This lemon raspberry loaf cake pairs a soft, buttery lemon crumb with pockets of tart berries and a bright glaze. It is simple enough for an afternoon bake, polished enough for brunch, and slices neatly once fully cooled.
The batter gets its lemon flavor from zest and fresh juice rather than extract. Greek yogurt keeps the crumb tender, while coating the raspberries in a little of the measured flour helps them stay suspended instead of collecting at the bottom.
Why You’ll Love This Lemon Raspberry Loaf Cake
- Fresh, balanced flavor: lemon keeps the buttery cake bright, and raspberries add a gentle tartness.
- Soft but sliceable: yogurt adds moisture without making the loaf heavy or gummy.
- Flexible berries: fresh or frozen raspberries both work, so the recipe is useful year-round.
- Make-ahead friendly: the flavor settles beautifully after the glaze has set.
Before You Start
Use a light-colored 9 × 5-inch loaf pan for the most even bake. Dark pans brown the edges faster, so begin checking a few minutes early. Bring the butter, eggs, and yogurt to room temperature; ingredients at a similar temperature combine more smoothly and help create an even crumb.
Ingredients That Matter
Lemon zest and juice do different jobs here. The zest carries fragrant citrus oils into the batter, while the juice sharpens both the cake and the glaze. Rub the zest into the sugar before mixing to release more aroma.
Greek yogurt contributes moisture and a slight tang. Full-fat or 2% plain yogurt gives the most reliable texture. Sour cream can replace it in the same quantity.
Raspberries should be dry before they enter the batter. If using frozen berries, add them straight from the freezer and expect the loaf to need several additional minutes in the oven.
How to Keep the Loaf Tender
Cream the butter and lemon sugar until visibly lighter, then add the eggs one at a time. Once the flour goes in, mix only until the last dry streaks disappear. Overmixing at that stage develops too much gluten and can make the finished loaf firm instead of tender.
Fold the raspberries in gently with a flexible spatula. A few berries may break and streak the batter; that is perfectly fine and gives the slices their natural raspberry swirls.
How to Know When It’s Done
The top should be golden and spring back lightly when touched near the center. A skewer inserted into a berry-free area should come out with a few moist crumbs but no wet batter. If the loaf is browning before the center is ready, tent it loosely with foil for the final 10 to 15 minutes.
Variations and Substitutions
- Replace the raspberries with the same weight of blueberries or chopped strawberries.
- Use sour cream instead of Greek yogurt in an equal amount.
- Add 1 tablespoon of poppy seeds for a lemon-poppy variation.
- For a lighter finish, skip the glaze and dust the cooled loaf with powdered sugar just before serving.
Storage and Freezing
Keep the glazed loaf covered at room temperature for up to 2 days or refrigerate it for up to 5 days. Let chilled slices sit at room temperature for 15 to 20 minutes before serving for the softest texture.
To freeze, wrap the unglazed loaf or individual slices tightly and store for up to 2 months. Thaw overnight in the refrigerator, bring to room temperature, then add the glaze.
Frequently Asked Questions
Can I use frozen raspberries?
Yes. Keep them frozen, coat them with the reserved flour, and fold them into the batter just before it goes into the pan. The loaf may need 3 to 5 extra minutes of baking time.
Why did my raspberries sink?
Very wet berries, thin batter, or vigorous mixing can all encourage sinking. Dry fresh berries well, keep frozen berries frozen, coat them lightly in flour, and fold them in gently.
Can I glaze the loaf while it is warm?
Wait until it is completely cool. Glaze placed on a warm loaf melts into a thin, translucent layer instead of setting on top.
Recipe

A soft lemon loaf with juicy raspberries and a fresh lemon glaze, baked in a 9 × 5-inch pan.
- Prep Time: 25 minutes
- Cook Time: 60 minutes
- Total Time: 175 minutes
- Yield: 10 slices
- Category: Dessert
- Method: Baking
- Cuisine: American
Ingredients
- 190 g (1 1/2 cups) all-purpose flour, divided
- 1 1/2 teaspoons baking powder
- 1/2 teaspoon fine salt
- 150 g (2/3 cup) unsalted butter, softened
- 180 g (scant 1 cup) granulated sugar
- Finely grated zest of 2 lemons
- 2 large eggs, at room temperature
- 120 g (1/2 cup) plain Greek yogurt, at room temperature
- 30 ml (2 tablespoons) fresh lemon juice
- 1 teaspoon vanilla extract
- 150 g (1 1/4 cups) fresh or frozen raspberries
- 120 g (1 cup) powdered sugar
- 22 ml (1 1/2 tablespoons) fresh lemon juice, plus more as needed
- 1 teaspoon milk, optional for thinning
Instructions
- Prepare the pan: Heat the oven to 350°F (175°C). Grease a 9 × 5-inch loaf pan and line it with parchment, leaving an overhang on the long sides.
- Combine the dry ingredients: Whisk the flour, baking powder, and salt together. Reserve 1 tablespoon of this mixture for the raspberries.
- Make lemon sugar: Rub the lemon zest into the granulated sugar with your fingertips until fragrant and pale yellow.
- Cream the butter: Beat the softened butter and lemon sugar for 2 to 3 minutes, until lighter and fluffy. Beat in the eggs one at a time, scraping the bowl after each addition.
- Finish the batter: Mix in the yogurt, 2 tablespoons lemon juice, and vanilla. Add the dry ingredients and mix on low only until a few flour streaks remain.
- Add the raspberries: Toss the raspberries with the reserved flour. Fold them gently into the batter, then spread the batter evenly in the prepared pan.
- Bake and cool: Bake for 55 to 65 minutes, until golden and a skewer inserted away from a berry comes out with a few moist crumbs. Cool in the pan for 15 minutes, then lift onto a rack and cool completely.
- Glaze: Whisk the powdered sugar with 1 1/2 tablespoons lemon juice. Add a little more juice or the optional milk until thick but pourable. Spoon over the cooled loaf and let the glaze set before slicing.
Notes
For frozen raspberries, do not thaw before folding them into the batter. If the top browns quickly, tent the loaf loosely with foil for the final 10 to 15 minutes.
