Add all ingredients to a large bowl and mix until combined.
Let batter rest for 20 minutes at room temperature while your skillet or griddle heats.
To Ferment Batter Overnight:
In a large bowl, whisk together sourdough starter, milk, sugar, pumpkin spice, melted butter, and flour until smooth.
Cover and ferment at room temperature for up to 12 hours.
In the morning, add eggs, baking soda, baking powder, pumpkin puree, and salt. Stir to combine.
Rest for 20 minutes while heating your skillet.
Cooking:
Lightly grease your hot skillet. Pour ¼ cup batter for each pancake.
Cook on low until bubbles form on top and the bottom is golden. Flip and cook until golden on the other side, about 4 minutes per side.
Keep the heat moderate—pumpkin’s natural sugars can cause burning if it’s too hot.
Notes
Tips
Choose the right starter: For overnight fermentation, use active starter for fluffier pancakes. For same-day cooking, fresh discard works well, but flavor will be tangier.
Manage pumpkin puree moisture: If your puree is watery, drain it first. Too much moisture makes the batter thin; you can fix it by adding a little more flour.
Spice it right: Use pumpkin pie spice for classic flavor, or blend cinnamon, nutmeg, ginger, and cloves for more depth.
Add baking soda last: Mix baking soda in right before cooking. It reacts quickly with the acidic starter, and waiting helps maximize rise.
Mix gently: Overmixing leads to tough pancakes. A few lumps in the batter are perfectly fine.
Let the batter rest: A short 10–15 minute rest makes for lighter pancakes.
Mind your heat: Cook on medium to medium-low. Pumpkin’s sugars brown quickly, so slower cooking helps keep them fluffy inside without burning outside.
Flip with care: These pancakes can be a bit denser, so use a wide spatula for flipping.
Adjust thickness if needed: Too dense? Add a splash of milk or water. Too thin? Add flour one tablespoon at a time.
Dress them up: Try nuts, dried fruit, or whipped cream for a festive touch.
Storage
Short-Term (2–3 Days):
Cool completely to prevent sogginess.
Stack with parchment between pancakes and store in an airtight container in the fridge.
Freezer (2–3 Months):
Cool completely.
Separate pancakes with parchment, wrap tightly, and store in a freezer-safe bag or container.
Reheating:
From fridge: Microwave 20–30 seconds or heat in a skillet for 1 minute per side.
From freezer: Microwave 45–60 seconds or bake at 350°F (175°C) for 5–10 minutes.
