Sourdough sticky buns that are richer, more flavorful, and delightfully complex. While they may seem intimidating, making these sticky buns at home is easier than you think. Follow this step-by-step guide, and you’ll have a batch of bakery-worthy buns fresh from your oven, filling your kitchen with irresistible aromas.
Ingredients You’ll Need
Before you begin, gather all the ingredients. Quality makes a difference, especially when working with sourdough, cinnamon, and caramel.
Activate Your Sourdough Starter
The secret to the perfect tangy flavor in these sticky buns is an active sourdough starter.
Make sure your starter is bubbly and active, ideally fed 4–6 hours before baking. A lively starter will help the dough rise beautifully, adding both flavor and lightness.
Prepare the Dough
In a large mixing bowl, combine the sourdough starter, warm milk, melted butter, sugar, and egg. Stir until smooth.
Gradually add the flour and salt, mixing until a sticky dough forms.
Transfer to a lightly floured surface and knead for 8–10 minutes until the dough is elastic and soft. Sourdough dough may be slightly stickier than traditional dough—this is normal.
First Rise
Place the dough in a greased bowl and cover with a clean towel or plastic wrap. Let it rise at room temperature for 4–6 hours, or until it has roughly doubled in size.
The sourdough starter not only adds tang but also allows a slower, more flavorful fermentation. This rise develops both texture and taste.
Prepare the Caramel Topping
In a small saucepan over medium heat, melt butter, brown sugar, and honey or corn syrup together.
Stir constantly until the mixture is smooth and slightly thickened. Remove from heat and stir in vanilla extract. Pour the mixture evenly into a greased 9×13-inch baking pan. Sprinkle chopped nuts on top if desired.
Roll Out the Dough
Once the dough has risen, punch it down gently and transfer it to a lightly floured surface.
Roll it out into a rectangle, about 12×16 inches. Spread the softened butter over the dough, then evenly sprinkle the brown sugar and cinnamon mixture on top. This filling will melt during baking, creating the gooey, sweet swirls that make sticky buns irresistible.
Shape the Buns
Starting from the long edge, roll the dough tightly into a log. Slice the log into 12 equal pieces using a sharp knife or dental floss for a clean cut.
Place the buns cut-side down on top of the caramel mixture in your prepared pan. Leave a little space between each bun to allow expansion.
Second Rise
Cover the pan loosely and allow the buns to rise for 1–2 hours, or until slightly puffy.
This second rise ensures the buns are light and airy, rather than dense, and it helps them bake evenly.
Bake the Buns
Preheat your oven to 350°F (175°C). Bake the sticky buns for 25–30 minutes, or until golden brown and cooked through.
Keep an eye on them—overbaking can make the caramel sticky but slightly harden the top. Once done, remove the pan from the oven and let the buns cool for 5–10 minutes before inverting.
Invert and Serve
Place a large serving platter or cutting board over the pan and carefully flip it upside down.
The caramel topping will drizzle over the buns, coating each one in sticky sweetness. Serve warm for the best experience, but these buns also taste incredible at room temperature.
Storage and Reheating
Store leftover buns in an airtight container at room temperature for up to 2 days or in the fridge for up to a week.
Reheat gently in the microwave for 15–20 seconds or in a low oven to refresh the gooey caramel texture.
Tips for Perfect Sourdough Sticky Buns
- Use an active starter – the flavor and rise depend on it.
- Don’t rush the first rise – slow fermentation adds depth.
- Roll tightly but gently – keeps layers intact without squishing the dough.
- Caramel topping first – ensures each bun is coated in sweet, sticky goodness.
- Serve warm – sticky buns are always best enjoyed fresh from the oven.
Sourdough sticky buns combine the rich sweetness of traditional sticky buns with the subtle tang and complexity of sourdough.
With soft, airy dough, swirls of cinnamon sugar, and a luscious caramel topping, these buns are perfect for weekend breakfasts, holiday brunches, or special celebrations. Baking them may take a bit of time, but the reward is a batch of golden, sticky, melt-in-your-mouth buns that everyone will love.
