Step‑by‑Step Instructions for Peanut Butter Cornflake Cookies

Step 1: Melt the Base Ingredients
In a large pot over medium-low heat, combine ½ cup of salted butter with 1 cup of smooth peanut butter. Stir gently until both ingredients are fully melted and creamy, which should take about 3-5 minutes. Watch for bubbling, as you want a smooth blend without caramelization. Remove from heat once fully melted for the best texture in your Peanut Butter Cornflake Cookies.

Step 2: Incorporate the Marshmallows
Add 10 oz of mini marshmallows to the melted peanut butter mixture, stirring constantly for about 2-3 minutes. Continue heating gently until the marshmallows are completely melted and the mixture is glossy. Be sure to achieve a uniform blend without any lumps, as this will ensure your cookies have that delightful chewiness.

Step 3: Combine with Cornflakes
Once the mixture is smooth, fold in 7 cups of cornflakes, ensuring each flake is evenly coated. Use a spatula to mix gently but thoroughly, as you want to preserve the crunchiness of the cornflakes for your Peanut Butter Cornflake Cookies. If desired, add an additional 1 oz of mini marshmallows and ⅓ cup of optional peanut butter chips for extra flavor.

Step 4: Form the Cookies
Prepare a parchment-lined baking sheet and use a greased cookie scoop to drop about 10 balls of the mixture onto the sheet. Gently flatten each ball to about 1 inch thick without overly packing them; this will help them hold their shape as they set. Place the baking sheet in a cool area for the cookies to begin setting.

Step 5: Drizzle for Finish
In a microwave-safe bowl, melt 2 tbsp of peanut butter chips along with ½ tsp of vegetable or canola oil in 30-second increments, stirring in between until smooth. Transfer the melted mixture to a ziplock bag, snip a small corner, and drizzle it over the cooled Peanut Butter Cornflake Cookies for an attractive finish.

Step 6: Allow to Set
Let your cookies set at room temperature for 20-30 minutes until they firm up slightly. This time will allow the marshmallow mixture to solidify into the chewy, delightful texture you love. Once set, serve your delicious Peanut Butter Cornflake Cookies immediately or store in an airtight container at room temperature.

How to Store and Freeze Peanut Butter Cornflake Cookies

Room Temperature: Store your cookies in an airtight container at room temperature for up to 2 days to maintain their chewy texture and crunchy cornflakes.

Refrigeration: Avoid refrigerating the cookies as it can make them hard and change their delightful texture.

Freezing: If you need to store them longer, consider freezing—place in a single layer in a freezer-safe container, separating layers with parchment paper, for up to 1 month.

Reheating: To restore gooeyness, microwave thawed cookies for about 5 seconds before enjoying your Peanut Butter Cornflake Cookies again.

Peanut Butter Cornflake Cookies Recipe FAQs

How do I select the right ripeness of ingredients for this recipe?
Absolutely! When it comes to the peanut butter, using a smooth variety ensures that the cookies have a creamy texture. For marshmallows, look for fresh ones without any hard spots. Fresh marshmallows will melt beautifully and add that gooey chewiness we all adore.

What is the best storage method for Peanut Butter Cornflake Cookies?
You’ll want to store your cookies in an airtight container at room temperature for up to 2 days. This method helps maintain their chewy texture and the crunch of the cornflakes. Avoid refrigerating as it can alter their delightful consistency.

Can I freeze my Peanut Butter Cornflake Cookies?
Yes, indeed! To freeze, place your cookies in a single layer in a freezer-safe container, separating each layer with parchment paper. This method will help prevent them from sticking together. They can be frozen for up to 3 months. When you’re ready to enjoy them again, simply thaw at room temperature or microwave for about 5 seconds for that gooey goodness.

What should I do if my cookie mixture is too sticky?
Very much! If you find your mixture sticks too much, try to gently fold in a few extra cornflakes to absorb the moisture. Remember to mix just enough to maintain the cookie’s integrity without squishing the cornflakes too much. If the mixture feels overly soft, it may be helpful to place it in the refrigerator for about 10-15 minutes to firm it up before forming the cookies.

Can I substitute any ingredients in the Peanut Butter Cornflake Cookies?
Absolutely! If you’re looking for alternatives, you can substitute the cornflakes with Golden Graham cereal for a sweeter flavor or use chocolate chips instead of peanut butter chips for a chocolatey twist. If you have nut allergies, consider using sunflower seed butter for a nut-free option, which will still provide a similar creamy texture.

Are these cookies safe for pets or those with allergies?
Very! It’s important to note that these cookies are not intended for pets, as ingredients like chocolate (if used) and peanut butter can be harmful to certain animals. If serving to someone with allergies, ensure they are aware of peanut contents, and consider using alternatives like sunbutter to avoid nut allergies.
