Sourdough Maple Bars

This post may contain affiliate links. Read our disclosure policy.

There’s just something about a classic maple bar that gets me every time. These Sourdough Maple Bars are pillowy soft, fried until golden, and dipped in a thick, buttery brown sugar maple glaze. They’re soft, fluffy, melt in your mouth and have all the nostalgic maple flavor that tastes like they’re straight from your favorite donut shop.

Tools You’ll Need:

1. Stand mixer (optional)- for kneading dough. You can mix the dough by hand but a stand mixer is easiest.
2. Medium sized pot- for making tangzhong and glaze.
3. Whisk- for mixing the tangzhong and glaze.
4. Kitchen scale (optional)– for accurate measuring, especially helpful with baking linked here.
5. Measuring cups and spoons- if not using a scale and for smaller ingredients.
6. Rolling pin- for rolling out donuts.
7. Pizza wheel or pastry cutter- for cutting out the donuts.
8. 12 7×4 parchment squares- This make frying the donuts so easy! I cut my own before hand.
9. Deep pot or Dutch oven– for frying donuts.
10. Frying thermometer– for keeping oil at 340–350°F. I strongly recommend using this tool to avoid burning I use this one linked here and love it.
11. Slotted spoon or spider- to flip donuts. The spider I use is linked here.
12. Chopsticks (optional)- helpful for flipping donuts. I like these reusable chopsticks linked here. I also used these to poke a hole in my donuts first to create a pocket for my filling.
13. Cooling rack + paper towels– for drying donuts after frying.
14. Tongs- for removing parchment from oil while frying.
15. Digital Thermometer (optional)- helps with assessing when tangzhong is done.
16. Wire rack– for draining excess glaze from donuts after glazing.

Gather Your Ingredients:

1. Whole milk– milk enriches this dough making it soft and tender. You’ll also use milk to make your tangzhong.
2. Egg- adds tenderness and structure to the dough working as a binder.
3. Sourdough starter- If you make this recipe 100% sourdough you’ll use your starter to feed a sweet levain, or you can make the discard option and add yeast. Any discard cold or fresh is fine.
4. Instant dry yeast (optional)- This is the leavening agent for the dough if you do the discard option, and speeds up the process! I love this Scratch Gold Yeast and always have it on hand. Please note instant dry yeast isn’t the same as active dry yeast which you have to bloom to activate. I’ll include an active dry yeast swap under FAQ’s.
5. Unsalted butter- enriches dough. You’ll also use this in the glaze.
6. White Sugar- sweetens the dough and cuts the tang of the starter with a sweet levain.
7. Sea salt- balances sweet and sour flavors.
8. Vanilla extract- for aromatic warmth and depth of flavor to dough.
9. All-purpose flour- I recommend AP flour over bread flour to create a more tender crumb. The egg and tangzhong will provide the structure in this recipe making bread flour unnecessary, but you can substitute for bread flour if needed.
10. Organic Coconut Oil- for frying donuts and achieving a crisp texture without a strong aftertaste. I highly recommend Carrington Organic coconut oil linked here. This container lasts me several batches when frying, and you just allow the oil to cool after frying and remove any excess bits before transferring left over oil to a glass jar. Coconut oil has a higher smoke point which is ideal for frying, has little to no aftertaste, and is more stable under high heat making it less likely to oxidize and form harmful free radicals.
11. Heavy Cream- Creates a smooth, shiny finish and helps thin the glaze.
12. Powdered sugar – to sweeten and thicken the maple glaze. Do not use granulated sugar as it wont dissolve properly.
13. Brown Sugar- this sweetens the glaze and adds depth to balance out the maple.
14. Maple Syrup– to sweeten and and give the glaze that classic maple flavor.
15. Maple Extract (optional)– to enhance the maple flavor in the glaze. This is optional, but really brings out the maple for maple lovers. I love this maple flavoring from Frontier Co-op linked here.

Instructions

Step 1: Make the Sweet Levain (Night Before)

To start your dough, you’ll want to mix a sweet levain the night before. If this sounds intimidating, it’s not! It’s literally just adding sugar to your starter. This curbs the tang of the sourdough for the perfect donut.

In a clean jar, mix your mother starter with the flour, water, and sugar. Give it a good stir, and allow it to rest at room temperature (optimally 73-75 degrees F). I like to mark the volume in my jar with a rubber band so it’s easy to asses the rise the next morning. When the sweet levain has doubled in size, it’s time to mix your donut dough.

Sourdough Discard Option: If you make this recipe with discard and yeast, skip this step.

Step 2: Make the Tangzhong

Before you get started on mixing your dough, you’ll make your tangzhong. Whisk milk and flour together in a small saucepan.

Cook the tangzhong over medium/low heat, stirring constantly, until it thickens into a paste that is similar to pudding (about 2–3 minutes). For precision, use your digital thermometer and heat to 148-155 F. Do not overheat, or your mixture will be too thick.

Scrape into a bowl immediately to prevent further cooking, cover, and let cool to room temperature before adding to your dough.

Prepare your dough while tangzhong cools.

Step 3: Mix the Dough

In a stand mixer fitted with a dough hook or large mixing bowl, add the whole milk, sweet levain, egg, sugar, vanilla, and all of the tangzhong. Whisk ingredients together quickly, it’s okay if it’s lumpy.

Sourdough Discard Option: If you’re making this recipe with discard and yeast, add the discard and instant yeast instead of the sweet levain to the wet ingredients and whisk in.

Add your flour and salt into your wet ingredients.

Mix on low until a shaggy dough forms, about 2-3 minutes. Scrape down bowl if needed. If using your hands, knead until you work dough together. This is a higher hydration dough, so be aware it will be sticky.

