These key lime white chocolate blondies have a little tropical citrussy punch thanks to key lime zest and juice! A delicious treat that is easy to prepare.
This time of year, I am so tired of all things winter. Bring on the spring!
Problem is, in Calgary spring has a bit of a multiple personality disorder. This week we've had warm, sunny days, and then wham! Dump of snow. Fact: April brings at least one foot-tall dump of snow. We don't really do the 'April showers' thing here. 'April flurries' is more like it.
Err...yes, we are still in March. I am getting ahead of myself here. I know we have a lot of snowy/cold days ahead of us still but my mind can't help but think of fun, summery recipes...like these key lime & white chocolate blondies!
Reasons you'll ♡ these key lime white chocolate blondies
- it's a simple way to change up traditional blondies
- key lime + white chocolate are a match made in heaven
- they are simple to prepare- your kids could help you!
Four batches.
I made four batches of blondies in four days. I had two batches of incredibly 'sinky' blondies. I've had slight sinkage before but not like this. It was baaad. (I'm not sure if it had something to do with the extra moisture from the lime juice?)
So next, I omitted all baking powder & baking soda (after taking note that some blondie recipes don't use these leaveners at all). The result was a pretty dense blondie. A little too dense for me.
Finally, I added back a teensy ½ teaspoon of baking powder and found my perfect balance between sinky and dense blondies. Yay!
These blondies have some zip from the tart key lime zest and juice, which in combination with sweet white chocolate and brown sugar is just heavenly.
I really like key lime and white chocolate (see my key lime cupcakes with white chocolate frosting and salted pistachios here), but really never thought that key lime and brown sugar/buttery blondie flavors would be such a good match...well, they are!
The best thing about these blondies is how easy they are to make: the batter comes together in about 10-15 minutes, and you can mix everything by hand! Bake for 20-25 minutes, and there you are *!
I can honestly say that this recipe is nap time-friendly. Which is pretty much essential criteria for me these days!
(* If you wish, you can wait for them to cool and drizzle with melted chocolate, but it's totally optional and more for appearance than flavor).
Tips & equipment for key lime blondies
- for this recipe you will need a 9 inch baking pan and a lime zester...this is my favorite microplane!
- make sure to use a metal baking pan; if you use a glass baking pan, line it with foil and add an extra 5 minutes onto the cook time.

I made these blondies on a whim for a friend’s bday who loved key lime pie but logistically we needed something more travel friendly. They were the hit of the trip! So dang easy, quick, and incredibly delicious. I’ve never gotten more compliments on a baked good!
