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

  2. 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.

    • Thanks for trying the recipe and I’m glad it came out great for you! There’s this one too with blueberries in case you haven’t seen it! https://www.averiecooks.com/2015/02/blueberry-oatmeal-crumble-bars.html

      • It’s definitely an extremely versatile recipe and I’m not sure that it is physically possible to mess it up.I’ve tried it many ways, including:- As written- Substituting out different jams/preserves/fruits- Plopping chopped (uncooked) fresh fruit on the base instead of preserves for a more gooey bar- Making my own jam, no pectin needed (Add your fruit plus –per pound of fruit– about 2 Tablespoons of lemon juice and 1/4 to 1/2 cup of sugar to a saucepan. Sugar usage should depend on the tartness of your fruit. Simmer it all together on low to medium heat, stirring occasionally, until it thickens enough to coat the back of a spoon. Allow to cool before adding to the bar base.)My most recent batch of these involved making my own jam out of cherries and strawberries. The bars got quite a few compliments at work! Thank you so much for sharing this amazing recipe with us! It’s still one of my favorite treats to make.

      • Thanks for the 5 star review and glad you love this recipe and have done lots of experimenting with it! I agree, pretty much impossible to mess up yet you’d be surprised sometimes :)

  3. awesome post i like it :)

  4. I need these with blueberry jam as the original calls for. But I used only about half the jam, half the sugar, and I threw in a couple tablespoons of flaxseed. I wouldn’t go so far as to call these “healthy”, but not nearly as sugary. They’re great with a cup of tea or coffee. I’d bet a scoop of vanilla ice cream would make them outright decadent. Next time I’ll try making them with almond meal and apricot jam instead. Yummy!

  5. They’re in the oven right now!! I made them with strawberry jam and trader joe’s gluten free flour blend. I’ve never substituted 1:1 GF flour for regular flour, so we’ll see how it turns out. It looked pretty normal while it was raw (and the crumble batter tasted delicious) so I have high hopes!

  6. Love this! I use fresh raspberries with sugar and it works perfectly. ?

  7. I had these at a potluck in my school. A colleague had made these and we were all fighting over it. Im planning to make as a favor for a religious festival since they don’t contain eggs. If I have to give it to guests on Saturday, how many days in advance can I make them to ensure that they are fresh. Also, do I need to refrigerate the after make them (I’m thinking no…since the bitter might solidify, but you’d know best). Thanks in advance.

  8. Very easy to make with excellent instructions will definitely recommend to my friends.

  9. The blueberry oatmeal bars use fresh berries but this once calls for preserves. Why is that?

    • It’s just the way I chose to make this one honestly to save money since fresh raspberries are usually very expensive and hard to find frozen whereas you can easily find inexpensive frozen blueberries.

  10. Made these this morning using blueberry jam as that is what I had on hand. I did have to swap coconut oil for the butter as I currently on a low iodine diet. I can’t wait to make these using butter as soon as I am off this retched diet. These are delicious and very easy to make with so many possible flavor combinations. I

  11. If frozen how would recommend using these? Should I microwave it until thawed or should I allow them to thaw on their own? Having a baby soon and these sound delicious to have made ahead of time for after baby comes home.

  12. The crust of these bars is great, but with the recommended amount of preserves, it is TOO sweet! Will make again, but with half the amount of jam.

  13. Hello! Could I use fresh fruit instead of preserves?

  14. I’ve made this recipe a few times. It’s easy and delicious!

  15. Super easy! Really good!
