First you must prepare the gingerbread cake recipe as per the instructions on that post but not he icing unless of course you prefer to have cream cheese icing for your finished buns rather than the glaze recipe listed
Once the cake is baked & cooled, make the gingerbread filling by crumbling the cake with the brown sugar & all the spices listed for the gingerbread filling into a large mixing bowl, mix by hand or with a whisk~ reserve (*this can be done a week ahead of time & refrigerated or frozen until needed)
Combine the other measure of vegan butter listed with the "filling ingredients" with the molasses & heat to melt the butter & whisk smooth with the molasses~ reserve
To Make the Dough: Grease a 9" X 13" X 2" cake pan *No parchment paper liner!
Combine the yeast with the warm milk & a pinch of sugar ~ let stand for 5 minutes
In a mixing bowl combine the flour with the nutmeg, sugar & salt, stir to distribute well
Add the milk with the yeast, the banana puree & the softened butter then add all of the sifted dry ingredients on top of that.
Mix with the dough hook ~ you may need to help it along with a spatula until it forms a soft mass, then let it knead for 5 minutes on medium speed to develop the doughAdd more flour to adjust the consistency as needed *see video demonstration Turn mixer speed to low & mix for another 3 minutes
Once it is to desired consistency and properly kneaded for a total of about 8 minutes You will notice in the video I said "you want a dough that doesn't clear the sides of the bowl" I meant to say "One that DOES clear the sides of the bowl" Sorry!
Transfer to a lightly oiled bowl covered & let rise to double in a warm spot
Roll out the doubled dough on a lightly floured surface to 12" x 18" & about ¼" thick
Brush with the melted butter/molasses & then spread evenly with the brown sugar & cake crumbles spice mixture
Roll up the dough jelly roll style with the wider edge towards you, then cut into desired portions ~ cutting the log into 12 pieces for giant bakery size buns
Place them into the prepared 9" x 13" pan
Cover loosely and let rise again covered in a warm spot. approximately 60 minutes depending on the conditions in your area *Or for AM bakers this is where you would refrigerate overnight *see notes Once they are light and fluffy & puffy and almost doubled in size & the buns are touching each other, brush gently with the "prebake glaze" *optional
Bake in a preheated 350°F oven for 20 minutes, then I like to turn the temperature down to 325°F for another 15-20 minutes, depending on the size of your buns
While the buns are baking you can prepare the glaze icing by combining the sifted confectioners sugar with the plant milk & whisk smooth
Once the buns are out of the oven & cooled just slightly pour the glaze over the hot buns in the pan & spread over the buns evenly
