A completely oat-free, gluten-free-protein-banana-bread.html" class="text-brand-600 hover:text-brand-700 font-semibold" title="Gluten-Free Protein Banana Bread">gluten-free, dairy-free, and sugar-free protein banana bread that delivers on both taste and gut health. Built on a base of white rice flour, tapioca starch, and tigernut flour — a prebiotic-rich tuber that's naturally nut-free — this loaf gets its protein from banana-flavored pea protein isolate instead of whey. The secret to its satisfying texture is a trio of soluble fibers: acacia fiber, PHGG, and glucomannan, which mimic the binding properties of oats while feeding beneficial gut bacteria. Sweetened entirely with monkfruit/erythritol and ripe bananas, each slice delivers 9g protein and 7g fiber at just 183 calories. The 1.5x batch is designed specifically for an 8-inch loaf pan, baking low and slow at 375°F for a perfectly browned crust and tender crumb. For maximum resistant starch (RS3) benefits, wrap and refrigerate the loaf overnight before slicing — then toast or rewarm slices as desired. This is the ideal bread for anyone managing celiac disease, oat sensitivities, or a strict low-sugar lifestyle who refuses to compromise on a warm slice of banana bread.

INSTRUCTIONS
Preheat oven to 375°F (190°C). Line an 8-inch loaf pan with parchment paper or grease well. No initial high-heat blast needed for loaf format.
In a large bowl, whisk together rice flour, tapioca starch, tigernut flour, pea protein, flaxseed, chia seeds, acacia fiber, PHGG, glucomannan, baking powder, baking soda, salt, and cinnamon. Whisk thoroughly for at least 60 seconds — clumps of glucomannan will create gummy pockets in the finished bread.
Mash bananas until smooth (360g by weight). Whisk in applesauce, eggs, monkfruit sweetener, vanilla, and 315ml plant milk. Pour wet into dry and fold gently until just combined. Rest batter 3-5 minutes so fibers and protein hydrate. If batter is too thick to pour with help of a spatula, fold in up to 15ml more plant milk.
Pour batter into prepared loaf pan and smooth the top. Bake at 375°F (190°C) for 40-50 minutes. Start checking at 38-40 minutes — loaf is done when a skewer comes out mostly clean from center and top is well browned and springs back when pressed.
Cool in pan 15-20 minutes, then lift out to a wire rack until fully cool. For maximum resistant starch (RS3) benefits, wrap the loaf and refrigerate overnight before slicing. Toast or rewarm slices as desired.
TROUBLESHOOTING
My breads are too dry
Try adding 1-2 tablespoons more liquid (milk, yogurt, or egg whites). Also ensure you're not over-measuring the protein powder - use the scoop and level method.
They didn't rise properly
Check your baking powder is fresh (test by adding to hot water - it should bubble vigorously). Also, don't overmix the batter as this can deflate the air bubbles.
The texture is rubbery
This usually means too much protein powder or overbaking. Reduce baking time by 2-3 minutes and check doneness with a toothpick.
