If you are using dry active yeast, you need to activate by adding 1/2 cup of lukewarm water and set aside for 5 minutes or when bubbles form. If you are using instant yeast you can directly add to dry ingredients.
2 tsp. active dry yeast or instant yeast, 1 cup lukewarm water
In a mixing bowl put bread flour, powdered milk, sugar and mix well together. (if you are using instant yeast, you can add it with the rest of the dry ingredients).
3 3/4 cups bread flour or all-purpose flour, 3 tbsp powdered milk, 1 1/2 tbsp. sugar
When the yeast mixture is activated (bubbles forming on top of mixture), add the egg and pour in with the dry ingredients.
1 large egg
Using a stand mixer with the hook attachment, mix everything in low speed until well incorporated.
Then add butter and salt and continue beating in low speed for 5 mins. When the butter mixed well with the dough continue beating in medium speed until your dough becomes soft and elastic.
3 tbsp. vegetable shortening or soften butter, 1/4 tsp. salt
Removed dough from mixing bowl then place it in another bowl greased with cooking oil and let it rise for 1 hour or depending on the humidity.
When the dough doubled in size you know you achieved a good rise. Dump the dough on the table or counter and punch the dough to release the air/gas inside.
Divide the dough in two equal parts. Set aside one part and cover with dry kitchen towel.
With the other dough, Flatten with a rolling pin and roll into a log shape and cut into small equal pieces (40 grams of dough) or approx. the size of a medium tomato.
Take one piece from the that you just cut and roll it into a shape of a ball. Flatten it with the rolling pin on a lightly flour dusted surface.
Take 2 tbsp. from the coconut filling that you set aside, put on the middle of the dough and seal by pinching all sides.
Place all the filled dough on a baking tray with parchment paper and let it rise for 20 minutes. While waiting you can pre-heat the oven (375°F or 180°C°).
Before baking apply eggwash (1 beaten egg + 1 tbsp milk) and poke the top of dough with fork.
Bake for 15 to 20 minutes at 375°F/180°C depending on the oven you are using or until golden brown. Serve warm or cooled. Bon appetit!
