Lemon Drizzle Traybake Poppy

There's something about a lemon drizzle cake that instantly transports me back to my nan's kitchen on a grey British afternoon, the kind where rain taps against the window and the whole house smells like butter and sugar melting together. She'd pull one of these golden squares from the tin still warm, the glaze still glistening, and hand it to me with a knowing smile—no fancy plating, just honest, zesty comfort. I've made this traybake more times than I can count now, tweaking it here and there, but that first taste of the sharp lemon hitting the sweet sponge never gets old. It's become my go-to when I need something that feels effortless but tastes like I've actually tried.

I remember bringing this to a village bake sale years ago, nervous it was too simple compared to the elaborate layer cakes everyone else had brought. A woman in her eighties picked up one of my squares, took a bite, and said it tasted exactly like the ones her mother made in the 1950s—and suddenly I understood that simplicity was the whole point. Comfort doesn't need to be complicated, and sometimes the most memorable food is the food that feels like home.

Ingredients

• 225 g unsalted butter, softened: This is the foundation—soft butter creams better with sugar, creating the air pockets that make the cake light and tender, not dense.
• 225 g caster sugar: The fine crystals dissolve faster than granulated sugar, which helps create that pale, fluffy texture when creamed with butter.
• 4 large eggs: Room temperature eggs blend more smoothly into the batter; cold ones can cause the mixture to split.
• 250 g self-raising flour: The rising agent is already built in, which is why this cake needs no baking powder or baking soda—just fold gently to keep the air you've whisked in.
• 2 tbsp poppy seeds: Toast them lightly in a dry pan first if you want to wake up their subtle, slightly nutty flavor before stirring them in.
• Zest of 2 lemons: Use a microplane grater to get fine zest without the bitter white pith; this is where the real lemon magic lives.
• 2 tbsp milk: This loosens the batter slightly, making it easy to spread evenly in the tin without overmixing the flour.
• 1 tsp vanilla extract: It rounds out the tartness of the lemon and adds a whisper of warmth to the background.
• ¼ tsp fine salt: A pinch of salt brightens the lemon flavor and balances the sweetness so the cake doesn't taste one-dimensional.
• Juice of 2 lemons: Freshly squeezed is non-negotiable here; bottled juice tastes thin and chemical by comparison.
• 100 g icing sugar: Sifted with the lemon juice, it creates a glaze that's pourable and glossy, not lumpy and dull.

Instructions

Get your oven ready and prep the tin:

Preheat to 180°C (160°C fan) / 350°F and line a 23 x 33 cm traybake tin with baking parchment, letting it hang slightly over the edges so you can lift the whole cake out later. This stops the edges from browning too fast and gives you something to grip.

Cream the butter and sugar:

Beat them together for about 3-4 minutes until the mixture is pale, fluffy, and light enough to leave a trail when you lift the beaters. Don't rush this step—it's where the cake gets its tender crumb.

Add the eggs one at a time:

Beat each egg in fully before adding the next; this prevents the batter from looking split and grainy. If it does curdle slightly, add a tablespoon of flour to bring it back together.

Fold in the dry ingredients gently:

Sift the flour with the salt, then fold it in along with the poppy seeds, lemon zest, and vanilla, using a spatula and cutting down through the middle of the bowl with a gentle twisting motion. Stop as soon as you don't see streaks of flour—overmixing develops gluten and makes the cake tough.

Stir in the milk:

Add it last and fold it through until the batter is smooth and pourable but not thin. It should fall slowly from the spatula.

Pour into the tin and bake:

Spread it evenly using an offset spatula or the back of a spoon, then slide into the oven for 28-32 minutes. The cake is done when it's golden brown and a skewer pushed into the center comes out clean or with just a few moist crumbs clinging to it.

Make the drizzle while it bakes:

Whisk the fresh lemon juice with sifted icing sugar until smooth and pourable; it should be thin enough to soak into the cake but thick enough not to run straight off the sides.

Drizzle while the cake is still hot:

As soon as the cake comes out of the oven, use a skewer to poke holes all over the surface—they give the tart glaze somewhere to soak in. Pour the drizzle evenly over the top and let it pool and seep into those pockets.

Cool and cut:

Let the cake cool completely in the tin—this helps it set properly and makes cutting clean squares much easier. Once cool, lift it out using the parchment, peel away the paper, and cut into 12 squares with a sharp knife dipped in warm water between cuts.

Pin It

Years ago, a friend who claimed she hated homemade cakes because shop-bought ones were 'easier' took a bite of this still-warm from the tin and went quiet. She asked for the recipe that same day, and I realized then that sometimes the simplest things say the most—that you cared enough to spend an afternoon in the kitchen, that the person eating it was worth the effort, even if the effort itself felt easy.

Why Poppy Seeds Matter

Poppy seeds aren't just decoration here—they add a subtle, almost nutty texture that makes you pause and think about what you're tasting. They're tiny, so they don't interrupt the crumb of the cake, but they're there, catching on your tongue, adding visual interest to every slice. If you've ever wondered why a cake tastes 'more' without being able to pinpoint why, it's often because of something small like this—a background note that makes the whole thing feel intentional and thought through.

The Science of Lemon Zest vs. Juice

The zest and juice do different jobs, which is why you need both. The zest holds the oils that give you that bright, floral lemon smell and flavor in the cake itself, while the juice in the drizzle is sharp and tangy, cutting through the sweetness. If you only had one or the other, the cake would taste lopsided—either perfumy without bite or sour without any softness. Together, they're balanced in a way that makes your mouth water and keeps you reaching for another square.

Serving and Storage

This cake tastes best on the day it's made while the drizzle is still slightly sticky and the crumb is at its most tender, but it keeps beautifully wrapped in foil or stored in an airtight container for up to three days. A dollop of crème fraîche or Greek yogurt on top softens the sweetness and adds a creamy contrast that makes it feel almost elegant. Serve it with a pot of Earl Grey tea, and you've got an afternoon that feels like a proper break from the day.

• If you're making this ahead, skip the drizzle until just before serving so it doesn't get stale or weepy.
• Leftover cake toasts beautifully under the grill for a few seconds if it's lost some of its moisture.
• You can substitute the poppy seeds with chia seeds, sesame seeds, or even finely chopped candied lemon peel if you want to switch things up.
