Ingredients for amylase bread
Light, airy loaves start with these science-backed ingredients—amylase enzymes and malted flour do the heavy lifting.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 3 ½ cups | High-protein for better structure |
| Malted Barley Flour 🌾 | ½ cup | Enzyme-rich for amylase activity |
| Amylase Enzyme Powder 🧪 | ¼ tsp | Commercial grade for consistent rise |
| Active Dry Yeast 🍞 | ¾ tsp | Freshly opened for best activity |
| Granulated Sugar 🍚 | ½ tsp | Feeds yeast for fermentation |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Water 💧 | 1 ¾ cups | Lukewarm for optimal yeast activation |
| Olive Oil 🫒 | ¼ cup | Extra-virgin for richness |
| Honey 🍯 | 1 tbsp | For crust browning and flavor |
| Instant Vital Wheat Gluten 🌾 | ½ tsp | Optional for enhanced structure |
| Cornmeal 🌽 | ¼ cup | For dusting baking sheets |

The malted barley flour is non-negotiable here—it contains natural amylase enzymes that break down gluten for that signature tender crumb. Bob's Red Mill malted barley flour is my go-to, but any quality brand will work. If you can't find malted barley flour, commercial amylase powder (available online) does the trick—just follow package instructions for dosage. The yeast and sugar team up to kickstart fermentation, but don't overmix once combined. The 50% hydration ratio keeps things manageable for beginners while still delivering professional results. For the enzyme powder, Amazon or specialty baking stores carry it, and a little goes a long way—measure carefully.
No malted flour? Substitute with an extra 0.25 tsp amylase powder (adjust hydration slightly if needed). Running low on yeast? Instant yeast works 1:1, but fresh yeast requires a bit more time to activate. The olive oil adds richness, but vegetable or melted coconut oil works in a pinch. For the honey, any liquid sweetener will do—maple syrup or agave are great swaps. The vital wheat gluten is optional but helps if your flour lacks protein. If you skip it, increase hydration slightly to compensate. The ice water at the end is key—it tightens the gluten just enough for shaping without overworking the dough.
This dough is surprisingly forgiving, but store it right for best results. Ferment in the fridge overnight for deeper flavor and easier handling—just pull it out 2 hours before shaping. The shaped loaves keep 2 days at room temperature wrapped in a clean towel, or 1 week in the fridge. For longer storage, freeze shaped loaves (unbaked) for up to 3 months

Step-by-step instructions for science-backed amylase bread
This isn't your average bread recipe—we're leveraging malted barley and amylase enzymes to create a loaf with professional bakery texture.
Activate the Yeast and Enzymes
In a large bowl, whisk together the 1.75 cups lukewarm water, 0.5 tsp granulated sugar, and 0.75 tsp active dry yeast. Let this sit for 5-7 minutes until you see vigorous bubbling—this confirms the yeast is alive and ready to work. The sugar helps jumpstart fermentation, while the malted barley flour's natural enzymes will kick in later to break down starches for that signature lightness.
In a separate small bowl, whisk together the 0.5 cup malted barley flour and 0.25 tsp amylase enzyme powder. This combination is what sets this bread apart—malted barley contains natural diastatic enzymes, while the commercial amylase ensures consistent starch breakdown. Sprinkle this mixture into the yeast water and stir gently to combine. Let this mixture sit for another 5 minutes while you prepare the remaining ingredients.
Mix the Dough Foundation
To the yeast mixture, add the 3.5 cups all-purpose flour, 1.5 tsp salt, 0.5 tsp instant vital wheat gluten, and 0.25 cup olive oil. Using a wooden spoon or dough whisk, mix vigorously for 3-4 minutes until you have a shaggy, sticky dough. The gluten begins developing now, giving your bread that professional structure. Don't be tempted to add extra flour—this recipe is designed to be slightly wet for optimal enzyme activity.
Add the 1 tbsp honey and mix again. The honey serves dual purposes: it feeds the yeast during fermentation and contributes to that beautiful caramelized crust. At this stage, your dough should be thick but still quite sticky—this is normal and actually ideal for our enzyme-driven approach.
