In a small bowl pour the warm milk then add the dry active yeast. Let sit for 5 mins to bloom.
In a different bowl place the cereal flour/bread flour, sugar, salt. Mix until well incorporated.
When the yeast-milk mixture is ready pour into the dry ingredients then mix by hand until incorporated. Add ½ beaten egg then knead for 3 mins until it dough forms.
If you're using a stand mixer, attached bowl and use a hook attachment. Start mixer starting from the lowest speed. Increase speed after a minute or so.
Add vegetable oil then knead until the dough become smooth and elastic. (NOTE: do not dust your work surface with flour to avoid making the dough dry and hard).
Place the dough into a greased bowl and cover with cling film or clean kitchen towel and let it rest for 1 hour or until it doubles in size.
When the dough is double in size, lightly punch it to release air. Cut the dough into small sizes, approx. 50 grams each.
Take a piece of dough and form into a ball. Combine multi-grain cereal and bread crumbs in a bowl.
Roll the shaped dough in multi-grain cereal and bread crumbs and transfer them to a parchment-lined baking sheet. Cover with a kitchen towel and let rest again for 20 mins until double in size. While waiting, preheat oven at 160°c
After resting the dough place inside the preheated oven and bake for 20-25 mins.
Remove from the oven and let it cool for a couple of minutes. Bon appetit!
