Ingredients
Wet Ingredients
- 200 g Butter (melted)
- 2 Eggs
- 2 tsp Vanilla Extract
Dry Ingredients
- 125 g Golden Caster Sugar (or white caster sugar)
- 125 g Light Brown Sugar
- 275 g Plain Flour (all-purpose flour)
Mix-ins
- 150 g M&M Chocolate Bar (cut into chunks or use chocolate chips)
- 150 g M&M's (chocolate flavor or preferred)
- 50 g M&M's (crispy or any flavor)
Instructions
- Preheat and Prepare Tin: Preheat your oven to 180°C (160°C fan / 350°F / Gas Mark 4). Line a 20cm (8") square baking tin or a small brownie tin with parchment paper, leaving an overhang for easy removal after baking.
- Cream Butter and Sugars: In a large mixing bowl, cream together the melted butter, golden caster sugar, and light brown sugar until the mixture turns pale and fluffy, indicating the sugars have dissolved and air has been incorporated.
- Incorporate Eggs and Vanilla: Beat the eggs and vanilla extract into the creamed butter and sugar mixture until fully combined, resulting in a smooth batter base.
- Add Flour: Gradually stir in the plain flour until a soft cookie dough forms. Make sure no streaks of flour remain, ensuring even mixing.
- Fold in Mix-ins: Gently fold in the 150g of M&M chocolate chunks (or chocolate chips) along with 150g of M&M's and 50g of additional M&M's, distributing them evenly throughout the dough.
- Transfer and Smooth: Spoon the cookie dough into the lined baking tin, spreading it evenly and smoothing the top with the back of a spoon or spatula for an even bake.
- Bake: Bake in the preheated oven for 30 minutes, or until the edges turn golden brown and the center is just set, ensuring a chewy texture. Remove from the oven.
- Add Extra M&M's and Cool: While still warm, gently press a few extra M&M's on top for a decorative finish. Allow the cookie bars to cool completely in the tin before lifting them out using the parchment overhang and slicing into bars.
Notes
- Use parchment paper with an overhang for easy removal of the cookie bars from the tin.
- Pressing extra M&M's on top before cooling adds a colorful and appealing presentation.
- For a different texture, substitute some M&M's with chocolate chips or chunks as preferred.
- Ensure not to overbake to maintain a chewy center; bars will firm up as they cool.
- Store cooled bars in an airtight container at room temperature for up to 5 days.
