My go-to party dessert has quickly become this eye-catching Cookie Monster Gooey Butter Cake. Kids and grown-ups alike can't resist the bright blue, cookie-studded filling, and everyone loves that magical texture that sits right between cake and cookie – it hits all the sweet spots just right.
This treat came about when my nephew wanted Cookie Monster everything for his birthday. What began as just a themed birthday experiment turned into our family's signature sweet – now everyone battles for the final slice.
Ingredients
- Yellow cake mix: Forms a soft, cookie-like foundation that holds up the gooey goodness on top
- Cream cheese: Adds a tangy kick and helps create that signature ooey-gooey layer
- Powdered sugar: Brings the sweetness and contributes to that melt-in-your-mouth feeling
- Blue food coloring: Turns an ordinary sweet into a fun character-inspired delight
- Chocolate chip cookies: Give awesome crunchy bits throughout
- Oreos: Add bold color contrast and their unique cookie taste
- Mini chocolate chips: Scatter tiny chocolate moments in every mouthful
- Vanilla extract: Ties all flavors together with its gentle background notes
Step-by-Step Instructions
- Create the Cookie Base:
- Mix your yellow cake mix with melted butter and egg until you get a thick dough. Don't worry if it looks too dry at first – just keep mixing and it'll come together. Gently stir in the mini chocolate chips so they spread evenly through the dough. Push the mixture firmly into your pan to make a flat layer. If it's sticking to your fingers, just wet your hands slightly.
- Prepare the Gooey Layer:
- Whip the cream cheese for about 2 minutes on medium speed until it's completely smooth. Mix in the eggs and vanilla until they're fully blended. Add powdered sugar one cup at a time, mixing well after each addition. Your mixture should be totally smooth before coloring it. Slowly add blue food coloring until you get that perfect Cookie Monster shade (it'll get a bit darker when baked). Using a spatula, gently fold in the crushed cookies and mini chips so you don't mess up that pretty blue color.
- Assemble and Bake:
- Spread the gooey blue mixture evenly over your cookie base, making sure it reaches all the edges. Scatter crushed Oreos and chocolate chip cookies on top, pushing them down slightly so they stick. Bake until you see set edges but the middle still jiggles a bit when you shake the pan gently. Don't leave it in too long or you'll lose that awesome gooey texture.

This dessert holds a special place in my heart because it mixes my love for childhood flavors with fun presentation. I knew we had a winner when my usually serious father-in-law went back for multiple helpings at our family get-together.
Storage Tips
Keep these gooey treats in the fridge for the best results. Just wrap them tightly with plastic or put them in a sealed container and they'll stay good for about 5 days. They actually taste even better cold – almost like fudge! If you want to save them longer, wrap single pieces in plastic and foil, then stick them in a freezer bag. Just move them to the fridge the night before you want to eat them.
Perfect Pairings
This Cookie Monster treat works great with other sweets and drinks. Try it with a scoop of vanilla ice cream for a hot-and-cold combo, or gulp it down with a glass of cold milk for that classic cookie experience. Coffee fans will love how a hot cup cuts through the sweetness. When I host parties, I make this cake the star of a dessert spread with chocolate-dipped strawberries and extra cookies arranged around it for a fun theme.

Troubleshooting Guide
Getting that perfect gooey texture might take a try or two. If your blue layer seems too runny, cook it a bit longer in 5-minute chunks, watching for the edges to firm up. Want it less gooey? Just add another 1/4 cup of powdered sugar to the mixture. If your blue color looks washed out, try adding color in two stages – first when mixing the cream cheese, then more after you've added the powdered sugar to get that bright Cookie Monster blue.
