Reheating cookies is a great way to restore their crisp texture and fresh flavor if they have gotten stale sitting out or being stored. With the right technique, you can make day-old cookies taste like they just came straight out of the oven. This guide will provide tips and instructions for reheating cookies using a microwave, oven, air fryer, and toaster oven.
Reheating Cookies in the Microwave
The microwave provides a quick and easy way to reheat cookies in just minutes.
What You Need
- Leftover cookies
- Microwave-safe plate
- Paper towel
Instructions
- Place 1-6 cookies on a microwave-safe plate depending on size. Make sure they are spaced apart.
- Cover the cookies with a paper towel to prevent splattering and trapping steam.
- Microwave in 30 second intervals until the cookies are warmed through. The time will depend on your microwave wattage and amount of cookies.
- Allow the cookies to sit covered for 30 seconds after microwaving to evenly distribute the heat.
- Repeat with any remaining cookies. Avoid microwaving more than 6 cookies at once.
Tip: For best results, microwave cookies at 50% power to ensure they heat gradually without getting rubbery.
Additional Microwave Tips
- Cookies with fillings or toppings may require extra microwave time. Watch carefully to avoid overheating.
- Allow thicker cookies like brownies more time, 45 seconds to 1 minute.
- Rotate the plate if there are microwaving hotspots.
- Control crispness based on time. The longer the cookies microwave, the softer they may get.
Baking Cookies in the Oven
The oven allows you to crisp up cookies by applying dry heat.
What You Need

Additional Oven Tips

FAQ About Reheating Cookies
How do you soften hard cookies?
Place hard, dry cookies in an airtight container with a slice of bread or apple overnight. The moisture softens them. You can also microwave 10-15 seconds to soften.
Can you reheat cookie dough in the microwave?
It’s not recommended. Microwaving unbaked cookie dough can create uneven cooking and lead to raw eggs. Always bake cookie dough in the oven as directed.
Is it safe to reheat cookies with cream or custard filling?
Yes, but take care not to overheat, which can cause the filling to separate or curdle. Microwave in short 10-15 second bursts.
Can I reheat break-and-bake cookie dough?
Yes, follow package instructions for baking frozen cookie dough. Thaw first if needed and bake 8-12 minutes until set.
How long do reheated cookies last?
Reheated cookies are best consumed within 3-5 days. Store in an airtight container at room temperature. Do not refrigerate or freeze after reheating.
Easy Recipes for Stale Cookies
Give leftover cookies new life with these tasty recipes!
1. Cookie Ice Cream Sandwiches
Take softened vanilla ice cream and spread onto the flat side of a stale cookie. Top with another cookie to make a sandwich. Roll edges in sprinkles or chocolate chips before freezing.
2. Cookie Crumble Topping
Pulse stale cookies in a food processor until they become fine crumbs. Use as a crunchy topping on ice cream, yogurt, cakes and pies.
3. No-Bake Cookie Balls
Break stale cookies into pieces and pulse in a food processor until fine crumbs form. Add peanut butter or other binder and roll into balls. Coat in melted chocolate or sprinkles. Refrigerate until set.
Tips for Storing Cookies to Prevent Staling
- Store cookies at room temperature in an airtight container.
- Place cookies in layers separated by wax paper.
- Avoid refrigerating unless directed on packaging. This causes premature staling.
- Freeze cookie dough logs or pre-scooped dough rather than baked cookies. Thaw overnight before baking.
- Keep cookies away from moisture and humidity. Use a container with a tight seal.
- Baked cookies stay freshest for 2-3 days at room temperature.
- Unbaked refrigerated cookie dough lasts 1-2 weeks in the fridge.
