How to make Raspberry Oat Crumble Bars (Mazurka-Style Jam Squares)
Making Raspberry Oat Crumble Bars is an enjoyable and straightforward process that requires minimal preparation. You begin by gathering the essential ingredients, which include flour, light brown sugar, rolled oats, chopped nuts, finely shredded coconut, butter, and, of course, raspberry preserves. The buttery oatmeal crust serves as the perfect base for the rich layer of preserves, and retaining some of the crumble mixture for the topping adds an extra crunch.
To create the base, you start by mixing the dry ingredients in a large bowl until they are evenly combined. Once blended, the melted butter is added, allowing the mixture to come together into a crumbly dough. By reserving a portion of this crumbly mixture, you ensure that the bars have a delightful topping. After pressing the base firmly into the pan, the sweet raspberry filling is spread evenly, with the reserved crumbs sprinkled on top before baking. The final baking moment allows the flavors to meld beautifully while the edges turn a lovely golden brown.
The result is a tray full of delicious bars that can easily be lifted out and sliced into perfect squares. These bars hold their shape well, making them easy to transport to gatherings or share with family and friends. Their inviting aroma fills the kitchen while they bake, making it hard to resist sneaking a piece right from the pan. These Raspberry Oat Crumble Bars also lend themselves well to customization and personal touches, allowing each baker to make them uniquely theirs.
Ingredients
- 160 g (1¼ cups) all-purpose flour
- 200 g (1 cup) light brown sugar, packed
- 75 g (¾ cup) rolled oats
- 73 g (⅔ cup) chopped walnuts or pecans
- 45 g (½ cup) finely shredded unsweetened coconut
- ¾ teaspoon fine sea salt
- 113 g (8 tablespoons) unsalted butter, melted
- 300 g (1 cup) raspberry preserves
Directions
- Heat the oven to 325°F (about 160°C) and prepare an 8×8-inch pan by greasing it lightly and lining it with parchment paper that overhangs the sides for easy removal.

How to store Raspberry Oat Crumble Bars (Mazurka-Style Jam Squares)
To ensure that your Raspberry Oat Crumble Bars remain fresh and delicious, proper storage is essential. Once the bars have completely cooled, transfer them to an airtight container. If you’re concerned about them sticking together, you can place layers of parchment paper between the bars. This method helps maintain their texture and makes them easier to take out individually without crumbling.
Stored this way, the bars should last for several days at room temperature. If you want to keep them for an extended period, consider refrigerating them, where they can maintain their freshness for up to a week. For even longer storage, these bars can be frozen. Wrap them securely in foil or plastic wrap, and then place them in a freezer-safe container. When you’re ready to enjoy, simply thaw them at room temperature or warm them up briefly in the oven for a freshly-baked taste.
Tips to make Raspberry Oat Crumble Bars (Mazurka-Style Jam Squares)
Creating the ideal Raspberry Oat Crumble Bars is effortless with a few helpful tips. First, aim to use high-quality raspberry preserves; the flavor of your filling is paramount. Opt for all-natural varieties without added pectin or excess sugars if possible, as this will enhance the overall taste of the bars. Additionally, feel free to experiment with different nuts, such as almonds or hazelnuts, based on personal preference or what you have available in your pantry.
Keep an eye on the baking time, as ovens can vary. If you’re unsure, check the bars halfway through the suggested baking time. The perfect bars should have a beautifully golden top, but they will continue to firm up slightly as they cool. For an extra layer of flavor, consider adding a pinch of cinnamon or nutmeg to the crumble mixture, which adds warmth and richness without overwhelming the raspberry flavor. Finally, the bars are best enjoyed after allowing them to cool fully, as this allows the filling to set properly, making them easier to slice.
Variation
No major variations, but you can adjust seasonings to taste.
