What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, making it easy to pull together on short notice. If you’re new to sourdough discard recipes, don’t worry—it’s very forgiving, and substitutions are easy.

• Sourdough Discard (about 1 cup / 240 ml) – The star ingredient! Use your regular discard; no need to feed it first.
• All-Purpose Flour (1 ½ cups / 190 g) – For the batter’s structure. You can swap for almond flour for a gluten-free twist, but texture will vary.
• Granulated Sugar (¾ cup / 150 g) – Sweetens the batter and cinnamon filling.
• Baking Powder (1 tablespoon) – Helps the casserole rise and stay fluffy.
• Baking Soda (½ teaspoon) – Works with the sourdough’s acidity for lift.
• Salt (¼ teaspoon) – Balances sweetness.
• Milk (1 cup / 240 ml) – Whole milk preferred for richness, but any milk or dairy-free alternative works.
• Large Eggs (2, room temperature) – Binds ingredients and adds moisture.
• Unsalted Butter (6 tablespoons / 85 g, melted) – Adds richness to the batter and filling.
• Cinnamon (3 tablespoons) – The signature spice; use fresh ground for best aroma.
• Brown Sugar (½ cup / 100 g) – For the cinnamon swirl to create that gooey, caramelized layer.
• Cream Cheese (4 ounces / 115 g, softened) – For the luscious glaze topping.
• Powdered Sugar (1 cup / 120 g) – Sweetens the glaze.
• Vanilla Extract (1 teaspoon) – Enhances the glaze’s flavor.
• Milk or Cream (1-2 tablespoons) – To thin the glaze to perfect drizzling consistency.

For best results, I recommend using a trusted brand like King Arthur for flour and a high-quality cinnamon like McCormick. If you want a seasonal twist, swap the cinnamon for pumpkin pie spice in fall—just as comforting but with a little extra warmth. And if cream cheese isn’t your thing, try a dairy-free cream cheese alternative for a similar glaze texture.

Equipment Needed

• Baking Dish: An 8×8 inch (20×20 cm) square or similar-sized casserole dish works perfectly. Glass or ceramic is ideal for even heat distribution.
• Mixing Bowls: At least two—one for dry ingredients, one for wet. I find glass bowls easiest to clean and monitor mixing.
• Whisk and Spatula: For mixing batter and folding in ingredients without overworking.
• Measuring Cups and Spoons: Precision helps with rise and texture, especially with baking powder and soda.
• Electric Mixer (Optional): Helpful for whipping the cream cheese glaze smooth, but a hand whisk works fine with a bit more elbow grease.
• Oven Thermometer (Optional): To keep your oven accurate—essential for baking success, especially with casseroles.

If you don’t have an 8×8 dish, a 9×9 or even a round pie dish can work; just adjust baking time slightly. When I first made this, I used a smaller dish and the edges got extra crispy—delicious, but keep an eye on it. For glazing, a small offset spatula or even a spoon works well to drizzle the cream cheese glaze evenly.

Preparation Method

1. Preheat your oven to 350°F (175°C). Grease your 8×8 inch (20×20 cm) casserole dish with butter or nonstick spray. This prevents sticking and helps with even browning. (Time: 5 minutes)
2. In a large bowl, combine the dry ingredients: 1 ½ cups (190 g) all-purpose flour, ¾ cup (150 g) granulated sugar, 1 tablespoon baking powder, ½ teaspoon baking soda, and ¼ teaspoon salt. Whisk well to evenly distribute the leavening agents. (Time: 3 minutes)
3. In a separate bowl, whisk together the wet ingredients: 1 cup (240 ml) milk, 2 large eggs (room temperature), 1 cup (240 ml) sourdough discard, and 6 tablespoons (85 g) melted unsalted butter. Whisk until smooth and combined. (Time: 5 minutes)
4. Pour the wet mixture into the dry ingredients. Stir gently with a spatula until everything is just combined. Don’t overmix—you want the batter to be a bit lumpy, not smooth. Overmixing can make it dense. (Time: 2 minutes)
5. Pour half of the batter into your prepared casserole dish. Spread evenly with a spatula. (Time: 2 minutes)
6. In a small bowl, mix the cinnamon swirl: 3 tablespoons cinnamon and ½ cup (100 g) brown sugar. Sprinkle half of this mixture evenly over the batter layer. (Time: 2 minutes)
7. Top with the remaining batter. Spread carefully to cover the cinnamon sugar layer. Then sprinkle the rest of the cinnamon sugar mixture on top. This layering creates those gooey, cinnamon pockets. (Time: 3 minutes)
8. Bake for 40-45 minutes. The casserole should puff up and turn golden brown. A toothpick inserted in the center will come out mostly clean with a few moist crumbs. If it browns too quickly, tent with foil. (Time: 45 minutes)
9. While baking, prepare the cream cheese glaze: In a medium bowl, beat 4 ounces (115 g) softened cream cheese with 1 cup (120 g) powdered sugar and 1 teaspoon vanilla extract until smooth. Add 1-2 tablespoons milk or cream to reach a drizzling consistency. (Time: 5 minutes)
10. Once the casserole is out of the oven, let it cool 10 minutes. Drizzle the glaze over the warm casserole. The glaze will soften slightly and seep into the cinnamon pockets. (Time: 10 minutes)
11. Serve warm. Dig in and enjoy the layers of sweet, tangy, and creamy goodness!

