Easy Raspberry Bars with Oatmeal Crumble Topping

I love raspberries in all ways. From crisps and crumbles to bread to scones to drinks, I’m a fan. And if there’s a crumble or streusel topping, the happier I am!

It’s even better when the crust and crumble topping are one and the same, so there’s one less step and one less bowl to wash. Which is exactly the case with these supremely easy, no-mixer raspberry oatmeal bars.

I adapted my Blueberry Oatmeal Crumble Bars, which are a reader favorite, and incorporated raspberry preserves. You don’t need fresh raspberries for this fruit bar recipe, so you can make the bars year round.

The raspberry bars are soft and slightly chewy, and the hearty oats are a perfect contrast to the sweet jam. The big, buttery, oatmeal crumbles are irresistible.

These dessert bars aren’t overly sweet, and the raspberry flavor shines nicely making them an easy grab-and-go breakfast, snack, or a healthy dessert. They also happen to be egg-free, which may come in handy for some people.

How to Make Raspberry Bars 

To a large bowl, whisk together melted butter, two types of sugar, and vanilla extract. Then, carefully stir in flour, oats, and a pinch of salt, and stir to combine. At this point, you’ll want to set aside one cup of the mixture — you’ll use this later as the oatmeal crumble topping! 

Transfer the remaining crumble mixture to a greased 8-inch square pan. Use your fingers or a spatula to pack down the mixture to form a crust. 

Once the crust has been packed down, evenly spread the raspberry preserves over it. Make sure the preserves completely cover the crust! 

Finally, sprinkle the preserves with the reserved crumble topping. Again, make sure to evenly distribute the mixture so that every bite of these raspberry bars will have all the layers. 

Bake the raspberry oatmeal bars until the edges are set and the center is lightly golden brown. Place pan on a wire rack and allow bars to cool for at least 2 hours before slicing and serving (the wait is worth it, trust me!). 

How to Freeze Raspberry Bars

These fruit bars freeze and reheat beautifully. To freeze these bars, cut them into wedges once fully cooled. Then, place them on a baking tray and set that in the freezer. After 90 minutes or so, the bars should be firm enough to stack in a freezer baggie or freezer-safe container. 

When you’re ready to enjoy the frozen raspberry bars, simply set them out on the counter to thaw to room temperature. These bars are delicious as is, but a small scoop of vanilla ice cream would be a welcome addition!

Raspberry Bars with Oatmeal Crumble Topping

These easy Raspberry Bars are made with a delicious oatmeal crumble topping. They require less than 10 minutes of hands-on prep and everyone loves these!

Yield: 8 bars
Prep Time 5 minutes
Cook Time 30 minutes
Cooling Time 1 hour 30 minutes
Total Time 2 hours 5 minutes

Ingredients

  • 1/2 cup (1 stick) unsalted butter, melted
  • 1/2 cup granulated sugar
  • 1/4 cup light brown sugar, packed
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 3/4 cup old-fashioned whole-rolled oats (don’t use quick cook or instant, they’re finer and behave like flour and will make mixture too dry)
  • pinch salt, optional and to taste
  • about 12 ounces raspberry preserves (with or without seeds)

Instructions

  1. Preheat oven to 350F. Line an 8-inch square pan with aluminum foil and spray with cooking spray; set aside.
  2. To a large, microwave-safe bowl add the butter and heat on high power to melt, about 1 minute.
  3. Add the sugars, vanilla, and whisk to combine.
  4. Add the flour, oats, optional salt, and stir to combine. Mixture will have some larger, well-formed crumble pieces as well as some sandier, dryer bits.
  5. Set 1 heaping cup mixture aside to be sprinkled on later as crumble topping.
  6. Transfer remaining mixture to prepared pan, and using a spatula or your fingers, hard-pack the mixture to create an even, smooth, flat crust.
  7. Evenly spread the raspberry preserves over the crust making sure there’s complete coverage. Preserves should be about 1/8-inch to 1/4-inch thick.
  8. Evenly sprinkle with the reserved heaping 1 cup crumble topping mixture. Before sprinkling, I squeeze the mixture in my palm to encourage bigger crumble pieces to form.
  9. Bake for about 30 to 32 minutes, or until edges are set and center has just set and is lightly golden browned. Place pan on a wire rack and allow bars to cool for at least 2 hours before slicing and serving.

