Tips & Variations

- If you prefer a crunchier cookie, bake for an additional 1-2 minutes, watching carefully to avoid burning.
Storage
Store the cookie in an airtight container at room temperature for up to 2 days. For longer storage, wrap tightly and freeze for up to 1 month. Reheat gently in a microwave for 10-15 seconds to enjoy a warm, freshly baked feel.

Serve this delicious recipe with your favorite sides.
FAQs
Can I use whole egg instead of just the yolk?
Using a whole egg will make the cookie slightly cakier and less rich. This recipe calls for yolk to keep it chewy and dense, but you can experiment if you prefer a softer texture.
Is it possible to make this cookie gluten-free?
Yes, substitute the all-purpose flour with a gluten-free flour blend measured cup-for-cup. Make sure your baking powder and other ingredients are gluten-free as well.

Notes
- This recipe makes a single large cookie, perfect for a solo treat or for testing the recipe before scaling up.
- Flattening the dough to about 1 inch thickness helps achieve the ideal balance of a slightly crispy edge and a chewy center.
- The cookie continues to bake slightly as it cools, so avoid baking until fully firm to maintain softness.
- Use natural peanut butter for a less sweet, more pronounced peanut flavor.
- Storing leftover dough in the fridge allows you to make fresh cookies anytime in small batches.
