Preheat the oven to 350℉/176℃ and line a loaf pan with parchment paper.
Add the flour, baking powder, salt, and onion powder (if using) to a large mixing bowl. Stir to combine. Then add the tahini, applesauce, and water and mix until combined and you have a thick batter.
Transfer the mixture to your loaf pan and evenly spread and smooth the top using a silicone spatula.
OPTIONAL: Sprinkle with seeds of your choice and gently press them down into the loaf.
Bake for approx. 45-50 minutes, or until a toothpick inserted into the middle of the loaf comes out clean and dry.
Remove from the oven and let cool to room temperature before slicing.
Notes
Weigh your flour for the best results. Flour volume will vary depending on measuring methods, such as the scoop and sweep, vs spooning your flour into the measuring cup. Use a kitchen scale for the most accurate flour measurement.
Use fresh + active baking powder! Baking powder that has been open in the pantry for 6+ months may start to lose its effectiveness.
Use parchment paper to line your loaf pan. This not only avoids extra fat from greasing the pan but also makes it simpler to remove the buckwheat bread from the pan once baked.
Cooking time will vary according to your loaf pan size, so always check “doneness” by inserting a toothpick in the center to see if it comes out clean. Mine is perfect at 45 minutes.
Let it cool. Give yourself extra time to let your loaf cool down. A minimum of 60 minutes on a cooling
