Step-by-Step Guide – How to Make Thick and Chewy Monster Cookies
Mixing and Preparing the Cookie Dough
- Cream the Butter and Sugars: Beat softened butter with brown and granulated sugars on medium speed for 2–3 minutes until pale and fluffy. This aeration helps create that signature chewy texture.
- Mix in the Peanut Butter and Eggs: Blend in creamy peanut butter, then add eggs one at a time, mixing well. Stir in vanilla extract until smooth and fragrant—the heart of great M&M cookies recipes.
- Combine the Dry Ingredients: Whisk flour, baking soda, salt, and oats together. Using old-fashioned oats ensures that hearty, chewy cookie texture.
- Bring It All Together: Gradually fold dry ingredients into the wet until just combined. Avoid overmixing for a thick, sticky dough.
- Fold in the Mix-Ins: Add chocolate chips and M&Ms, gently stirring with a spatula. Reserve a few candies for pressing on top before baking if desired.
- Chill the Dough: Refrigerate for about 30 minutes. Chilling helps the butter firm up and yields thicker, richer cookies.
By the end of this cookie dough preparation stage, your dough should be dense yet scoopable—perfect for holding its shape and baking into cookies that are chewy inside and lightly crisp around the edges.
Baking and Cooling for the Perfect Texture
- Preheat the Oven: Heat to 350°F (175°C) and line baking sheets with parchment or silicone mats for even baking.
- Shape the Cookies: Scoop 1½-tablespoon portions, spacing them 2 inches apart to prevent merging.
- Bake Until Just Set: Bake for 10–12 minutes until edges are golden and centers slightly underbaked. Remove early for that ideal chewy cookie texture.
- Cool Properly: Rest cookies on the sheet for 5 minutes, then transfer to a wire rack to finish setting.
- Troubleshooting Tips: Too flat? Chill longer or reduce butter softness. Too dry? Recheck flour amounts. Underbaked? Return to oven briefly—remember, softness equals success in Monster Cookie Recipes.
When cooled, your cookies should be thick, tender, and studded with colorful chocolates. With these chewy cookie tips, every batch of Thick and Chewy Monster Cookies will taste like home-baked perfection.
