- Unsalted butter (softened): Adds richness and keeps the cake moist.
- Brown sugar: Contributes deep, caramel notes that blend wonderfully with maple syrup.
- Pure maple syrup: The star sweetener that infuses the cake with its signature flavor.
- Large eggs: Bind the ingredients and provide structure.
- Vanilla extract: Elevates the cake’s aroma and rounds out the sweetness.
- Sour cream: Adds moisture and a slight tang that balances the sweetness.
- Chopped walnuts (toasted): Offer crunch and a toasty, nutty richness.

How to Make Decadent Maple Syrup and Walnut Cake Recipe
Step 1: Prepare Your Ingredients and Oven
Start by preheating your oven to 350°F and preparing an 8-inch cake pan by greasing it and dusting with flour or lining it with parchment paper. This simple step ensures your cake will release easily after baking without sticking or breaking apart.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. This ensures even distribution of the leavening agents and seasoning, which is key for an even rise and balanced flavor throughout your cake.
Step 3: Cream Butter and Sugar
In a large bowl, beat the softened butter and brown sugar until light and fluffy, about 2 to 3 minutes. This step is crucial because it incorporates air into the batter, giving your cake that soft, tender texture we all love.
Step 4: Add Eggs, Maple Syrup, and Vanilla
Add the eggs one at a time, beating well after each to ensure a smooth batter. Follow with the maple syrup and vanilla extract, mixing until fully combined. These ingredients create the rich body and signature flavor that define this cake.
Step 5: Incorporate Sour Cream
Blend in the sour cream, which brings moisture and a slight tang that perfectly complements the sweetness of maple syrup, preventing the cake from tasting overly sweet or dense.
Step 6: Combine Dry and Wet Ingredients
Gradually add the dry flour mixture to the wet batter in batches, mixing gently until just combined. Overmixing at this stage can lead to a tough cake, so fold carefully.
Step 7: Fold in Toasted Walnuts
Gently fold in the toasted chopped walnuts to distribute their crunch throughout the batter. Toasting the walnuts beforehand enhances their flavor, giving your cake that extra depth and texture.
Step 8: Bake the Cake
Pour the batter into your prepared pan, smoothing the top with a spatula. Bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out clean. Once baked, let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. Cooling is important because it allows the cake to set, making it easier to glaze.
Step 9: Prepare the Maple Glaze
In a small saucepan over medium heat, melt together the maple syrup and butter. Once melted, remove from heat and whisk in powdered sugar, vanilla extract, and a pinch of salt until you achieve a smooth, glossy glaze. The balance of sweet and salty in the glaze ties the whole cake experience together.
Step 10: Glaze and Garnish the Cake
Drizzle the glaze evenly over the cooled cake and sprinkle with the lightly toasted walnuts for a beautiful finishing touch. Allow the glaze to set before slicing to get clean, elegant slices.
How to Serve Decadent Maple Syrup and Walnut Cake Recipe

Garnishes
For an irresistible presentation, add a few extra toasted walnut halves on top of the glaze right before serving. You can also sprinkle a light dusting of powdered sugar for that delicate snowy effect which looks stunning and adds a hint of extra sweetness.
Side Dishes
This cake pairs wonderfully with a scoop of vanilla bean ice cream or a dollop of freshly whipped cream to balance the rich maple flavor. A hot cup of coffee or chai tea alongside enhances the cozy, comforting experience.
Creative Ways to Present
For a festive touch, serve slices of this Decadent Maple Syrup and Walnut Cake Recipe on rustic wooden boards with clusters of fresh fruit like figs or sliced pears. You can also layer the cake with whipped cream and a drizzle of extra maple syrup for a quick trifle dessert that impresses at any dinner party.
Make Ahead and Storage
Storing Leftovers
Store any leftover cake in an airtight container at room temperature for up to 3 days to keep it moist and flavorful. If your kitchen is warm, refrigeration is fine but bring the cake to room temperature before serving for the best texture.
Freezing
You can freeze the cake (unfrosted) by wrapping it tightly in plastic wrap and then aluminum foil. It will keep well in the freezer for up to 2 months. Thaw overnight in the refrigerator and glaze fresh before serving to enjoy the full flavor and texture.
Reheating
If you prefer warm cake, reheat slices gently in a microwave for 15 to 20 seconds or in a low oven (around 300°F) for 5-10 minutes. This restores a fresh-baked feel that’s so comforting when paired with a spread of butter or maple cream cheese.
FAQs
Can I substitute walnuts for another nut?
Absolutely! Pecans or almonds work beautifully as they also toast well and provide that delightful crunch. Just be sure to toast them first to bring out the best flavor.
Is this cake gluten-free friendly?
This recipe calls for all-purpose flour, so it’s not gluten-free as is. However, you can try substituting a gluten-free baking blend, but be mindful that texture might vary slightly.
Can I make this cake dairy-free?
Yes! Use dairy-free butter alternatives and a suitable sour cream substitute, such as coconut yogurt or almond-based sour cream, to keep it moist and rich while avoiding dairy.
What’s the best way to toast walnuts?
Simply spread the walnuts in a single layer on a baking sheet and toast them in a preheated 350°F oven for 8–10 minutes, stirring halfway through. Keep an eye on them to prevent burning.
Can I double this recipe for a larger cake?
Definitely! Doubling the recipe and baking in two pans is perfect for a layered cake. Just bake each layer separately and adjust baking times if using larger pans.

