From here, with slight modifications
Preheat oven to 380F put a 9-inch cast iron skillet in to heat up. Melt
1 stick butter
in microwave (30 sec) and set aside.
In large blender bowl, mix
1c. flour
1c cornmeal or polenta
1/4c light brown sugar
1t baking powder
1/2t baking soda
1/4t salt
4T buttermilk powder
In small blender bowl, mix
2 large eggs
2T honey
and then add
1 c warm water and mix more
Pour the liquid into the flour mix and mix to combine (don't overmix); then add the melted butter and mix a little more. Remove from blender, and grab a spatula to help ease it into the cast iron pan in a moment.
Remove the cast iron pan from the preheated oven, and wipe it down with
1/2 T butter on a paper towel
Then pour
the batter
into the cast-iron pan, using the spatula to get those last bits.
Place in the oven for 20 min. Check that a toothpick or skewer inserted in the center comes out clean, and that the internal temp is about 198-200. It probably won't be, and may need another 4-5 min. of cooking.
When it's really done, remove from oven, loosen, and flip onto a plate, and then flip back onto a cooling rack. Let cool 10 minutes before slicing/serving.
