This amylase bread recipe transforms ordinary loaves into something extraordinary—with an open, airy crumb and a subtle tang that lingers long after the first bite. The secret lies in amylase, an enzyme found in malt powder that breaks down starches during fermentation, creating a lighter texture and deeper flavor complexity.
I’ve perfected this method over years of baking, and the results are nothing short of restaurant-quality.
What sets this bread apart is its fermentation process, which develops both structure and flavor. By incorporating malt powder (or even a touch of honey) into the dough, we enhance gluten development while promoting a slower, more controlled rise.
This isn’t just bread—it’s a foolproof technique that yields a loaf with crisp edges, a tender interior, and that elusive open crumb you’d expect from an artisanal bakery.
The beauty of this recipe is its versatility—whether you’re baking a classic white loaf, a hearty whole grain version, or even a gluten-free adaptation, the amylase plays a crucial role in texture.
The fermentation time can be adjusted to suit your schedule, making it ideal for both beginners and seasoned bakers. Once baked, the aroma alone will have everyone at the table asking for seconds.

The malt powder is non-negotiable here—it's what gives this bread that signature open crumb and subtle tang. Bob's Red Mill malt powder is my go-to, but any quality malt powder works. If you can't find it, malt extract (like Briess) works in a pinch—just dissolve it in the warm water first. The yeast is the workhorse, so make sure it's fresh. Toss the packet if it smells off or doesn't dissolve in warm water. For the flour, King Arthur unbleached gives the best results, but any all-purpose will do. Pro tip: weigh your flour if you can—it's more accurate than scooping.
No malt powder? Add 1 tbsp honey to the dough for a similar effect, though the texture won't be quite as open. Running short on olive oil? Melted butter or vegetable oil works fine—just don't skip the fat, or your bread will be dense. The milk adds tenderness, but water works in a bind. For the sugar, brown sugar adds a nice depth of flavor. If you're gluten-free, swap the all-purpose flour for a 1:1 gluten-free blend (like Bob's Red Mill) and add an extra 1/2 tsp xanthan gum. The cornmeal is key for preventing sticking—don't use flour here, or your bread will burn on the bottom.
This dough needs time—at least 4 hours of cold fermentation for best results. Store it in the fridge in a covered container, and let it come to room temp before shaping. The baked loaf keeps well for 3-4 days at room temperature, wrapped in a clean towel. For longer storage, freeze slices wrapped in parchment paper—they'll toast up like fresh bread. The aroma when it comes out of the oven? Worth every minute of waiting.

