, 2 tablespoons of cornstarch, and a pinch of salt until well combined. This dry mixture is essential for achieving the buttery, crumbly texture of the Peanut Butter Shortbread. Once mixed, set it aside so you can focus on the wet ingredients next.
Step 3: Cream the Wet Ingredients
In a mixing bowl, beat together 1/2 cup of softened unsalted butter, 1/2 cup of creamy peanut butter, 1/3 cup of light brown sugar, and 1 teaspoon of vanilla extract on medium speed until the mixture is smooth and creamy. This step incorporates air into the dough, ensuring your cookies are light and flavorful. Take your time to achieve a lovely creamy consistency.
Step 4: Combine Wet and Dry Mixtures
Gradually add the dry mixture to the wet ingredients, increasing the mixer speed to high. Mix until the dough begins to clump together, which should take about 1 to 2 minutes. Be mindful not to overmix; you want just enough incorporation to enjoy the rich flavor of the Peanut Butter Shortbread cookies without losing tenderness.
Step 5: Shape the Dough
Once combined, transfer the dough into the prepared pan, pressing it evenly across the bottom with your hands or a spatula. This creates a solid base for your shortbread cookies. To ensure a well-baked treat, dock the surface with a fork by making several small holes, allowing steam to escape as it bakes.
Step 6: Add Sugar and Bake
Sprinkle a tablespoon of granulated sugar evenly over the top of the dough, enhancing both sweetness and texture. Place the pan in your preheated oven and bake for 28 to 30 minutes or until the edges are lightly browned and the center looks firm. Keep an eye on them to prevent overbaking; they should have a slight golden hue.
Step 7: Cool and Slice the Cookies
After baking, remove the Peanut Butter Shortbread from the oven and allow it to cool in the pan for about 10 to 15 minutes. This is crucial for the cookies to set properly. Using a sharp knife, carefully cut them into slices while still warm. Enjoy the warm, buttery goodness as they start to cool completely.

Peanut Butter Shortbread Cookies Recipe FAQs
What should I look for when selecting peanut butter?
Absolutely! For the best results, opt for creamy peanut butter that incorporates oil and sugar for a smooth consistency. Natural peanut butters can be grainy and may not yield the desired texture for these cookies. If you prefer a bit of crunch, crunchy peanut butter works wonderfully and adds delightful texture.
How should I store Peanut Butter Shortbread Cookies after baking?
To keep your cookies fresh, store them in an airtight container at room temperature for up to 1 week. If you want to retain that lovely crumbly texture, avoid refrigerating unless you prefer them chilled. For longer preservation, freeze your cookies in a freezer-safe bag or container for up to 3 months. Just thaw at room temperature before indulging!
Can I freeze Peanut Butter Shortbread Cookies?
Yes! Freezing these cookies is a great way to enjoy them later. Make sure to let them cool completely before freezing. Lay them in a single layer on a baking sheet and flash freeze for about an hour. Then, transfer them to a freezer-safe bag or container, stacking carefully. They can be frozen for up to 3 months. To enjoy, simply thaw at room temperature.
What if my dough is too crumbly?
Very! If you find the dough too crumbly and it won’t hold together, you can add a teaspoon of milk or water to bring it together. Start with a small amount and mix gently until the dough is cohesive. Avoid overmixing, as it can lead to a tough texture. The right balance will result in those perfectly buttery Peanut Butter Shortbread Cookies!
Are there any dietary considerations for these cookies?
Certainly! This recipe contains gluten due to the all-purpose flour and is not suitable for those with gluten allergies. To make them gluten-free, simply substitute with a gluten-free all-purpose blend. Additionally, check your peanut butter brand for any potential allergens, and consider using allergy-friendly variations if sharing with friends or family who may have allergies.
How long does it take for the cookies to cool before cutting?
I recommend letting your Peanut Butter Shortbread Cookies cool in the pan for about 10 to 15 minutes. This resting time helps them set and maintain their shape when you slice them. Just be careful not to let them cool in the pan for too long, as they can become difficult to remove! Enjoy that warm, buttery goodness while it’s fresh!