Once the dough has come together add the softened butter, a tablespoon at a time mixing each tablespoon in until adding the next. Use a dough scraper to scrape the edges of the bowl to make sure everything is getting mixed in.

Continue mixing on medium-low (speed 2–3) for 8–10 minutes, until dough is smooth, elastic, and tacky but not sticky. If mixing by hand knead dough until butter has fully incorporated and dough is smooth and tacky.

Mixing Notes: If kneading in a mixer or if dough is very wet when mixing by hand, add an additional 25 grams (3 Tablespoons) of flour and mix into dough. Make sure to work flour in completely and assess if you need more flour.

Do not add more than 50 grams of flour at this stage, or you will lose the high hydration of the dough and end up with a dense donut. If using a stand mixer, dough can become more warm and sticky and I have found kneading dough with my hand (perform a set of stretch and folds) for a minute after mixing in my stand mixer really helps bring the dough together.

Step 4: Bulk Fermentation

Stand mixer directions: perform one set of stretch and folds after 30 minutes to strengthen your dough.

Hand mixing directions: perform 3 sets of stretch and folds at 30 minute intervals at the beginning of bulk fermentation. After stretch and folds are completed, cover dough and allow to continue proofing.

Sourdough Discard Option: After the 20 minute rest, knead the dough by hand for a minute or two to get the dough even softer and to work the gluten. Once you’ve finished this kneading step, cover the bowl again.

Let the dough rise at 75–80°F until doubled in size, this takes about 5–6 hours. If your house is very cold, you can put dough in the oven with the light on for a warmer atmosphere. This proofing time is a general guide, this process may take longer the key is to assess when the dough has nearly doubled that’s when it’s ready.

Sourdough Discard Option: Allow the dough to rest about 1 1/2 hours at room temperature and the dough is ~75–90% risen. You don’t want this dough to proof double fully at this rising point. If the dough proofs sooner than the time I mentioned, shape it. You want to watch the dough to make sure it doesn’t overproof at this stage!

Overnight Fermentation: Once dough has finished rising, you can cover and transfer to the refrigerator overnight for a longer ferment or you can skip this step and go straight to making your donuts. I do find it to be easier to shape the donuts when the dough has been refrigerated but it isn’t necessary.

Step 5: Shape the Donuts

Flour your work surface. Turn out the dough on your work surface and flour the top and the rolling pin to avoid sticking. Flouring is key to a clean transfer, don’t skip it.

Roll the dough into a 12 × 10-inch rectangle, approximately ¾ inch thick. Trim the edges if needed to create a clean rectangle.

Cut the rectangle in half lengthwise to create two 5-inch wide rows. Cut each row crosswise into six 2-inch wide pieces. You should have 12 maple bars approximately 5 × 2 inches each.

Place each maple bar onto an individual square of parchment paper about 7×4 inches. This makes it easier to transfer the delicate proofed dough into the hot oil without deflating it. Transfer to baking sheets to proof.

Step 6: Final Proof

Cover bars loosely with plastic sprayed with cooking oil and let rise at room temperature for 1-2 hours, or until puffy and jiggly.

When poked gently with a fingertip, the dough should spring back slowly, not immediately. Because this dough has the tangzhong to provide stability to the dough, you can push your final proof a little longer to get a really airy donut. It’s better to give this step more time than less.

Sourdough Discard Option: The second rise will be faster if you used discard and yeast, allow the donuts to proof about 45 minutes to an hour and then fry them. Avoid over proofing or you’ll end up with air pockets.

Step 7: Fry the Donuts

Line a cooling rack with paper towels. Fit your candy thermometer into your deep pot. Transfer 3–4 cups of organic coconut oil to a deep pot or Dutch oven, and heat to 350-360°F on medium heat.

If the oil gets hotter than this, reduce the heat accordingly. Watch your temperatures very closely and adjust your heat as needed to avoid burning donuts.

When the oil is ready, transfer 2 donuts with parchment paper into oil (you can remove paper with tongs when it separates).

Fry each donut 30 seconds at a time per side, flipping donuts gently using chopsticks or a slotted spoon. I repeat this step a few times rotating donuts to avoid burning.

Remove after a 2-3 minutes with a slotted spoon or spider spoon and donuts are a golden brown. Remove and transfer to a rack lined with paper towels to cool.

Repeat this step until all donuts have been fried. Allow the donuts to cool while you prepare the maple glaze.

Step 8: Glaze the Donuts

Melt the butter in a small saucepan over medium low heat for the glaze. Add the dark brown sugar and maple syrup and stir until smooth.

Once the mixture reaches a gentle bubble, cook for about 2-3 minutes, stirring constantly, until the brown sugar is dissolved. It’s very important to make sure the brown sugar has fully melted or the glaze will be grainy.

Remove the glaze from the heat and allow it to cool for a few minutes; check and make sure the sugar has dissolved. If you see any gritty grains of sugar, transfer back to the stove and cook a few more minutes.

Make sure the glaze cools slightly before you proceed.

Whisk in the sifted powdered sugar (this is key to a smooth glaze to sift it), maple extract if you’re using it, vanilla, and salt.

This glaze will be really thick; add the heavy cream slowly and whisk it gently until it’s smooth and the desired consistency. You may need less or more cream so go slow when you’re adding it.

The glaze should fall from the whisk in a thick ribbon and slowly settle back into itself rather than running like a thin icing.

Dip the tops of the slightly warm maple bars into the warm glaze. Return them to the wire rack and allow the glaze to set before serving.

Note for icing: If the glaze starts to get too thick, gently warm for a minute on the stove and whisk. Resume glazing the donuts until all of them are topped.

Yields 12 donut bars
