Cooking Steps

- Preheat the oven to 180°C (350°F) and position the oven rack in the center. Prepare a 23 cm x 33 cm (9-inch x 13-inch) baking sheet by lining it with parchment paper, allowing the edges to overhang slightly for easy removal.
- In a large mixing bowl, combine 240 g (2 cups) all-purpose flour, 5 g (1 teaspoon) baking soda, and 2.5 g (1/2 teaspoon) salt. Whisk together until evenly mixed. Set aside for later use.
- In a stand mixer fitted with a paddle attachment, cream together 170 g (3/4 cup) unsalted butter, softened to room temperature, and 150 g (3/4 cup) brown sugar on medium speed for 2-3 minutes until the mixture is light and fluffy. Scrape down the sides of the bowl with a rubber spatula as needed.
- Add 100 g (1/2 cup) granulated sugar, 1 large egg, and 5 ml (1 teaspoon) vanilla extract to the mixing bowl. Continue mixing on medium speed for another 1-2 minutes until fully combined. The mixture should be smooth and creamy.
- Gradually incorporate the flour mixture into the wet ingredients on low speed until just combined. Be careful not to overmix; the dough should be slightly thicker and hold together.
- Gently fold in 200 g (1 cup) M&M’s using a rubber spatula, ensuring they’re evenly distributed throughout the dough.
- Transfer the dough to the prepared baking sheet, spreading it out evenly using a wooden spoon or spatula. Use the back of the spoon to smooth the surface and ensure an even layer.
- Bake in the preheated oven for 20-25 minutes, or until the edges are lightly golden brown and the center springs back to touch. The aroma should be sweet and buttery when done.
- Remove the baking sheet from the oven and allow the cookie bars to cool in the pan on a cooling rack for 10-15 minutes. Once slightly cooled, lift the cookie bars out using the parchment overhang and transfer them to the cooling rack to cool completely.
- After at least 30 minutes of cooling, cut the bars into squares or rectangles as desired. Enjoy the warm, chewy texture paired with crunchy M&M’s.
- For best results, allow the bars to rest for an additional 10-15 minutes to firm up before serving.
Variations
- Chocolate Chip Twist: Substitute half of the M&M’s (100 g) with chocolate chips for a classic flavor enhancement.
- Peanut Butter Delight: Replace 60 g (1/4 cup) of the unsalted butter with creamy peanut butter to introduce a rich nutty flavor.
- Gluten-Free Option: Use a gluten-free all-purpose flour blend (240 g) in place of regular flour for a gluten-free treat.
- Vegan Version: Swap butter for 170 g (3/4 cup) coconut oil and replace the egg with a flax egg (1 tablespoon flaxseed meal + 2.5 tablespoons water) for a dairy-free and egg-free cookie bar.
- Seasonal Spice: Add 5 g (1 teaspoon) of cinnamon and 2.5 g (1/2 teaspoon) of nutmeg to the flour mixture for a warm, festive touch.
- Dairy-Free Alternative: Use a dairy-free butter substitute (170 g) and dairy-free M&M’s for a completely dairy-free version.
- Healthy Protein Boost: Mix in 60 g (1/2 cup) of protein powder with the flour mixture for an added protein boost.
- Microwave Version: Prepare the dough as directed, then spread it in a microwave-safe dish and cook on medium for 6-8 minutes for a quick alternative to baking.
