Ingredients
- 1 cup (227 g) Unsalted butter room temperature
- ¾ cup (100 g) Brown sugar
- ¾ cup (110 g) White sugar
- 2 large Egg large
- 3 cups (375 g) All-purpose flour
- 1 teaspoon Baking soda
- ¼ teaspoon Baking powder
- ½ teaspoon Salt
- 2 teaspoon Vanilla extract
- 2 cup (400 g) M&M candy Save some for the top.
Instructions
- Preheat oven to 350°F / 177°C / Gas Mark 4. Line a 9 x 9-inch square cake pan with parchment paper making sure to leave an overhang so you can pick the baked bar out easily. Pro tip - You can also use a baking dish and line it with foil.
- Dry ingredients - In a medium mixing bowl, combine flour, baking powder, baking soda, and salt – Set aside.
- Wet ingredients - In the bowl of a stand mixer, with the paddle attachment, cream butter and both white sugar and brown sugar until almost light and fluffy. Pro tip - It is important to cream until the sugar has almost dissolved. Otherwise, the cookie bars will not be soft.
- Next, add the eggs, one at a time, followed by the vanilla extract and flour mixture. Pro tip - Once you add the flour, do not over mix as we do not want to activate the gluten in our flour.
- Finally, add the M&M candy and stir or fold gently to combine with a spatula to prevent them from breaking. Pro tip - This cookie dough can be kept in the refrigerator for up to 3 days or frozen for up to a month in freezer bags.
- Pour the batter into the prepared baking pan and spread it evenly. Sprinkle additional M&Ms on top of the dough.
- Bake in a preheated oven for 20 to 25 minutes or until the edges start to get golden brown.
- Remove and let cool in the pan for 10 minutes. While still warm, cut into 16 squares as shown in the video. Pro tip - You can sprinkle a teaspoon salt on top of the baked bars too.
- Enjoy!
Recipe Notes
- Cream the butter and sugars well so the cookie bars are soft and chewy.
- Use the right baking pan (9 x 9-inch square pan or 8 x 8- inch square pan) not more big or small. Otherwise the bars will be too thin or too thick.
- Do not over bake otherwise these will become dry very easily. It is best to underbake them rather than over bake these.
- Make sure to use a generous amount of M&M and stir them well so they are well distributed.
- Be gentle and fold the M&Ms in the dough as they bread easily.
- You can use regular or peanut butter M&Ms. You can also substitute some M&M with chocolate chips.
- Cut the bars when it is still warm that you will have less crumbs.
- Variations
- Holiday - These use only the red and green holiday M&Ms for Christmas.
- 4th of July - Using only red, white, and blue M&Ms make the perfect 4th of July cookie bars.
- Chocolate chips - Add a few white chocolate chips or dark chocolate chips to make chocolate chip M&M cookie bars.
- You can add 2 tablespoons of peanut butter to the dough to make a peanut butter M&M cookie bars
- Toffee flavor - use all dark brown sugar with melted butter for a rich toffee flavor taste in these bars
- Cookies - Of course, you can scoop this dough into cookie dough balls and bake for 10 to 12 minutes to make M&M cookies instead of bars.
