How to Make Sourdough Twinkies
-
Preheat oven: Start by setting your oven to 350°F. Lightly grease a Twinkie cake pan and set it aside, preparing for those delightful treats.
-
Mix dry ingredients: In a large bowl, whisk together 105 grams of all-purpose flour, 150 grams of sugar, baking powder, and salt until fully combined. This dry mixture will be the backbone of your cake.
-
Separate eggs: Carefully separate the egg yolks and egg whites into two separate bowls. This allows you to create the airy texture crucial for your Sourdough Twinkies.
-
Combine wet ingredients: In a large glass measuring cup, mix the sourdough discard, 60 grams of neutral oil, 3 egg yolks, and 4 grams of vanilla extract. Pour this wet mixture into the dry ingredients, stirring until smooth and well blended.
-
Beat egg whites: In the bowl of a stand mixer with the whisk attachment, beat the egg whites and 3 grams of cream of tartar on high speed until soft peaks form; this should take about 1-2 minutes.
-
Add sugar: Lower the mixer speed to low and slowly pour in 50 grams of sugar. Increase the speed back to high and beat until stiff peaks form, which will take an additional 1-2 minutes.
-
Fold together: Gently fold a third of the whipped egg whites into the cake batter to loosen it up. Then, carefully fold in the remaining egg whites until just combined, ensuring not to deflate all that airiness.
-
Pipe batter: Scoop the batter into a large pastry bag fitted with a large pastry tip. Pipe the batter into the prepared baking pan, filling it about two-thirds full.
-
Bake: Place the pan in the oven and bake for 15-20 minutes or until a toothpick inserted comes out clean and the Twinkies are golden brown. Let them cool completely in the pan before filling.
-
Make filling: For the filling, use a stand mixer with the whisk attachment to whip the room temperature butter on medium-high speed for 2-3 minutes until light and creamy.
-
Add powdered sugar: Lower the mixer speed to medium-low and gradually add 100 grams of powdered sugar. Once fully combined, add 2 grams of vanilla extract, heavy cream, and a pinch of salt, mixing until combined and smooth.
-
Inject filling: Fit a large pastry bag with a medium piping tip. Fill it with your delicious frosting and inject it into the bottom of each Twinkie until they are filled to your liking.
Optional: Dust with a light sprinkle of powdered sugar for an extra touch.

Make Ahead Options
These Sourdough Twinkies are perfect for meal prep enthusiasts looking to save time on busy days! You can prepare the cake portion up to 24 hours in advance by baking them and allowing them to cool completely before storing them in an airtight container in the refrigerator. The filling can also be whipped ahead and kept in the fridge for up to 3 days; just ensure it’s well-covered to maintain its creamy texture. When you’re ready to serve, simply fill the Twinkies with the chilled frosting and enjoy these delightful treats, which will be just as delicious as freshly made!
Expert Tips for Sourdough Twinkies
- Use fresh ingredients: Ensure your baking powder and sourdough discard are fresh for the best rise and flavor in your Sourdough Twinkies.
- Egg separation: Be gentle when separating egg whites and yolks; any yolk in the whites can prevent them from whipping to stiff peaks.
- Room temperature butter: Make sure your unsalted butter is at room temperature before whipping to achieve a smooth filling.
- Don’t over-mix: When folding in the egg whites, do so gently to maintain the airy structure, which is key to the Twinkie’s light texture.
- Cool before filling: Allow the Twinkies to cool completely before injecting the filling to prevent the frosting from melting.
- Flavor variations: Feel free to experiment with the filling by adding flavors like almond extract or citrus zest for a unique twist!
Storage Tips for Sourdough Twinkies
Room Temperature: Store leftover Sourdough Twinkies in an airtight container at room temperature for up to 3 days to keep them fresh and soft.
Fridge: If you prefer your Twinkies chilled, place them in the fridge for up to a week in an airtight container. Just allow them to come to room temperature before serving for optimal flavor.
Freezer: Freeze Sourdough Twinkies individually wrapped in plastic wrap and then placed in a zip-top bag for up to 2 months. Thaw at room temperature before indulging.
Reheating: For a warm treat, gently microwave a Twinkie for 10-15 seconds; this will make the filling extra creamy and the cake delightful.

Sourdough Twinkies Recipe FAQs
What type of sourdough discard should I use?
Absolutely! Use any active sourdough discard that you’ve got on hand. The discard can vary in tanginess, so feel free to experiment with what you have. Just ensure it’s not too old—if it’s developed a dark color or off smell, it’s time to toss it!
How should I store leftover Sourdough Twinkies?
To keep your Sourdough Twinkies fresh, store them in an airtight container at room temperature for up to 3 days. If you’re like me and prefer a chilled treat, place them in the fridge where they will last for about a week. Just allow them to come to room temperature before enjoying for the best flavor!
Can I freeze Sourdough Twinkies?
Certainly! To freeze your Sourdough Twinkies, wrap each one individually in plastic wrap and then place them in a zip-top bag. They can be frozen for up to 2 months. When you’re ready to enjoy them, simply thaw them at room temperature or warm them up in the microwave for about 10-15 seconds for a cozy treat.
What can I do if my egg whites don’t whip to stiff peaks?
Very! If your egg whites aren’t reaching stiff peaks, it could be due to the presence of fat or yolk in the bowl. Make sure your mixing bowl and whisk are completely dry and free from any grease. If you notice the whites starting to foam but not stiffening, try adding a sprinkle of cream of tartar—this can help stabilize them!
Are Sourdough Twinkies suitable for people with allergies?
While these Sourdough Twinkies contain common allergens like eggs and gluten from all-purpose flour, you can certainly modify them. For a gluten-free version, consider using a 1:1 gluten-free flour blend. If someone has egg allergies, you might explore egg replacement options like flaxseed or chia eggs, though the texture may vary.
How long can I keep the filling mixture?
You can keep any remaining filling mixture in the refrigerator for up to a week in an airtight container. When you’re ready to use it again, just give it a good stir—if it thickened up too much, a splash of heavy cream can help restore it to the desired consistency. Enjoy your Sourdough Twinkies!
