Ingredient Notes

Unsalted Butter (3/4 cup): Room temperature butter ensures a smooth, creamy base. Salted butter? Reduce added salt.
Light Brown Sugar (1 cup): Adds moisture and rich molasses flavor.
Granulated Sugar (1/4 cup): Balances sweetness and helps crisp the edges.
Smooth Peanut Butter (1/2 cup): Adds flavor and chew. Avoid natural peanut butter—it separates.
Egg + Egg Yolk: The yolk adds richness and helps bind everything.
Vanilla Extract (1 tsp): Rounds out flavor. Use pure vanilla for best results.
All-Purpose Flour (2 1/4 cups): Spoon and level for accuracy.
Quick Oats (3/4 cup): Adds texture without making cookies overly dense.
Baking Soda (1 tsp): Helps the cookies rise and spread just enough.
Kosher Salt (1/2 tsp): Enhances all the flavors.
Semi-Sweet Chocolate Chips (3/4–1 cup): Classic cookie flavor.
White Chocolate Chips (1/2 cup): For sweetness and visual contrast.
M&M Candies (1 cup): Use red, white, and blue for holiday flair.

Equipment Tip: A stand mixer with paddle attachment helps cream the butter and sugars efficiently.

How To Make 4th of July Monster Cookies

Preheat oven to 350°F. Line 2 baking sheets with parchment paper.
Cream the butter, sugars, and peanut butter (3 minutes on medium-high) until light and fluffy. Scrape the bowl halfway.
Add egg and egg yolk one at a time, mixing on low. Add vanilla.
In a separate bowl, whisk together flour, oats, baking soda, and salt.
Gradually add dry ingredients to the wet mix. Mix until just combined—don’t overdo it.
Fold in chocolate chips and M&Ms with a spatula for even distribution.
Scoop dough (2 tbsp or 2 oz each) onto lined pans, spacing cookies at least 2 inches apart.
Bake 9–11 minutes, or until edges are golden and centers look puffy and slightly pale.
Midway, lift and drop the cookie sheet inside the oven (optional). This flattens them for that signature chewy look.
After baking, drop tray again if needed to flatten tops. Cool on sheet for 10 mins, then transfer to wire rack.

Texture tip: Don’t overbake! You want the centers to look slightly underdone—they’ll finish as they cool.

Storage Options

Room Temperature: Store in airtight container up to 5 days.
Refrigerator: Extend shelf life to 7–8 days (but let cookies come to room temp before serving).
Freezing (Unbaked): Scoop dough, freeze on tray, then bag. Bake from frozen +2 mins.
Freezing (Baked): Freeze cooled cookies in zip-top bags for up to 2 months. Thaw at room temp.
Reheating Tip: 10 seconds in the microwave restores that fresh-baked softness.

Variations and Substitutions

No peanut butter? Use almond or sunflower butter.
Gluten-free? Substitute a 1:1 gluten-free flour blend and certified GF oats.
Make it spooky: Swap colors for Halloween M&Ms.
More crunch: Add chopped pretzels or nuts.
Mini cookies: Use a 1 tbsp scoop and bake 7–8 minutes.

Frequently Asked Questions

Can I make the dough ahead of time?
Yes! Chill up to 2 days or freeze it. Let soften slightly before scooping.

Why drop the cookie tray mid-bake?
It helps flatten the cookies and creates those bakery-style ripple textures.

Can I use natural peanut butter?
It’s not recommended. Natural peanut butter separates and changes the texture.

Why are my cookies dry?
Overbaking is usually the culprit. Also, make sure not to pack the flour.

How do I store these for a party?
Stack cooled cookies between wax paper in an airtight container.

Can I add more chocolate?
Yes! Add an extra 1/4 cup of your favorite chips or chunks.
