How to Make Flourless Monster Cookies

Making flourless monster cookies is an easy and enjoyable process. Follow these steps carefully to ensure your cookies turn out delicious every time.

Step 1: Prepare the Dry Ingredients

In a medium bowl, start by whisking together the oats, baking soda, and salt. This step will combine all the dry ingredients nicely. Make sure that there are no clumps. Once combined, set this bowl aside for now. This helps in keeping everything organized, making it easier to mix later.

Step 2: Combine the Wet Ingredients

In a large bowl, take the melted butter and add in the brown sugar. Use a whisk to mix these two ingredients together until they are combined smoothly. Next, add the eggs to the bowl, making sure they are at room temperature. Continue whisking to incorporate the eggs fully. Finally, add the vanilla extract and creamy peanut butter to the bowl and whisk until everything is well mixed.

Step 3: Mix Dry and Wet Ingredients Together

Now that you have your dry and wet mixtures prepared, it’s time to combine them. Pour the dry oat mixture into the bowl with the wet ingredients. Using a silicone spatula, mix them together until everything is well incorporated. At this point, don’t be surprised if the dough feels sticky and gooey; that’s totally fine! This is the perfect consistency for a chewy cookie.

Step 4: Add the Fun Ingredients

Take a moment to fold in the M&Ms and chocolate chips. Be gentle while doing this to ensure that the candies stay intact and distribute evenly throughout the dough. Once everything is mixed, it’s time to chill the dough. Cover it tightly with plastic wrap and place it in the refrigerator. Let it chill for at least 30 minutes; this helps the flavors meld and makes the dough easier to scoop.

Step 5: Prepare the Oven and Baking Sheets

When you’re ready to bake, preheat your oven to 350°F (177°C). While the oven heats up, line large baking sheets with parchment paper or silicone baking mats. These will prevent the cookies from sticking and help them bake evenly.

Step 6: Scoop and Bake the Cookies

Using a cookie scoop or a heaping tablespoon, scoop out the dough and place mounds about 3 inches apart on the prepared baking sheets. This space is important to let the cookies spread as they bake. Bake the cookies in the preheated oven until the edges are set and golden brown. This usually takes about 12–15 minutes. Keep an eye on them to prevent over-baking.

Step 7: Cool the Cookies

Once they are ready, remove the trays from the oven and allow the cookies to cool on the baking sheet for about 10 minutes. This cooling time allows them to firm up a bit. After that, transfer the cookies to a wire rack to cool completely. Watching them cool adds to the excitement as you await the tasty results!

After you’ve enjoyed your cookies, you might have some leftovers. Don’t worry, they are easy to store! Proper storage can keep them fresh for longer.

Proper Storage Methods

To keep your cookies fresh, store them in an airtight container at room temperature. Take care to separate layers with parchment paper if you are stacking them. This will help prevent them from sticking together. Stored this way, your cookies will stay delicious for up to one week.

Tips for Reheating or Freezing

If you want to enjoy warm cookies later, you can reheat them in the microwave for about 10-15 seconds. Alternatively, if you want to save some for a later date, consider freezing them. Simply place the cooled cookies in a freezer-safe bag, separating layers with parchment paper, and freeze. When you want one, thaw it at room temperature or heat it directly from frozen.

Tips to Make Flourless Monster Cookies

While this recipe is straightforward, there are some common mistakes to avoid. Knowing these will help you create the best possible cookies.

Common Mistakes to Avoid

One common mistake is not measuring ingredients accurately. Make sure to use proper measuring cups and spoons for both dry and wet ingredients. This will ensure that your cookies have the right texture. Another mistake is skipping the chilling step. Chilling the dough helps the cookies maintain their shape and enhances the flavors.

Helpful Tips for Better Results

To get an even better cookie, consider using fresh ingredients. This includes fresh eggs and high-quality peanut butter. If your peanut butter is too thick, it can make the dough dry, so always stir it well before using it. Lastly, don’t be afraid to get creative with mix-ins. Adding nuts, coconut, or different types of chocolate can add variety to your cookies.

Variation of Flourless Monster Cookies

If you want to switch things up, there are many variations you can try with flourless monster cookies. Here are some fun ideas to explore.

You can also add a teaspoon of cinnamon or a tablespoon of cocoa powder for a chocolate version. If you enjoy a fruity flavor, consider adding some dried cranberries or raisins to the mix.

Adjustments for Dietary Preferences

For those looking for low-sugar options, you can substitute brown sugar with a sugar alternative that measures cup-for-cup. There are even peanut butter alternatives made from seeds for those who can’t consume nuts. Adjusting the recipe to fit your dietary needs doesn’t have to compromise flavor!

FAQs

When trying out a new recipe, many questions may come to mind. Here are answers to some frequently asked questions about flourless monster cookies.

What Can I Do if the Dish Isn’t Turning Out Right?

If your cookies spread too much or are too flat, check your oven temperature. It may be too hot, which can cause spreading.

Absolutely! You can prepare the dough and refrigerate it for up to three days. Just keep it covered tightly to prevent it from drying out. This is a great way to make cookies in advance for a gathering or special event.

What Can I Substitute for Ingredients?

If you wish to substitute ingredients, you have plenty of options! For example, almond butter can replace peanut butter for a different flavor. You can also swap out M&Ms for other candies or chips, like butterscotch or white chocolate, to change the taste.
