Ingredients You’ll Need

Every ingredient in this Banana Walnut Cake with Sweet Syrup plays an essential role in creating its signature taste and texture. From the fragrant cinnamon to the creamy softness of yogurt, each element works together to bake a cake that’s rich but not heavy, sweet yet balanced, and loaded with delightful nutty crunch.

• 2 cups all-purpose flour: The backbone of the cake, providing structure and tenderness.
• 1 teaspoon baking soda: Helps the cake rise and become airy by reacting with the banana’s acidity.
• ½ teaspoon baking powder: Gives a gentle lift to keep the cake light.
• ½ teaspoon salt: Balances the sweetness and enhances the flavors.
• 1 teaspoon ground cinnamon: Adds a warm, comforting spice that highlights the bananas.
• ½ cup unsalted butter, softened: Brings moisture and richness without overpowering other flavors.
• ¾ cup brown sugar: Deep caramel notes that meld beautifully with bananas and walnuts.
• 2 large eggs: Bind everything together, adding to the cake’s soft, dense crumb.
• 3 ripe bananas, mashed: The star of the show, providing natural sweetness and incredible moistness.
• ½ cup plain yogurt or sour cream: Adds tanginess and keeps the crumb tender and velvety.
• 1 teaspoon vanilla extract: Enhances all the cake’s flavors with its sweet aroma.
• ¾ cup chopped walnuts: Bring crunch and earthiness, creating contrast in every bite.
• ½ cup granulated sugar (for syrup): Sweetens the syrup that soaks into the cake for extra moistness.
• ½ cup water (for syrup): Dissolves the sugar to create a silky syrup.
• 1 teaspoon vanilla extract (for syrup): Infuses the syrup with fragrant warmth that complements the cake.

How to Make Banana Walnut Cake with Sweet Syrup

Step 1: Prepare Your Pan and Oven

Start by preheating your oven to 350°F (175°C). Grease your favorite loaf pan or a 9-inch round cake pan, then line it with parchment paper for an easy release. This prep ensures your cake bakes evenly and lifts out effortlessly after baking.

Step 2: Mix the Dry Ingredients

In a medium bowl, whisk together the all-purpose flour, baking soda, baking powder, salt, and cinnamon. Combining these dry ingredients first not only ensures even distribution but also prevents any lumps that could affect your cake’s texture.

Step 3: Cream Butter and Sugar

In a large bowl, cream together the softened butter and brown sugar until the mixture is light and fluffy. This step is essential as it incorporates air into the batter, helping your cake achieve a tender crumb and beautiful rise.

Step 4: Add Eggs and Flavorings

Beat in the eggs one at a time, making sure each egg is fully incorporated before adding the next. Then stir in the mashed bananas, plain yogurt (or sour cream), and vanilla extract. These ingredients create a moist, flavorful batter with a touch of tang from the yogurt that balances the sweetness magnificently.

Step 5: Combine Wet and Dry Ingredients

Gently fold in the dry ingredients just until combined; overmixing can make your cake tough. Then, add the chopped walnuts and give one last gentle stir to distribute them evenly without breaking them down too much.

Step 6: Bake the Cake

Pour the batter into your prepared pan and smooth the top with a spatula for even baking. Pop it into the oven and bake for 40 to 45 minutes, or until a toothpick inserted in the center comes out clean. The aroma filling your kitchen at this point is pure bliss!

Step 7: Make the Sweet Syrup

While the cake is baking, combine the granulated sugar and water in a small saucepan. Bring it to a simmer and cook for 3 to 4 minutes until the sugar dissolves completely. Remove from heat and stir in the vanilla extract. This syrup is what will give your cake that irresistible moist finish.

Step 8: Apply the Syrup and Cool

As soon as the cake comes out of the oven, pour the warm sweet syrup evenly over the top. Let the cake absorb the syrup before transferring it to a wire rack to cool completely. This step locks in moisture and adds a glossy, sweet finish that makes each bite explode with flavor.

How to Serve Banana Walnut Cake with Sweet Syrup

Garnishes

For a simple and elegant touch, sprinkle a few extra chopped walnuts or a light dusting of powdered sugar over the cooled cake. If you want to get a little fancier, add a dollop of whipped cream or a scoop of vanilla ice cream to enhance the cake’s richness and create a show-stopping dessert.

Side Dishes

This Banana Walnut Cake with Sweet Syrup pairs beautifully with a hot cup of coffee or a fragrant cup of chai tea. For brunch or afternoon tea, serve alongside fresh berries or a citrus salad to cut through the cake’s sweetness and brighten every bite.

Creative Ways to Present

Slice the cake thickly and layer it with cream cheese frosting and additional walnuts for a banquet-worthy treat. Or, for a fun twist, use cut-out shapes from the loaf as a base for mini layered desserts with yogurt and fruit. The moist texture and walnut crunch make it incredibly versatile.

Make Ahead and Storage

Storing Leftovers

Wrap leftover banana walnut cake tightly in plastic wrap or store it in an airtight container at room temperature for up to 3 days. Keeping it covered prevents it from drying out, allowing the lovely moist texture to stay intact.

Freezing

This cake freezes beautifully. Wrap individual slices or the whole cake in plastic wrap and then in aluminum foil before placing in the freezer. It can be frozen for up to 3 months. When you’re ready for a slice, thaw it overnight in the fridge or at room temperature.

Reheating

Warm slices gently in the microwave for 15 to 20 seconds or pop them in a preheated oven at 300°F (150°C) for about 10 minutes. Reheating reinvigorates the sweet syrup so it melts into the cake, offering a near-fresh-baked experience.

FAQs

Can I use walnuts that are not toasted?

Yes! While toasting walnuts enhances their flavor and crunch, using untoasted walnuts works perfectly fine. You can toast them in a dry pan over medium heat for a few minutes if you want to deepen their flavor before adding them to the batter.

Is plain yogurt essential, or can I substitute it?

Plain yogurt or sour cream helps keep the cake moist and lends a slight tang that balances sweetness. If you don’t have them, you could substitute with buttermilk or even milk mixed with a little lemon juice, but the texture might be slightly different.

How ripe should my bananas be?

The riper, the better. Bananas with lots of brown spots or that are very soft work best for this cake because they are sweeter and mash easily, infusing the batter with maximum flavor and moisture.

Can I make this cake gluten-free?

Absolutely. Swap the all-purpose flour for a quality gluten-free flour blend that includes xanthan gum. Keep an eye on the batter’s consistency; gluten-free batters can be a bit different, so a slight adjustment in liquid might be needed.

What is the purpose of the sweet syrup?

The sweet syrup is the secret behind this cake’s unforgettable moistness and extra layer of flavor. Poured warm over the hot cake, it soaks in to enhance sweetness and create a lovely glossy surface, making each slice irresistibly soft and luscious.