Pro tip: If you find the edges are browning faster than the center, rotate the dish halfway through baking. Also, I like to prepare the glaze while the bake is in the oven to save time. The cream cheese glaze always feels like a tiny reward after the wait!

Cooking Tips & Techniques

Getting this Easy Sourdough Discard Cinnamon Roll Casserole just right is all about a few small details:

• Use room temperature eggs and milk: This helps the batter mix more evenly and rise better. Cold ingredients can slow the leavening reaction.
• Don’t overmix the batter: Overworking gluten in the flour can turn your casserole tough instead of tender. Stir until just combined—lumps are okay.
• Keep an eye on oven temperature: Many home ovens run hot or cold. An oven thermometer helps avoid burnt edges or undercooked centers.
• Layer cinnamon sugar carefully: Make sure to distribute the cinnamon sugar evenly for those signature gooey pockets. I sometimes swirl it gently with a knife after sprinkling.
• Make the glaze smooth: Beat the cream cheese glaze well to avoid lumps. If it’s too thick, add milk a teaspoon at a time until it drizzles easily but isn’t runny.
• Timing matters: Let the casserole cool slightly before glazing. If you glaze it too hot, the cream cheese will melt and lose that velvety texture.

I learned the hard way that skipping the baking powder or soda leads to a flat, dense bake. Also, at one point I tried subbing sourdough discard with plain yogurt—nice flavor, but the texture was off. So stick with the discard for that perfect tang and rise. And when hosting, I sometimes multitask by prepping the glaze while guests mingle—it’s a little kitchen hack that keeps things smooth.

Variations & Adaptations

This casserole is pretty versatile, so feel free to tweak it to suit your taste or dietary needs:

• Vegan Version: Use a plant-based milk like almond or oat, replace eggs with flax eggs (2 tablespoons ground flaxseed + 6 tablespoons water), and swap cream cheese for a vegan cream cheese alternative.
• Pumpkin Spice Twist: Add ½ cup pumpkin puree to the batter and swap cinnamon for pumpkin pie spice. This variation is perfect for autumn mornings.
• Nutty Crunch: Sprinkle chopped pecans or walnuts over the top cinnamon sugar layer before baking for added texture and flavor.
• Fruit Boost: Fold in ½ cup fresh or frozen blueberries or diced apples into the batter before pouring into the dish.
• Gluten-Free: Use a gluten-free all-purpose flour blend in place of regular flour. The texture may be slightly denser but still delicious.

Personally, I once tried a maple glaze instead of cream cheese, mixing powdered sugar with pure maple syrup and a splash of milk. It was a nice change for a brunch crowd. For a savory twist, though less traditional, I’ve seen readers combine sourdough discard with herbs and cheese for breakfast bakes—just not quite the cinnamon roll vibe!

Serving & Storage Suggestions

This casserole is best served warm, fresh from the oven or gently reheated. The cream cheese glaze softens beautifully when warmed, making each bite luscious and comforting. I like to plate it with a dusting of cinnamon or a few fresh berries for color and brightness.

It pairs wonderfully with freshly brewed coffee or a sparkling mimosa for a special weekend brunch. For a lighter contrast, a simple fruit salad or the classic tuna melt on sourdough bread complements the sweetness nicely if you’re serving a larger spread.

To store, cover leftovers tightly with plastic wrap or foil and refrigerate for up to 3 days. Reheat gently in the microwave or oven to bring back that soft, gooey texture. This casserole also freezes well—wrap portions individually in plastic wrap and foil, then thaw overnight in the fridge before reheating.

Flavors tend to meld over time, so sometimes I find that the casserole tastes even better the day after baking. The cinnamon pockets become more pronounced, and the glaze slightly soaks in, creating a cozy, homestyle treat.
