These blondie cookies are one of the easiest cookie recipes you can make! They are mixed together in one bowl and baked in one pan! It doesn’t get easier than that. They can be made either super gooey or cakey depending on how you like them, and you can add any kind of topping you like!

Blondie cookies
Honestly, these are my go to dessert when I need something delicious, fast, and for a crowd. These guys come together in a mixing bowl in literally 5 minutes and depending on the pan size you use, can be baked in 25.
These cookies are thick, chewy, and full of chocolate- no-one can resist!
How to make the cookies
Like I said, you only need ONE BOWL!
Make sure the bowl you are using is microwavable though.
To start, melt the butter in the bowl and let it cool for 5 minutes. Then add in the sugar, eggs, and vanilla. Whisk together until combined.
Add the flour, baking soda, and salt and mix until combined. Then add in the chocolate chips and stir with a wooden spoon or spatula. Spray a 9×13 or an 8×8 inch pan with baking spray or line with parchment paper, fill and bake!
Making these dairy free
If you want to make these dairy free- you can substitute the butter for Earth Balance or another butter substitute and use non dairy chocolate chips.
Baking times:
The size of the pan will determine how long you need to bake.
If you are using a 9×13″ pan, bake them for 25- 30 minutes. If you are using an 8×8″ pan, they will need longer, about 35- 45 mins.
I have an electric oven and bake these in a ceramic 8×8 pan always for 35 minutes. Your bake time might be longer depending on:
- Your type of oven- if you have a gas oven, you may need longer
- The type and color of your pan. If you have a dark metal pan the blondies will bake quicker than a glass or light metal pan.
- What consistency you like
If you like blondies more on the gooey side then they will need less time. If you like them more on the done and “cakey” side, bake them for longer.
You’ll know the blondies are done when the edges are golden brown and the top is crinkled! You can press down lightly with your finger in the middle.
If it’s firm, they are definitely done!
Using other add-ins:
You can definitely use other things to mix into these blondies. Here are some ideas:
- white chocolate chips (see above pic!)
- nuts
- m&m’s
- a combination of all three
- caramels
- toffee bits
- shredded coconut
- basically anything
This recipe is so versatile, you can really bake anything you would in another cookie, brownie, or other blondie recipe in here.
Because honestly what is a blondie anyway? It’s the opposite of a brownie!
Making these ahead
You can for sure make these guys ahead- I would suggest only a day before if you don’t want to freeze them. A quick 45 seconds-1 minute in the microwave will warm them right up if you want to serve them warm the next day.
Tips on freezing
Let the blondies come to room temperature.
If you want to freeze them without the pan- turn it upside down so the blondies come out in one piece. Wrap the whole thing in tin foil and then plastic wrap and freeze for up to 2 months. Don’t cut them before freezing!
To freeze these in the pan- follow the same method above but don’t turn them out!
Make sure to defrost the blondies on the counter before cutting them- and save yourself an extra piece, they are that good!

- 1 ½ cups granulated sugar
- 2 eggs large
- 1 tablespoon vanilla extract
- 2 cups all purpose flour
- ½ tsp baking powder
- Pinch kosher salt
- 1 bag chocolate chips 10-12 oz or other toppings!
Instructions
- Preheat the oven to 350° F. Spray an 8x8 or 9x13 inch pan with baking spray or line with parchment paper.
- In a large microwavable bowl melt the 1 cup butter, then cool for 2 minutes. Add the 1.5 cups sugar, 2 eggs, and 1 tbsp vanilla, and whisk until frothy and combined well.

For some reason mine took FOREVER to bake. I live at 5400 feet but I set the oven to 375 F and them 55 min in an 8×8 pan. Have no idea why this happened. Still tastsy as all get out though
Thanks Emma! Not sure why they took so long I don’t ever bake them longer than 35 mins. Glad to hear they still turned out ok!!
Already made it! Delicious and so simple!
Thank you so much Debby! All about those simple but delish desserts!!!
Yuuummmmm!!!!
Thank you so much Michelle!!!
If I wanted to add oatmeal to these, how much would you suggest? Thanks!
Hi Miranda! I havent tried it, but you can start with a 1/4 cup and see how it goes! You might have to decrease the amount of flour or it can come out to dry. Hope it works!
If you’re into indulgence (and you should be) these are the blondies for you! So chewy, perfectly sweet. Absolutely going on rotation at my house.
UGH I JUST LOVE YOU!
Made these tonight! Soooo good!!! And super easy, a definite favorite! Thank you!
Wohoo!! So happy to hear that, thank you so much for making these!!
SO GOOD!!! I’m all about simple + delicious recipes, so when I kept seeing these lil guys I had to jump on the blondie train. Let me tell you – they are a party! I used espresso chocolate chunks + oreos …omg 🤤 thanks Sam you rock!
Amazing and I added a little instant expresso because I can’t go with out a little coffee with my chocolate!
That is so smart! Thank you so much for making them!!
Chewy for sure, I can guarantee it.
The final product was amazing, not exactly what i expected as they didnt cook after 25 mns, so unable to cut them in squares.
But I added ice cream and for once I let the kids dig in with the spoon as the dough was not cooked through and we just enjoyed the whole mix. I added mini marshmallows and mixed chocolate chips.
Don t really know why it didnt cook through , but will give it a try again in the fall.
Thank you so much .
Hey Monica! Thank you so much for your 5 star review! I have recently updated the post to reflect different baking times per pan. Sometimes the differences in pans and ovens yield different results. I am so glad you were still able to enjoy them, thank you so much!!
These are amaaaaazing! Perfectly chewy and easy to make! I made them with my 5 year old cousin, and they were simple enough for him to do most of the work. Will definitely be making again!
Thank you so much Andrea! I am so happy you and your nephew enjoyed these!!!
Soooo good! Love this recipe, Sam. I’d definitely say that the texture is a cross between cake and brownies. I used mini m&ms and the blondies were perfect right out of the oven. Will definitely make again.
Amazing Ashley! Such a good addition, im gonna do that next!! Thanks so much for your comment and review!!
Very simple recipe, my son loved it but I found it a bit too sweet. Will try using less sugar and vanilla extract next time
Thank you for making them Lisa!
These are fantastic!! Love the texture and the amount of chocolate goodness 🙂 I added brown butter and let it cool completely before adding and it tasted great! Thanks Sam :))
What a great addition!! Thank you so much for making these I am so glad you loved them!
Hi! Is this worth doubling when baking in a 9×13 pan? I’m interested in whipping these up for a BBQ, but need a good number of them, yet I don’t want to miss out on the thickness you’d get from an 8×8 pan.
Thanks in advance!
Hi! They definitely will be less chunky if you bake them in 9×13 (lesson the time to 20 minutes or so) you can also bake them in a double batch if you want and bake them for a bit longer!
Good recipe but needed more salt, I would add one 1 tsp of salt next
Thanks for making them!
