Preheat the oven to 350°F (180°C). Line a bread tin with baking paper.
Place the eggs, baking soda and tahini in a bowl and mix with a hand mixer until well combined.
Pour the batter into the bread tin and sprinkle over the sesame seeds. Place the tin into the hot oven to bake for 30 minutes.
Once baked, remove the tin from the oven and place on a wire rack to cool completely before slicing and serving.
