This is what your gluten-free bread loaf should look like after you have smoothed it with the spreader spatula. If your bread looks like this you will end up with a nicely shaped loaf of bread.
Cover the batter loosely with plastic wrap and set the pan in a warm, draft-free location to rise. This takes about 30-45 minutes. The loaf should rise just about the top edge of your pan.
At this stage of prep, preheat your oven to 375° F / 190° C. For best baking results use an oven thermometer to make sure your oven temperatures are accurate.