Perfectly complemented by a smooth maple glaze and topped with extra toasted walnuts, this cake is ideal for fall gatherings or anytime you crave a comforting, homemade treat.
Ingredients
For the Cake:
- 1¾ cups all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- ½ cup unsalted butter (softened)
- ½ cup brown sugar
- ½ cup pure maple syrup
- 2 large eggs
- 1 teaspoon vanilla extract
- ½ cup sour cream
- ½ cup chopped walnuts (toasted)
For the Maple Glaze:
- ¼ cup pure maple syrup
- 2 tablespoons butter
- ½ cup powdered sugar
- ¼ teaspoon vanilla extract
- pinch of salt
For Topping:
- ¼ cup chopped walnuts (lightly toasted)
Instructions
- Prepare the Cake Batter: Preheat your oven to 350°F (175°C). Grease and flour an 8-inch round or square cake pan, or line it with parchment paper to prevent sticking. In a medium bowl, whisk together the flour, baking powder, baking soda, and salt to ensure even distribution of leavening agents.
- Cream Butter and Sugar: In a large bowl, use an electric mixer to cream the softened butter and brown sugar together until the mixture is light and fluffy, approximately 2 to 3 minutes. This process incorporates air, helping the cake rise.
- Add Wet Ingredients: Beat in the eggs one at a time, making sure each egg is fully incorporated before adding the next. Stir in the pure maple syrup and vanilla extract until well combined. Then mix in the sour cream until the batter is smooth and homogeneous.
- Combine Dry and Wet Ingredients: Gradually add the dry flour mixture to the wet ingredients, mixing gently until just combined to avoid overworking the batter, which can make the cake tough. Fold in the toasted chopped walnuts evenly throughout the batter.
- Bake the Cake: Pour the prepared batter into your greased pan, smoothing the top with a spatula for even baking. Place in the oven and bake for 30 to 35 minutes, or until a toothpick inserted into the center of the cake comes out clean. This ensures the cake is fully baked through.
- Cool the Cake: Once baked, allow the cake to cool in the pan for 10 minutes to set. Then carefully transfer it to a wire rack to cool completely, which will help the glaze adhere properly and prevent melting.
- Prepare the Maple Glaze: In a small saucepan over medium heat, combine the maple syrup and butter. Stir occasionally until the butter fully melts, then remove from heat. Whisk in powdered sugar, vanilla extract, and a pinch of salt until the glaze is smooth and glossy.
- Glaze and Garnish: Drizzle the maple glaze evenly over the cooled cake. Immediately sprinkle the top with the lightly toasted chopped walnuts to add crunch and enhance flavor. Let the glaze set at room temperature before slicing and serving to ensure clean cuts.
Notes
- For a layer cake, double the recipe and divide it evenly between two 8-inch cake pans for baking.
- Add a pinch of cinnamon to the batter to introduce a warm spice note, perfect for fall flavor.
- Ensure walnuts are toasted to bring out their full flavor and crunch before adding them to the batter and topping.
- Use pure maple syrup for the best natural sweetness and flavor depth.