  1. they look yummy and nice, don’t think it will last a week

  2. I am a huge fan of buttery crumbs, especially raspberry bar ones! I can never get enough crumble. Happy new year!

  3. A crumble or streusel is one of the greatest toppings ever! These kind of remind me of jam filled thumbprint cookies, amped up with oatmeal and in bar form. They look delicious and have a festive, bright vibe going on!

  4. oooh this sounds incredible! i will have to try it soon! thanks for sharing! :)

  5. Delicious!! Want to make the raspberry oatmeal crumble bars

    Kisses from http://poshnessary.com

  6. How did you know this is EXACTLY what I was craving right now? ;) Love the extra crumbly topping on these bars!

  7. I didn’t think you’d be able to come up with something that would tempt me, after all the Christmas gluttony–once again, you have proven me wrong.  I think I even have raspberry preserves on hand …

    • Hello, I found your recipe for “The Best Raspberry Bread” and made it several times already for some older women that cannot bake anymore and they asked me if I would put a streusel topping on it before baking? Do you have any comments or suggestions for me???

      • I haven’t added a streusel to that bread but you could easily cut a few tablespoons of butter into brown sugar and flour and crumble it on top and maybe that would work for you. Haven’t personally tried it though. Glad that the recipe is a hit with the ladies!

  8. Oh my gosh, these bars are beautiful! They’re making my mouth water like crazy! I know what I’ll be baking this weekend! ;)

  9. I have frozen raspberries.How do I make ‘Raspberry Preserve”?

  10. Great recipe, but in all seriousness, do you even eat what you make?

    You’re awfully thin.

    • Yes I eat what I make, but not the entire batch of everything I made! Who could eat a batch of cookies, a whole cake, a pan of brownies, a 4-serving chicken dinner, etc. every week without help! I have family, friends, teachers, coaches, etc. who I share with.

  11. I love raspberries too, they have incredible flavor that only gets better with cooking and baking. These bars look so delicious, I can almost smell them. Happy New Year, Averie! :)

  12. Is Raspberry ‘preserve’ the same as raspberry jam or more like a pie filling with cornstarch as a thickener?
    When I googled raspberry preserve I got a recipe for jam with lots of sugar & certo used as a thickener.

  13. I know just what you mean about crumble toppings.  Having anything with the word “crumble” in it puts me in an instantly good mood.  These look so good!

  14. I’m in love with this, as I am all your crumble bars. I think crumble should be a requirement for ALL desserts!

  15. Happy New Year! Those look amazing!

  16. These bars look amazing! I wish I had all the ingredients to make them right now, and eat them for breakfast!

  17. Can’t wait to make the Rasberry Oat bars… I will use my favorite jam “Favorit”Swiss Raspberry Preserves, 12.3 oz. I get the best deal from Walmart. It’s from Swizerland & the flavor is amazing. Normally I purchase Costco’s Kirkland Oraganic Raspberry Jam, but haven’t seen any this Winter. You won’t be sorry with the Favorit Brand above.

  18. These bars are amazing! I’ve made them twice in the last week and am so in love with them. I’m sharing them on my site tomorrow.  

  19. I made this to bring into work and they were amazing!! I think they were gone within an hour….definitely a recipe to hold on to and make again! And soooooo easy to make! I had these whipped up and in the oven in 5-minutes. Another wonderful recipe from Averie! Thank you for all the amazing recipes you share on your blog!!! ?

  20. Hi Averie, 

    Have you ever tried black cherry preserves with mini chocolate chips in your oatmeal crumble bars?  If not, I highly recommend it! 

  21. The raspberry oatmeal crumble bars look delicious! i can’t wait to try them out! i was wondering if you had an idea how many calories or how fattening they are?? x 

  22. Thank you so much for this easy and delicious recipe! I brought them to work and they were gone in minutes. I’m going to double the recipe next time for sure, so I can have some for myself ;)

  23. Thankyou Averie. We love your quick and easy raspberry crumble oatmeal bars. Favourite new recipe! I make the jammy layer a bit thinner (i.e. less jam) and scatter some frozen raspberries on it before the crumble goes on top. Feels a bit healthier. I’ve doubled the recipe today.

  24. These sound so amazing! Great for breakfast!

  25. So easy to make, and delicious!
