Raspberry-Lemon-Poppy Seed Loaf

Recipe Ingredients

Let's break down the ingredients needed for this Raspberry-Lemon-Poppy Seed Loaf.

Yellow Cake Mix: This is your fantastic shortcut to a consistently moist and tender cake base.

Whole Milk Vanilla Yogurt: Yogurt adds richness, a subtle tang, and helps create a soft texture.

Unsalted Butter: Butter brings a rich, classic flavor and contributes to the loaf's tender crumb. Melting it helps it incorporate smoothly into the batter.

Eggs: Eggs are essential binders, helping to hold the loaf together.

Lemon Zest: Lemon zest contains aromatic oils that infuse the entire loaf with a fresh, vibrant citrus note.

Poppy Seed: These tiny seeds add a subtle crunch and a unique, nutty flavor.

Raspberries: Fresh raspberries provide a burst of sweet-tart flavor and vibrant color.

Granulated Sugar: Balances the tartness of the raspberries, enhancing their natural sweetness and helping the filling thicken slightly.

Cornstarch: This is a thickening agent for your raspberry filling. It prevents the berries from making the loaf soggy and helps create that lovely, slightly jammy texture.

Powdered Sugar: Powdered sugar dissolves easily, creating a smooth, sweet finish for your loaf.

Lemon Juice: This is what gives the icing its bright, tangy lemon flavor and helps achieve the perfect drizzling consistency.

How to Make Raspberry-Lemon-Poppy Seed Loaf

Here's how to make this delicious Raspberry-Lemon-Poppy Seed Loaf in just four simple steps with some key pointers for success. See the full recipe below for all the details.

1. Prepare Batter & Pan

When combining the loaf ingredients don’t overmix. Overmixing can develop the gluten too much, leading to a tougher, less tender loaf. Spraying your loaf pan thoroughly with baking spray with flour (or greasing and flouring) ensures that your loaf will release easily from the pan without sticking or tearing.

2. Make Raspberry Filling 

Thicken your raspberry filling properly. Microwaving the raspberries with sugar and cornstarch until it thickens slightly prevents the filling from becoming too watery and making your loaf soggy. Make sure it's bubbly and slightly jammy before spreading.

3. Assemble & Bake 

Keep an eye on your loaf towards the end of the baking time. Bake until it's golden brown and a toothpick inserted into the center comes out clean. Overbaking will dry out your loaf, making it less moist and delicious.

4. Cool & Glaze

It's tempting to drizzle that delicious lemon icing right away, but patience is key! If the loaf is still warm, the icing will melt and run off, rather than setting into a nice glaze. Allow the loaf to cool completely on a wire rack for at least an hour.

How to Store Raspberry-Lemon-Poppy Seed Loaf

To keep your Raspberry-Lemon-Poppy Seed Loaf fresh and delicious, here's how to store it.

Room Temperature 

Once the loaf has completely cooled and the icing has set, store it in an airtight container at room temperature. This will prevent it from drying out. It will stay fresh for up to 4 days.

Freezer

Wrap the cooled, un-iced loaf tightly in plastic wrap, then in aluminum foil. If it's already iced, you can still freeze it, but the icing might become a little softer upon thawing. Store in the freezer for up to 3 months. Thaw it overnight in the refrigerator or at room temperature before serving.
