Homemade Baking Powder Recipe

Introduction

Every baker has experienced that moment of panic: you’re halfway through mixing a batch of muffins or a beautiful cake batter when you suddenly realize you’re out of baking powder. It’s a tiny ingredient with a massive job, and without it, most baked goods simply won’t rise properly. But here’s the good news—running out of baking powder doesn’t have to mean stopping your baking plans. With just a couple of everyday pantry staples, you can whip up your own homemade baking powder in minutes.

This Homemade Baking Powder Recipe is incredibly straightforward, wonderfully reliable, and a true pantry lifesaver. Whether you’re baking frequently or you’re someone who likes to be prepared with homemade staples, this recipe ensures you’ll never have to abandon a baking project again. With only baking soda, cream of tartar, and an optional starch for long-term storage, you get a perfectly functional leavening agent that mirrors the performance of store-bought versions.

This recipe is especially valuable for anyone who prefers to avoid additives found in some commercial baking powders, or for gluten-free, grain-free, or paleo bakers looking for a clean, customizable alternative. You can make just enough for a single recipe or prepare a larger batch to keep on hand for future bakes.

If you’ve ever wondered whether homemade baking powder actually works—the answer is yes. It works beautifully. And once you know how easy it is, you may never rely solely on store-bought again.

Ingredients Breakdown

Below are the exact ingredients you provided, with no changes.

Yield: 1 tablespoon

Prep Time: 5 minutes
Total Time: 5 minutes

Ingredients

• 1 tsp baking soda
• 2 tsp cream of tartar
• 1 tsp cornstarch (optional for storage)

Large Batch (Makes about 1 Cup)

• ¼ cup baking soda
• ½ cup cream of tartar
• ¼ cup cornstarch (optional but recommended for storage)

Ingredient Notes

Baking soda:
Commonly sold in bulk or boxed form, baking soda acts as the base that reacts with cream of tartar to create lift in baked goods. You’ll find it in the baking aisle of most grocery stores.

Cream of tartar:
This acidic powder is essential for activating the baking soda. Typically found in the spice section, cream of tartar is what turns baking soda into a usable leavening blend.

Cornstarch or arrowroot:
This ingredient helps keep the mixture dry and clump-free, making it ideal for storage. It is optional for small, immediate-use batches. Both cornstarch and arrowroot are located in the baking or gluten-free aisle.

Additions

• Arrowroot powder: A great alternative to cornstarch if you prefer a grain-free or paleo-friendly version.
• Dried lemon zest: A pinch can add a gentle citrus note, especially lovely in light cakes or muffins.

Substitutions

• Arrowroot for cornstarch: Swap at a 1:1 ratio if avoiding corn.
• Skip the starch entirely: If making a very small batch for immediate use, you can omit the starch.

Serving Size

The base recipe yields 1 tablespoon of homemade baking powder, which is enough for many standard baking recipes. Larger batches store beautifully when kept dry and airtight.

Tools & Equipment Needed

To make this recipe successfully, you’ll only need a few basic kitchen tools:

• Measuring spoons or measuring cups (for the large batch)
• A small mixing bowl
• A whisk or small spoon for mixing
• A fine-mesh sieve (optional but helpful for preventing clumps)
• Airtight glass jar or container for storage
• Label and marker for noting the preparation date

No special equipment or appliances are required, making this one of the most accessible DIY staples you can prepare at home.

Step-by-Step Instructions

Below are the exact instructions you provided, expanded with context for clarity but without changing the steps themselves.

1. Combine the ingredients.
   Add the baking soda and cream of tartar to a small bowl. If you’re using cornstarch (or arrowroot), add it as well.
2. Whisk thoroughly.
   Whisk all ingredients together until fully combined. This ensures the leavening power is evenly distributed and prevents uneven rising in baked goods.
3. Store the mixture.
   Transfer the mixture to a glass jar or an airtight container with a tight-fitting lid. Make sure the container is completely dry.
4. Label your container.
   Label and date the jar so you know when it was made and can track freshness.

These steps apply to both small and large batches. Once mixed, your baking powder is ready to use immediately.

Tips & Variations

Dietary Adjustments

• Gluten-free: Use arrowroot or cornstarch—both are naturally gluten-free.
• Grain-free or paleo: Swap cornstarch for arrowroot.
• Corn-free: Arrowroot is an ideal substitute for cornstarch.

Adjusting for Freshness

If your homemade baking powder has been stored for a few weeks, test it before using (see the Freshness Test Tip below).

Seasonal Substitutions

• For spring and summer baking, add a hint of dried lemon zest.
• For autumn bakes, a tiny pinch of cinnamon can add warmth.

Pantry Substitutions

• Arrowroot can replace cornstarch at a 1:1 ratio.
• Omit cornstarch entirely if you are making the baking powder for immediate use.

Freshness Test Tip

To ensure your homemade baking powder is active:

1. Add ½ teaspoon of baking powder to ¼ cup warm water.
2. If it bubbles and fizzes immediately, it’s still good.
3. If not, it’s time to mix a fresh batch.

This test is especially useful for large batches stored for longer than a few weeks.

Flavor Profile & Pairings

While baking powder isn’t something you taste directly, its contribution to baked goods is essential. It brings:

• Lift and lightness to cakes, muffins, biscuits, and quick breads.
• A tender crumb in pancakes and waffles.
• Softer texture in cookies and scones.

Pairing ideas are omitted per your request (no drink pairings).

Ingredient Spotlight

Cream of Tartar

Cream of tartar is a byproduct of wine fermentation and a powerful acid used to stabilize and activate baking soda. When paired with baking soda, it creates the leavening reaction necessary for baked goods to rise.

How to choose:
Select a fresh, unopened bottle from the spice section.

How to store:
Keep in a dry cupboard away from moisture.

How to use:
Always whisk thoroughly to ensure even distribution.

Baking Soda

A common household staple, baking soda is essential for creating lift in baked goods when paired with an acid.

How to select:
Any brand works well; freshness is key.

How to test:
Add a little vinegar—if it fizzes, it’s active.

Pro Cooking Tips

• Always whisk thoroughly to prevent pockets of baking soda.
• Use a dry spoon each time you scoop from the jar.
• Never store homemade baking powder above the stove or near heat.
• For best results, make only a month’s worth at a time.
• Sift the mixture if you notice clumps.
• Keep away from humidity—moisture will deactivate it.

Storage & Freezing Guide

Storing Homemade Baking Powder

• Keep in an airtight glass jar.
• Store in a cool, dark cabinet.
• Avoid moisture at all costs.
• Add cornstarch or arrowroot when storing long term.

Freezing

Do not freeze baking powder. Moisture from the freezer environment can deactivate it.

Shelf Life

Expect 4–8 weeks of optimal freshness when stored properly.
