What’s the Difference between a Blondie and a Brownie?
The main difference between blondies and brownies is brownies have the addition of chocolate whether melted or in cocoa form and blondies are rich in buttery, brown sugar and vanilla flavors.
I don’t shy away from chocolate recipes, like my easy One Bowl Brownies, my Triple Chocolate Dream Torte, or this incredibly easy Chocolate Chocolate Chip Bundt cake.
BUT, blondies take the cake for me, or the bar cookie, or whatever…blondies rock! Even my husband, a chocolate lover, loves these — he calls them “Fat Pills!” 😉
Fresh Tips for the Best Chewy Blondie Recipe
- Melt the butter | I’ve made these with regular melted butter as well as Browned Butter (see post on Brown Butter Glaze for simple how to make brown butter), I think browned butter is my fave, but it’s an extra step, so I get it you just need to get these in your belly! Psst…please use REAL BUTTER, real butter means it’s hard coming out of the fridge, if it’s in a tub or is soft out of the fridge it’s not real butter, but a blend.
- Extra Egg Yolk | Adding an extra egg yolk adds a bit more fat content and emulsifying abilities to the batter; some people have complained that when they make blondies, the fat separates and floats to the top while baking. The fat gives baked goods extra-rich flavor and a velvety texture. The yolk also has the unique ability to bind liquids and fats together, creating an emulsion that prevents them from separating.

Whether you are at sea level, 1,000 feet or 8,500 feet, do not over bake your blondie bars! Remove from the oven when the edges are just turning golden, pulling away slightly from the edge of the pan, and the center still looks slightly unbaked. They will firm up as they cool.
Simple Ingredients for Blondie Bars
- Butter | The real stuff, nothing soft coming from the fridge. Melted!
- All-Purpose Flour | I used organic unbleached all purpose flour, I have found unbleached works best in baking.
- Brown Sugar | I used light brown, but for a more caramel flavor you could certainly use dark brown.
- Eggs | You need some lift and chew with your chewy blondies, the eggs help!
- Mix-Ins | see above for ideas, I have used butterscotch chips, Heath bar bits, chocolate chips, and malted milk balls.

Mix-in ideas for blondie bars
Rule of thumb, add up to 2 cups of your favorite mix-ins, as few as ½ cup or none at all, you design this designer gooey cookie bar!
- Chocolate Chip Cookie Bars | add up to two cups semi-sweet chocolate chips
- Butterscotch Blondies | Add up to 2 cups butterscotch chips
- Toffee Blondies | Add one 10 oz bag Heath bar toffee bits (I used Heath bits and butterscotch chips in this batch below! WOW!)
- Got Nuts | Add chopped walnut, hazelnuts, macadamia nuts, or pecans — or your favorite nuts or chips!
- White Chocolate Chips, Dried Cranberries or Cherries or other dried fruit and walnuts would make a spectacular blondie cookie
- M&M’s, mini Reese’s, Mini Rolo’s, Caramel pieces or chunks, Mini Snickers, or Peanut Butter Chips
- Whopper or Malteser Blondies | My personal favorite! Crush or chop 2 cups of malted milk balls in ziplock baggie and mix in. Optional | press whole malted milk balls into just out of the oven blondies and sprinkle with a little flaky sea salt!
How to make this chewy blondie recipe
Start by melting the butter (and browning if you choose to do brown butter blondies), in a large mixing bowl or the bowl of a stand mixer, add brown sugar and melted butter and stir until smooth.
Add eggs one at a time, mixing in well after each addition. Stir in vanilla extract. In a separate bowl, whisk together flour, baking powder and salt.
Stir in flour mixture one cup at a time, mixing into the wet mixture a little at a time, until completely combined. Add desired mix-ins (chips, nuts, toffee, etc) stirring until mixed.

Spread batter into parchment or foil lined pan (for easier slicing). To easily “spread” batter, scoop batter into prepared pan and using a piece of parchment, wax paper or plastic wrap, lay over top of batter and smooth to edges of pan until even, see video below for how I do it.
For thinner (but more of them) blondies use 9×13 inch pan, for thicker chewier blondies use a 9×9 inch pan or 7×11 brownie pan.
Fresh Tips
- Brown Sugar | I have used all light brown sugar, half light and half dark brown sugar, the key is to use brown sugar, this gives the blondies that carmel-y, buttery chewiness!
- BAKING TIME!! | This is probably the most critical aspect, I have overbaked many a blondie (or brownie for that matter). Baked goods tend to bake faster at high altitude so I typically start checking my baked goods about 10 minutes before the lowest time given.
Bake at 350° F (175° C) (Sea Level up to 3500 feet)
- 9×13 inch pan 18-25 minutes
- 9×9 or 7×11 inch pan 25-35 minutes
Cool soft and chewy blondies on a wire rack; once completely cooled, use the parchment paper to lift them out and cut into squares.
High Altitude for the best chewy blondie recipe
- Increase heat to 375° F (190° C) if using metal, regular pans (if dark or glass pans; keep temp at 350° F)
- 9×13 inch pan bake for 15-25 minutes
- 9×9 or 7×11 inch pans 20-30 minutes
Storage Tips
Store completely cooled blondies on the counter in an airtight container up to 4 days. Some say placing a piece of bread in with the blondies will keep them moist longer.
For longer storage, store in the refrigerator (up to 7 days) or freeze for up to three months. These will thaw quickly at room temperature. Or for an extra gooey treat, microwave them for a few seconds.
Using real butter and the best ingredients you can afford will give you the best blondies! And here’s a tip: don’t be afraid to take them out of the oven a tad early – they’ll firm up as they cool, keeping that chewiness intact.
Absolutely! Chewy blondies are versatile and can be customized with various mix-ins such as chocolate chips, nuts, dried fruits, or even candies. Ensure that the mix-ins are evenly distributed throughout the batter to enhance the overall flavor and texture of the blondies.

Christine
Based on the last two comments and my own results, I think there’s simply too much flour for these to be chewy. Next time I will cut down on the flour by at least half a cup.
I’m so sorry you had that experience Christine. My experience is over baking removes the chewiness and makes them cakey. Let me know if you try with less flour though!
Taylor
Mine came out cakey rather than gooey like a brownie. Not sure what I did wrong….
Usually too cakey comes from over baking them, or your oven might run hotter than it says. That’s pretty common! But darn! Sorry about that!
Leah
I’ve made these twice now. And they came out cakey both times. I even cut the baking powder down. I’ll try lowering the oven temp next time, super bummed though.
So sorry about that Leah, hate it when we use expensive ingredients and it doesn’t turn out.
Sounds like you’ve been over baking them, try taking them out 5-8 before you think they are done. It could also be that your oven needs calibrating- most ovens run hot or cold so it’s easy to over bake. They should still look somewhat raw, they’ll keep baking as they cook in the pan.

About to make these for the SECOND time!! I love them! My mix ins are peanut butter chips, chocolate chips and walnuts! So easy to make and so so so good!
Yay!! That makes me so happy Elizabeth!
Elizabeth
Doing this recipe again for the family since it’s such a big hit! Had several fresh blueberries from the garden this year so mix ins this time are blueberries, choc chips, and walnuts! 😍 super excited for the results

These Blondies are the best! So easy and delicious with the browned butter! I mixed chocolate chips, butterscotch and chopped pecans. I need to give some away before eat the whole pan on this snowy day.
Haha! RIGHT!? My husband takes all my extra goodies to the guys at work! Thanks for the kind comment!

First you had me at brown butter…but I quickly moved into toffee chips and malted milk balls. I made a pan of these into bars and they disappeared in a nanosecond!