Develop the Dough Through Autolyse
Cover the bowl with a damp towel and let the dough rest for 20 minutes. This autolyse period allows the gluten to relax and the flour to fully hydrate before we add the final ice water. During this time, the amylase enzymes begin breaking down starches into simpler sugars, which will feed the yeast later and contribute to that signature airy crumb.
After 20 minutes, add the 0.25 cup ice water and mix just until combined. The cold water shocks the gluten development slightly, creating a more open crumb structure. The dough will feel even stickier now—this is where the science pays off. The combination of malted barley enzymes and commercial amylase creates a unique environment where starches break down more efficiently than in traditional bread.
Bulk Ferment for Maximum Rise
Lightly oil a large mixing bowl and transfer the dough to it. Cover with plastic wrap and let ferment at room temperature for 1.5-2 hours. You're looking for about 50-75% increase in volume—the dough should feel soft and slightly springy when poked. The amylase enzymes are actively working during this time, breaking down starches into fermentable sugars that the yeast can consume, resulting in a more extensive rise.
Every 30 minutes, perform a "windowpane test": wet one finger and poke the dough. If the membrane stretches thin enough to see light through without tearing, it's ready. If not, give it more time. The malted barley flour contributes additional enzymes that accelerate this process compared to traditional bread doughs.
Shape and Final Proof
Gently turn the dough onto a lightly floured surface and shape into a round boules. The enzymes have done their work, so handle the dough gently to preserve the air pockets created during fermentation. Place the shaped dough seam-side up on a parchment-lined baking sheet dusted with 0.25 cup cornmeal. Cover and let proof for 45-60 minutes until nearly doubled in size.
The cornmeal creates a textured crust while preventing sticking. The final proof is crucial—it allows the yeast to fully ferment the sugars created by the amylase enzymes, resulting in that signature light, airy crumb. When ready, the dough should spring back slowly when poked, with a slight indentation remaining from your finger.
Bake for Perfect Crust and Crumb
Preheat your oven to 375°F with a Dutch oven inside for 30 minutes. The Dutch oven creates steam, which is essential for developing that professional bakery crust while keeping the crumb tender. Carefully transfer the dough (still on parchment) into the hot Dutch oven and bake, covered, for 30 minutes. Then remove the lid and bake for another 15-20 minutes until the crust is deep golden brown.
The internal temperature should reach 190-195°F when checked with an instant-read thermometer. The amylase enzymes have broken down starches during fermentation, which now contribute to that signature moist crumb even after baking. Let the bread cool on a wire rack for at least 1 hour before slicing—this allows the gluten to fully relax and prevents a gummy texture.
Pro Tips For Making Amylase Bread
- Bloom the yeast first: Skip mixing yeast into dry ingredients—it’s a waste. Instead, dissolve it in warm water (105–110°F) with sugar first and let it foam for 5–10 minutes. This guarantees your yeast is active before it hits the barley flour, which can be a little stubborn with wild fermentation.
- Whisk in amylase last: I learned this the hard way—adding amylase enzyme powder too early turns your dough into a sticky mess. Sprinkle it over the finished mixed dough just before kneading, then work it in quickly. The enzyme breaks down starches fast, so don’t let it sit in flour for more than 30 seconds.
- Don’t overmix with barley flour: Malted barley flour is grittier than all-purpose, and overworking it turns your dough into a paste. Mix just until the dry ingredients disappear, then switch to folding by hand. The gluten will develop enough without turning your bread dense—trust the process, even if it looks uneven.
- Proof at 78°F, not warmer: Yeast loves warmth, but barley flour’s natural enzymes get aggressive above 80°F. Use a proofing box or turn off your oven with the light on to hit 78°F—this keeps fermentation steady without overworking the yeast. Overproofed amylase bread collapses like a sad soufflé.
