Delicious Raspberry Oatmeal Cookie Bars are a sweet and tangy treat with layers of buttery oat crumble and vibrant raspberry jam.
These bars feature a chewy, golden base made from rolled oats and brown sugar, topped with a luscious layer of raspberry filling and finished with a crumbly oat topping.
Perfect for dessert, snacking, or even breakfast on the go, they strike the perfect balance between fruity freshness and wholesome texture.
Easy to make and crowd-pleasing, they’re ideal for picnics, lunchboxes, or holiday trays. Enjoy them warm or chilled, with a cup of tea or a scoop of vanilla ice cream.
In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar together using an electric mixer (or by hand if you prefer). Cream them until the mixture is light and fluffy, which should take about 2–3 minutes.
Let the bars cool in the pan for at least 30–45 minutes before attempting to slice. For best results, chill them in the fridge for an hour. Once cooled, lift them out using the parchment paper and cut into bars or squares.* Percent Daily Values are based on a 2,000 calorie diet.

1. Use Fresh or Quality Preserves:
For a bright, tangy flavor, use high-quality raspberry jam or preserves. Avoid overly sweet or gelatinous options. If fresh raspberries are in season, mash a few and stir them into the jam to add texture and natural tartness.
2. Balance the Crust-to-Filling Ratio:
Raspberry oatmeal bars have two main components: a buttery oat crust and a fruity filling. Save about ⅓ of the oat mixture for the topping. This ensures a firm base and a crisp, crumbly top without overpowering the raspberry layer.
3. Don’t Overmix the Dough:
Overworking the dough can make the crust tough instead of tender. Combine the oat mixture just until the butter is incorporated and the mixture is crumbly. A food processor can help, but mixing by hand gives more control.
4. Use Cold Butter for Crumble Texture:
Cold, cubed butter helps create that perfect crumbly texture in the oat crust and topping. If the butter is too soft, the mixture may become pasty and dense rather than light and crisp.
5. Line Your Pan for Easy Removal:
Line your baking dish with parchment paper, letting it hang over the edges. This makes lifting the cooled bars out of the pan effortless and helps cut cleaner slices. It also prevents sticking and makes cleanup easier.
6. Let Them Cool Completely Before Cutting:
Warm bars can fall apart. For clean, even bars, allow them to cool in the pan completely—ideally for an hour. Refrigerating for 15–30 minutes before slicing can make them firmer and easier to cut.
7. Add a Flavor Boost:
Enhance your bars with a touch of almond extract or lemon zest in the crust to complement the raspberries. A small sprinkle of chopped nuts like almonds or pecans in the topping can also add a satisfying crunch.
1. Slice Into Bite-Sized Squares for Parties:
Cut the bars into small 1x1-inch squares and arrange them on a platter for finger-food-friendly treats. Dust lightly with powdered sugar for a bakery-style presentation.
2. Serve Warm with Ice Cream:
For a decadent dessert, gently warm a square in the microwave and top it with a scoop of vanilla bean or raspberry ripple ice cream. Drizzle with melted white chocolate for an elevated touch.
3. Add to a Brunch Spread:
These bars are a welcome addition to brunch or tea-time menus. Pair with fresh berries, yogurt parfaits, and herbal teas or mimosas.
4. Pack for Lunchboxes or Picnics:
Raspberry oatmeal cookie bars travel well and hold their shape, making them perfect for packed lunches, potlucks, or picnic baskets. Wrap individual portions in wax paper or foil for easy grab-and-go snacks.
5. Store and Freeze Wisely:
Store in an airtight container at room temperature for up to 3 days, or refrigerate for a week. To freeze, layer bars between parchment in a freezer-safe container for up to 3 months. Thaw at room temperature before serving.
These bars are perfect on their own but can be taken to another level with a scoop of vanilla ice cream, a dollop of whipped cream, or even a drizzle of melted white chocolate. Serve them warm or chilled.
