In a large bowl, add the plain flour, eggs, milk, sunflower and a pinch of salt, then whisk to a smooth batter.
In a frying pan over a medium heat, add a little oil and a knob of butter and when hot, pour in your pancake mix and cook for 1 min on each side until golden. (I look for little bubble forming on the top of the pancake as a sign that it's almost ready to flip)Once done on both sides, pop into the oven (on low) to keep warm.
While you are making the pancakes, grill some streaky bacon (and pop in the oven until all your pancakes are done).Once you've finished the pancakes, add a knob of butter to the frying pan and cut your banana's in half length-ways and caramelise them.
Serve you pancakes so your guests can help themselves to them and the toppings they want to add on.
