🛒 Ingredients for DIY Buttermilk Powder
- 2 cups full-fat cultured buttermilk (store-bought or homemade)
Note: Low-fat or lemon-vinegar “quick buttermilk” will not work for this recipe.
👩🍳 Step-by-Step Directions
Step 1: Pour the Buttermilk
Pour a thin, even layer of cultured buttermilk onto a parchment-lined dehydrator tray or fruit leather sheet.
Step 2: Dehydrate
Dry at 130°F–135°F for 10–12 hours, or until brittle and flaky. It should snap when bent.
Step 3: Cool and Break
Let the buttermilk flakes cool completely, then break them into small chunks.
Step 4: Grind to Powder
Pulse the flakes in a spice grinder, food processor, or blender until a fine powder forms.
Step 5: Store It
Store in an airtight container in a cool pantry, fridge, or freezer. Use a silica pack or mesh bag of rice to prevent clumping.

🔄 Buttermilk Powder Substitutes (Shelf-Stable)
If you’re out of buttermilk powder and need a dry, shelf-stable alternative for spice blends or baking mixes, try one of these:
- 🧂 Dry Yogurt Powder: A 1:1 substitute in most recipes. Offers tanginess and creaminess similar to buttermilk powder. Great for spice mixes and dressings.
- 🥛 Powdered Milk + Citric Acid: Combine 1 tablespoon nonfat dry milk powder with 1/8 teaspoon citric acid to replace 1 tablespoon buttermilk powder. Works well in baking mixes and ranch blends.
- 🍶 Sour Cream Powder: Slightly richer flavor than buttermilk powder but works as a substitute in dips, seasoning blends, and dressings. Use a 1:1 ratio.
- 🧁 Cream Cheese Powder (in dips): For creamy ranch-style dip mixes, you can replace buttermilk powder with cream cheese powder + a pinch of citric acid for tang. Best in wet applications.
Note: These options are shelf-stable and ideal for dry mixes like ranch seasoning, Fiesta dip, or pancake mix. Adjust acidity (with citric acid or vinegar powder) if your substitute lacks tang.
Perfect for homemade spice mixes like this Copycat Fiesta Ranch Mix or classic buttermilk ranch dressing.

Does it taste like store-bought buttermilk powder?

Can I make it in the oven?
Only if your oven has a warming or proof setting under 140°F. Otherwise, it may cook rather than dehydrate.
