Red, White & Blue Kitchen Sink Cookies are the kind of cookies that disappear fast. Packed with oats, chocolate chips, crunchy cereal, and colorful candies, they have a little bit of everything. The red, white, and blue colors make them perfect for summer celebrations, but honestly, I’d make them any time of year. They’re soft, chewy, and loaded with fun textures in every bite.
These cookies are very simple to make.ย In a large mixing bowl, beat the softened butter and brown sugars until they are combined.ย Mix in the vanilla followed by the eggs and egg yolk. Make sure everything is combined well.
Add the flour, baking soda, baking powder and salt and then stir in the oats.ย Fold in the M&M’s, crushed Rice Chex and chocolate chip.
Make 1/4-cup scoops of dough and place 5-6 on a baking sheet.
Bake for 8 minutes, rotate the pan for another 2 minutes and then remove from the oven. Press additional red, white & blue M&M’s onto the top of each cookie and bake another 2 minutes.
Let the cookies cool on the baking sheet.ย Serve warm with milk or at room temp!

For the Cookies:
- 1 cup (2 sticks) salted butter, softened
- 1 cup dark brown sugar
- 1/3 cup light brown sugar
- 2 large eggs
- 1 large egg yolk
- 1 tbsp vanilla extract
- 2 cups all-purpose flour
- 2 tsp baking soda
- 2 tsp baking powder
- 1/2 tsp kosher salt
- 2 cups old-fashioned oats
- 1 & 1/4 cups red, white, and blue M&M’s, divided
- 1 cup Rice Chex cereal, lightly crushed
- 1 cup semi-sweet chocolate chips or chocolate chunks
Instructions
Make the Cookies:
Preheat the oven to 350ยฐF and line a baking sheet with parchment paper.
In a large mixing bowl, beat the butter, dark brown sugar, and light brown sugar until combined. Mix in the vanilla, then add the eggs and egg yolk one at a time, beating until incorporated.
Add the flour, baking soda, baking powder, and salt, mixing just until combined. Stir in the oats, then fold in 1 cup of the M&M’s, the crushed Rice Chex cereal, and chocolate chips.
Portion the dough into 1/4-cup balls and place them about 3 inches apart on the prepared baking sheet. Bake for 8 minutes, rotate the pan, and continue baking for 2 minutes. Remove the pan from the oven and gently press the remaining M&M’s into the tops of the cookies. Return to the oven and bake for an additional 2 to 3 minutes.
Allow the cookies to cool on the baking sheet. They will continue to set as they cool.
Chef’s Notes:
- For the most festive look, reserve some of the M&M’s for pressing into the cookies before they finish baking.
- Store cookies in an airtight container at room temperature for up to 4 days.
- The cookie dough can be portioned and frozen for up to 3 months. Bake directly from frozen, adding 1 to 2 extra minutes to the baking time.
