Quick Summary

• Soft, buttery crumb

Why This Lemon Raspberry Loaf Cake Works

• Rich buttery flavor
  Butter gives this loaf a soft, tender crumb and a classic cake flavor that pairs beautifully with lemon.
• Buttermilk keeps it extra moist
  Buttermilk adds a slight tang and helps create a soft, fluffy texture without making the loaf heavy.
• Bright lemon flavor in every bite
  Fresh lemon juice and zest give the cake its fresh citrus flavor, which perfectly complements the berries.
• Juicy raspberries throughout
  The raspberries add little bursts of tartness that balance the sweetness and add flavor.

Ingredients & Tips

This lemon raspberry loaf cake uses simple ingredients you may already have in your kitchen. Here are the key ones and a few helpful tips before you start baking.

Key Ingredients

• Butter: Use softened, room temperature butter so it creams properly with the sugar. 
• Lemon Juice & Zest: Fresh lemon juice works best, but the zest is what really gives this cake its beautiful lemon flavor. Rub the lemon zest into the sugar before mixing to release the natural oils.
• Buttermilk: Buttermilk keeps the crumb soft and tender without making the cake heavy.
• Raspberries (Fresh or Frozen): This recipe works with either. If using frozen raspberries, don't thaw them first. Toss them lightly with cornstarch just before adding to the batter to prevent excess moisture.
• Powdered sugar: Used to make the simple lemon glaze. Lemon juice gives it light citrus flavor, while a little milk helps balance the sweetness and create a smooth drizzle.

How to prevent raspberries from sinking

Raspberries can easily sink to the bottom of a loaf cake, especially when using large or frozen berries. After testing several different methods, I found that this approach works best:

First, the raspberries are lightly coated in cornstarch to help absorb surface moisture.

Next, most of the batter is added to the pan before the raspberries. Placing the fruit slightly higher in the loaf helps reduce sinking.

Finally, the cake starts baking at a higher temperature for the first 15 minutes. This helps the structure set early and supports the fruit.

Equipment you'll need

• 8×4-inch (20x10 cm) loaf pan
• mixing bowls
• hand mixer or stand mixer
• rubber spatula
• cooling rack

How to Make Lemon Raspberry Loaf Cake

Step 1: Make the Lemon Sugar

Rub the granulated sugar and lemon zest together with your fingers in a small bowl until the sugar becomes fragrant and slightly damp. This helps release the natural oils from the zest for stronger lemon flavor.

Step 2: Mix the Dry Ingredients

In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.

Step 3: Cream the Butter and Lemon Sugar

Beat the softened butter in a large mixing bowl for about 1 minute until smooth. Add the lemon sugar and beat on medium speed for 3-4 minutes, until the mixture becomes light and fluffy.

Step 4: Add the Eggs, Lemon Juice and Vanilla

Beat in the eggs one at a time, mixing well after each addition. Add the lemon juice and vanilla extract and mix until combined.

Step 5: Alternate the Flour and Buttermilk

Add half of the flour mixture and half of the buttermilk to the batter and mix just until combined. Repeat with the remaining flour mixture and buttermilk and mix gently.

Step 6: Coat the Raspberries

Place the raspberries in a small bowl and gently toss them with the cornstarch.

Step 7: Add Most of the Batter to the Pan & Top with Raspberries

Spoon about three-quarters of the batter into the prepared loaf pan and spread it evenly. Scatter most of the coated raspberries over the batter, reserving about 6-8 raspberries for the top of the loaf in the next step.

Step 8: Add the Remaining Batter and Raspberries

Spoon the remaining batter over the top and gently spread it to cover the berries. Dot the reserved raspberries over the surface.

Step 9: Bake the Loaf

Bake the cake until golden.

Variations

Use a 9x5-inch (23×13 cm) Loaf Pan

You can bake this in a 9×5-inch (23×13 cm) loaf pan instead of an 8×4-inch (20×10 cm). The loaf will be slightly shorter and may bake a little faster, so start checking for doneness 5-10 minutes earlier.

Add a Streusel Topping

For a bakery-style variation, you can add a crumb topping before baking instead of glazing. Use the streusel from my Easy Cinnamon Streusel Muffins recipe and sprinkle it evenly over the batter before baking.

Skip the Glaze

If you prefer a less sweet loaf, you can leave off the glaze and dust the top lightly with powdered sugar instead.

Storage Tips & Freezing Instructions

Store the loaf in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 5 days. 

Freezing Instructions
This loaf freezes really well, with or without the glaze.

Let the cake cool completely first. Then slice it if you prefer freezing individual portions.

My usual method:
I place the slices on a tray and flash freeze them for about 1 hour until firm (this keeps them from sticking together). Then I wrap each slice in plastic wrap and place them in a freezer bag or freezer-safe container. This way, you can easily grab one slice at a time.

The loaf will keep well in the freezer for up to  about 2 months. To thaw, just leave a slice in the refrigerator overnight. You can keep it wrapped in the bag while it thaws.
