RECIPE WALK-THROUGH
How To Make Blondies
See the recipe card below for full, detailed instructions
Preheat oven to 350°F and spray an 8”x8” baking dish with non-stick spray.
Add the wet ingredients (melted butter, brown sugar, egg, and vanilla) to a large bowl and whisk until combined.
Add the dry ingredients (flour, baking powder, and salt) and mix until combined.
Pour batter into the baking dish and bake for 20-25 minutes, until a toothpick inserted into the center comes out clean.
Cool completely, cut into bars, and serve!
Serving Suggestions
Once they’ve cooled, cut the blondies into squares or triangles and enjoy them as is, or go all out and top with a scoop of vanilla ice cream or whipped cream and a little caramel drizzle!
Storage Tips
The Best Way to Store Leftovers
Blondies can be stored covered at room temperature for 3 days.
To freeze: Wrap squares tightly in plastic wrap, followed by foil, and freeze in a freezer bag for up to 1 month. Foil helps prevent freezer burn better than plastic wrap alone.
Recipe Tips
- For perfectly gooey blondies, check them after 20-25 minutes, the edges should appear cooked and crispy, and the toothpick will come out with some wet crumbs on it.
- Mix-ins are completely optional. I recommend adding a heaping ½ cup of mix-ins (no more than ¾ cup TOTAL) of any combination you’d like. Some suggestions: chocolate chips (dark, semi sweet, or milk), white chocolate chips, peanut butter chips, butterscotch chips, mini marshmallows, pecans, walnuts, cranberries, and crushed pretzels.
- Sprinkle with a bit of sea salt after baking if desired.

I absolutely love this recipe! The blondies come out absolutely amazingly sold and chewy, but I would have to reccomend that you use 1/2 tsp to 3/4 tsp of salt because my batter was a bit too salty. I would also suggest that you make this in a smaller pan as I used a 8 by 5 inch pan and they were still a bit thin.
Thanks for sharing your honest feedback Tuba! Glad you enjoyed the blondies.
YUmmy! Tried this recipe. Just reduce sugar because my aunt doesn’t like too sweet. It’s awesome
These have become a go to for me and they are a hit with everyone who tries them! Super easy to make, would highly recommend.
Awesome feedback Amy! Thanks for stopping by.
Can i mix this by hand? Or does it have to be with a mixer?
You can mix by hand with a wooden spoon. I use a hand mixer because it goes a little faster and it easier to stir.
Thanks, Kristin! Darling little recipe when my pantry is not full. Perfect for something sweet while
staying in and making do. I added some chopped walnuts from the freezer.
Easy, few ingredients and comes together fast.
Nice! Glad it worked out for you Gail. Thanks for stopping by.
Perfect and easy!
Thank you Holly!
Theses have become my go to when I need to make a desert for any thing…My family loves them I have made them with butterscotch chips and have also made them with caramel swirled o top.
Nice! Thanks for stopping by Kathleen.
omg so good, i totally would make this again, i loved it
That’s awesome Susan! Thanks for stopping by.
I bake these for 30 minutes like the instructions said let them cool and they were still real gooey in the middle. I used an 8 by 8 pan baked according to the instructions. Why did this happen?
It’s tough to say since I wasn’t in the kitchen with you. Best guess it could be that your oven temp is a little off.
Hi there! I’ve made these before and they’re delicious! I’m looking to try something new, do you think I could swirl salted caramel through these before baking, or would that throw off the texture? Thanks!
I think it’s worth a try!
Hi, I’ve made these twice now. After making them with sun flower/olive oil. I got the aroma of apple pie. Do you have an idea of how to add actual apples into the mix?
I’d worry they would give off two much liquid. But maybe try replacing the oil with apple butter. That would probably be delicious. If you do try regular apple, be sure to cut them into very small pieces and remove the skins first. You might also cut the vegetable oil slightly to make up for the extra liquid. These are just suggestions, I haven’t tested this myself so I don’t know for sure how it would turn out.
I could suggest you to precook the apple to make to dehydrate it
Was a hit with my spouse, who hates sweets.
I didn’t think they were too salty and it also took 40 mins in an 8×8 pan. I added two handfuls of semi sweet chocolate chips. Turned out great! I think next time I will double the batter and make in a 9×13 pan.
Thank you!!!
That’s awesome Michael! thanks for stopping by.
I made them a week ago, and I’m making them again today– the only thing I did different was add 3/4 cup dark chocolate chips. DELICIOUS !
awesome! thanks for stopping by.
everyone’s saying they’re too salty but i used the full teaspoon and sprinkled kosher salt on top and i think they were fine ? i added chocolate chips though because i love salty chocolate chip anything. so good they stayed really soft but i did have to bake for 40 mins in the 8×8.
Thank you Amber! and thanks for sharing your experience!
Hi! I made these Blondies and substituted Gluten Free flour and used the 1/2 tsp Salt. I use this flour in other baked goods all the time and usually everything turns out alright. The flavor is ok but they seem a little uhm… dense. Could this be an indication that I mixed the batter too long?
Using any ingredients other than those specified in the recipe can yield a less than desirable result. Substituting the flour may be fine in some recipes and not so much in others.
Agreed. Sometimes it doesn’t work. They were great the next day. I’m keeping the recipe and will try again another day.
Which gluten free flour do you use? I’m looking for one that works with baking for my mom. I’ve tried some flours before that ruined every recipe. Thanks!
Hello Ava!
I actually use Bob’s Red Mill Gluten Free 1 to 1 All purpose flour. It is a light blue bag and everything I bake as far as cakes and cookies go turn out very well. I have found that cake recipes work much better with a 15 minute rest prior to going in the oven. (A word of caution dont use Bobs yellow bag GF flour. It is made with beans and will ruin the flavor of every thing you try to make with it.
This was a really good base recipe. I followed it almost exactly but i ran out of vanilla extract so used half vanilla and half almond extract. And halved the amount of salt based on other reviews. I had odds and ends of different types of chips and nuts left over from holiday baking so added them and the result was a light and tasty blondie bar. Thank you for a great recipe i will use for years to come!
Thank you Michele! I love that you were able to make it work for you!
These were wonderful! Easy to make and even easier to eat! Will definitely make them again and again.
Thank you Sue!
Wow turned out amazing! I used a little less salt like the comments say and it was really good! Thanks!!
These turned out disappointingly salty. I’m glad I made a test batch before serving them to anyone else, because unfortunately I didn’t read the comments first. As another poster said, this might be good with just 1/2 or 1/4 tsp of salt. I likely won’t be trying this recipe again.
Sorry the recipe didn’t work out for you HB, but thanks for sharing your feedback.
These are VERY salty. I recommend only using 1/2 tsp of salt. Maybe even only 1/4 tsp. If I use this recipe again, I’ll experiment with it and let you know.
I love blondies even more than I like brownies! It’s the ultimate treat ♥ Looks sensational!
