These Raspberry Bars are as easy as can be to make! This recipe uses cake mix, oats, and brown sugar to create a delicious crumble topping over the top of a raspberry jam filling.

I feel like we’re pretty much stuck in an endless winter situation here in Ohio.

Yes, I know it’s only February. And yes, I also know that us midwesterners should be used to these dramatic weather changes, but it’s still annoying and I’m still going to whine about it.

Guys, it was 65 degrees 2 days ago and now we are expecting yet another winter storm.

One thing I do love about snow days is that Elle and I can get into the kitchen and whip up simple desserts that she can make almost entirely be herself.

Easy recipes like peanut butter pretzel bars, rice krispie treats and these raspberry bars are amongst some of our snow day favorites.

It’s no secret how much I love a baking mix shortcut. Whether it’s using cookie mix in pumpkin cheesecake bars or homemade Bisquick mix in Make-Ahead Banana Coffee Cake, I don’t mind taking a little baking shortcut every now and then.

And as much as I love making recipes like Berry Crumble Bars, Apple Pie Bars, and Cranberry Crumb Bars from scratch, I knew there had to be a quick-and-easy way to make crumble bars.

Enter: Raspberry Bars.

These simple bars use just a handful of pantry staples to make a crumble bar that comes together in minutes:

  • Yellow cake mix
  • Quick oats
  • Light brown sugar
  • Unsalted butter
  • Pecans
  • Raspberry jam

See? I bet you have several of those ingredients on hand already, if not all of them! 

Give yourself about 30 minutes and you’ll have a pan of delicious Raspberry Bars to share with friends and neighbors or take to that last-minute potluck you forgot about.

To make these raspberry crumble bars, grab a large bowl and mix together the yellow cake mix, oats, brown sugar, and melted butter. Mix everything together until the mixture resembles coarse crumbs and you don’t have any dry mix left.

Add just over half of the crumb mixture into a greased 13×9-inch pan and press it evenly to cover the bottom of the pan.

If you’re adding pecans to your crumble topping, stir the pecans into the remaining oat mixture now.

In a small bowl, whisk together the raspberry jam and water to make your raspberry filling. Spread this over the crust, then sprinkle the remaining oat mixture over the top of the jam layer.

Bake the bars for 18-23 minutes, or until the topping is golden brown. Cool completely before cutting into bars and serving.

The fun part about this recipe is that you can change it up in a few different ways!

  • Don’t love raspberries? Try a different flavor of jam! Swap out the raspberry preserves for blackberry jam or even strawberry or blueberry preserves.
  • Try a different cake mix flavor. If you don’t have a yellow cake mix on hand, grab a butter cake mix or even a lemon cake mix instead.
  • Leave out the pecans or swap them out! Feel free to leave out the nuts altogether, or use finely chopped walnuts or even pistachios in place of the pecans.

If you don’t have any quick oats on hand, you can substitute rolled oats (also known as old-fashioned oats) by pulsing them in a food processor a few times. Be sure to measure them out for the recipe after they take a spin in the food processor, not before!

Store the bars in an airtight container on the counter for up to 3 days.

If you’d like to freeze these Raspberry Bars, place them in an airtight, freezer-safe container. If you need to layer the bars, place pieces of parchment paper between them. 

Freeze the bars for up to 1 month. Let the bars thaw at room temperature before serving, or microwave for 30 seconds to warm them before digging in!

These Raspberry Bars are as easy as can be to make! This recipe uses cake mix, oats, and brown sugar to create a delicious crumble topping over the top of a raspberry jam filling. 


  • 1 box yellow cake mix 15.25 ounces
  • 2 ½ cups quick-cooking oats
  • cup packed light brown sugar
  • ¾ cup unsalted butter melted
  • ¼ cup pecan chips optional
  • 1 cup raspberry jam
  • 1 tablespoon water


  • Preheat the oven to 375°F. Grease a 9″×13″ inch pan. Set aside.
  • In a large bowl, mix together cake mix, oats, brown sugar, and melted butter so that it makes nice clumps and there is no dry mix left. Press just over 1/2 of the oat mixture evenly into the bottom of the prepared baking pan. Stir the pecans into the remaining oat mixture.
  • In a separate bowl, mix jam with water, and spread over the crust. Sprinkle the remaining oat mixture evenly over the top.
  • Bake in the preheated oven for 18 to 23 minutes, or until the top is lightly browned. Cool before cutting into bars.

    I rated this a four, because it probably could have used less rolled oats , salted butter would’ve ramped up the flavor & maybe a bit more fruit filling.

  2. Renee says:

    I make these bars with blackberry jam and omit the nuts. They always are a fav and the first dessert gone!

    1. Jamie says:

      I love them with blackberry jam too! Nuts are definitely optional. :)

    Having such a great time with this recipe! I just found it a few weeks ago and the third batch is in the oven right now! The first time I followed the recipe almost exactly – yellow cake mix with raspberry jam – I just sprinkled a cup of mini choco chips on the jam before the topping. Huge hit with choco-loving husband and my young great-nephews! The next version was a chocolate cake mix with strawberry jelly – another win. Then, my niece used apple butter with a spice cake mix. My newest rendition is a lemon cake mix with quince jelly. I am sure it will be great too! I try to bake from scratch but too often time is at a premium. That’s when cake mixes can be magic! This will now be my go-to recipe when I need a quick pan of great cookies! Thanks!

    So I tried this with a gluten-free cake mix (my son and I have celiac disease) and other than needing to add more butter/margarine than is called for, it worked just fine. Anyone making this option would also need to use gluten-free oats. These were great, my family of eight vacuumed them right up! Thank you!

    I made these bars couple of times , they are fabulous , thank you so much I’m a big fan , unfortunately all I have today is a vanilla cake mix
    box , will it gave me the same result instead of the yellow cake mix ???

    1. Jamie says:

      I think that will be completely fine. Enjoy and thanks so much for stopping by!

    Back in 1959 the neighbor's man of the house insisted that they have cake every week, and "No box cake will ever be in MY house!" He bragged on and on about his wife's delicious cakes.

    Of course, they threw the boxes away at our house so he didn't know. Heh!

    Ironic! I was looking for a way to semi-homemake a (really old-fashion) Blackberry Jam cake and was confused on which flavor CAKE MIX I should try and there you were with your jam bars from cake mix. I will try the yellow mix first. Thanks so much. (This was my first time reading a blog)
