Frequently Asked Questions

Can I use steel-cut oats?

Steel-cut need more liquid and time; substitute only if you par-boil them 10 min and increase milk by ¾ cup. Texture will be chewier—more like a pudding.

Is this recipe vegan?

Swap eggs for flax-eggs, use plant milk and coconut oil. Final texture is slightly denser but still delicious.

Why did my blueberries sink?

Either berries were over-ripe/very wet or flour coating was skipped. Next time, pat berries dry and toss with flour.

Can I halve the recipe?

Yes—halve ingredients and bake in an 8×4-inch loaf pan for 25–28 min. Check center with toothpick.

How do I know when it’s done?

Edges will pull slightly from sides, top will be matte not glossy, and a toothpick inserted at a 45° angle near center will come out with a few moist crumbs—not wet batter.

Can I add protein powder?

Sure—replace ¼ cup oats with ¼ cup unflavored or vanilla whey. Add an extra 2 Tbsp milk to keep moisture balanced.
