In a stand mixer, combine flour, yeast, sugar, salt in a bowl. Stir in milk followed by coconut oil. Mix on low speed until a rough ball begins to form. Continue to knead on low speed for another 5 mins, or until the dough ball turns smooth. Or beat on high for 3 minutes until dough forms a mass. On a floured surface, knead dough about 4-5 minutes by hands.
Cover dough and let it rest for 15-20mins.
In small saucepan add frozen berries, sweetened, lemon juice and bring to boil. Once boiling, lower the heat and let it simmer for 10mines (stir occasionally). Add sweetened and cook for more 5mines. Turn off the heat and let it cool.
You can use a sharp knife, but I prefer to cut each roll with dental floss, which doesn't flatten them. Cut into 8 equal pieces. Place them in a 8 inch prepared pan. Cover with plastic and let rest for 1 hr or until rolls have almost doubled in size.
Preheat oven to 180degrees Celsius. Brush the coconut oil on evenly, all the way to the edges. Bake for 18-20 minutes just until rolls are lightly golden around the edges and centers are puffed and cooked thoroughly.
Remove from the oven and let it cool slightly before serving. Enjoy.
