These peanut butter cookies are incredibly simple to make and require only three ingredients. Perfect for a quick treat or a last-minute dessert, they are both delicious and satisfying. The combination of peanut butter, sugar, and a flaxseed meal mixture creates a delightful cookie that is both chewy and flavorful.

How to Store or Freeze These Cookies
To keep your peanut butter cookies fresh and delicious, store them in an airtight container at room temperature. They will stay good for up to a week.
If you prefer a longer shelf life, you can refrigerate the cookies. Place them in an airtight container or a resealable plastic bag. They will remain fresh for up to two weeks.
For those who love to plan ahead, freezing is an excellent option. First, let the cookies cool completely on a wire rack. Then, arrange them in a single layer on a baking sheet and freeze until solid. This prevents them from sticking together.
Once the cookies are frozen, transfer them to a freezer-safe container or a resealable plastic bag. Be sure to label the container with the date. Your peanut butter cookies will stay fresh for up to three months.
When you're ready to enjoy your frozen cookies, simply take out the desired amount and let them thaw at room temperature for about 15-20 minutes. For a warm treat, you can also reheat them in a preheated oven at 350°F (175°C) for 5-7 minutes.
If you want to freeze the dough instead of the baked cookies, roll the dough into 1-inch balls and place them on a baking sheet. Freeze until solid, then transfer to a freezer-safe container or resealable plastic bag. Label with the date. When you're ready to bake, there's no need to thaw the dough. Just place the frozen dough balls on a baking sheet, flatten with a fork, and bake at 350°F (175°C) for 12-14 minutes.
For an extra touch of indulgence, consider adding a sprinkle of sea salt or a drizzle of melted dark chocolate before serving. This can elevate your dessert to a whole new level of deliciousness.
How to Reheat Leftovers
Preheat your oven to 300°F (150°C). Place the peanut butter cookies on a baking sheet and cover them loosely with aluminum foil to prevent over-browning. Heat for about 5-10 minutes until they are warm and slightly crispy.
Use a microwave for a quick reheat. Place a damp paper towel over the cookies to keep them from drying out. Microwave on medium power for 10-15 seconds. Check and repeat if necessary, but be careful not to overheat as they can become too soft.
For a toaster oven, set it to 300°F (150°C). Place the cookies on a tray and heat for about 5 minutes. This method helps maintain their crisp edges while warming them through.
If you prefer a softer texture, wrap the cookies in a damp paper towel and place them in a steamer basket over boiling water for about 1-2 minutes. This method adds a bit of moisture back into the cookies.
For a stovetop method, use a non-stick skillet over low heat. Place the cookies in the skillet and cover with a lid. Heat for about 2-3 minutes, flipping halfway through to ensure even warming.
