Easily Make Powdered Sugar Using A Coffee Grinder

Quick answer

• A coffee grinder is an effective tool for transforming granulated sugar into a fine, powdered consistency.
• Ensure your grinder is clean and completely dry before you begin.
• Start with granulated sugar and add it to the grinder in small batches.
• Grind in short bursts, checking the consistency frequently.
• Add a small amount of cornstarch (about 1 teaspoon per cup of sugar) to prevent clumping.
• Sift the powdered sugar after grinding for an even finer texture.

Who this is for

• Home bakers who need powdered sugar in a pinch and don’t have any on hand.
• Individuals looking for a cost-effective way to make their own powdered sugar.
• Anyone with a dedicated coffee grinder (or a very thoroughly cleaned one) who wants to try a simple DIY kitchen hack.

What to check first

Brewer type and filter type

While this article is about making powdered sugar, not brewing coffee, it’s important to note that the tool you use matters. For making powdered sugar, you’ll need a grinder. If you’re using a coffee grinder, ensure it’s designed for grinding beans. Blade grinders are generally more suitable for this task than burr grinders, as burr grinders can get clogged with fine powders. The filter type is irrelevant for making powdered sugar.

If you’re looking for a dedicated tool for this and other kitchen tasks, a good spice grinder can be a worthwhile investment.

Water quality and temperature

For making powdered sugar, water quality and temperature are not directly relevant to the grinding process itself. However, if you plan to use your homemade powdered sugar in a recipe that requires water, then using filtered water and the appropriate temperature for that recipe will be important for the final outcome of your baking.

Grind size and coffee freshness

When making powdered sugar, the “grind size” is the very thing you are trying to control. You want to achieve a very fine powder. Coffee freshness is not a factor in making powdered sugar.

Coffee-to-water ratio

The concept of a coffee-to-water ratio does not apply to making powdered sugar. You are working with granulated sugar and processing it into a powder, not brewing a beverage.

Cleanliness/descale status

This is perhaps the most critical step when repurposing a coffee grinder. For making powdered sugar, your grinder must be impeccably clean and completely dry. Any residual coffee grounds, oils, or moisture can impart unwanted flavors and textures to your powdered sugar, potentially ruining your baking project. Ensure all parts of the grinder are free from any coffee residue.

Step-by-step (how to make powdered sugar with a coffee grinder)

1. Ensure your grinder is clean and dry.

• What “good” looks like: The inside of your grinder is free of any coffee grounds, oils, or moisture.
• Common mistake: Using a grinder that hasn’t been thoroughly cleaned, leading to coffee-flavored powdered sugar.
• How to avoid it: Dedicate a grinder specifically for this purpose, or spend extra time cleaning and drying your existing grinder.

2. Add granulated sugar to the grinder.

• What “good” looks like: A moderate amount of granulated sugar is in the grinder’s chamber, not exceeding its capacity.
• Common mistake: Overfilling the grinder, which can lead to uneven grinding and potential motor strain.
• How to avoid it: Work in small batches, filling the grinder no more than halfway.

3. Add a small amount of cornstarch (optional but recommended).

• What “good” looks like: Approximately 1 teaspoon of cornstarch per cup of granulated sugar is added. This helps prevent clumping.
• Common mistake: Forgetting to add cornstarch, resulting in powdered sugar that may clump easily.
• How to avoid it: Measure out your cornstarch before you start grinding.

4. Secure the lid tightly.

• What “good” looks like: The lid is firmly in place, preventing any sugar dust from escaping during grinding.
• Common mistake: Not securing the lid properly, leading to a powdery mess.
• How to avoid it: Double-check that the lid clicks or locks into place.

5. Grind in short bursts.

• What “good” looks like: The grinder operates for a few seconds at a time, with pauses in between.
• Common mistake: Running the grinder continuously, which can overheat the motor and produce a less fine powder.
• How to avoid it: Pulse the grinder for 5-10 seconds, then let it rest for a moment.

