Ingredients

• ½ cup unsalted butter at room temperature
• ½ cup light brown sugar, lightly packed
• ¼ cup granulated sugar
• 1 large egg at room temperature
• ⅔ cup creamy peanut butter (not natural-style)
• 1 teaspoon pure vanilla extract
• 1 ¼ cups all-purpose flour
• ½ teaspoon baking soda
• ½ cup old-fashioned whole rolled oats
• ½ cup M&Ms
• ½ cup semi-sweet chocolate chips (optional)

How To Make Soft Monster Cookies

Step 1: Prepare Your Ingredients

Start by measuring all your ingredients accurately. Make sure your butter and egg are at room temperature for the best creaming and mixing results. Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper or a silicone baking mat.

Step 2: Cream Butter and Sugars

In a large mixing bowl, use a hand mixer or stand mixer fitted with the paddle attachment to cream together the unsalted butter, light brown sugar, and granulated sugar. Beat on medium speed for about 2-3 minutes until the mixture is light, fluffy, and pale in color.

Step 3: Add Egg, Peanut Butter, and Vanilla

Add the egg, creamy peanut butter, and pure vanilla extract to the creamed butter and sugar mixture. Continue beating on medium speed until everything is well combined and smooth.

Step 4: Mix Dry Ingredients

In a separate bowl, whisk together the all-purpose flour and baking soda. This ensures the baking soda is evenly distributed throughout the dough.

Step 5: Combine Dry and Wet Ingredients

Gradually add the flour mixture to the wet ingredients, mixing on low speed just until combined. Avoid overmixing to keep the cookies tender.

Step 6: Fold In Oats, M&Ms, and Chocolate Chips

Using a spatula, fold in the old-fashioned oats, M&Ms, and the optional semi-sweet chocolate chips. These add texture and bursts of color and flavor.

Step 7: Scoop the Dough

Use a cookie scoop or spoon to portion out the dough onto your prepared baking sheet. Leave about 2 inches between each cookie to allow for spreading.

Step 8: Bake

Bake the cookies at 350°F (175°C) for 10-12 minutes. The cookies should be set around the edges but still soft in the middle. They will firm up as they cool.

Step 9: Cool and Enjoy

Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. Serve and enjoy the soft, chewy goodness!

Expert Tips

• For the softest cookies, don’t overbake. Pull them out when the edges are set but the centers still look slightly undercooked.
• Using creamy peanut butter instead of natural-style helps the dough hold together better and gives a smoother texture.
• If you want your cookies extra thick, chill the dough for 30 minutes before baking.
• Room temperature ingredients blend more easily, creating a uniform dough that bakes evenly.
• To keep your cookies fresh, store them in an airtight container at room temperature.

Variations and Customizations

• Nut-Free Option: Substitute the peanut butter with sunflower seed butter for those with nut allergies.
• Mix-In Swap: Try adding chopped nuts, such as walnuts or pecans, instead of chocolate chips.
• Flavor Boost: Add a pinch of cinnamon or a teaspoon of instant espresso powder to enhance the flavor profile.
• Gluten-Free: Substitute all-purpose flour with a gluten-free baking blend to accommodate dietary needs.
• Vegan Version: Use a flax egg (1 tbsp ground flaxseed + 3 tbsp water) and dairy-free butter to make these cookies vegan-friendly.

How to Store Leftovers

To keep your Soft Monster Cookies fresh and chewy, store them in an airtight container at room temperature for up to 5 days. If you want to store them longer, place the cookies in a sealed container or zip-top bag and freeze for up to 3 months. When ready to enjoy, simply thaw at room temperature or warm in the microwave for 10-15 seconds to refresh their soft texture.

FAQ

Can I use natural peanut butter in this recipe?

Natural peanut butter can be used, but because it contains less stabilizers and oil separation occurs, the dough might be a bit more crumbly. For best results, use creamy peanut butter that is not natural-style.

Are old-fashioned oats necessary?

Old-fashioned rolled oats add a chewy texture to the cookies. If you only have quick oats, you can use those, but the texture will be slightly different—less chewy and more soft.

Can I omit the chocolate chips?

Absolutely! The chocolate chips are optional and can be left out if you prefer. The cookies will still be delicious with just the M&Ms and oats.

How do I prevent cookies from spreading too much?

Make sure your dough is chilled before baking if you want thicker cookies. Also, avoid using too much butter or overmixing the dough, as that can cause excessive spreading.
