Malt Powder: Types, Uses, Benefits, Baking Tips

Malt powder is one of the most versatile ingredients in baking and beverage-making, yet many home cooks and even professional bakers still misunderstand how it works. Whether you’re making artisan bread, classic bagels, rich malted milkshakes, or flavor-packed cookies, understanding malt powder and the difference between diastatic malt powder and non-diastatic malt powder can dramatically improve your results.

This comprehensive guide explains what malt powder is, how it’s made, the best ways to use it, why bakers rely on barley malt powder, and how it compares to malted milk powder, malt extract, and barley malt syrup.

What Is Malt Powder?

Malt powder is a finely ground product made from malted grains, most commonly malted barley. The grain is soaked, allowed to germinate (sprout), and then dried and ground into powder. This process develops natural enzymes and complex flavors, creating a lightly sweet, toasty, caramel-like ingredient used in both baking and beverages.

Popular variations include:

• Barley malt powder

• Diastatic malt powder (enzyme-active)

• Non-diastatic malt powder (enzyme-inactive)

• Malted milk powder (contains milk solids + malt)

• Malt flour (similar but milled differently)

How Malt Powder Is Made

The production of malt powder involves:

1. Soaking (Steeping)

Grains absorb moisture to activate germination.

2. Germination (Malting)

Natural enzymes, especially amylase, develop.

3. Kilning (Drying)

The grain is dried at controlled temperatures to preserve (or deactivate) enzymes, depending on whether it will become diastatic or non-diastatic malt powder.

4. Milling

The dried malt is ground into fine powder or malt flour.

Types of Malt Powder

1. Diastatic Malt Powder (Diastatic Malt Flour)

This is an enzyme-active product rich in natural amylase.

Functions:

• Breaks starches into sugars

• Feeds yeast → stronger fermentation

• Improves crust color

• Enhances oven spring

• Softens crumb texture

Best for:

Bread, baguettes, pretzels, pizza dough, sourdough, croissants

2. Non-Diastatic Malt Powder

This type has inactive enzymes, offering only flavor, aroma, and color.

Benefits:

• Adds deep malt flavor

• Promotes browning

• Enhances aroma

• Boosts Maillard reaction

Best for:

Cookies, brownies, cakes, pancakes, ice cream, milkshakes

3. Malted Milk Powder

A blend of:

• Malted barley

• Wheat flour

• Milk solids

• Sometimes sugar

Used for malted milkshakes, drinks, desserts, and nostalgic flavors like Whoppers/Maltesers.

4. Dark / Roasted Malt Powder

Highly roasted malt with intense caramel and coffee-like flavors.

Great for:

• Dark breads

• Chocolate cookies

• Craft beer

• Desserts needing deep color

Milk Powder: Uses, Nutrition & How to Choose

Malt Powder in Baking

Why Bakers Use Malt Powder

Diastatic malt powder is considered a secret weapon in artisan baking because it improves:

• Dough fermentation

• Crumb softness

• Crust color

• Rise and oven spring

• Shelf life

Recommended usage

• 0.25% - 2% of total flour weight for diastatic malt

• 1-3 tbsp per batch for non-diastatic malt for flavor

Malt Powder in Drinks & Desserts

Malt powder gives beverages and desserts their iconic old-fashioned flavor.

Popular uses:

• Malted milkshakes

• Malted chocolate drinks

• Ice cream

• Pancakes & waffles

• Cookies and brownies

• Coffee drinks & lattes

• Dessert sauces and caramel

Malt Powder Substitutes

When you’re out of malt powder, use:

Best substitutes:

• Barley malt syrup

• Malt extract powder

• Non-diastatic malt (for flavor)

• Diastatic malt (for enzymatic effects)

• Brown sugar or molasses (partial flavor only)

Is Malt Powder Gluten-Free?

No.

Most malt powders are made from barley, which contains gluten.

Malted milk powder also contains wheat flour → NOT suitable for gluten-free or celiac diets.

Nutrition of Malt Powder

Typical nutrients include:

• Natural sugars (maltose)

• Carbohydrates

• Enzymes (if diastatic)

• Small amounts of minerals and vitamins

• Malted milk powder contains protein, calcium, and lactose

Where to Buy Malt Powder

You can purchase diastatic malt powder and non-diastatic malt powder from:

• Baking supply stores

• Artisan bread shops

• Online retailers

• Specialty grocery stores

How to Store Malt Powder

• Keep airtight

• Store in a cool, dry place

• Avoid moisture and heat

• Diastatic malt should be used within 6–12 months for enzyme freshness

Troubleshooting Malt Powder in Recipes

FAQs

1. What is malt powder used for?

Malt powder is used to enhance bread fermentation, add flavor and color, and create rich, malty beverages and desserts.

2. What’s the difference between malt powder and malted milk powder?

Malt powder = just malted grain.

Malted milk powder = malt + milk solids + sometimes sugar.

3. Is malt powder the same as malt flour?

They are similar, but malt flour is often milled more like grain flour, whereas malt powder is finer and used more commonly in baking formulas.

4. How much malt powder should I add to bread?

Use 0.25%–2% of flour weight for diastatic malt; use more for non-diastatic if adding only flavor.

5. Is malt powder gluten-free?

No, most malt powders contain gluten because they are made from barley or wheat.

6. Can I use malted milk powder in bread?

Yes, but it adjusts sweetness and moisture. It does not replace diastatic malt for enzymatic activity.
