Combine warm water, white sugar, oil, salt, and egg in a mixing bowl.
Add 2 cups of the spelt four, one cup of the white flour, and the instant yeast. Mix well.
Add the rest of the spelt and white flour to the dough and mix well again.
Knead the dough for 6-8 minutes. If the dough is sticking to your fingers while kneading then add more flour.
Roll the dough into a ball and place it in a greased bowl. Cover with a towel or plastic wrap and put it somewhere warm to rise until double the size (roughly 2 hours.)
Divide the dough into two and take one section and roll it onto a floured surface into a rough rectangle shape.
Take half the butter and cut into chunks. Drop the chunks evenly onto the dough.
Take half the brown sugar and sprinkle it onto the dough.
Sprinkle 1 tbsp of cinnamon onto the dough.
Starting at the bottom, roll your dough into a long log shape.
Cut the dough into 2 inch pieces.
Take your second section of dough that you put aside earlier and do the same as you did with the first section of dough.
Coat your baking pan with butter and then sprinkle the bottom with brown sugar.
Place your buns into the pan with a bit of space in between.
Cover the buns with a towel and set aside to rise for about 45 minutes, or until double in size.
Preheat the oven to 350 F.
Bake the buns for 22-24 minutes. DO NOT OVERBAKE. You want them to start to turn golden brown but to not be too dark.
Let cool - but not too much - they taste best when warm!
