Cake Mix Blondies (with Maple Butter Sauce)

These white chocolate Cake Mix Blondies with Maple Butter Sauce are a shortcut version of a favorite dessert at Applebee’s.

AN EASY BLONDIE RECIPE WITH A DELICIOUS SAUCE!

I am always looking for ways to make my favorite desserts a little faster. I have a ‘from-scratch’ recipe for this that I really enjoy. But I don’t make it that often because it takes more time and energy than I sometimes have. So this quicker recipe is my solution and yes, it starts off with a boxed cake mix.

TIPS FOR MAKING CAKE MIX BLONDIES

  • If you absolutely insist on making it from scratch, give my Homemade. Blondie Recipe a try!
  • Also, I am using white chocolate chips and walnuts but you can use any combination of chocolate chips or nuts that you enjoy. This is a fun recipe to experiment with and change up the flavors.
  • If you’d like thicker blondies, just make in a smaller baking dish and adjust baking time accordingly.
  • Updated to add: cake mixes seem to keep reducing in size over the years. They used to be 18.25 ounces and now some of them are down to 14 ounces so baking times will vary depending on the type of cake mix you purchase and how much is in the box. So please understand this before baking. You will need to keep an eye on it. Start with about 15-18 minutes and go from there.

HOW TO MAKE CAKE MIX BLONDIES:

Preheat oven to 350F degrees. Spray 9×13-inch with nonstick cooking spray (I like to use the kind that has flour in it). In a medium bowl, combine cake mix, eggs and melted butter until combined. This will blend easier using an electric mixer.

Spread mixture evenly into pan. I like to spray my hands with a little of the nonstick spray, and then spread it out using my hands. It just makes it much easier.

    I took this as my contribution to a work Thanksgiving potluck. They were so simple to make and serve and everyone absolutely devoured them. Also, that sauce is flipping AMAZING! It really is the perfect complement to the blondies. I’m not a great baker so this was perfect for me – thank you!!

  2. Yes, I just commented on the awesome mac and cheese recipe 🙂 however, I also made this for dessert yesterday and loved it!! It's better than Applebee's and much cheaper!! Maybe you could just plan my dinner menu… just a thought…. 🙂

  3. Awww shucks – thank you! Applebee's was my inspiration but I also wanted to keep it easy! So glad you liked it!!

  4. This may be a lazy baker recipe but the idea to pair blondies with a maple butter sauce sounds like a serious treat!!!

    Brandie, these look amazing! Why bother with baking from scratch when you make something this delicious so easily. I'm sold. In fact, I'm pinning it to make for the family. They will LOVE it. Thanks for sharing your recipe and have a great weekend!
