Preheat oven 200C | 390F. Spray an 8x8-inch baking pan with cooking spray, wipe excess over with a paper towel and set aside.
Throw ALL ingredients (except the nutella and jam) into a food processor and blend until smooth (about 5 minutes, depending on your food processor)
Pour into a prepared pan and spoon jam and nutella evenly over batter.
With the back of a spatula of knife, swirl both spreads into the batter and over the top until the surface is covered.
Bake for approx 25 - 30 minutes (depending on your oven) until a toothpick inserted into the centre comes out semi-clean. (The dirtier the toothpick, the fudgy-er the bars)
They are VERY moist when taken out, but they will set and firm as they cool! Don't over cook these - or they will become dry.
Once cooled, gently cut into 16 bars.
