Preheat the oven to 350°F (180°C). Line a 9-inch x 5-inch loaf pan with parchment paper.
In a mixing bowl, whisk self-rising flour, sugar, and salt if used.
Add the can of beer and olive oil and stir with a rubber spatula at first, then oil your hands and knead to form a sticky thick bread dough.
Place the dough into the loaf pan, wet the top with some water, and press any seeds you like on top.
Bake the bread for 50-60 minutes at 350°F (180°C) until golden brown on top and a skewer inserted in the center of the bread comes out clean.
Let it cool down on a rack for 3 hours before slicing.
