Hi there! It’s Fiona stopping in from Just So Tasty, and today I’m sharing this Lemon Poppy Seed Cake with Cream Cheese Frosting.

From Poppy Seed Muffins to Cake!

It’s a soft, buttery, perfectly moist lemon cake that’s dotted with poppy seeds and topped with cream cheese frosting. It’s one of my favorite cakes, and it’s the perfect dessert if you love lemon poppy seed muffins.

The inspiration for this cake came after a friend gifted us with a poppy seed roll. It was a yeast bread with a swirl of poppy seed filling, and absolutely delicious. As I was having a slice with a thick slather of butter, it got me thinking about poppy seed recipes and I realized I hadn’t made any in a very long time.

So – this lemon poppy seed cake was born.

We have an entire video of exactly how to make it, so check it out!

For the Lemon Poppy Seed Cake

The lemon poppy seed cake starts with real butter for extra flavor. We’ll cream together the butter and sugar, then mix in the eggs and vanilla. Then we’ll alternate between adding in the sour cream and the dry ingredients. And finally the lemon juice, lemon zest and poppy seeds are stirred in.

How to Make Your Cake Moist

For this lemon cake, we’re using sour cream because it makes the cake crumb oh so soft and perfectly moist. Just make sure it’s room temperature for easy mixing.

Then for the best lemon flavor, we’re using a combination of freshly squeezed lemon juice and lemon zest. Make sure that you don’t use lemon juice from the bottle, otherwise the flavor will be too sour.

For the Cream Cheese Frosting

After the cake is done baking and cooled, it’s time to make the cream cheese frosting. Simple, creamy, a little tangy, and the perfect pairing for this lemon cake. We’ll first beat together the cream cheese and butter, then slowly add in the powdered sugar along with a little vanilla extract and lemon juice.

You’ll want to make sure both the butter and cream cheese are well softened to avoid lumps in the frosting, but otherwise it comes together with very little effort.

Can You Freeze Poppy Seed Cake With Cream Cheese Frosting?

You can freeze Lemon Poppy Seed Cake with Cream Cheese Frosting.

Cream cheese frosting  is ideal for freezing.

It is sturdy, with plenty of fat, and it will do better in the freezer than a more delicate meringue-based icing.

Just wrap the cake well and freeze.

Thaw before serving.

OR You can freeze the cake before it is frosted. Wrap your cooled cake in plastic food wrap.

Then wrap in tin foil or place in a plastic freezer bag and remove the air.

Thaw the cake completely and then frost.  

Do Poppy Seeds Have Nutritional Value?

Poppy seeds add color and crunch to baked goods, but you’ll also gain nutrients, even from the amount sprinkled on top of a roll. They contain some niacin and folate, but poppy seeds are a better source of minerals. Just 1 teaspoon provides measurable amounts of calcium, iron and zinc.

I brought this lemon poppy seed cake with cream cheese frosting over to a family dinner, and there wasn’t even a tiny sliver left over. It’s buttery, moist, filled with fresh lemon flavor, and the cream cheese frosting is everything that you’d want it to be. Seriously – if you love lemon, you need to try this cake!

Does a Glass Dish Require More Cooking Time Than Metal?

A reader recently asked if her cake pan that is a glass dish requires more cooking time than a metal dish does and as it’s such a good question I wanted to mention it here.

Glass heats up slower but holds on to heat longer, so you may require a little more baking time. To help us not over bake this cake we like to open the oven at the end and let the glass dish cake rest for up to 4 minutes more before removing it from the oven to cool.
