Raspberry Oatmeal Bars Recipe

Description

These Raspberry Oatmeal Bars are easy enough for a quick weekday bake and simple enough for beginner cooks. The buttery oat crust and bright berry layer make the best healthy sweet ideas for brunch and potluck tables.

1 1/2 cups Old fashioned oats
1 cup All purpose flour
3/4 cup Light brown sugar

Instructions

The oats flour brown sugar baking powder and salt are combined until the dry pieces look uneven and sandy. Melted butter and vanilla are stirred in until clumps form and the mixture holds together in rough crumbs.
Most of the oat mixture is pressed into the baking dish and changes from loose crumbs into a compact base. The surface stays naturally uneven with thicker edges and small oat flakes visible across the top.
Raspberry jam lemon juice and fresh raspberries are spread over the crust so the pale oat base becomes streaked with glossy red filling. Some berries stay whole while others break slightly into the jam layer.
The remaining oat mixture is scattered over the raspberry layer and creates a broken crumb topping. Red filling remains visible between the uneven oat patches so the bars bake with a rustic look.
The pale crumble turns golden and the raspberry filling bubbles into thick glossy pockets around the edges. The topping looks crisp in some places and softer in others which makes the bars look homemade.
A single cut bar is moved to a plate and shows the soft raspberry layer between the oat crust and crumbly top. The edges are slightly rough and the filling looks jammy with natural red streaks and oat crumbs scattered on the piece.

Notes

Pro Tips:

Use old fashioned oats instead of quick oats because they give the bars a better chewy crumble texture.
Let the bars cool fully before slicing because warm raspberry filling can spill and break the crust apart.
Keep some crumble loose on top so the raspberry layer bubbles through and gives a pretty rustic finish.
Use good raspberry jam because it forms the main fruit layer and makes the flavor brighter.

Storage: Store Raspberry Oatmeal Bars in an airtight container once they are completely cooled. Keep them at room temperature for up to 2 days if your kitchen is cool and dry. For longer storage place them in the refrigerator for up to 5 days with parchment between layers. Freeze sliced bars for up to 2 months and thaw them in the refrigerator before serving.
