Preheat the oven to 170°C. Grease a 6 cup bundt cake pan with butter or cooking spray.
Place the eggs and sugar in a large mixing bowl. Beat together at high speed until the mixture gets fluffy.
Add oil, tahini paste, and milk and mix at medium speed just to combine.
Add baking powder and vanilla seeds and mix on medium speed again just to combine.
At the end add flour and mix on low speed to combine.
Bake for 45-50 minutes or until a toothpick inserted into the middle of the cake comes out clean.
Remove from the oven and leave the cake in the pan. Cover with a cloth and leave to rest for 10-15 minutes. This will make the cake come out easily.
Remove from the pan and leave to cool down before glazing.
Blend kiwis in a blender. Pour the pureé in a bowl and add icing sugar. Whisk until well combined. Add heavy cream and mix again.
Pour the glaze over the cooled tahini bundt cake
