These Raspberry Streusel Bars start with a buttery shortbread crust, get piled high with a jammy raspberry filling, and finish under a thick layer of brown sugar streusel.
One dough does double duty as both the crust and the crumb topping, so you get all the texture without extra dishes to wash.
They are the kind of dessert bar that disappears within a day at any potluck or bake sale. Sweet, a little tart, buttery, and crumbly all at once.

I first made a version of these bars for a friend’s baby shower a few summers back, and I have been tweaking the ratios ever since.
The trick is using the same dough for the base and the topping, which keeps the flavors consistent from bottom to top.
They taste similar in spirit to my Peach Crumb Bars, just swapped out for bright, juicy raspberries.

Ingredients
Most of what you need for these bars is likely already in your pantry.
The star ingredients are the raspberry preserves and fresh raspberries, which give the filling its bright, jammy flavor.
- All-purpose flour
- Granulated sugar
- Salt
- Unsalted butter, softened
- Old-fashioned rolled oats
- Light brown sugar
- Chopped pecans
- Seedless raspberry preserves
- Fresh raspberries
- Fresh lemon juice
- Vanilla extract
- Powdered sugar (for the glaze)
- Milk (for the glaze)
I always reach for real, softened butter here rather than a substitute. It is what gives this crust its classic shortbread cookies texture.

Recommended Products for This Recipe
These are a few products I personally rely on when I make raspberry streusel bars, based on what has genuinely made the process easier or the results better.
1. Bonne Maman Raspberry Preserves
A good quality preserve makes a real difference in the filling since it is doing most of the flavor work.
Bonne Maman has a true fruit forward flavor without tasting artificial, and it spreads smoothly over the hot crust.
2. USA Pan Nonstick 9×13 Baking Pan
An even-heating, heavy gauge pan helps the crust bake through without scorched edges.
I have used this pan for years and the nonstick coating means the bars release cleanly every time.
3. OXO Good Grips Bench Scraper
This makes cutting the finished bars into clean, even squares so much easier than a regular knife.
It is also handy for pressing the crust firmly and evenly into the pan.
4. KitchenAid Stand Mixer
Mixing the dough by hand works, but a stand mixer makes quick work of creaming the butter and blending the flour without overworking it.
It is one of those tools that earns its counter space many times over.
I picked up my pecans for this batch of bars while restocking pantry staples, since they show up in so many of my baked goods, chopped pecans are always on my grocery list.
Step-by-Step Instructions: How to Make Raspberry Streusel Bars
1. Prep the pan and oven
- Preheat your oven to 375°F (190°C).
- Line your 9×13-inch baking pan with foil or parchment paper, leaving a two inch overhang on the sides so you can lift the bars out later.
- Lightly grease the foil or parchment with butter or nonstick spray.
2. Make the shortbread dough
- In the bowl of a stand mixer, or a large bowl if mixing by hand, combine the flour, granulated sugar, and salt.
- Mix on low speed for a few seconds just to combine.
- With the mixer running, add the softened butter one piece at a time, mixing until the mixture resembles damp sand.
3. Set aside dough for the streusel
- Measure out about one and a quarter cups of the crumbly dough mixture and transfer it to a separate bowl.
- Set this reserved portion aside. It will become your streusel topping later.
4. Press and bake the crust
- Press the remaining dough firmly and evenly into the bottom of the prepared pan.
- Use the bottom of a measuring cup or your bench scraper to smooth it into an even layer.
- Bake for 14 to 16 minutes, until the edges just begin to turn golden brown.
- Remove from the oven but keep it on hand. The crust should be hot when the filling goes on.
5. Build the streusel topping
- While the crust bakes, add the brown sugar, rolled oats, and chopped pecans to the reserved dough mixture.
- Toss everything together with a fork until evenly distributed.
- Pinch the mixture between your fingers to form small clumps, then set aside.
6. Mix the raspberry filling
- In a small bowl, combine the raspberry preserves, fresh raspberries, lemon juice, and vanilla extract.
- Mash gently with a fork, leaving some raspberry pieces intact for texture.
7. Assemble the bars
- Spread the raspberry filling evenly over the hot crust using an offset spatula.
- Sprinkle the streusel topping evenly over the filling. Do not press it down, it should sit loosely on top.
8. Bake until golden
- Return the pan to the oven and bake for 22 to 25 minutes, until the filling is bubbling at the edges and the streusel is deep golden brown.
- Rotate the pan halfway through baking for even color.
9. Cool completely
- Transfer the pan to a wire cooling rack and let the bars cool completely, about two hours.
- This step matters. Cutting them too early will cause the filling to ooze and the bars to fall apart.
10. Glaze, slice, and serve
- If using the glaze, whisk together the powdered sugar and milk until smooth, then drizzle it over the cooled bars.
- Use the foil overhang to lift the bars out of the pan and onto a cutting board.
- Slice into squares with a sharp or serrated knife and serve.
Tips for The Best Raspberry Streusel Bars
A few small details make a noticeable difference in how these bars turn out.
Most of the common issues come down to temperature and timing rather than the ingredients themselves.
- Make sure your butter is truly softened, not melted, for the best crumbly texture
- Do not press the streusel topping into the filling, it should stay loose and crumbly
- Let the bars cool fully before slicing, even if that means waiting a couple of hours
- Use a serrated knife for the cleanest cuts through the streusel layer
- If your raspberries are very tart, add a touch more sugar to balance the filling
The same streusel technique shows up in my Cinnamon Streusel Bread, so if you love this crumbly topping, that one is worth a try too.
Serving Suggestions
These bars are rich enough to stand on their own, but a few pairings take them from good to memorable.
I like serving them slightly chilled on warm days, or just barely warm with a scoop of something cold on top.
- A scoop of vanilla ice cream melting over a warm bar
- A dollop of lightly sweetened whipped cream
- Alongside a cup of coffee or tea for an afternoon treat
- Cut into smaller squares for a dessert platter at parties
- Paired with fresh berries for extra color on the plate
For a dessert table, I love setting these next to a slice of Blueberry Crumble so guests get a mix of textures and fruit flavors.
Variations of Raspberry Streusel Bars
Once you have the base method down, this recipe is easy to adapt.
The dough, filling, and topping can all be swapped around depending on what you have on hand or what you are craving.
- Swap raspberries for blackberries, blueberries, or a mix of berries
- Use walnuts or almonds instead of pecans in the streusel
- Add a half teaspoon of cinnamon to the streusel for a warmer flavor
- Stir a tablespoon of cornstarch into the filling if you prefer a thicker, less runny texture
- Leave off the glaze for a simpler, less sweet finish

