Is it spring yet??? Seriously! After the mildest winter I can remember, we had a week of rain, and now we’re back in the 70s and looking to hit 80 this weekend.  All the fruit trees are in full bloom and the boys are starting the slow transition to where they just actually start living outside.

I. Love. It.

I am so ready for spring.  I can’t wait to get my garden started, crank up the bbq, and start enjoying our beautiful back yard.

This past weekend Dorothy hosted a whole bunch of us Sacramento food bloggers at her house.  And not just the bloggers…nooo, the families came too!  All the kiddos had such a great time making new friends and running around like crazy people…oh, wait.  That was just my two boys :)

As you can imagine, the food was awesome! I brought these Key Lime Gooey Bars and some Veggie Crescent Bites to the party.  The gooey bars were a total hit.  Best part? Sooo easy to make!

I really amped up the lime flavor of the cake mix with some fresh lime juice and lime zest.  It really adds a punch of fresh flavor to the bars and makes them go from “good” to “wow” in a jiffy.

A sprinkle of white chocolate chips in the center adds a pop of color and texture and provides some depth of flavor to these sweet and gooey bars.  There is just no way you’re not going to love them.  Promise.

I zested another lime and some lemon to go on top of the bars.  Totally optional but it sure makes them look pretty.

These Key Lime Gooey Bars will be the perfect treat all spring and summer long! The boys are already asking for another batch :)

  9. Sweet Hannah, these need to happen in my kitchen soon! I am in love with the vibrant green color! :) And seriously, I’m jealous of your weather!!

  10. Yeah … I’ve been asking myself if it’s spring yet, too … but because we’ve had about 75 inches of snow!! And several arctic blasts – my kids have had 6 days off of school due to the cold and snow! That’s crazy! Even the local colleges have closed for most of those days! So yes … I’m super ready for spring! :)
    These key lime bars certainly look like spring to me – so fresh and light! Anything lime … that just begs to be enjoyed poolside with an umbrella in your drink!

  15. Nice recipe. Thank you Trish.

  16. Hi! I was reading the recipe and wondered if you could opt out of using foil to line a baking pan and instead just lightly spray a glass pyrex baking dish? Do you think it matters?
    Looks so good, I’m having a hard time choosing between this recipe or the strawberry lime gooey bar recipe!

  17. Can you use regular butter?

  18. They look terrific! Do you think these bars can be frozen?

  19. Girl I love these, they look amazing. Making them this week. Maybe it will bring me out of the cold weather and tired from the conference funk. xo Pinned and Yummed.

  20. HI, as I’m in Europe ánd prefer not to use any prefab mixes, how could I make these bars just from pure ingredients from scratch?
