If you’re going to have an iced lemon loaf cake, then you better have an iced lemon poppy seed loaf cake too because lemon and poppy seeds just belong together! I love the added flavor and texture the poppy seeds add.

I love a good loaf cake though, so I had to figure out the perfect recipe for a lemon poppy seed loaf cake. It just looks a little prettier with that glaze over a loaf.

How to Make Iced Lemon Poppy Seed Cake
There are three parts to this recipe, but each step is simple and I’m going to walk you through each part. Here are the basic steps:
For The Cake
- Preheat the oven and grease a loaf pan.
- Combine the sugar and lemon in a bowl and rub it between your fingers to release the oils in the lemon zest.
- Whisk together all the dry ingredients in a bowl. Add the sugar and lemon zest and whisk to combine.
- Whisk the eggs and sour cream together in a small bowl.
- Place the flour mixture and butter in a stand mixer and beat until fluffy.
- Add half the egg mixture and the lemon juice and lemon extract.
- Increase the speed on the mixer and beat until smooth scraping down the sides as needed.
- Add the rest of the egg mixture and beat until combined.
- Using a rubber spatula, fold in the poppy seeds.
- Spread the batter into the loaf pan.
- Bake. While it is baking, prepare the lemon glaze.
For The Glaze
- Melt the butter in a small pan on the stove top.
- Add the sugar and lemon juice and stir to combine.
- Whisk in the vanilla until the sugar is dissolved.
- When the cake is finished, use a toothpick to poke holes all over the cake.
- Pour the glaze all over it.
- Let the cake cool and then turn it out onto a cooling rack. Top with the icing.
For The Icing
- Whisk together all the ingredients for the icing in a small bowl.
- PRO TIP: If you want bright white icing, omit the lemon juice. The icing will be thicker.
- Pour the icing down the center of the cake and spread the icing to cover the cake.
The complete detailed instructions can be found in the recipe card below.
Can Oil Be Used Instead of Butter?
You can substitute vegetable oil for the butter. The cake will be even more moist, but it won’t have a buttery taste. I like the cake both ways, but I’m such a sucker for the buttery goodness!
Does Lemon Poppy Seed Cake Need To Be Refrigerated?
Lemon poppy seed cake can be stored in the pantry, but it will last longer if you refrigerate it.
How Long Will Lemon Poppy Seed Cake Keep?
Lemon poppy seed cake will store well for 3 days at room temperature or 5-6 days in the fridge.
The cake should be covered to store.
Are Poppy Seeds Good For You?
Poppy seeds are a rich source of essential minerals including calcium, iron, and zinc.
It’s lemon and poppy seeds and cake. That’s a trio that I will love forever! You’re going to love this bright and tender iced lemon poppy seed loaf cake. Please invite me to your next spring brunch with the ladies!