Storage and Reheating
These bars hold up well for several days when stored properly, though they are always best on the day they are baked. The crust and streusel will soften slightly as they sit.
- Store in an airtight container at room temperature for up to 2 days
- Refrigerate for up to 5 days for longer freshness
- Freeze whole, uncut bars for up to 1 month, wrapped tightly in foil
- Thaw frozen bars at room temperature for about 4 hours before slicing
- Warm briefly in the microwave if you prefer them slightly warm before serving
These bars remind me a bit of the texture in my Blackberry Lemon Poppy Seed Muffins, another fruit-forward bake that keeps well over a few days.
Nutritional Facts

Health Benefits of Key Ingredients
While this is very much a dessert, a few of the ingredients bring some genuine nutritional value along with their flavor.
Raspberries in particular are one of the more nutrient-dense berries available.
- Raspberries are high in fiber and packed with antioxidants
- Oats provide additional fiber and help slow sugar absorption
- Pecans contribute healthy unsaturated fats and a bit of protein
- Lemon juice adds vitamin C and brightens the overall flavor
I lean on raspberries in a lot of my baking for this reason, they show up often in fruit desserts like my Cherry Crisp too.
FAQs About Raspberry Streusel Bars
1. Can I use frozen raspberries instead of fresh?
Yes, frozen raspberries work well in this recipe. Just thaw them first and gently pat them dry with a paper towel so the extra moisture does not make the filling too watery.
2. Why did my streusel topping turn out too soft?
This usually happens if the butter was too warm or overmixed into the crumb mixture.
Try chilling the streusel mixture in the fridge for about 15 minutes before sprinkling it over the filling.
3. Can I make these bars ahead of time?
Absolutely, these bars actually store well for a few days.
Bake them a day in advance, store covered at room temperature, and add the glaze right before serving for the freshest look.
4. What can I use instead of raspberry preserves?
Any seedless berry preserve works as a substitute, such as blackberry, strawberry, or mixed berry.
Just make sure it is thick enough to hold its shape once spread over the crust.
5. Why do I need to spread the filling over a hot crust?
Spreading the filling while the crust is still warm helps it settle into an even layer and helps the layers bond together as they bake, so you get clean slices rather than a filling that slides off the crust.
If you have more questions about swapping ingredients, you might find answers in my No Bake Strawberry Lemon Swirl Tart post, which covers similar fruit filling techniques.
