Ways with Walnuts
There are many ways to eat nuts. I particularly like walnuts the most. Toast them in an oven with some brown sugar, sprinkle them on a salad, wrap them with blue cheese in ravioli, etc. Today I am going to share with you how I add walnut into my cake recipe.
My husband has the tendency to eat the same lunch every day – and it isn’t a particularly healthy or nutritious lunch, so recently I made the decision that I’d make him a salad every day. I know he likes salad because he hates the sleepy feeling you can get from a big lunch and now I also know that he is eating something healthy!
Actually, we eat salad as our main dinner once or twice every week – either with rice or pasta, or sometimes with pan-fried chicken breast and my irresistible signature garlic bread. I’ll share some of my salad recipes in a future post.
Salad is just the name of a type of dish. It can be made with virtually anything – different varieties of ingredients and with different delicious dressings and drizzles. We like freshly squeezed lime juice or good quality oils such as extra virgin olive oil or flax seed oil. You can add pretty much whatever you like to a salad. Obviously, the more veggie, the healthier it will be. For my husband, he likes carrots, bell peppers and couscous so these are often the main ingredients in his salad. I avoid giving him the same salad every day with little tricks that make it a bit different (he probably doesn’t notice!). I also add green leaves, such as kale, rocket, spinach or lettuce, a little bit of protein, usually canned salmon or mackerel and his favourite ingredient – toasted nuts. It can be toasted walnuts, pine nuts or almonds – but often walnuts.
The Goodness of Walnuts
Walnuts are really good for our bodies. When I was young, my mum told me eating walnuts is good for the brain because the shape of a whole walnut looks like the human brain. In a Chinese sense, eating something that is similar to the body part is good for that body part. I still like to believe this is true (and you should always listen to your Mother!).

Tips for Making the BEST Banana Walnut Cake
- Choose super ripe bananas – The darker the peel, the sweeter and more flavorful the cake will be. Overripe bananas mash easily and blend into the batter better.
- Toast the walnuts – Lightly toasting walnuts in the oven or a dry pan before adding them to the batter brings out their nutty aroma and flavor. Let them cool before mixing in.
- Measure ingredients accurately – Use a kitchen scale for the flour, sugar, and butter to ensure consistent results. Too much flour can make the cake dry.
- Don’t overmix – Once you add the dry ingredients to the wet mixture, stir only until just combined. Overmixing can make the cake dense instead of soft and tender.
- Use room-temperature eggs and milk – This helps the batter blend more evenly and creates a better texture.
- Check for doneness early – Ovens vary, so start testing with a skewer around 30–35 minutes to avoid over baking.
- Cover if browning too quickly – If the walnuts or top get too dark before the inside is baked, loosely cover with foil and continue baking.
- Let it cool before slicing – This keeps the crumb intact and prevents the cake from falling apart.
How to Serve this Banana Walnut Cake
- Classic & Simple – Slice and enjoy it as is with a cup of tea or coffee.
- Warm & Cozy – Serve slightly warm with a pat of butter melting on top.
- With a Sweet Drizzle – Add a light dusting of powdered sugar or drizzle with honey, maple syrup, or caramel sauce.
- A Little Extra Creaminess – Pair with a scoop of vanilla ice cream, whipped cream, or Greek yogurt.
- For Breakfast or Brunch – Toast a slice lightly and spread with cream cheese, nut butter, or fruit jam.
How to Store this Banana Walnut Cake
- Room Temperature – Keep in an airtight container for up to 2–3 days. Store in a cool, dry spot away from direct sunlight.
- Refrigerator – For longer freshness, wrap the cake tightly in plastic wrap or place in an airtight container. Refrigerate for up to 5 days. Bring to room temperature before serving for the best flavor and texture.
- Freezer – Wrap the whole loaf or individual slices in plastic wrap, then place in a freezer-safe bag or container. Freeze for up to 2 months. Thaw at room temperature or warm slightly in the microwave before enjoying.
Let’s be real — this banana walnut cake rarely sticks around long enough to even consider freezing it. It’s usually gone within a couple of days (sometimes faster, if I’m being honest!). So while it’s good to know how to store it, chances are you’ll be enjoying every last crumb fresh and warm. But if you do have leftovers, just keep it airtight at room temp or pop it in the fridge to keep it tasting its best.
Frequently Asked Questions
Overripe bananas are best because they’re sweeter and mash easier, giving the cake more flavor and moisture. But if you only have ripe bananas, it’ll still work — just maybe add a little extra sugar to balance it out.
Absolutely! Pecans, almonds, or hazelnuts all make great swaps. Just toast them lightly for extra crunch and flavour.
Insert a skewer or knife into the centre — if it comes out clean or with just a few moist crumbs, it’s ready. If there’s wet batter, it needs more time.
Definitely! Chocolate chips or raisins add a nice twist. Just fold them in with the walnuts before baking.

- 160 g cake flour
- 1/2 tsp baking soda
- 1 tsp baking powder

Instructions
- Preheat the oven to 170°C/ 350°F (remember, each oven is different, find your own best heat). Line and grease a 1lb loaf tin.
- Melt the butter in a saucepan. Then pour the butter into a mixing bowl with the sugar and stir in.

I have a question before I make this banana walnut cake. Is the butter salted or unsalted?
Hi Lyn!
Thanks for your question. It is unsalted butter. If you like, you can add 1/4 tsp of salt to even enhance the flavour. Hope it helps! Let me know how it turns out! Happy baking!
