- Pure maple syrup: The star of the show, lending unmistakable maple flavor and moisture.
- Large eggs (room temperature): Bind everything together and help the cake rise beautifully.

- Vanilla extract: Rounds out the flavor with a sweet, aromatic note.
- Chopped walnuts (toasted): Bring crunch and a nutty richness that perfectly complements the maple.

How to Make Decadent Maple Syrup and Walnut Cake
Step 1: Prepare the Pan and Preheat the Oven
Start by heating your oven to 350°F (175°C). Grease and flour a 9-inch round or square cake pan, or line it with parchment paper for easy removal. This step ensures your Decadent Maple Syrup and Walnut Cake releases effortlessly and bakes evenly.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon. Blending these dry ingredients first guarantees that the leaveners and spices are evenly distributed, setting the stage for a perfectly tender cake.
Step 3: Cream the Butter and Sugar
In a large mixing bowl, beat the softened butter and brown sugar together until light and fluffy—this usually takes about 2–3 minutes. This crucial step incorporates air, giving your cake a lovely, light texture.
Step 4: Add Maple Syrup and Eggs
Pour in the pure maple syrup and mix until fully combined, then add the eggs one at a time, beating well after each addition. This process ensures all the wet ingredients are smoothly blended, infusing the batter with rich maple flavor.
Step 5: Incorporate Sour Cream and Vanilla
Stir in the sour cream and vanilla extract, which add moisture and a subtle tang that balances the sweetness beautifully in your Decadent Maple Syrup and Walnut Cake.
Step 6: Combine Wet and Dry Ingredients
Gradually add the dry mixture to the wet ingredients, mixing gently until just combined. Be careful not to overmix, as this could make the cake dense instead of soft and fluffy.
Step 7: Fold in Toasted Walnuts
Gently fold in the toasted, chopped walnuts. Their nutty crunch is the perfect contrast to the cake’s tender crumb, adding both flavor and texture in every bite.
Step 8: Bake the Cake
Pour the batter into your prepared pan and smooth the top with a spatula. Bake for 35–40 minutes, or until a toothpick inserted into the center comes out clean. The aroma filling your kitchen will be absolutely irresistible!
Step 9: Cool and Glaze
Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely. While it cools, whisk together the powdered sugar and maple syrup for the glaze, adding milk as needed until it’s silky and pourable. Drizzle the maple glaze generously over the cooled cake before serving.
How to Serve Decadent Maple Syrup and Walnut Cake

Garnishes
A beautiful finish makes all the difference! For an elegant touch, sprinkle a handful of whole or chopped toasted walnuts over the glaze. If you want to take it up a notch, a light dusting of powdered sugar or a dollop of softly whipped cream makes your Decadent Maple Syrup and Walnut Cake even more irresistible.
Side Dishes
This cake pairs wonderfully with a steaming mug of coffee or a soothing cup of tea. For a festive brunch, serve it alongside fresh fruit or a scoop of vanilla ice cream to balance the warm, nutty sweetness.
Creative Ways to Present
For special occasions, try cutting the cake into small squares and arranging them on a tiered platter for an impressive dessert display. You can also layer slices with whipped cream and berries in parfait glasses for a stunning, deconstructed take on Decadent Maple Syrup and Walnut Cake.
Make Ahead and Storage
Storing Leftovers
Store any leftover cake covered at room temperature for up to 3 days. An airtight container will help keep it moist and flavorful, while the glaze stays delightfully silky on top.
Freezing
To freeze, wrap individual slices or the whole cake (without glaze) tightly in plastic wrap and then foil. Freeze for up to 2 months. When you’re ready to enjoy, thaw at room temperature and add the fresh glaze just before serving.
Reheating
If you’d like to serve your cake warm, heat individual slices in the microwave for 10–15 seconds. The warmth brings out the maple aroma and makes the walnut pieces extra fragrant—just be sure to add a little extra glaze after reheating if needed.
FAQs
Can I use maple-flavored syrup instead of pure maple syrup?
While you can substitute maple-flavored syrup in a pinch, pure maple syrup truly shines in this recipe and delivers a richer, more authentic flavor in your Decadent Maple Syrup and Walnut Cake.
What’s the best way to toast walnuts?
Spread the chopped walnuts on a baking sheet and toast in a 350°F (175°C) oven for about 5–7 minutes, stirring once halfway through. This brings out their nutty aroma and makes them extra crunchy for the cake.
Can I make this cake in advance?
Absolutely! You can bake the cake a day ahead and store it, unglazed, at room temperature. Add the maple glaze just before serving for the freshest flavor and presentation.
Is there a substitute for sour cream?
Yes, plain Greek yogurt works well as a substitute for sour cream in this recipe, giving you the same moist, tender crumb in your Decadent Maple Syrup and Walnut Cake.
Can I use a different type Dessert
If walnuts aren’t your favorite, feel free to use pecans or even hazelnuts for a delicious twist. Just be sure to toast them first for the best flavor and crunch.
