Grandma’s Secrets for the Best Peanut Cookies
To ensure your cookies turn out perfectly golden and crisp, keep these simple tips in mind:
- The Peanut Texture: When grinding the roasted peanuts in the food processor, pulse carefully. You want a coarse, sandy flour with tiny bits of peanut for crunch. Avoid over-processing, or the peanuts will release their natural oils and turn into peanut butter!
- Skin On or Off? You can use peanuts with or without the skin. Leaving the skin on gives the cookies a beautiful, rustic speckled look and a deeper flavor. Removing the skin results in a lighter, more delicate cookie.
- The Fork Trick: Pressing the dough balls gently with a fork not only flattens them so they bake evenly, but it also creates classic ridges that catch the heat and make the edges extra crispy.

Ingredients
Method
- Place the roasted peanuts in a food processor and pulse until they are finely ground into a coarse, sandy flour. Be careful not to over-process into paste.
- Transfer the ground peanuts to a large mixing bowl. Add the eggs, sugar, and all-purpose flour.
- Mix the ingredients thoroughly using your hands until the ingredients bind together and the dough becomes smooth and homogeneous.
- Scoop out small portions of the dough (about 40g each) and roll them firmly into smooth balls between your palms.
- Place the dough balls onto a greased or floured baking tray, leaving a little space between them.
- Using the back of a fork, gently press down on each cookie ball to flatten it slightly and create a decorative criss-cross or lined pattern.
- Bake in a preheated oven at 180°C (350°F) for about 15 minutes, or until the bottoms and edges are lightly golden.

Notes
- Storage: These cookies keep exceptionally well! Once completely cooled, store them in an airtight glass jar or container at room temperature for up to 7 days. They will stay nice and crunchy.
- Gluten-Free Option: You can easily make this recipe gluten-free by replacing the 1/2 cup of all-purpose flour with rice flour or cornstarch (amido de milho), which gives them an even softer, melt-in-your-mouth texture.
