I really love how easy this recipe is too. You mix together some ingredients, throw them in a pan, and then bake. If you’d like, you can even freeze these for later as they do freeze pretty well.

If you’re making these for a party, you might want to double this recipe as they will go quickly. They’re delicious and a real crowd-pleaser recipe.

This is even a great recipe for if you’ve somehow ended up with lots of spice cake mix that you never ended up using (I can’t be the only one who does that, can I?). Instead of mixing up a cake, why not track down some recipes using spice cake mix? These cream cheese bars are a very delicious option.

Boxed spice cake mix recipes are pretty delicious when you just don’t want the cake. But if you want to make your own cake mix? You can do that too – the cake mix just makes it easier.

Mixing Harvest Spice Bar Ingredients

How to make harvest spice bars

  1. PREPARE: Preheat the oven to 350F and add some parchment paper to the bottom of your favorite 9×13 baking dish.
  2. MIX DOUGH: Mix the cake mix, butter, and egg until well combined and then press into the bottom of your baking dish.
  3. MIX TOPPING: In another mixing bowl, beat the cream cheese until smooth and then beat in the eggs, one at a time. Beat in the butter and vanilla until smooth. Slowly add the powdered sugar until well combined.
  4. BAKE: Pour the topping over the crust and then bake for 50-60 minutes or until the edges are firm – the middle should still slightly jiggle.
  5. SERVE: Cool completely before cutting into 2-inch squares and enjoy!

Can I use salted butter for this recipe?

I would not recommend it, no. The contents of the butter has an undetermined amount of salt that may change the taste profile of these spice bars. I always recommend using unsalted butter for baking.

What is the best way to soften cream cheese?

You definitely don’t want to skip out on making sure your cream cheese is nice and soft! If you’ve never tried to beat cream cheese that wasn’t first softened, it can be a real pain.

You can soften cream cheese one of two ways: leave it out for an hour prior to baking, or microwave it for about 10 seconds, until it’s softened enough to beat in your mixer. (This is the easiest way as I know I’m always forgetting to pull out the cream cheese to soften!)

How long will these spice bars last?

These will last about 3 days stored in an airtight container, left out on the counter or stored in the fridge.

Can I freeze them for later?

YES! You can put it in a plastic bag as a whole or cut them up and put them in individually. They will last for about a month in the freezer – perfect amount of time to bake ahead of time for holiday parties.

  1. Do you use 2 cake mixes or one? The ingredients say 2, but the directions say “the cake mix”. These bars sound very yummy!!! Spice cakes are so tasty.

  2. Do those 2 layers really bake into the “4 layers” that it looks like in your picture? What size pan? A 9×13? This looks and sounds delicious. I think I will make these for my co-workers. (This way I get to indulge, but not have the entire pan to eat for myself). 😉 Thanks, Jaclyn!

    1. Yes, these bars are made in a 9 x 13 in baking pan. I can’t believe I left the size of the pan out of the recipe — thanks for pointing that out!

      Although the bars look like they have 4 layers, they really are made of just 2 layers: the bottom spice cake mix “crust” layer and the cream cheese mixture top layer. The top of the bars turn a nice golden brown and crisp up while the middle of the bars are more ooey-gooey. I hope this makes sense!!

      They are really tasty bars and perfect for Fall and Thanksgiving. I hope you & your co-workers enjoy them!

  3. Hello,
    These sound delish!
    Making these for Thanksgiving. I have plenty of “extra large” eggs. Can I use these instead of large?

  4. I make these with the same ingredients but only use 1 box of spice cake in a 9×13 pan. At first I thought I misread the ingredients when it said 2 boxes of spice cake mix. Your recipe must have a much thicker crust?

  5. So easy to make, makes a large amount, absolutely delicious but very sweet. Still have some left from last week and still great. Huge hit when I took it to work, have now been asked when am I bringing more and that I should start charging for them! haha. Will definitely make again!
