One-Bowl Lemon Raspberry Loaf Cake with a Tangy Glaze
This lemon raspberry loaf cake is the kind of dessert you can pull off on a Tuesday night and still serve to company on Saturday. It comes together in one bowl, no mixer needed, and bakes into a soft, tangy loaf studded with juicy raspberries.
A simple lemon glaze seals the top, cracking just enough when you slice to promise a moist crumb underneath. It walks that line between sweet and sharp, and somehow tastes even better the next day.
What Makes This Loaf Cake a Go-To
The batter comes together in under 10 minutes without dragging out a stand mixer. That alone keeps it in heavy rotation when I need a dessert fast.
The real payoff is the texture. The loaf stays incredibly soft thanks to the yogurt, and the raspberries burst into jammy pockets throughout. The lemon glaze adds a crackly top that makes slicing deeply satisfying.
It is also one of those rare cakes that improves overnight. The lemon gets deeper, the crumb settles, and it is still tender the next afternoon.
Ingredients
- 1 ½ cups (190 g) all-purpose flour: spoon and level the flour for an accurate measure.
- 2 tsp baking powder: check the expiry date for the best rise.
- ½ tsp salt: fine sea salt.
- 1 cup (200 g) granulated sugar
- 2 large eggs: at room temperature so they blend smoothly.
- ½ cup (120 ml) neutral oil: vegetable or canola oil keeps the crumb soft.
- ½ cup (120 g) plain yogurt or sour cream: full-fat for richness and tang.
- 2 tbsp lemon zest: roughly 2 to 3 lemons.
- 3 tbsp fresh lemon juice: from the same lemons.
- 1 tsp vanilla extract
- 1 ½ cups fresh raspberries: if using frozen, do not thaw them first.
- For the glaze:
- 1 cup (120 g) powdered sugar: sifted if lumpy.
- 2 to 3 tbsp fresh lemon juice: enough to make a thick but pourable glaze.
Variations and Substitutions
- Swap the fruit: blueberries or blackberries work beautifully in the same amount. Keep them whole.
- Make it dairy-free: use a thick plant-based yogurt and skip the regular yogurt. The crumb will be slightly different but still tender.
- Go gluten-free: a 1:1 gluten-free flour blend that contains xanthan gum will work. The loaf might need 2 to 3 extra minutes in the oven.
- Lime instead of lemon: lime zest and juice bring a brighter, slightly more floral note. It is a lovely change.
- Add a crumble topping: scatter a simple streusel of flour, butter, and sugar over the batter before baking for a crisp top layer.
- If this one hits the spot for you, my lemon blueberry bundt cake is another favorite with the same bright flavors.
How to Make Lemon Raspberry Loaf Cake
Step 1: Mix the Wet Ingredients
In a large mixing bowl, whisk the 1 cup sugar and the 2 large eggs together until the mixture lightens in color and thickens slightly, about 1 minute of steady whisking. Pour in the ½ cup oil, the ½ cup yogurt, the 2 tbsp lemon zest, the 3 tbsp lemon juice, and the 1 tsp vanilla. Whisk until you have a smooth, pale batter with no streaks of oil.
The batter at this stage will look glossy and smell intensely of lemon. If your eggs were cold, the mixture may seem a little thick, but it will loosen up once the dry ingredients join in.
Step 2: Fold in the Dry Ingredients and Raspberries
Set a sieve over the bowl and add the 1 ½ cups flour, the 2 tsp baking powder, and the ½ tsp salt. Sift them straight onto the wet mixture, then use a spatula to fold everything together with a light hand. Switch to a gentle folding motion as soon as most of the flour disappears. Stop the moment no pockets of dry flour remain, which should take about 20 to 30 seconds.
Drop the 1 ½ cups raspberries onto the batter. Use the spatula to fold them in with only 3 or 4 strokes so they distribute without crushing. The batter will be thick enough to hold the berries suspended.
