Lemon Poppy Seed Cake is soft, moist, simple to make and loaded with fresh lemon flavor. The lemon buttercream had me licking the spatula, the bowl, the piping bag…

Our love of poppy seed desserts is obvious, from our Poppy Seed Cake to Mom’s Poppy Seed Roll. And the fresh flavor of lemon really amps up desserts, like these lemon-glazed blueberry muffins. The combination of poppy seeds and lemon is pure bliss.

Lemon Poppy Seed Cake Recipe:

Lemon cakes are challenging because they tend to be dry. We made cake after cake until we landed on this combination which produced a moist cake with a soft crumb studded with poppy seeds and subtle and lovely lemon flavor. The softened butter and buttermilk were the key to adding moisture and great flavor to the cake.

Can I Substitute the Fresh Lemon Juice?

Fresh lemon juice is critical in this lemon cake and all you need is a total of 2 large lemons for the cake and frosting. Using both the zest and the juice will give you the best lemon flavor. Lemon juice from concentrate just won’t be the same. We haven’t tried lime but it’s worth experimenting for a lime flavored cake.

Can I Make this Lemon Poppy Seed Cake Ahead?

This Lemon Poppy Seed Cake refrigerates well and we actually prefer it chilled for an hour or so for easier slicing. The little bit of cream cheese in the frosting keeps it from firming up too much in the fridge so you can serve it chilled or at room temperature.

How to Store A Cake:

  • Plain cake layers – cool completely to room temperature then wrap fully in several layers of plastic wrap and keep at room temperature up to 2 days, refrigerate up to 5 days, or freeze up to 3 months.
  • Frosted cakes – cover with a cake keeper (here’s ours) or use a large overturned bowl or even pot (just be sure it has enough clearance for the width and height of the cake. Refrigerate cakes covered to keep them from drying out or absorbing refrigerator odors.
  • Sliced Cake – once a cake has been cut, it starts to lose moisture. To keep it fresh, lay a piece of plastic wrap against the cut side then cover as you would whole frosted cakes (see above).

How to Make Lemon Buttercream:

The secret to the best lemon buttercream frosting is adding just a little bit of softened cream cheese. It balances the flavor, enhances the lemon and makes the texture luxuriously whipped, velvety smooth and perfect for piping onto cakes. A pop of fresh lemon flavor cuts the sweetness and makes it irresistible. This lemon frosting couldn’t get any easier:

  1. Cream butter then beat in cream cheese until smooth
  2. Add powdered sugar, vanilla and fresh lemon juice
  3. Beat 5 minutes on high speed until whipped and fluffy

Pro Cake Baking Tips:

  1. Have all of your moist ingredients at room temperature. Butter, eggs, lemons and buttermilk should be at room temperature before using. Room temperature ingredients incorporate much easier for an even-textured batter and improved rise. When to take ingredients out? Timing depends on your room temperature so take ingredients out at least 1 hour before or 2 hours before to be sure.
  2. Read through the recipe before starting so you know what tools are needed for a recipe and aren’t frantically looking for that whisk when you need it.
  3. Pre-measure everything so it’s ready to add as you follow the recipe.
  4. Measure ingredients correctly – use the correct measuring cups and spoons for wet or dry ingredients. The way you fill matters, i.e. for flour, use the spoon and scrape method instead of plunging your measuring cup into a bin which can give you 25% more flour, resulting in a dense cake.
  5. Keep the oven door closed, opening it only to test for doneness at the end.
