Lemon season is in full swing here, and while I was lamenting a lack of lemons from my heavily pruned tree, a dear friend gave me a huge bag full.

So yippee, I get to bake all things lemon, and there’s not much I like more than these delicious Lemon Bars (or Sticky Lemon Slice as we call it here).

This recipe was given to me by my friend Monique over 30 years ago. I was living in Japan at the time, and wrote out friends’ favourites in a notebook, ready to cook when I returned home and had an oven to cook in.

It’s an easy recipe to love, as it’s super easy, uses just 6 ingredients, and, of course, is delicious.

So let’s get started.

There’s two parts to this recipe, a base which you par bake, and then the delicious topping.

If you’re impatient to just see the recipe and get cooking, here it is. If you’d like some tips as you go, scroll on down past the recipe.

Tips for making the delish Lemon Bars

I make the base in my KitchenAid mixer, and the topping I make in my Thermomix (but you can use a blender / food processor).

Start with your base as below, making sure your butter is soft (but not melted) to begin. Cream it for a good 3 minutes, before adding the flour.  Spread out in your sponge roll tin, that’s lined with baking paper.

When that goes into the oven, you can start on your topping. If you’re using a food processor (or thermomix) you can save yourself a little time. First peel your lemons with a potato peeler, then pop the peel in your bowl with the sugar, and chop/process until your lemon rind is fine. This will smell so good!

Your slice as it heads back into the oven for it’s second cooking.

This is what your bars should look like as they come out of the oven. You’re looking for a nice browning on top, and for no ‘jiggle’ in the middle as you take it out.

A recipe with meaning

This is the recipe in my notebook, written out over 30 years ago by me. And yes, I still use this little book, and love having recipes written out / on paper to cook from. I find it fascinating to see what I was interested in cooking then. It’s incredible how much my tastes and food have changed over these years, and what has stood the test of time.

Sticky Lemon Slice recipe - handwritten in my notebook 30 years ago

You’ll see in the book it’s called Sticky Lemon Slice. It’s funny how different countries name things. My North American friends tend to call this type of food a ‘bar’ whilst downunder we’d call it a ‘slice’.

This would be a typical item we’d serve for morning or afternoon tea. Actually, whether or not I’m ‘serving’ it, this slice is a typical food I’d eat for morning or afternoon tea. 🤤

The recipe is a family favourite, and every time I make it, I think of Monique who baked it for me the first time.

I hope this becomes a family favourite for you too.

Make sure you pop back here after you’ve made it, to let me know your thoughts.

Pin this so you know just where to find it when you make it again!

    These look delicious. My lemon tree fruit is almost ripe. I know what I’m going to do with some of it.
