Ingredients You’ll Need

3/4 cup all-purpose flour: All-purpose flour gives structure and helps the cookies set while still allowing a chewy interior.
1/2 cup old fashion rolled oatmeal: Old fashion rolled oatmeal adds chew and hearty texture—key to the monster cookie character.
1/2 teaspoon baking soda: Baking soda provides a gentle lift so the cookie tops brown and the centers stay thick.
1/4 teaspoon salt: Salt balances sweetness and enhances the other flavors in the cookie.
1/2 cup unsalted butter: Unsalted butter supplies richness and helps dissolve the sugars for a glossy, fudgy interior.
3/4 cup brown sugar, lightly packed: Brown sugar adds moisture and a deeper caramel note that keeps the centers chewy.
1/2 cup granulated sugar: Granulated sugar contributes sweetness and helps the tops caramelize and brown.
1 large egg: The egg binds ingredients and adds tenderness to the cookie batter.
1 teaspoon vanilla extract: Vanilla extract lifts and rounds the overall flavor without overpowering the mix-ins.
1/2 cup mini chocolate chips: Mini chocolate chips provide melty chocolate pockets while keeping bites evenly studded.
1/2 cup mini M&Ms: Mini M&Ms add color, candy crunch, and pockets of chocolate that contrast with the cookie chew.
1/3 cup sweetened shredded coconut: Sweetened shredded coconut gives a chewy, tropical note and subtle sweetness in each bite.
1/4 cup toffee bits: Toffee bits introduce buttery, caramelized crunch and a deeper toffee flavor against the chocolate.

How to Make It

Preheat oven to 375 degrees.
In a large bowl, whisk together 3/4 cup all-purpose flour, 1/2 cup old fashion rolled oatmeal, 1/2 teaspoon baking soda, and 1/4 teaspoon salt; set aside.
Place 1/2 cup unsalted butter in a medium saucepan over medium heat and cook, stirring, until melted. Turn off the heat and stir in 3/4 cup brown sugar and 1/2 cup granulated sugar until combined.
Add 1 large egg and 1 teaspoon vanilla extract to the butter-sugar mixture and whisk to combine.
Slowly add the reserved dry ingredients to the butter-sugar mixture, whisking until combined and no flour streaks remain. Fold in 1/2 cup mini chocolate chips, 1/2 cup mini M&Ms, 1/3 cup sweetened shredded coconut, and 1/4 cup toffee bits.
Scrape and divide batter into four shallow 6-inch ramekins — avoid overfilling. Bake at 375 degrees until the tops are browned and the center is just set (the interior should remain thick and chewy).
Remove ramekins from oven and transfer to a wire rack to cool briefly before serving.

Ramekin Portioning & Bake Time

This recipe is designed to yield batter for four shallow 6-inch ramekins. Use shallow ramekins so the cookie bakes with a browned top and a thick chewy center.

Baking time varies with ramekin material (ceramic retains heat; metal bakes faster) and oven differences. Rely on visual cues rather than a fixed minute count.

Use four shallow 6-inch ramekins; avoid deeper dishes which change bake time.
Do not overfill—leave space for slight rise to prevent overflow.
Ceramic ramekins may require a few extra minutes versus metal; check for a browned top and a center that’s just set.

Mix-In Swap Ideas

Customize the monster cookie mix-ins to suit preferences or allergies. You can keep the overall ratios and simply swap flavors.

To make the cookies nut-free or change textures, pick one or two substitutions rather than swapping everything at once.

For nut-free: omit toffee bits (or replace with extra mini chocolate chips).
If you don’t like coconut: replace 1/3 cup sweetened shredded coconut with 1/3 cup chopped nuts or extra oats (if no nut allergy).
Swap mini M&Ms for an equal amount of mini chocolate chips or chopped chocolate to keep chocolate intensity.

Make-Ahead, Freeze & Reheat

You can prepare these for a party by making the batter ahead or by freezing baked ramekin cookies. For batter: cover tightly and refrigerate up to 24 hours, then bake from chilled (add a couple minutes to baking).

Baked ramekin cookies freeze well when fully cooled. Wrap each ramekin tightly in plastic wrap and foil and freeze up to 1 month; thaw in the refrigerator or at room temperature before reheating.

To freeze baked: cool completely, then wrap and freeze up to 1 month.
To reheat from thawed: place ramekin in a 350-degree oven until warm (about 10–15 minutes, depending on ramekin).
To bake batter from chilled: allow an extra 2–4 minutes of bake time; again, use a browned top and just-set center as your cue.

Tips for Success

Avoid overfilling ramekins: Fill each shallow 6-inch ramekin so there’s room for the cookie to rise slightly without overflowing—about three-quarters full is a safe target.

Watch for visual doneness: Look for a browned top and a center that’s just set (not liquid). The center will firm as it cools, preserving a chewy interior.

Mix-ins and distribution: Fold mix-ins gently so they stay evenly distributed rather than settling to the bottom.

Serve while warm: These are best warm from the oven — a short cool on a rack makes them easier to handle, and a scoop of vanilla ice cream is a great finishing touch.

Frequently Asked Questions

Yes, you can substitute quick oats, but the texture will be softer and less chewy. Old-fashioned rolled oats give the chewier, heartier bite that defines monster cookies.

No — mini M&Ms add color and candy shell crunch, but you can replace them with an equal amount of mini chocolate chips or chopped chocolate for a more chocolate-forward cookie.

Melting the butter dissolves the sugars into a cohesive mixture that produces a fudgy, dense interior rather than a light, cake-like crumb—key to the thick, chewy texture of these deep-dish cookies.

Ready to bake

These deep-dish monster cookies are an easy way to turn pantry staples into an impressive, individual dessert — perfect for Halloween, parties, or any time you want a warm, chewy treat.
