It’s a Beavertail! (A type of Canadian pastry). To everyone on the interwebz wondering what this is, it’s a nutella-banana Beavertail; a Beavertail is a flat whole-wheat donut covered in whatever toppings you desire. The standard Beavertail is topped with lemon and sugar and is actually not that horrible for you. They sell them in Ottawa and various other Canadian cities - especially touristy areas. What a shame to post it without a caption explaining it!
