Raspberry Oatmeal Crumble Bars

I love raspberries in all ways. From crisps and crumbles to bread to scones to drinks, I’m a fan.

And if there’scrumble or streusel topping, the happier I am.

Raspberry Oatmeal Crumble Bars - Fast, easy, no-mixer bars great for breakfast, snacks, or a healthy dessert!! The big crumbles are irresistible! Fresh raspberries not needed so you can make the bars year round!!

It’s even better when the crust and crumble topping are one in 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 bars.

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

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

The 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 happen to be egg-free which may come in handy for some people.

Raspberry Oatmeal Crumble Bars

I love raspberries in all ways 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 in the same so there’s one less step and one less bowl to wash which is the case with these supremely easy, no-mixer bars. The bars are soft, slightly chewy, and the hearty oats are a perfect contrast to the sweet jam. The big, buttery, oatmeal crumbles are irresistible. The bars aren’t overly sweet and the raspberry flavor shines nicely making them an easy grab-and-go breakfast, snack, or a healthy dessert and they're egg-free.

Yield: one 8x8 pan, 8 generous wedges

Prep Time: 5 minutes

Cook Time: about 30 minutes

Total Time: about 2 1/2 hours, for cooling

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 (I used about two-thirds of one 18-ounce jar with seeds, use seedless preserves if preferred)

Directions:

  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. Bars will keep airtight at room temperature for up to 1 week or in the freezer for up to 6 months.

  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!!! 😊

    • Thanks for trying the recipe and glad it came out great for you! And thanks for the super nice compliments about my recipes and so glad you had these in the oven in 5 minutes flat!

  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! 

  26. My all time favorite. Awesome recipe. Thanks for sharing this.

  27. This recipe is wonderful. A coworker brought this to work as an early-morning breakfast treat for my team and I knew I had to have the recipe! First time making this, I only used preserves for half of the pan. On the other half I wanted to experiment so I did an even split of fresh blueberries and cherries (I didn’t add any extra sugar to the fruit and I didn’t even cook it down into a jam or filling first). My partner was completely in love with the bars, especially the quarter that had the fresh cherries! This is a recipe that I will definitely be using regularly.
