Amylase Bread Recipe: Fermented Flavor Without Gluten Grains

This amylase bread recipe transforms ordinary loaves into something extraordinary—fermented, flavorful, and perfectly digestible without relying on gluten grains. The secret lies in amylase, an enzyme found in malted flour or powder, which breaks down starches into sugars, fueling yeast activity and creating a lighter, more digestible crumb.

I developed this recipe after years of experimenting with fermentation techniques, and it consistently delivers a bread with an open crumb, improved rise, and a subtle sweetness that sets it apart.

The process begins with a simple dough made from flour, water, and yeast, but the addition of malt powder or malted flour is what truly elevates it.

Amylase activates during fermentation, breaking down starches into fermentable sugars that feed the yeast, resulting in a more extensive rise and a softer texture. Unlike traditional breads, this recipe doesn’t require gluten grains, making it a versatile option for those seeking a lighter, easier-to-digest loaf without compromising flavor or structure.

Baking at 375°F (190°C) for 30–45 minutes ensures a golden crust and an even bake, while the amylase-enhanced fermentation creates a bread that’s both aromatic and satisfying. The result is a loaf with a crisp exterior and a tender, airy interior—perfect for sandwiches, toast, or simply enjoying on its own.

This recipe is designed to be foolproof, with clear steps and timing to ensure success every time.

Whether you’re a home baker looking to experiment with fermentation or someone seeking a bread that’s easier on digestion, this amylase bread delivers. The technique is straightforward, but the results are anything but ordinary. Let’s get started on creating a loaf that’s as impressive as it is delicious.

Ingredients for amylase bread

Fermented flavor and digestible texture start with these 13 precise ingredients—no gluten grains needed.

The malt powder is non-negotiable here. Bob's Red Mill malt powder delivers consistent amylase activity, but Barley Malt Powder works equally well. For malted flour, use the same weight—King Arthur Malted Flour is a reliable choice. Yeast quality matters too: Red Star Active Dry Yeast is my go-to, but ensure it's fresh—yeast loses potency after 4 months in the fridge. The vital wheat gluten and xanthan gum create structure without gluten grains; Caputo or Bob's Red Mill brands are industry standards. Rice flour adds lightness, while the cornmeal creates that signature crust texture.

No malt powder? Diastatic malt powder is the next best option, though it requires precise measurement—half the amount of malt powder. Running low on instant vital wheat gluten? Substitute with 10% more all-purpose flour, though texture may vary. The honey can be swapped for maple syrup or agave, but keep the total liquid volume consistent. Olive oil alternatives include avocado oil or melted coconut oil, though flavor profiles differ. For a gluten-free adaptation, omit the vital wheat gluten entirely and increase the rice flour to 1 cup. Always weigh ingredients by volume for accuracy—digital kitchen scales are worth the investment for this recipe.

Malt powder and yeast should be stored in airtight containers in a cool, dark place—pantry or refrigerator for extended shelf life. The dough can be refrigerated for up to 24 hours before baking, allowing flavors to develop further. For longer storage, freeze the shaped loaf (unbaked) for up to 3 months3-5 days, wrapped in a clean kitchen towel to maintain moisture. Slice with a serrated knife for clean cuts, and always store leftovers in the fridge to prevent staling.

Step-by-step instructions for amylase bread

A precise fermentation process creates authentic sourdough flavor without gluten grains. Here's how to transform malt powder into a flavorful, textured loaf.

In a small bowl, combine the 0.5 oz malt powder with 1 cup of the 2.5 cups lukewarm water (110°F/43°C). Stir until completely dissolved, then let sit at room temperature for 12-16 hours. This activates the amylase enzymes that will later break down starches into fermentable sugars, creating that signature tang.

You'll notice the mixture becomes slightly syrupy as the enzymes work. The longer it sits within this temperature range, the more pronounced the fermentation flavor will be. If your kitchen is warm, aim for the shorter end of the time range to prevent over-fermentation.

In a large mixing bowl, combine the 4 cups all-purpose flour, 0.5 cup rice flour, 0.25 cup instant vital wheat gluten, 0.25 tsp xanthan gum, and 1.5 tsp salt. Make a well in the center and add the activated malt water mixture, 1 tbsp honey, 2 tsp olive oil, and the remaining 1.5 cups water. Mix with a dough whisk until no dry flour remains.

