Pumpkin Spice Cake Bars

All too often I take the long way around, but I’m slowly learning some kitchen hacks that save time and still give the delicious and mouthwatering results that my family loves. Scott is great at doing this very thing in the kitchen, and even he endorsed this fall dessert recipe, as evidenced by repeated trips to the baking pan for “just one more.”

Don’t get me wrong, he wasn’t the only member of the household to fully loved these Pumpkin Spice Cake Bars. Aside from yours truly, the rest of the boys in the household all gave this one a thumbs up. I think you will too when you find out just how easy and tasty these are to enjoy.

These Pumpkin Spice Cake Bars start with a spice cake mix from a box. Part of the mix acts as a base and the other half is added to the next layer which is combined with packed pumpkin and sweetened condensed milk. Hopefully, your salivary glands are starting to kick in, and you are beginning to get the picture.

There’s more though! We toasted some walnut pieces to add to the base; these provide a bit more structure and of course their warm flavor. Many times, our boys don’t care for nuts in their desserts. There was nary a word of opposition in this case. Of course as with any recipe, nuts are entirely optional for those with allergies or other aversions to them.

Finally, these Pumpkin Spice Cake Bars are topped with a simple toasted oatmeal streusel. If you’re like this family and you usually have ice cream in the freezer, it would be nothing less than unnatural to omit a generous scoop of that as well. You can see from the photos that we go the natural route as much as possible. Try these Pumpkin Spice Cake Bars, they are sure to be a fall and holiday standard in our family and likely yours as well.  -Dan

    Baking this in Denver CO. The last half took approximately 20 – 25 minutes to set. I agree some kind of baking time range would be helpful.

    1. Thanks for the input for this pumpkin dessert, Marian. We will make some revisions to include this information. We really appreciate your feedback!

    1. Hi Cindy. I couldn’t agree more with you, a baking time would indeed have been appreciated for the second part of this recipe. Sadly, there is no specific time for when the bars will be done, at that point. Rather, your senses and feel for the end product have to come into play here, with some diligent attention to what is going on inside of the oven. To reiterate, per the recipe’s instructions, they are done and ready to come out when the streusel has set and the top is a golden brown.

        1. Thanks for the comments, Holly. I can’t for the life of me think of any dessert bar that would need an additional hour’s baking time. That being said, these bars spend 15 minutes for the initial part of their baking process. After the streusel topping is placed on top of the bars, an additional 5 to 8 minutes should be all that is necessary until the bars have set and they are ready to come out of the oven. Most importantly, because baking time can vary due to factors such as oven variability and altitude, monitor the bars and when they appear firm and set in the center then they will be ready to enjoy.

  2. These sound and look outstanding! Love that streusel topping, too. They seem like they would been super moist, yet still cakey enough to hold up. Thanks!