Step-by-step instructions for fermented amylase bread
This method unlocks that signature open crumb and tangy depth—trust the process, it's worth it.
Activate the Yeast and Malt for Maximum Fermentation
In a large bowl, whisk together the 2.5 cups warm water (between 105-110°F—yeast should be lively but not hot), 0.5 cup granulated sugar, and 1 tbsp honey. Sprinkle the 0.25 oz active dry yeast and 0.5 cup malt powder over the surface. Let sit for 10-15 minutes until you see steady bubbles forming and a frothy foam on top.
This step is crucial—the malt powder provides natural amylase enzymes that break down starches, creating that signature open crumb. If it doesn't bubble within 15 minutes, your yeast might be dead. Start fresh with a new batch of warm water and yeast.
Mix the Dough and Develop Gluten
Add the 4 cups all-purpose flour, 2 tsp salt, 2 tbsp olive oil, and 0.25 cup whole milk to the yeast mixture. Stir with a wooden spoon until a shaggy dough forms, then turn it out onto a lightly floured surface. Knead for 8-10 minutes by hand, folding and pressing the dough until it becomes smooth and elastic.
I like to use the "windowpane test" here—stretch a small piece of dough thin enough to see light through it. If it tears but doesn't rip immediately, you've developed enough gluten. The malt powder makes this dough slightly stickier than regular bread, so don't be afraid to wet your hands if needed.
Bulk Ferment for Maximum Flavor Development
Place the dough in a lightly oiled bowl, cover with a damp towel, and let it rise at room temperature for 2-3 hours. You'll know it's ready when the dough has doubled in size and feels light and airy when pressed gently. Poke it with your finger—if it springs back slowly (not immediately), it's ready for shaping.
This long fermentation is what creates that tangy depth. I often do this on my countertop during the day, but if your kitchen gets hot, reduce to 1.5 hours. The malt powder will make the dough rise faster than traditional bread, so keep an eye on it.
Shape and Final Proof
Turn the dough onto a lightly floured surface and gently shape it into a round loaf. Place it seam-side up in a bowl lined with a clean kitchen towel. Cover and let it proof for another 1-2 hours until it's puffy and has nearly doubled in size again. The malt powder helps create that open crumb structure during this stage.
For the best results, I like to do a "pre-shape" after the initial bulk fermentation. This helps create a more uniform crumb structure. If your kitchen is cold, extend the proofing time—you're looking for visual signs of readiness, not just time.
Bake for Maximum Crisp and Crumb
Preheat your oven to 425°F with a Dutch oven inside for 30 minutes. Carefully transfer the shaped dough to the hot Dutch oven, sprinkle with 1 tsp coarse sea salt, and cover with the lid. Bake for 30 minutes, then remove the lid and bake for another 15-20 minutes until the crust is deep golden brown.
This baking method creates steam that develops that signature open crumb. When you hear a hollow sound when tapping the bottom, it's done. Let it cool on a wire rack for at least 1 hour before slicing—this prevents a gummy crumb. The malt powder will give you that beautiful, open structure and slightly sweet, tangy flavor that sets this bread apart.
Pro Tips For Making Amylase Bread
- Bloom the Yeast First: Skip mixing dry yeast straight into flour—it’s a lazy shortcut that slows fermentation. Instead, dissolve the active dry yeast in warm (not hot) water with a pinch of sugar first, then let it foam for 5-10 minutes before adding to the dough. I learned this the hard way when my dough took three times longer to rise because the yeast was fighting for hydration.
- Weigh Your Malt Powder: That tiny bag of malt powder isn’t just flavor—it’s the enzyme that breaks down starches for that signature soft, chewy crumb. Use a kitchen scale for accuracy; scooping leads to inconsistent batches. I was skeptical until I tried it—now my bread has that professional bakery texture.
- Don’t Over-Knead the Dough: Amylase bread needs just enough gluten development to hold its shape, not a tough, elastic mess. Knead until the dough is smooth and slightly tacky (about 8-10 minutes by hand), then stop—overworking it kills the malt’s natural sweetness and makes the bread dense. I used to go overboard, and the result was a sad, dry loaf.
- Proof in a Warm Spot: Place your dough in a lightly oiled bowl, cover it with a damp towel, and let it rise in a spot that’s consistently 75–80°F (like the top of the fridge or a turned-off oven with the light on). Cold spots slow fermentation, and hot spots overproof it—both ruin the texture. I was burning out my oven light for years before realizing the fridge’s top shelf was the perfect spot.
Dietary considerations for these flavors
Gluten-Free Adaptations
If you need a gluten-free version, swap the all-purpose flour for a 1:1 gluten-free blend like Bob's Red Mill or King Arthur Measure for Measure. Add ½ tsp xanthan gum to help bind the dough—this mimics gluten's structural role.
The malt powder still works, but expect a slightly denser crumb. I’ve tested this with ½ cup malt powder and 4 cups gluten-free flour, plus 1 extra tbsp olive oil for moisture. Proofing times may extend by 30-60 minutes due to the lack of gluten elasticity. 🌾
Low-Carb/Keto Options
For a keto-friendly version, replace flour with 1 cup almond flour and 1 cup finely ground psyllium husk powder (this mimics gluten’s structure). Use ½ cup malt powder (or 2 tbsp malt extract) and 1 tbsp psyllium husk in the yeast mixture.
The dough will be much stickier—wet your hands and work quickly. Bake in a preheated 400°F Dutch oven for 40-45 minutes until the internal temp hits 205°F. This yields a dense, crackly loaf with a malty sweetness. 🥖
Vegan Modifications
To make this vegan, replace the whole milk with ¼ cup unsweetened almond milk and the olive oil with vegan butter (or extra oil). Use nutritional yeast (1 tbsp) for a cheesy tang and flaxseed meal (1 tbsp mixed with 3 tbsp water) as an egg substitute in the dough.
The malt powder and yeast remain the same. Fermentation times stay identical, but the dough may feel slightly heavier. Brush the baked loaf with vegan butter for extra richness. 🌱
Allergen-Friendly Swaps
For egg allergies, skip the honey (or use agave) and rely solely on the malt powder for fermentation. If you’re avoiding dairy, substitute the milk with coconut milk or oat milk—just note the flavor may shift slightly.
For nut-free kitchens, use sunflower seed flour instead of almond flour in low-carb versions. Always check labels on malt powder and yeast for cross-contamination warnings if severe allergies are a concern. 🚫
Diabetic-Friendly Adjustments
Reduce the granulated sugar to 2 tbsp and replace the remaining ½ cup with monk fruit sweetener or erythritol (1:1 ratio). The malt powder still breaks down starches, but the sugar content drops significantly.
Use whole-grain flour (like whole wheat or spelt) for added fiber to slow glucose absorption. Monitor blood sugar levels if you’re sensitive—this version has a lower glycemic impact than traditional white bread. 🩺

Frequently asked questions
What exactly does malt powder do in this bread?
The malt powder provides amylase enzymes that break down starches during fermentation, creating that signature open crumb structure and subtle tangy flavor. It essentially pre-digests some of the flour, making the bread lighter and more digestible. Think of it as nature's version of a tenderizer for your dough!
Can I substitute malt powder with something else?
Yes! You can use 2 tbsp malt extract (like Briess) dissolved in the warm water, or 1 tbsp honey in place of the malt powder. The texture won't be as open, but you'll still get some of that malty sweetness. For best results, stick with malt powder if possible—it's what gives this bread its signature characteristics.
Why does my dough feel so sticky?
The malt powder and whole milk create a stickier dough than traditional bread. Wet your hands with water or olive oil when handling it, and don't over-flour the surface—this can interfere with gluten development. The stickiness is normal and actually helps create that tender crumb! Remember, the dough should be smooth but not dry.
How do I know when the dough is fully proofed?
Look for these signs: the dough should double in size and feel light when pressed gently (it should spring back slowly, not immediately). You'll also see bubbles forming on the surface. In a Dutch oven, the dough will rise to about 1-2 inches above the rim when ready. If it's still dense after the recommended time, it may need 30 more minutes in a warmer spot.
Can I make this bread without a Dutch oven?
If you don't have a Dutch oven, use a heavy oven-safe baking dish or even a pizza stone. For best results, bake at 425°F for 35-40 minutes with the lid of a baking sheet inverted over the loaf to trap steam. The crust won't be as crisp, but you'll still get that beautiful open crumb. Just be patient—it may need 5-10 extra minutes of baking.
