What do you need to make Oatmeal Plum Bars?
Old-fashioned oats
These oats form the hearty, chewy base of the crust and crumble topping. Their nutty flavor and tender texture add a wholesome, rustic feel. They absorb flavors beautifully, ensuring each bite is rich and moist. Their natural chewiness helps create that melt-in-your-mouth, comforting quality that makes these bars so indulgent
Plums
The star of the dessert, fresh plums provide a juicy, tart, and jammy core. When combined with sugar and cornstarch, they create a luscious, sweet-tart filling that’s both fruity and slightly spiced. Their seasonal, aromatic flavor enhances the rustic charm, making each bite refreshingly tart and beautifully moist
Unsalted butter
Butter gives the crust and crumble topping a rich, buttery flavor that melts in your mouth. It creates a tender, golden crumb that’s irresistibly sweet and indulgent. The butter’s fat content also helps bind the oats and flour into a crumbly, aromatic topping that’s crisp on the edges but tender inside
All-purpose flour
This staple provides structure to the crumble topping, balancing the oats’ texture. It helps create a buttery, crumbly crust that’s crispy and fragrant yet tender. Flour acts as the backbone of the crumbly topping, giving these bars their classic, rustic finish
Ground cinnamon
Adding warmth and aromatic spice, cinnamon elevates the fruity flavor of the plums. It infuses the entire dessert with a comforting, spiced aroma that complements the tartness of the fruit and enhances the overall richness, making each bite more indulgent and seasonal.
Oatmeal Plum Bars step by step
1. Preheat your oven to 180°C (350°F). In a mixing bowl, combine the oats, all-purpose flour, light brown sugar, ground cinnamon, and a pinch of salt. Melt the unsalted butter and pour it into the dry ingredients, mixing until crumbly and evenly coated. Press half of this mixture into the bottom of a greased baking pan to form the crust
2. Slice the plums and remove pits. In a medium bowl, toss the plums with cornstarch and vanilla extract until well coated. Spread the plum mixture evenly over the crust layer, ensuring a juicy, tart filling. Crumble the remaining oat mixture over the top, creating a rustic, crumbly surface
3. Bake in the preheated oven for 40-45 minutes or until the topping is golden brown and the plums are bubbling. Let the bars cool slightly before slicing. For best flavor, serve warm or at room temperature. Enjoy the melty, fruity, sweet-tart goodness that is irresistibly cozy and delicious!
