Ingredient Notes
Full ingredient measurements and instructions can be found in the recipe card below.
- Butter: You will be browning the butter and letting it cool.
- Brown Sugar: We stick to all brown sugar in these to keep them extra chewy.
- Cornstarch: This will help to keep these bars extra soft.
- M&M's: Use any kind you love in these. I used the plain milk chocolate.

Recipe Instructions
Step 1: Start by browning the butter. You'll take ½ cup of butter and melt in a medium saucepan, and then continue to cook past the point of boiling. You will do this over medium heat, past the point of the butter foaming, until it turns a nice golden brown, and has a nutty smell. Make sure you are stirring and watching it, because it will turn from perfectly brown to burnt fairly quickly. Once finished browning, pour into a cup or bowl and allow to cool.
Step 2: Preheat oven to 350 F, and line an 8x8 baking pan with cooking spray and parchment paper.
Step 3: In a medium bowl, whisk together browned butter and brown sugar until combined. Add egg, yolk and vanilla and mix until combined.


Step 4: Stir in cornstarch, salt and flour. Then very carefully fold in m&m's and chocolate chips.


Step 5: Pour into prepared baking pan and smooth with a spatula to make even for baking. Top with a few more m&m's and flaked salt.
Step 6: Bake for 20-23 minutes or until light golden brown along the edges. Allow to cool before serving.


Expert Baking Tips
- You want to make sure and not over bake these. They will continue to set up as they cool.
- Add in ¼ cup of red and green sprinkles for extra holiday fun!
- I have given both cups and grams as measurements. Grams will be more precise, especially when measuring flour. If you don’t have a kitchen scale, no problem! Just lightly spoon flour into your measuring cup to insure its not packed in there. Light and fluffy is the key.

FAQ
Blondies, aka blonde brownies, are much like a chocolate brownie, but don't use any chocolate or cocoa powder. Using brown sugar and vanilla gives them a very rich buttery, vanilla flavor.
Blondies should be very chewy and fudgy. If they are hard, they have been cooked too long. Then baking they should turn a light golden brown along the edges, this means they are done. You will want to allow them to cool completely before cutting into them as the center might be gooey before cooling.
No, you can just melt the butter instead and still allow to cool.

Storing & Freezing
These chewy Christmas blondies can be stored in an air tight container for 3-4 days on the counter.
Blondies are perfect for freezing. If stored in an air tight container they will stay fresh for 3-4 months. I even enjoy eating mine right out of the freezer because they are so gooey they don't turn rock hard frozen.

These were super easy to pull together and such a time saver to do a bar type cookie! They baked up beautifully and were the perfect addition to my cookie platter this year.

Wow these really are the chewiest! I was worried they weren’t cooked the whole way through, but they were. I think the browned butter is a major flavor factor in these. So good. Only downfall is they don’t make many cookiesmm
Jenna Rogers
Oh. My. Gosh. These were delicious! They came out perfectly gooey and the M&Ms give a nice little crunch. Will bake again!

So chewy and delicious! I had to bake mine longer than the recipe called. May have been due to elevation or user error.

These are really good. However, a little too sweet for me. I would leave out the chocolate chips next time. Great blondie base though to try diff add ins.
