These buttery Oatmeal Jam Bars are an easy, crowd-pleasing treat! A soft oatmeal cookie base, a layer of fruity jam, and a crumbly cookie topping—pure dessert perfection.
Preheat oven to 350°F. Line an 8x8-inch pan with parchment paper (I don’t recommend foil), leaving an overhang for easy removal. Melt the butter and let it cool slightly to avoid greasy bars.
Whisk melted (cooled) butter, brown sugar, and vanilla until fully integrated; it will seem like they won’t, keep whisking until completely integrated.
Combine flour, oats, salt, and baking soda into a thick dough using a wooden spoon or spatula. Press just over half into the pan in an even layer. Bake for 8 minutes and remove.
Spread jam over the base, avoiding the edges to prevent burning. Gently layer without pressing into the base. Sprinkle remaining oat mixture on top without pressing down.
Continue baking for 13–18 minutes until the top is lightly golden. Cool at room temperature on a wire rack for at least 2 hours before cutting; they firm up as they cool (see note 1).
