Ingredients for Best Monster Cookies
- 1 cup unsalted butter, softened
- 1 cup brown sugar, packed
- 1 cup granulated sugar
- 1 cup creamy peanut butter
- 3 large eggs
- 1 teaspoon vanilla extract
- 4 cups rolled oats
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 2 cups chocolate chips
- 1 cup M&M’s candies
Ingredient Notes and Substitutions
- Unsalted butter: Adds richness and flavor; use salted butter if needed, but reduce added salt.
- Brown sugar: Provides moisture and a richer flavor; light brown sugar works well if dark is unavailable.
- Creamy peanut butter: Essential for that classic taste; chunky peanut butter can be used for added texture.
- Rolled oats: Gives chewiness; quick oats can be used but may alter texture slightly.
How to Make Best Monster Cookies
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This ensures even baking, creating that perfect cookie texture.
Step 2: Cream the Butter and Sugars
In a mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy. This step incorporates air, which contributes to the cookie’s texture.
Step 3: Add Peanut Butter and Eggs
Mix in the peanut butter, eggs, and vanilla extract until well combined. The peanut butter adds richness and flavor to the cookies.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the rolled oats, flour, baking soda, and salt. This helps distribute the dry ingredients evenly throughout the dough.
Step 5: Mix Dry and Wet Ingredients
Gradually add the dry mixture to the wet mixture, stirring until just combined. Overmixing can lead to dense cookies, so be gentle.
Step 6: Fold in the Chocolate and M&M’s
Gently fold in the chocolate chips and M&M’s until evenly distributed. This colorful addition makes every cookie a delightful surprise.
Step 7: Scoop the Dough
Using a cookie scoop or tablespoon, drop dough onto lined baking sheets. Leave space between each ball to allow for spreading during baking.
Step 8: Bake the Cookies
Bake for 10-12 minutes or until the edges are golden brown. Let them cool on the baking sheet for a few minutes before transferring to a cooling rack.
Pro Tip: For extra chewiness, slightly underbake the cookies and let them finish cooking on the baking sheet.
Tips for the Best Best Monster Cookies
- Use room temperature ingredients for better mixing.
- Don’t skip the chilling step if you have time; it helps the cookies hold their shape.
- Experiment with different mix-ins like nuts or dried fruit for a unique twist.
- Store leftover cookies in an airtight container to maintain freshness.
- For a fun presentation, sprinkle a few extra M&M’s on top before baking.
Common Mistakes to Avoid
- Overmixing the dough can lead to tough cookies. Mix just until combined for the best texture.
- Not using enough flour can make cookies too flat. Measure flour correctly for best results.
- Baking on an ungreased or unlined sheet can cause sticking. Always use parchment paper for easy removal.
- Skipping the cooling time can result in too soft cookies. Allow them to cool slightly to set properly.
Serving Suggestions
These cookies are fantastic on their own or paired with a glass of milk. For a treat, serve them warm with a scoop of vanilla ice cream.
- Classic milk
- Hot chocolate
- Coffee
- Ice cream sandwiches
- Fruit salad for a fresh contrast
Variations to Try
- Substitute half of the chocolate chips with white chocolate for a different flavor profile.
- Add chopped nuts for extra crunch and flavor.
- Incorporate dried cranberries or raisins for a fruity twist.
- Use different flavored chips like butterscotch or mint for a seasonal flair.
Dietary Adaptations
- Gluten-free: Substitute flour with a gluten-free blend.
- Dairy-free: Use vegan butter and dairy-free chocolate chips.
- Vegan: Replace eggs with flax eggs and use plant-based butter.
- Low-carb/keto: Use almond flour and sugar substitutes to reduce carbs.
Storage and Reheating
Refrigerator
Store cookies in an airtight container in the fridge for up to a week.
- Keep layers separated with parchment paper to avoid sticking.