Make-ahead tips for this dish
Pre-Ferment Prep
Make your dough the night before for deeper flavor and easier handling. After mixing, divide the dough into two loaf pans or shape into boules, then refrigerate covered for 12-16 hours. The cold slows fermentation, allowing enzymes to work more efficiently and develop complex flavors.
When ready to bake, remove from the fridge and let sit at room temperature for 1-2 hours until slightly puffy. This cold fermentation also improves gluten structure, making shaping a breeze. 🧊
Freezer-Friendly Dough
For ultimate convenience, prepare the dough up to the shaping stage, then freeze it in airtight containers or freezer bags for up to 3 months. When ready to bake, thaw in the fridge overnight, then proceed with shaping and proofing.
The enzymes remain active even after freezing, ensuring your bread still develops that signature light crumb. I often make two batches on weekends—one for immediate use and one to freeze for busy weeknights. 🥶
Bulk Dough Storage
If you've already shaped your loaves but aren't ready to bake, store them in the fridge for up to 24 hours before baking. Place them seam-side up on a parchment-lined tray, loosely covered with plastic wrap.
The cold environment preserves the yeast activity while maintaining the delicate air pockets created by the amylase enzymes. When you're ready to bake, simply remove from the fridge, let sit for 30 minutes to come to room temperature, then proceed with the baking instructions.
This method works perfectly for meal preppers who want to schedule baking around their schedule. ⏰
Baked Loaf Preservation
Your freshly baked amylase bread stays fresher longer than traditional loaves—up to 5 days at room temperature when wrapped in a clean kitchen towel. The enzymes break down starches in a way that retains moisture better than standard bread.
For longer storage, slice the cooled loaf and freeze individual slices between parchment paper for up to 3 months. To reheat, wrap slices in foil and warm in a 350°F oven for 5-7 minutes or use the microwave with a damp paper towel for 10-15 seconds.
The texture remains tender and the crust stays crisp. 💫
Batch Baking Tips
Double or triple this recipe for batch baking—just ensure your Dutch oven can accommodate the size. For large batches, divide the dough into 16-ounce portions before final proofing.
The amylase enzymes work consistently across different batch sizes, so you'll get the same light, airy texture whether you bake one loaf or four. I recommend baking two loaves at a time in the Dutch oven, spacing them slightly apart for even browning.
The enzymes help maintain consistent texture even with larger quantities. 🔥
Equipment Shortcuts
No Dutch oven? Use a heavy baking sheet with a metal bowl inverted over the loaves during the first 20 minutes of baking to create steam. The amylase process is forgiving enough that you'll still get a good rise and tender crumb, though the crust may be slightly less crisp.
For shaping, a well-floured surface works fine—just handle the dough gently to preserve those enzyme-created air pockets. The key is maintaining proper fermentation times regardless of equipment. ✨

Frequently asked questions
What exactly does amylase do in bread?
Amylase enzymes break down starches in flour into simpler sugars during fermentation. This creates more food for yeast, accelerating rise while softening gluten for a lighter, airier crumb. The result is bread that stays tender longer and has a finer texture than traditional loaves. Think of it as a natural tenderizer and fermentation booster combined!
Can I use this recipe without malted barley flour?
Yes! Simply increase the commercial amylase powder to 0.5 tsp and use all-purpose flour. The enzymes will still work, though malted barley adds natural complexity. For best results, combine both—0.25 tsp enzyme powder plus 0.25 cup malted flour gives you the full enzyme benefit without overpowering the flavor.
Why is my dough so sticky?
The 50% hydration ratio and enzyme activity create a naturally sticky dough—this is normal and actually ideal! The amylase breaks down starches, releasing moisture. To handle it, wet your hands or use a dough scraper. Avoid adding extra flour, as this can interfere with the enzyme process and create a denser crumb.
How do I know when the dough is fully fermented?
Perform the "windowpane test": wet one finger and poke the dough. If it stretches thin enough to see light through without tearing, it's ready. For this recipe, look for 50-75% volume increase during bulk fermentation (1.5-2 hours). The malted barley enzymes accelerate fermentation, so don't overproof—your dough should feel soft but still slightly springy.