6. Check the consistency.

• What “good” looks like: You can see the sugar becoming finer with each burst.
• Common mistake: Grinding for too long without checking, potentially over-processing.
• How to avoid it: Open the lid carefully after a few bursts to feel the texture between your fingers.

7. Continue grinding until powdered.

• What “good” looks like: The sugar has a fine, powdery texture, similar to store-bought powdered sugar.
• Common mistake: Stopping too soon, leaving a gritty texture.
• How to avoid it: Keep grinding in short bursts until the desired fineness is achieved.

8. Empty the grinder.

• What “good” looks like: The powdered sugar is carefully transferred from the grinder to a clean bowl or container.
• Common mistake: Tipping the grinder too quickly, causing a cloud of powdered sugar.
• How to avoid it: Gently tap the grinder as you pour, or use a small brush to collect any remaining powder.

9. Sift the powdered sugar (optional but recommended).

• What “good” looks like: The powdered sugar passes through a fine-mesh sieve, creating an even smoother consistency.
• Common mistake: Skipping this step, resulting in slightly coarser powdered sugar.
• How to avoid it: Use a sieve or sifter over a clean bowl.

10. Store properly.

• What “good” looks like: The powdered sugar is stored in an airtight container in a cool, dry place.
• Common mistake: Leaving it exposed to moisture, which can cause it to clump.
• How to avoid it: Ensure the container is sealed tightly.

Common mistakes (and what happens if you ignore them)

Decision rules (simple if/then)

• If your grinder smells like coffee, then do not use it for powdered sugar because residual oils will taint the flavor.
• If you are making a large batch, then plan to work in multiple small batches because overfilling can damage your grinder.
• If you want to prevent clumping, then add cornstarch because it acts as an anti-caking agent.
• If you see sugar dust escaping, then stop grinding immediately and secure the lid because it’s a safety hazard and creates a mess.
• If the grinder motor feels hot, then stop grinding and let it cool because continuous operation can cause overheating.
• If the sugar still feels gritty, then continue grinding in short bursts because it needs more processing time.
• If you want the smoothest possible texture, then sift the powdered sugar because it removes any remaining small lumps.
• If you’re storing the powdered sugar for later, then ensure the container is airtight because moisture will cause it to clump.
• If you have a burr grinder, then be extra cautious about clogging and clean it immediately after use because fine powders can be difficult to remove.
• If you are unsure about the cleanliness of your grinder, then it’s best to use a different one or purchase store-bought powdered sugar because a contaminated batch is unusable.

FAQ

Can I use any type of sugar?

You should use standard granulated sugar for the best results. Other types of sugar, like brown sugar or turbinado sugar, have too many impurities or molasses to grind into a fine powder effectively.

How much powdered sugar can I make at once?

It depends on the size of your grinder. It’s best to work in small batches, filling the grinder no more than halfway, to ensure even grinding and prevent motor strain.

Will my powdered sugar taste like coffee?

It might, if your grinder isn’t perfectly clean. Residual coffee oils are the main culprit. Dedicating a grinder solely for spices and sugars, or cleaning your coffee grinder meticulously, is key.

How fine will the powdered sugar be?

With a good blade grinder and sufficient processing time, you can achieve a consistency very close to store-bought powdered sugar. Sifting will further refine it.

What if my powdered sugar clumps after storing?

This usually happens due to moisture. Ensure your powdered sugar is completely dry after grinding and stored in an airtight container in a cool, dry place. Adding cornstarch during grinding also helps.

Can I use this homemade powdered sugar for frosting?

Yes, absolutely. As long as it’s ground to a fine powder and doesn’t have any lingering coffee flavor, it will work perfectly in frostings, icings, and other baked goods.

How long does homemade powdered sugar last?

When stored properly in an airtight container in a cool, dry place, homemade powdered sugar can last for several months, similar to store-bought versions.