Step 3: Bake the Loaf
Preheat your oven to 350°F (175°C) and position a rack in the center. Grease a 9×5-inch loaf pan and line it with a strip of parchment paper that hangs over the two long sides for easy lifting. Pour the batter into the pan and nudge it into the corners with the spatula. Smooth the top gently so it is even.
Slide the pan into the oven and bake for 50 to 55 minutes. Around the 45-minute mark, check the top. It should be deeply golden and a toothpick inserted in the center should come out with a few moist crumbs clinging to it. Let the cake cool in the pan on a wire rack for 10 minutes, then lift it out using the parchment and set it directly on the rack to cool completely.
Step 4: Whisk the Glaze
While the cake cools, place the 1 cup powdered sugar in a small bowl. Add 2 tbsp of the lemon juice and whisk until the sugar dissolves. Drizzle in a little more juice, ½ tsp at a time, until the glaze flows in thick ribbons from the whisk but still holds its shape for a second before melting into the bowl.
The glaze should be opaque and smooth. If you overshoot and it turns watery, stir in an extra spoonful of powdered sugar to bring it back.
Step 5: Glaze and Slice
Set the cooled loaf on a serving plate or a sheet of parchment. Use a spoon to pour the glaze down the center of the cake, letting it run over the sides in uneven drips. Resist the urge to spread it with a knife. Let the glaze set for about 15 minutes, until it firms into a thin, crackly shell.
Slice with a serrated knife, wiping the blade between cuts for the cleanest pieces. The first slice always reveals those jammy red pockets and the soft, sunny crumb underneath.
A Few Keys to the Best Loaf Cake
- The cake rises best when your eggs and yogurt are at room temperature. If you forgot to pull them from the fridge, set the eggs in a bowl of warm tap water for 5 minutes and microwave the yogurt in short bursts until it loses its chill.
- A metal loaf pan in a light finish gives the most even browning. Dark metal or glass can cause the edges to brown too quickly, so check for doneness 5 minutes earlier if that is what you have.
- Overmixing once the flour is in will turn the crumb tough. Fold just until no white streaks remain, then stop.
- Let the cake cool completely before glazing, or the glaze will melt and soak straight into the loaf. A warm cake is fine if you want a thin, translucent glaze that seeps in, but the crackly top needs a cool cake.
- The glaze adjusts in seconds. If it is too thick, add lemon juice a few drops at a time. Too thin, stir in more powdered sugar.
Bake times by pan size and material:
| Pan | Material | Bake Time |
|---|---|---|
| 9×5-inch | light metal | 50 to 55 minutes |
| 9×5-inch | glass | 55 to 60 minutes |
| 8×4-inch | light metal | 45 to 50 minutes |
Storing Leftover Cake
- Refrigerate: wrap the glazed loaf tightly in plastic wrap or keep it in an airtight container in the fridge for up to 4 days. The chill firms the crumb and makes neat slices even easier.
- Reheating: a 10 to 15 second zap in the microwave per slice brings back that fresh-from-the-oven softness without melting the glaze too much.
- Serve cold: the cake is delicious straight from the fridge, especially on a warm day.
Frequently Asked Questions
Why did my raspberries sink to the bottom?
Fresh raspberries are heavy and the batter is fluid enough that they can drift down. Toss the berries in just 1 tbsp of flour from your measured amount before folding them in. That added grip holds them in place.
Can I bake this in a bundt pan?
Yes, a 6-cup bundt pan works. Grease it very well and expect a deeper shape. Start checking for doneness at 40 minutes, as the center cooks differently.
Can I double the recipe?
Absolutely. Use a 10-cup tube pan or two 9×5-inch loaf pans. The bake time will be roughly the same, but rely on the toothpick test rather than a clock.
Does the glaze need refrigeration?
The glaze sets firm and is mostly sugar, so a glazed cake is fine at room temperature for a day. Beyond that, keep it in the fridge for freshness.
