Cinnamon Swirl Donut Loaf Ingredients
For the Loaf
- All-purpose flour – Provides structure and texture for the loaf; substitute whole wheat for added nutrition.
- Baking powder – Acts as a leavening agent; ensure freshness for the best rise.
- Baking soda – Works with baking powder for lightness; replace if expired for optimal results.
- Salt – Enhances flavor; kosher salt can be used as an alternative.
- Ground cinnamon – Main flavor agent, providing warmth and sweetness; use quality, fresh cinnamon for the best taste.
- Granulated sugar – Adds sweetness and moisture; can substitute with coconut sugar for a lower glycemic index.
- Brown sugar – Contributes moisture and caramel notes; choose light or dark for your preferred richness.
- Unsalted butter – Adds richness; can substitute with margarine or a non-dairy alternative.
- Eggs – Provide binding and moisture; for a vegan option, use flaxseed meal mixed with water.
- Buttermilk – Keeps the loaf tender; mix milk with lemon juice or vinegar for a DIY substitute.
- Vanilla extract – Enhances overall flavor; opt for pure vanilla extract for the best results.
For the Cinnamon Sugar Topping
- Granulated sugar – Sweetens the topping and adds texture; blending with brown sugar gives a deeper flavor.
- Ground cinnamon – Complements the topping, creating a sweet crust; stick to ground for enhanced flavor.
- Unsalted butter – Helps the mixture adhere well to the loaf; melted coconut oil is a great dairy-free option.
Step‑by‑Step Instructions for Cinnamon Swirl Donut Loaf
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms, grease a 9×5-inch loaf pan with butter or non-stick spray, ensuring all sides are well-coated. This will prevent the delicious Cinnamon Swirl Donut Loaf from sticking to the pan later.
Step 2: Mix Dry Ingredients
In a medium bowl, combine 2 cups of all-purpose flour, 2 teaspoons of baking powder, 1 teaspoon of baking soda, 1 teaspoon of salt, and 2 teaspoons of ground cinnamon. Whisk the mixture thoroughly until all dry ingredients are evenly distributed and there are no clumps. This step is essential for a uniformly textured loaf.
Step 3: Cream Butter and Sugars
In a large mixing bowl, beat ½ cup of softened unsalted butter, ¾ cup of granulated sugar, and ¾ cup of brown sugar together using an electric mixer. Mix on medium speed until the mixture turns light and fluffy, approximately 3-4 minutes. The creamy texture will enhance the moisture and richness of your Cinnamon Swirl Donut Loaf.
Step 4: Add Eggs
Now, add 2 large eggs to your butter-sugar mixture, one at a time. Beat well after each addition until fully incorporated. This should take about 1-2 minutes. The eggs will help bind the ingredients and add to the overall richness of the loaf.
Step 5: Incorporate Wet Ingredients
Pour in ½ cup of buttermilk and 1 teaspoon of vanilla extract into the mixture. Stir until everything is well combined. This step introduces a lovely tang and complexity to the flavor profile of your Cinnamon Swirl Donut Loaf.
Step 6: Blend Ingredients
Carefully add your dry mixture to the wet batter in two batches, alternating with remaining ½ cup of buttermilk, mixing on low speed. Blend until just combined, avoiding overmixing to ensure a light and tender loaf.
Step 7: Prepare Cinnamon Swirl
In a separate small bowl, mix together ¼ cup of granulated sugar and 2 teaspoons of ground cinnamon. In your greased loaf pan, layer half of the batter, sprinkle half of the cinnamon sugar mixture over it, and gently swirl with a knife. Repeat this process with the remaining batter and cinnamon topping, creating swirls of sweet cinnamon goodness.
Step 8: Bake the Loaf
Place the prepared loaf pan in the preheated oven and bake for 50-60 minutes. To check if it’s done, insert a toothpick into the center— it should come out clean or with a few moist crumbs. The top should turn a lovely golden brown.
Step 9: Cool the Loaf
Once baked, remove the loaf pan from the oven and allow it to cool in the pan for about 10 minutes. This helps it set properly. Afterward, gently transfer the Cinnamon Swirl Donut Loaf to a wire rack to cool completely.
Step 10: Optional Glaze
For an extra special treat, while the loaf cools, mix 1 cup of powdered sugar with 2 tablespoons of milk until smooth. Once your loaf has cooled, drizzle the glaze over the top for an added layer of sweetness, enhancing the flavors of your delightful Cinnamon Swirl Donut Loaf!

Cinnamon Swirl Donut Loaf Recipe FAQs
How do I choose the right ground cinnamon for this recipe?
Absolutely! Using a quality, fresh ground cinnamon can make a big difference in flavor. Look for a brand that lists ground cinnamon as the only ingredient. Avoid blends or stale spices, as they lack that warm, sweet aroma that you want in your Heavenly Cinnamon Swirl Donut Loaf.
What’s the best way to store leftovers?
You can store leftovers in an airtight container at room temperature for up to 3 days to keep the loaf moist. If you want to enjoy it longer, refrigerate it for up to a week. Just be aware that refrigeration can dry it out a bit, so enjoy it soon!
Can I freeze this Cinnamon Swirl Donut Loaf?
Very! This delightful loaf freezes beautifully. To freeze, slice it first, then wrap each slice tightly in plastic wrap. After wrapping, place the slices in a freezer bag for extra protection. Your Cinnamon Swirl Donut Loaf will stay delicious for up to 3 months. When you’re ready to indulge, simply thaw at room temperature or heat it in the microwave for 15-20 seconds for a cozy experience!
Why is my loaf dense or heavy?
If your loaf came out dense, it might be due to overmixing the batter or using expired leavening agents like baking powder or baking soda. Make sure to gently mix the wet and dry ingredients until just combined, and always check the freshness of your baking powder and soda before starting to ensure that delightful rise.
Is this recipe suitable for those with egg allergies?
Good question! You can make this recipe egg-free by replacing each egg with 1 tablespoon of flaxseed meal mixed with 2.5 tablespoons of water. Allow it to sit for a few minutes until it thickens. This flax egg works well and still adds the necessary binding to your Heavenly Cinnamon Swirl Donut Loaf!
Can I use whole wheat flour instead of all-purpose flour?
Certainly! Substituting whole wheat flour for all-purpose flour is a great way to make the loaf a bit healthier. Just keep in mind that whole wheat flour may absorb more moisture, so consider adding an extra tablespoon or two of buttermilk to maintain the loaf’s moisture and tenderness.
