Raspberry Streusel Bars: Scrumptious berry bars with a melt in your mouth oatmeal crumb topping made with fresh or frozen berries!
With a sweet oatmeal crust, a layer of fresh berries and jam plus a crumble topping, how could you resist these divine Raspberry Bars?
Why You Should Make Raspberry Crumble Bars
I made these jewel-toned beauties to share with my girlfriends at our “knitting” group. They knit; I chat and bring goodies. My friends are much better at giving me an honest critique…at home, the comments range from “good” to “eh” to “terrific.”
- This is an easy dessert to showcase fresh raspberries when there’s no time to make a more time-consuming recipe like a raspberry pie.
- These can be served as finger good, so perfect for summer barbecues, picnics, or any casual gatherings.
- Oatmeal and fresh raspberries provide a wee bit of fiber and Vitamin C. This may be a bit of a stretch, but healthier than chocolate mousse!
Frequently Asked Questions
They can be kept at room temperature for 1-2 days. After that, it’s best to refrigerate to prevent them from spoiling.
Keep them covered with foil or in an airtight container at room temperature for the first day or so. They are best eaten fresh. After that, store in the refrigerator or freeze for up to 3 months.
Melted (or even softened) butter is mixed with the dry ingredients until crumbly. Then sprinkle over the berry filling using your fingers to pinch some of the crumbs into larger crumbs.
With this recipe, the crumb topping is baked along with the filling. Bake until the filling is bubbly and the crumble is lightly browned.
Yes, but you may want to add a little more flour to the mix to account for the juiciness of frozen berries. Defrost the berries before using them.
I love making raspberry pie, peach raspberry pie, raspberry crisp and an array of different raspberry bars. Raspberries are also delicious in parfaits, fruit salads, and more.
How to Make Raspberry Oatmeal Bars
My picky hubby only likes his oatmeal for breakfast, cooked to a nearly inedible consistency and loaded with brown sugar. But he’s not a fan of oatmeal in any kind of dessert. Sigh. I keep on trying!
- Preheat your oven and line the baking pan with non-stick foil
- Mix together the crumb topping.
- Use part of the crumbs for the crust and reserve part for the crumble.
- Press part of the crumbs onto the bottom of the pan for the crust and bake.
- Cool the crust a bit, spread the mixture of jam, berries, lemon juice, and zest on top. Crumble the reserved topping over the berry filling.
- Bake, cool, cut into bars, and enjoy!
The hubby does not know what he’s missing as these raspberry streusel bars were spectacular. The crew made these disappear so I didn’t have the task of eating them ALL myself (what a tortuous job that would have been!).
The original recipe called for fresh blueberries with raspberry jam, but I swapped out the blueberries for raspberries. I think any combination of complementary berries and jams would work well. Note that these bars are best on the day they’re baked, but they’re still pretty irresistible after that.
Tips for Making Raspberry Squares
- Choose red, plump raspberries without signs of deterioration.
- If you’d like thicker bars, use an 8-inch square pan instead of a 9-inch. Your bars may take a few more minutes to bake in the smaller pan.
- I like to line my baking pans with non-stick foil. Besides preventing the bars from sticking to the pan, the foil also doubles as a sling to help lift the cool bars out of the pan and transferring them to a cutting board.
- Bake the crust first, let cool a bit, add the toppings, and finish baking.
- As mentioned in the recipe, use fresh lemons for the juice and the zest. One large lemon gave me enough for both.
- For a more elegant dessert, serve one of these raspberry bars in a bowl next to a scoop of vanilla ice cream with a few fresh raspberries to garnish!
- Oatmeal – Classic oats were called for in the original recipe but quick oats will do in a pinch
- All-purpose Flour
- Brown Sugar
- Butter – Melted, although softened was used in the original recipe. I always use salted butter in my recipes, unless otherwise noted.
- Fresh or Frozen Raspberries – Defrost frozen raspberries. If they’re really juicy, consider adding some extra flour
- Lemon Peel – I used a fine zest from one whole lemon. Make sure to zest before you squeeze the lemon.
- Fresh Lemon Juice – Always use fresh lemon juice, never bottled, for the best flavor.
