I love a lemon loaf because it brightens an ordinary afternoon and takes under an hour to bake. This version is straightforward: a tender, citrus-scented cake finished with a soaking lemon drizzle and a smooth lemon icing. It’s the kind of recipe you can rely on when you want something pretty and reliable without fuss.

I’ll walk you through what you need, step-by-step instructions, and practical tips I’ve learned from making this loaf dozens of times. There are troubleshooting notes and easy swaps at the end so you can adapt the loaf to what you have in the kitchen.

What You’ll Gather

Ingredients

125gm Kerrygold salted butter — brings richness and a slight salty balance to the lemon; room temperature for easier creaming.
225gms caster sugar — main sweetener; helps the cake brown and keeps texture light when creamed with butter.
Zest of 2 large lemons or 3 medium — concentrated lemon flavor; zest before juicing so you don’t waste any.
½tsp vanilla extract — rounds the citrus and lifts the overall flavor.
2large free-range eggs — provide structure and moisture; add one at a time so the batter emulsifies.
280gms flour — all-purpose is assumed; gives the cake its body—measure by spooning into the cup and leveling or weigh for accuracy.
2tsp baking powder — the leavening agent; make sure it’s fresh for a good rise.
115gms full fat or double cream Greek yoghurt — adds moisture, tenderness, and a slight tang; bring to room temperature if refrigerated.
40gms caster sugar — for the lemon drizzle; dissolves into the lemon juice to sweeten and soak the cake.
3Tbsplemon juice — mixed with the 40gms sugar to make the soaking drizzle; use freshly squeezed for best brightness.
150gms icing sugar sifted — base for the lemon icing; sifting avoids lumps and gives a glossy finish.
2– 3 Tbsp lemon juice — added to the icing to reach the right consistency; start with 2 tbsp and add more if needed.

Cooking lemon loaf cake with lemon glaze: The Process

Preheat your oven to 180°C (350°F). Line a 22 x 12 cm loaf tin with baking paper so the cake releases easily.
In a large mixing bowl, use an electric mixer to beat 125gm Kerrygold salted butter and 225gms caster sugar together until the mixture is pale and fluffy, about 3–5 minutes. Add the lemon zest and ½tsp vanilla extract and beat briefly to combine.
Add the 2 large free-range eggs one at a time, beating well after each addition. Scrape down the bowl between additions to ensure everything is fully incorporated.
With the mixer set to low, add the 115gms full fat or double cream Greek yoghurt and the dry ingredients in 2 or 3 additions: mix in 280gms flour and 2tsp baking powder together, then add them gradually, mixing only until just combined. You can fold by hand with a spatula if you prefer—do not overmix.
Scrape the batter into the prepared loaf tin and spread it evenly to the edges so it bakes flat and uniformly.
Bake on the middle rack for 40–45 minutes, until the top is golden brown and the cake feels firm to the touch. Test doneness by inserting a sharp knife or skewer into the center—if it comes out clean, the cake is done. If the top is browning too quickly, loosely tent the cake with foil for the remaining bake time.
While the cake bakes, make the lemon drizzle: combine 40gms caster sugar with 3 Tbsp lemon juice in a small bowl, stirring until the sugar dissolves.
When the cake comes out of the oven, immediately poke it all over with a sharp knife or skewer to create holes for the drizzle. Brush or spoon the lemon drizzle evenly over the hot cake, allowing it to soak in.
Leave the cake in the tin for 10 minutes to set, then remove it and transfer to a wire rack to cool completely.
Once the cake is completely cool, make the icing by mixing 150gms sifted icing sugar with 2–3 Tbsp lemon juice. Start with 2 Tbsp, whisk to a smooth, spreadable consistency, and add the extra tablespoon if you want a thinner glaze that drips more down the sides.
Spread the lemon icing over the cooled loaf and allow some to drip naturally down the edges. Let the icing set for at least 15–20 minutes before slicing.

Why I Love This Recipe

This loaf hits the sweet-tart balance perfectly: lemon zest folded into the batter means the lemon flavor is everywhere, while the drizzle and icing layer amplify that freshness without making the cake soggy. It’s forgiving—mix gently and it performs. The texture is tender but sturdy enough to slice for tea, picnics, or an afternoon pick-me-up.

It’s also fast to put together and uses pantry basics with one specialty item: good butter. Using a full-fat Greek yoghurt keeps the crumb moist and adds a subtle tang that pairs beautifully with citrus, so the cake never feels cloying.

Ingredient Swaps & Substitutions

Butter — if you don’t have Kerrygold, use any unsalted butter and add a pinch of fine salt to the batter.
Caster sugar — granulated sugar works in a pinch; pulse briefly in a blender to make it finer if needed.
Greek yoghurt — sour cream is an excellent substitute; buttermilk will also work—reduce by a tablespoon if it seems very loose.
Flour — all-purpose is expected. For a slightly denser but tender loaf, you can try half plain flour and half white spelt flour.
Icing sugar + lemon juice — if you want a thicker glaze, use only 2 Tbsp lemon juice; add a teaspoon of milk if you prefer a shinier finish.

Kitchen Gear Checklist

22 x 12 cm loaf tin (lined with baking paper)
Electric mixer (or wooden spoon and elbow grease for creaming)
Mixing bowls
Sieve for icing sugar
Kitchen scale (recommended) or measuring cups
Wire rack for cooling
Sharp knife or skewer for poking the hot cake
Spatula for folding and spreading

Things That Go Wrong

Top browning too fast — tent loosely with foil during the last 15–20 minutes of baking.
Cake sinks in the center — likely underbaked or the oven temperature was too low/too high; always check with a skewer.
Dry, crumbly texture — overmixing or too much flour; measure flour by weight to avoid this.
Icing too runny — add more sifted icing sugar a tablespoon at a time until desired thickness.

Seasonal Twists

Spring: Fold in a tablespoon of poppy seeds with the dry ingredients for a classic lemon-poppy variation.
Summer: Top with fresh berries like raspberries or blueberries when the icing is tacky so they stick and lend a fresh note.
Autumn: Swap half the lemon zest for orange zest and add a pinch of ground cardamom for warmth.
Winter: Add 1 tsp finely grated ginger to the batter and finish with candied ginger pieces on top of the icing.

What Could Go Wrong

Dense or heavy cake — caused by overmixing once the flour is in or cold ingredients. Let eggs and yoghurt sit at room temperature for 20–30 minutes before starting.
Undercooked center — ovens vary. If the skewer comes out with wet batter, bake in 5–7 minute increments until clean.
Soggy bottom from too much drizzle — poke holes, but don’t pour all the drizzle in one spot; spread it across the top so it soaks evenly.

Keep-It-Fresh Plan

Room temperature: store the loaf in an airtight container for up to 2 days.
Refrigerator: if your kitchen is warm, keep the glazed loaf covered in the fridge for up to 5 days. Bring to room temp before serving for the best texture.
Freezing: wrap whole cooled loaf tightly in plastic and foil; freeze up to 3 months. Thaw overnight in the refrigerator then warm gently before serving.
