Equipment
- 9x9-inch baking pan
- Mixing Bowls
- Whisk or spatula
- Parchment Paper
Ingredients
- 1/2 cup unsalted butter melted
- 1 large egg
- 1 cup light brown sugar packed
- 1 tablespoon vanilla extract
- 1 cup all-purpose flour
- 16 cookies Oreo crushed or chopped
- 1/2 cup M&Ms
Instructions
- Preheat your oven to 350°F (175°C). This step is crucial as it ensures even baking for the cookie bars.
- Line your 9x9 inch baking pan with parchment paper, leaving some overhang on the sides. This will make it easier to lift the bars out once they’re baked.
- In a large mixing bowl, whisk together the melted butter, egg, light brown sugar, and vanilla extract until well combined.
- Gradually add the all-purpose flour to the wet mixture, stirring gently until just combined. Avoid overmixing to keep the bars tender.
- Gently fold in the crushed Oreo cookies and M&Ms. This step is where the magic happens – you’re creating the delicious mix-ins that will make these bars irresistible.
- Spread the mixture evenly into the prepared baking pan. Bake in the preheated oven for 20-25 minutes, or until the edges are golden and the center is set.
- Once baked, remove the bars from the oven and let them cool in the pan for about 10 minutes. Then, using the parchment overhang, lift the bars out and let them cool completely on a wire rack before cutting into squares.
Notes
- Store bars in an airtight container at room temperature for up to a week for best freshness.
- Refrigerate bars for longer freshness, up to two weeks.
- Freeze bars for up to three months; thaw at room temperature before serving.
- Use gluten-free flour to make the bars gluten-free if desired.
- For clean cuts, use a sharp knife and wipe it clean between cuts.
