These olive oil oat jam bars bring the flavors of summer to your winter snacking routine! Just a little sweetness combines with whole grain oats and healthy fats—from Colavita olive oil, of course— to create a perfect bar that's perfect for an afternoon pick-me-up, or a breakfast on the go!
Heat the oven to 350°F.
Grease a 13 x 9 x 2-inch pan with cooking spray or softened butter and line with parchment.
To make the crust and topping, in a large bowl whisk the flour, oats, salt, and sugar.
Add the olive oil, yolk and vanilla and, using a fork, stir until the dough holds together when you squeeze a bit between your fingers.
Remove 2 2/3 cups of dough and place in a medium bowl in the refrigerator. Press the remaining dough firmly and uniformly into the prepared pan.
Evenly spread the jam over the bottom crust.
Sprinkle the refrigerated dough over the jam, rolling it into little balls between your fingers for the ultimate crumble topping, if you so desire.
Bake the bars for about 45 minutes, rotating the pan at the halfway mark, until the oat crumb topping is lightly browned.
Let cool to room temperature before slicing and serving.
