2tspbaking powder

283gwhole milkI use semi-skimmed and it’s fine
3large eggs
56gfrozen corn
Instructions
Grease a round pan (approx. 8 to 10 in.) (see Cookidoo Tip) and preheat oven to 425°F/200°C.
Place the cheese into the mixing bowl and grate 4 seconds/speed 7. Transfer to a bowl and set aside.
Place the jalapeños into the mixing bowl and chop 3 seconds/speed 5. Scrape down the sides of the mixing bowl with the spatula.
Add the cornmeal (polenta), flour, sugar, salt, baking powder, baking soda, canola oil, milk and eggs and mix 10 seconds/speed 4.
Add the reserved grated cheese and frozen corn and mix 5 seconds/reverse/speed 4. Transfer the batter into the prepared pan and bake for 20 to 25 minutes or until golden brown (see Tips). Allow to cool before serving.
Notes
I'd recommend turning the cornbread half way through cooking so that it browns evenly.
At the end of the cooking time, use a skewer or sharp knife to test that it's cooked right through - the skewer/knife should come out clean. Extend cooking time by 5 minute intervals and keep checking that the skewer/knife comes out clean before removing from oven to cool slightly before removing it from the pan.
Cookidoo Tip
To bake in a cast iron skillet: place 1 tbsp canola (or sunflower) oil into a cast iron skillet (approx. 8 to 10 in.) and place in the oven. Preheat oven to 425°F/ 220°C and continue making the batter. Carefully transfer the batter from the mixing bowl into the hot skillet and bake for 20 to 25 minutes or until golden brown.
