Use This ToolWhen I went gluten-free six years ago, I burned through more flour blends and sunken loaves than I'd like to admit. The biggest frustration wasn't finding recipes — it was the math. How much xanthan gum for sandwich bread vs. cookies? What's the right hydration for GF sourdough?
None of the generic baking calculators online accounted for gluten-free flour behavior. So we built our own — based on ratios tested in real recipes and refined through feedback from thousands of home bakers.
Yes, every calculator and guide on this page is completely free. We built them to make gluten-free baking less stressful — no account required, no paywalls.
Our flour calculator is based on ratios we've tested across 200+ recipes over six years of gluten-free baking. The blends account for protein content, starch ratios, and binding needs specific to each recipe type. That said, every oven and flour brand behaves a little differently, so treat the results as a strong starting point and adjust to your taste.
Absolutely. Every tool is designed mobile-first, so you can pull it up right in the kitchen while you're measuring ingredients. No app download needed.
Several of our tools work across dietary needs. The Dairy-Free Substitution Guide covers vegan and lactose-free swaps, the Recipe Scaler works for any recipe regardless of diet, and our Baking Converter handles standard and GF ingredients alike. We're adding more allergy-specific tools based on what our community asks for.
Everything is based on hands-on testing by the Bloom kitchen team, combined with food science references for protein structures, hydration properties, and binding behavior. We don't just pull ratios from the internet — each recommendation has been baked (literally) into real recipes on this site.
