Raspberry Oatmeal Crumble Bars have a buttery, oat crumble base covered with a layer of raspberry jam, and more oat crumble on top, baked to golden brown. It is a simple-to-make bar that can be enjoyed for breakfast, snack time, or dessert! I also have Raspberry Oatmeal Bars with an almond icing you will love!

Ingredients & Substitutions

Oats: I love the texture of old-fashioned oats, also known as rolled oats. They have a nice, hearty texture that works well in these bars. You could use quick oats, but it may affect the texture.

Butter: Using unsalted butter gives you the most control over salt added to recipes. If using salted butter, you may want to lessen the amount of salt added.

Raspberry Jam: Part of what makes this recipe so simple (but delicious) is the use of raspberry jam. The jam is spread over the bottom layer of the crumble. Raspberry preserves will also work.

Can I Use Other Kinds Of Jam?

Absolutely! These bars are so easy to make, that it would be a tasty experiment to try them with other flavors. Some popular alternatives to raspberry jam could be strawberry, blueberry, blackberry, apricot, or a mixed berry jam, just to name a few.

Do Raspberry Oatmeal Crumble Bars Have To Cool Completely Before Cutting?

Yes. Be sure you give the bars time to cool completely before cutting and serving, about 30-45 minutes. This helps the raspberry oatmeal crumble bars to set for easy and neat cutting. Cutting them too soon may result in the bars falling apart or crumbling.

How To Store Raspberry Oatmeal Crumble Bars

Once cooled completely, raspberry oatmeal crumble bars can be stored at room temperature, in the refrigerator, or the freezer for longer storage. If storing at room temperature, keep them in an airtight container for up to 3-4 days. If refrigerated, they will last up to 5 days or so. Or, freeze the bars in a freezer-safe container for up to 2-3 months.

Raspberry Oatmeal Crumble Bars have a buttery, oat crumble base covered with a layer of raspberry jam, and more oat crumble on top, baked to golden brown. It is a simple-to-make bar that can be enjoyed for breakfast, snack time, or dessert!


  • 1 cup (125 g) all-purpose flour
  • 1 cup (90 g) old-fashioned oats
  • ½ cup (100 g) light brown sugar, packed
  • ¼ teaspoon baking soda
  • teaspoon kosher salt
  • ½ cup (1 stick / 113 g) unsalted butter, melted
  • ¾ cup (240 g) raspberry jam


  • Preheat oven to 350°F. Line an 8×8-inch baking dish with parchment paper. Set aside.
  • To a medium bowl, add flour, oats, brown sugar, baking soda, and salt. Mix well.
  • Pour the melted butter over the dry ingredients. Using a fork or pastry cutter, mix the butter into the dry ingredients until the mixture becomes crumbly and resembles coarse crumbs. Make sure there are no large clumps of dry ingredients remaining.
  • Firmly press ⅔ of the oat mixture into an even layer in the bottom of the prepared pan.
  • Carefully spread the jam on top of the crust. Sprinkle the remaining oat mixture evenly over the raspberry jam layer, covering it completely.
  • Bake for 30-35 minutes, or until the edges are golden brown. Let the bars cool before cutting and serving.

What the Test Kitchen had to say about this recipe:


This is a simple, but delicious bar. It would be perfect with a hot cup of coffee!


So simple, but really enjoyable! I would grab one or two of these to have as a snack. I want to try the recipe with other kinds of jam, too.


This reminds me of a homemade version of a Nutri-grain bar, I like it! Easy to make and quick with the jam center.


I really like this! I find the raspberry very tart and sweet but the oats help balance that! This is very snackable.


These bars are super easy to make! If you're the outdoorsy type, these would be a great option to refuel a little bit after a hike!


This would make a great breakfast bar. Not too sweet and it feels healthy since it's made with old-fashioned oats.
