How To Make 4th of July Monster Cookies – Browned Butter Blondie Step by Step
- Preheat your oven to 350°F (175°C) and line a 9×13 inch baking pan with parchment paper for easy removal.
- In a saucepan over medium heat, melt the butter and cook until it turns golden brown and develops a nutty aroma, about 5-7 minutes. Remove from heat and let it cool slightly.
- In a large mixing bowl, whisk together the browned butter, brown sugar, and granulated sugar until smooth and well combined.
- Add the eggs, one at a time, mixing well after each addition. Stir in the vanilla extract for a touch of warm sweetness.
- In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt to evenly distribute the dry ingredients.
- Gradually add the dry mixture to the wet mixture, stirring until just combined. Avoid overmixing to maintain a soft, chewy texture.
- Fold in the white chocolate chips, red and blue M&M’s, and chopped nuts if using, ensuring even distribution throughout the batter.
- Pour the batter into the prepared baking pan and spread it evenly using a spatula.
- Bake for 25-30 minutes, or until the edges are golden and a toothpick inserted in the center comes out clean.
- Let the blondies cool in the pan for 10 minutes before lifting them out using the parchment paper. Slice into squares and serve warm or at room temperature.

Expert Tips for Perfect Blondies
- Cool the browned butter: Allow the butter to cool slightly before adding it to the sugar mixture. This prevents the eggs from scrambling while incorporating a smoother texture.
- Don’t overmix: Stir the dry and wet ingredients until just combined. Overmixing can lead to tougher blondies due to gluten development.
- Use parchment paper: Lining the baking pan ensures your blondies come out cleanly without sticking. It also makes cutting easier.
- Keep an eye on baking time: Check your blondies at the 25-minute mark to avoid overbaking. The edges should be golden while the center remains slightly soft.
Frequently Asked Questions
- Can I make this gluten-free? Yes, substitute the all-purpose flour with a 1:1 gluten-free baking flour blend for similar results.
- What other mix-ins can I use besides M&M’s? Try swapping the M&M’s for sprinkles, peanut butter chips, or dark chocolate chunks to suit your preferences.
- How do I adjust for high-altitude baking? Add an extra tablespoon of flour and slightly reduce the sugar to account for the change in baking conditions.

Common Mistakes to Avoid
- Skipping the parchment paper: Without it, removing the blondies can be difficult and messy. Always line your pan for easy cleanup.
- Not browning the butter properly: Undercooking the butter means missing out on its nutty, rich flavor. Wait until it turns golden brown for the best results.
- Overbaking: Baking too long can dry out the blondies. Check at the 25-minute mark and remove once a toothpick comes out clean.
