Why You Will Love This Recipe

Let me tell you what makes these different from a regular raspberry muffin. The sourdough starter adds a subtle tang that balances the sweetness of the raspberries perfectly. It also creates an incredibly tender crumb that you just cannot get from a standard quick bread.

These are not dense muffins. They are not tough muffins. Instead, they are light, fluffy, and domed on top. They are so good that I have a hard time eating just one. This sourdough discard recipe has become one of my absolute favorites and I think it will become one of yours too.

Sourdough Discard or Active Starter?

Good news — this recipe works with both! You can use sourdough starter discard from your refrigerator, or you can use a fed starter that is active and bubbly.

Using Active Starter

If you use an active sourdough starter, your muffins will have a slightly more pronounced sourdough flavor. You will also get a little extra lift from the active starter. Either way, the results are absolutely beautiful.

Using Discard

If you use sourdough starter discard, the flavor will be milder. However, the muffins will still turn out incredibly fluffy and delicious. If your discard has been sitting in the refrigerator for more than a week, give it a sniff first. It should smell pleasantly sour and tangy. If it smells off or unpleasant, toss it and use fresher discard instead.

Ingredient Notes

Whole milk and vinegar: These two ingredients create a homemade buttermilk. Together with the sourdough starter, they give these muffins their incredible rise and tender texture. Do not skip this step.

Sourdough starter: Use it cold from the refrigerator or at room temperature. Either works well here. The starter adds flavor and moisture. It also helps create that gorgeous tender crumb that makes sourdough muffin recipes so special.

Applesauce: The applesauce adds moisture without adding a lot of extra fat. It pairs beautifully with the sourdough flavor and the raspberries. Additionally, sour cream or Greek yogurt can be substituted in equal amounts for a richer muffin.

Flour: All-purpose flour gives you the best results here. No special flours are needed. The combination of 4½ cups of flour with one cup of sourdough starter gives you the perfect batter consistency.

Raspberries: Frozen raspberries are my first choice because they hold their shape better in the batter. Fresh raspberries work well too. However, handle them gently so they don’t break down and turn your batter pink.

Fun Variations to Try

• Add white chocolate chips for an incredible flavor combination
• Add a teaspoon of lemon zest or a splash of lemon juice for brightness
• Swap raspberries for blueberries to make sourdough blueberry muffins
• Try a mix of berries for your own sourdough berry muffins version

Equipment You Will Need

Nothing fancy is required here. First, grab a large mixing bowl and a rubber spatula. You will also need a measuring cup, a standard muffin tin, and paper liners or cooking spray. Finally, a cookie scoop makes filling your muffin cups much easier. A cooling rack is helpful for cooling the muffins quickly after baking.

How to Make Sourdough Raspberry Muffins

Makes approximately 24 muffins

Step 1: Bring Ingredients to Room Temperature

Pull your eggs and sourdough starter out of the refrigerator about 30 minutes before baking. Room temperature ingredients mix together more evenly. As a result, you get a better finished muffin with very little extra effort.

Step 2: Make Your Buttermilk

Combine the whole milk and white vinegar in a measuring cup. Stir and let it sit for 5 minutes. The milk will thicken and curdle slightly, and that is exactly what you want.

Step 3: Mix Your Wet Ingredients

In a large mixing bowl, combine the brown sugar, white sugar, applesauce, eggs, and vanilla extract. Next, add the sourdough starter and the buttermilk mixture. Stir until everything is smooth and well incorporated.

Step 4: Add Your Dry Ingredients

Add the flour, baking powder, baking soda, and salt to your wet ingredients. Stir until just combined, then stop. Do not overmix. Overmixing causes gluten formation and turns fluffy muffin batter into tough muffins. A few lumps are completely fine.

Step 5: Rest the Batter

Here is a sourdough tip that makes a real difference. Let your muffin batter rest for 10 to 15 minutes before scooping. This batter rest gives the starter time to work. As a result, you get a taller muffin top and a lighter crumb.

Step 6: Fold in the Raspberries

Gently fold in your raspberries using a rubber spatula. If you are using frozen raspberries, add them straight from the freezer at the very last second. This prevents them from bleeding into the batter and keeps your muffins looking gorgeous.

Step 7: Fill Your Muffin Tin

Line your muffin pans with paper liners or spray with cooking spray. Then use a cookie scoop to fill each muffin cup all the way to the top. Filling to the top is what gives you those beautiful domed muffin tops.

Step 8: Bake

Bake at 425 degrees F for 5 minutes. Then reduce the oven temperature to 350 degrees F and bake for another 16 to 18 minutes. Starting at a higher temperature creates that gorgeous rise before the outside sets. Your muffins are done when a toothpick inserted in the center comes out clean.

The Secret to Fluffy Sourdough Raspberry Muffins

Two things make these muffins extraordinary. First, do not overmix your batter. Stop stirring as soon as the dry streaks of flour disappear. Second, do not skip the batter rest. These two steps work together to give you light, fluffy muffins every single time.

---

Tips for the Best Results

Keep frozen raspberries frozen. Add them at the very last moment. Then work quickly to get the batter into the muffin tin before they start to thaw.

Don’t skip the batter rest. Even 10 minutes makes a noticeable difference in your muffin tops. Furthermore, use that time to preheat your oven and get your pans ready.

Fill cups to the top. I know this feels wrong if you have made muffins before. However, trust the process. This is what creates that gorgeous domed top.

Want a sweeter muffin? Simply add an extra quarter cup of white sugar to the batter. These are well balanced as written, but a little extra sugar never hurts.

Make a double batch. This recipe already makes 24 muffins. However, if you have the time, freeze half for later. Having homemade sourdough muffins in your freezer is never a bad idea.

How to Store Sourdough Raspberry Muffins

Once your muffins have cooled completely, store them in an airtight container at room temperature for up to three days. First, tuck a paper towel in the bottom of the container to absorb extra moisture. This keeps the bottoms from getting soggy.

Freezing Instructions

For longer storage, place cooled muffins in a freezer bag. They will keep well for up to three months. To reheat, pop a frozen muffin in the microwave for 30 to 45 seconds. It will taste like it just came out of the oven, which is why I always freeze half the batch.

Can I Make Sourdough Raspberry Muffins Ahead of Time?

Yes, and they are actually even better on day two. The sourdough flavor develops further overnight, which makes them taste even more incredible. Additionally, you can mix your dry and wet ingredients separately the night before. Then combine them, rest the batter, fold in your raspberries, and bake fresh in the morning.

Frequently Asked Questions

Can I use active starter instead of discard? Absolutely. An active starter gives a slightly stronger sourdough flavor and extra lift. Both work beautifully here.

Can I use Greek yogurt or sour cream instead of applesauce? Yes, substitute in equal amounts. As a result, the muffins will be a little richer and the sourdough flavor will come through more strongly.

Can I make jumbo muffins? Yes! Simply use a jumbo muffin pan and increase baking time by about 5 minutes. Check for doneness with a toothpick in the center of the largest muffin.

Can I add lemon? Please do. A teaspoon of lemon zest or a tablespoon of lemon juice in the wet ingredients is incredible with the raspberries. Orange zest is also wonderful if you want to try something different next time.

What if I don’t have a full cup of discard? No problem. Simply make up the difference with Greek yogurt or sour cream. You will still get beautiful results.