The dough will initially appear shaggy but will begin to come together as the gluten develops. This blend of flours creates both structure and a lighter crumb. Let the dough rest for 10 minutes while you prepare your yeast mixture in a separate bowl.

In a separate bowl, sprinkle the 0.25 oz active dry yeast over ½ cup of the 2.5 cups lukewarm water and let it dissolve for 5 minutes until foamy. Add this yeast mixture to your dough along with the 0.25 cup ice water. Mix thoroughly until the dough reaches a smooth, slightly sticky consistency.

Cover the bowl with a damp kitchen towel and let ferment at 75°F (24°C) for 4-6 hours, until the dough has nearly doubled in volume and shows bubbles along the surface. This controlled fermentation develops both flavor and proper gluten structure. If your kitchen is cooler, extend fermentation to 8 hours to ensure full development.

Lightly dust your work surface with 2 tbsp cornmeal and transfer the dough. Gently shape into a round boule by pulling the edges toward the center and tucking under. Place seam-side down on a parchment-lined baking sheet, brush lightly with 1 tbsp cornstarch mixed with 1 tbsp water, and cover again.

Let the shaped dough proof for 1-2 hours until it has risen 50-75% and springs back slowly when gently pressed. The cornstarch brush creates a subtle barrier that helps develop that characteristic bread crust. For best results, proof in a slightly humid environment to encourage proper oven spring.

Preheat your oven to 425°F (220°C) with a baking stone or inverted baking sheet inside for 45 minutes. Transfer the dough (still on parchment) to the hot stone and bake for 25 minutes. Reduce heat to 375°F (190°C) and bake for an additional 20-25 minutes until internal temperature reaches 205°F (96°C).

The bread is done when it develops a deep golden crust with crisp edges and a hollow sound when tapped on the bottom. The malt powder's enzymatic activity creates a subtle sweetness that develops fully during baking. Cool on a wire rack for at least 1 hour before slicing to allow the crumb to set properly.

Storing and reheating this amylase bread

Refrigerator Storage

Store your freshly baked amylase bread in an airtight container at room temperature for up to 2 days to preserve its freshness. For longer storage, transfer to the refrigerator where it’ll keep for 5-7 days.

Wrap the loaf in a clean kitchen towel or beeswax wrap to maintain moisture and prevent drying—this mimics the traditional bread storage method. I always store mine in a glass container with a tight lid to prevent staling. 🥖

Freezer Preservation

For extended storage, freeze your amylase bread by slicing it first (if you prefer pre-sliced portions) or freezing the whole loaf. Wrap tightly in plastic wrap followed by aluminum foil or place in a freezer bag with all air removed.

Label with the date—this bread freezes beautifully for up to 3 months. When ready to eat, thaw overnight in the fridge or reheat directly from frozen for 10-15 minutes at 350°F (175°C).

Reheating Methods

For the best texture, reheat bread slices in a toaster or toaster oven for 1-2 minutes until golden and crisp. If using an oven, wrap slices in foil and heat at 350°F (175°C) for 5-7 minutes.

For microwave reheating, place slices on a plate, cover with a damp paper towel, and heat on 50% power for 15-20 seconds—this prevents drying. The malt powder’s residual enzymes react slightly during reheating, enhancing that subtle sweetness. 🔥

Reviving Stale Bread

If your amylase bread loses its freshness, don’t toss it! Place slices in a baking dish, cover with water, and bake at 350°F (175°C) for 5-10 minutes until heated through. The steam will restore moisture and crispness.

Alternatively, sprinkle stale slices with water, cover with a plate, and microwave for 20 seconds—this works surprisingly well. The bread’s unique enzyme activity makes it more resilient to staling than traditional loaves.

Crust Refreshing

To revive the crust’s crispness, brush the surface with melted butter or olive oil and broil for 1-2 minutes until golden. For a stovetop method, heat a dry skillet over medium heat and toast slices until crispy on both sides.

This technique works especially well for sandwich bread—just be sure to keep an eye on it to avoid burning. The malt-enhanced crust responds beautifully to this treatment. ✨

Portioning Tips

Slice your amylase bread with a serrated knife for clean cuts and store slices in a single layer in an airtight container to prevent sticking. For sandwiches, wrap individual slices in parchment paper before storing in the fridge.

The bread’s lighter texture means it’s less prone to squishing than denser loaves, making it ideal for meal prep. Label containers with dates to track freshness—this bread stays fresh longer than most artisan varieties. 📅
