Easy Lemon Traybake Cake - Bright, Zesty, and Perfect for Sharing
Ingredients
- For the cake:
- 225 g (1 cup) unsalted butter, softened
- 225 g (1 cup) caster sugar (or granulated sugar)
- 4 large eggs, room temperature
- 1 tsp vanilla extract
- Zest of 2 large lemons (about 2 tbsp)
- 3 tbsp fresh lemon juice
- 275 g (2 1/4 cups) plain/all-purpose flour
- 2 tsp baking powder
- 1/2 tsp fine salt
- 120 ml (1/2 cup) milk, room temperature
- For the lemon glaze:
- 200 g (about 1 3/4 cups) icing/confectioners’ sugar, sifted
- 3–4 tbsp fresh lemon juice (to desired consistency)
- Optional: extra lemon zest or thin lemon slices to decorate
Instructions
- Prep the pan and oven. Heat the oven to 180°C/160°C fan (350°F).Line a 9x13-inch (23x33 cm) traybake tin with baking paper, leaving an overhang for easy lifting.
- Cream butter and sugar. In a large bowl, beat the softened butter and sugar with an electric mixer for 2–3 minutes until pale and fluffy. This step helps create a light crumb.
- Add eggs and flavorings. Beat in the eggs one at a time, mixing well after each. Stir in vanilla, lemon zest, and lemon juice.The mixture may look slightly curdled—this is normal and will smooth out once dry ingredients are added.
- Combine dry ingredients. In a separate bowl, whisk together flour, baking powder, and salt.
- Alternate dry ingredients and milk. Add half the dry ingredients to the butter mixture, then half the milk. Repeat with the remaining dry ingredients and milk. Mix on low just until combined. Do not overmix.
- Fill the tin. Scrape the batter into the lined tin and spread it evenly to the edges.Tap the tin lightly on the counter to release air bubbles.
- Bake. Bake for 22–28 minutes, or until the top is lightly golden and a skewer inserted in the center comes out clean. The edges should spring back when touched.
- Make the glaze. While the cake bakes, whisk the icing sugar with 3 tbsp lemon juice. Add more juice a little at a time until it’s thick but pourable—like heavy cream.
- Glaze while warm. Let the cake cool in the pan for 10 minutes.Poke small holes across the surface with a skewer, then pour over the glaze and spread to the corners. It will seep in and set with a slight sheen.
- Cool and slice. Allow to cool completely in the tin before lifting out and cutting into squares. Decorate with extra zest or thin lemon slices if you like.
What Makes This Special
This cake delivers big flavor with minimal effort. You don’t need special equipment, and the ingredients are pantry staples plus a few fresh lemons.
The batter comes together in minutes, and it bakes evenly in a tray, so no guessing about doneness in the middle. The glaze is a quick mix of lemon juice and icing sugar that soaks into the warm cake for extra moisture. It’s perfect for birthdays, bake sales, or a sunny afternoon treat.
Ingredients

- 225 g (1 cup) unsalted butter, softened
- 225 g (1 cup) caster sugar (or granulated sugar)

- 1 tsp vanilla extract
- Zest of 2 large lemons (about 2 tbsp)
- 3 tbsp fresh lemon juice
- 275 g (2 1/4 cups) plain/all-purpose flour
- 2 tsp baking powder

How to Store
- Room temperature: Keep covered in an airtight container for up to 3 days.The glaze helps keep it moist.
- Fridge: Not required, but if your kitchen is warm, refrigerate for up to 5 days. Bring to room temperature before serving for the best texture.
- Freezer: Wrap slices individually and freeze for up to 2 months. Thaw at room temperature, then refresh with a little extra glaze if desired.
Health Benefits
While this is a treat, it does bring a few positives. Lemons provide vitamin C, which supports immune function and brightens flavor without extra fat.
Using a traybake format helps with portion control—clean, even squares make serving sizes easy to stick to. You can also reduce sugar in the glaze slightly without harming the structure. Pairing a slice with fruit or yogurt makes a balanced dessert or snack.
Pitfalls to Watch Out For
- Overmixing the batter: This can make the cake dense.Mix just until combined after adding the dry ingredients.
- Cold ingredients: Cold butter and eggs won’t incorporate well. Room temperature ingredients whip better and trap air.
- Thin glaze: If the glaze is too runny, it won’t set. Add more icing sugar until it lightly coats the back of a spoon.
- Overbaking: Even a few extra minutes can dry it out.Start checking at 22 minutes and look for a clean skewer.
- Skipping the poke-holes: They help the glaze soak in and keep the crumb moist and lemony.
Recipe Variations
- Lemon Blueberry Traybake: Fold 1–1 1/2 cups fresh blueberries into the batter. Toss them with 1 tbsp flour first to prevent sinking.
- Lemon Poppy Seed: Add 2 tbsp poppy seeds for a lightly nutty crunch and classic combo.
- Lighter Version: Swap half the butter for plain Greek yogurt. Expect a slightly denser crumb but great moisture.
- Gluten-Free: Use a 1:1 gluten-free flour blend with xanthan gum.Check for doneness a few minutes earlier, as textures can vary.
- Extra Tangy: Add 1–2 tbsp limoncello to the glaze for adults-only flair, or simply increase lemon zest in the batter.
- Cream Cheese Frosting: Skip the glaze and top the cooled cake with a light lemon cream cheese frosting for a richer finish.
FAQ
Can I use bottled lemon juice instead of fresh?
Fresh juice gives the brightest flavor and pairs with the zest for a clean citrus taste. Bottled juice can work in the glaze in a pinch, but the cake itself tastes best with fresh lemons.
What if I only have self-raising flour?
Use the same weight of self-raising flour and reduce the baking powder to 1/2 tsp. Keep the salt as written for balance.
How do I know when the cake is done?
Look for light golden edges, a center that springs back, and a skewer that comes out clean or with a few moist crumbs.
If the middle still looks shiny or wobbly, give it a few more minutes.
Can I make this dairy-free?
Yes. Swap the butter for a good dairy-free baking spread and use a plant-based milk like oat or almond. The texture will still be soft and tender.
Why did my cake sink in the middle?
Common causes are underbaking, opening the oven door too early, or too much leavening.
Measure baking powder accurately and avoid peeking for the first 20 minutes.
How can I reduce the sweetness?
Cut the sugar in the batter by 10–15% and use a slightly tarter glaze by increasing the lemon juice. Don’t reduce the sugar too much or the texture may become dry.
Can I bake this in a smaller or larger pan?
You can use a 10×10-inch pan for a thicker cake; add a few minutes to the bake time. A larger pan will yield a thinner cake; check for doneness earlier.
Is it okay to freeze the cake with the glaze?
Yes.
The glaze freezes well and helps protect the crumb. Wrap slices tightly to avoid freezer burn and thaw at room temperature.
