M&M Cookie Bars are an easy-to-make dessert that is delicious and satisfying. Making these bars ahead of time will save time and effort when you are ready to eat them. These take just 10 minutes to mix and 20 minutes to bake.
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!
