The Biggest Cookie Ever! 🍪 Cookie Monster's Magical Baking Adventure for Kids 🤩🎉

What you need

All-purpose flour, rolled oats, packed brown sugar, granulated sugar, baking soda, salt, unsalted butter softened, creamy peanut butter, large egg, vanilla extract, chocolate chips, m&ms or colorful candies, candy eyes or small candies, measuring cups and spoons, mixing bowl, mixing tool (wooden spoon or electric mixer), baking sheet, parchment paper, spatula, oven mitts, cooling rack, adult supervision required

Step 1

Wash your hands with soap and water until they are clean and dry.

Step 2

Preheat the oven to 350°F (175°C).

Step 3

Line a baking sheet with a sheet of parchment paper.

Step 4

Measure all ingredients into small bowls using these amounts: 1 cup all-purpose flour; 1 cup rolled oats; 1 teaspoon baking soda; 1/4 teaspoon salt; 1/2 cup unsalted butter softened; 1/2 cup creamy peanut butter; 1 cup packed brown sugar; 1/2 cup granulated sugar; 1 large egg; 1 teaspoon vanilla; 1 cup chocolate chips; 3/4 cup M&Ms.

Step 5

Put the butter peanut butter and both sugars into a mixing bowl.

Step 6

Beat or stir that mixture until it is smooth and creamy.

Step 7

Stir the egg and vanilla into the creamy mixture until they are fully mixed in.

Step 8

Add the measured flour oats baking soda and salt to the wet mixture and combine until a cookie dough forms.

Step 9

Fold the chocolate chips and M&Ms into the dough until they are spread evenly.

Step 10

Shape the dough on the lined baking sheet into one big round about 10 inches across and 1 inch thick.

Step 11

Chill the shaped cookie on the baking sheet in the refrigerator for 15 minutes.

Step 12

Take the baking sheet out of the oven using oven mitts when the cookie is baked for 18 to 22 minutes and the edges look golden.

Step 13

Slide the cookie onto a cooling rack to cool for about 20 minutes.

Step 14

Press candy eyes chocolate chips and extra candies into the top to decorate your giant cookie into a silly monster face.

Step 15

Share a photo and story of your finished giant monster cookie on DIY.org.

Help!?

What can I use instead of creamy peanut butter or M&Ms if I have allergies or can't find them?

Replace the 1/2 cup creamy peanut butter in the step where you add butter and peanut butter with an equal amount of sunflower seed butter for a peanut allergy, and swap the 3/4 cup M&Ms for an equal amount of extra chocolate chips or allergy-safe candy when you fold them into the dough and decorate.

My giant cookie spread too thin or didn't hold a 1-inch thickness—what should I try?

If the shaped dough won't stay about 1 inch thick, chill the shaped cookie on the lined baking sheet for longer than the 15 minutes called for and confirm the oven is fully preheated to 350°F before baking so it sets quickly during the 18–22 minute bake.

How can I adapt the activity for different ages or skill levels?

For younger kids let them wash hands, measure dry ingredients like oats and stir the wet mixture while an adult handles the oven mitts and baking, and for older kids let them shape the 10-inch round, press in chocolate chips and M&Ms, chill, bake for 18–22 minutes, cool, and decorate the monster face independently.

How can we extend or personalize our giant monster cookie after baking?

After cooling on the rack, press candy eyes, extra candies, or piped frosting into the top to create different monster faces, try swapping in mix-ins like chopped nuts or sprinkles when folding in the chocolate chips and M&Ms, and then share a photo and story of your finished monster cookie on DIY.org.

Facts about baking for kids

🍪 Cookies likely originated in Persia in the 7th century when cooks started testing small amounts of cake batter in ovens.

📏 A “pinch” is roughly 1/16 of a teaspoon—small measuring differences can change how a cookie turns out!

🔥 Most cookie recipes expect a preheated oven around 350°F (about 175–180°C) so cookies bake evenly from the start.

🧪 Baking soda needs an acidic ingredient to activate, while baking powder already contains an acid and a base.

⏱️ Giant or very thick cookies often bake better at a slightly lower temperature for longer so the center cooks without the edges burning.

How do I bake a giant monster cookie with my child?

Start by choosing a simple cookie recipe and preheat the oven. Measure dry and wet ingredients together, letting your child pour and stir. Form one large dough mound on a parchment-lined baking sheet, gently flattening it to even thickness. Bake until the edges are golden and the center is set (thicker cookies need longer). Let it cool, then decorate with icing, candies, and edible eyes to create monster features. Supervise all oven steps.

What materials and ingredients do I need to bake a giant monster cookie?

You’ll need basic ingredients: flour, sugar, brown sugar, butter, egg (or substitute), baking soda, salt, and vanilla. Optional mix-ins: chocolate chips, candies, or nuts. Tools: mixing bowls, measuring cups and spoons, spatula, baking sheet, parchment paper, cooling rack, oven mitts, and a large spoon or hands to shape the cookie. For decorating, have icing, food-safe markers, candy eyes, sprinkles, and piping bags or squeeze bottles.

What ages is baking a giant monster cookie suitable for?

Baking is great for many ages: toddlers (2–4) can pour pre-measured ingredients and mix with help; preschoolers (4–6) can measure with guidance and press decorations; school-age kids (7–10) can follow steps more independently and help with shaping; older kids (11+) can manage oven tasks with supervision. Always supervise knife use, hot surfaces, and raw-egg handling. Adjust tasks to each child’s fine motor skills and attention span.

What safety tips should I follow when baking and decorating a giant monster cookie?

Wash hands and tie back hair before starting. Avoid tasting raw dough because of raw egg and flour risks. Use child-safe utensils and keep young children away from hot pans and the oven; only adults should handle placing or removing trays. Use oven mitts, a stable step stool, and keep a clear counter space. Check for food allergies in advance and store leftovers in an airtight container after the cookie fully cools.
