This lemon poppy seed cake brings bright citrus flavor to a tender, moist crumb that's perfect for spring celebrations or afternoon tea. The triple-layer design creates an impressive presentation while the poppy seed-flecked frosting adds both visual appeal and a subtle crunch that complements the vibrant lemon taste.
I discovered this recipe during a family birthday celebration and it's become our go-to cake for special occasions. The bright lemon flavor paired with delicate poppy seeds creates the perfect balance.
Ingredients
- Cake flour: Gives this cake its delicate, tender crumb texture but all purpose flour works perfectly well too
- Fresh lemon zest: Provides essential oils that infuse the sugar with intense citrus flavor
- Buttermilk: Creates tenderness and a slight tang that enhances the lemon
- Lemon paste: Optional but intensifies the citrus flavor wonderfully
- Poppy seeds: Add a delightful crunch and classic pairing with lemon
- Room temperature butter and eggs: Ensure proper emulsion for a perfect cake texture
- Confectioner's sugar: Creates a silky smooth frosting that spreads beautifully
Step-by-Step Instructions
- Prepare the pans:
- Grease and flour three 9 inch baking pans thoroughly, then line the bottoms with parchment paper rounds. This triple protection ensures your cakes will release perfectly after baking. The parchment is particularly important as these delicate layers can stick otherwise.
- Process the lemon sugar:
- Place granulated sugar in a food processor along with carefully peeled lemon zest. Use a serrated vegetable peeler to remove just the yellow outer layer, avoiding the bitter white pith beneath. Process until the sugar becomes moist and pale yellow, which releases the essential oils from the zest for maximum flavor.
- Cream the butter and sugar:
- Beat the softened butter and lemon sugar together for a full three minutes in your stand mixer. This extended creaming creates air pockets that help the cake rise properly and develop a tender crumb. Be sure to scrape down the sides of the bowl several times during this process.
- Add eggs and flavorings:
- Incorporate eggs one at a time, allowing each to fully integrate before adding the next. This prevents the batter from curdling and ensures proper emulsion. Add the lemon paste if using, which amplifies the citrus flavor throughout the cake.
- Combine remaining ingredients:
- Reduce mixer speed to low and gently fold in the flour mixture just until barely combined. Overmixing at this stage develops gluten which toughens cake. Follow immediately with buttermilk and fresh lemon juice, mixing until everything comes together into a smooth batter.
- Bake with care:
- Divide batter evenly between prepared pans, spreading to create level layers. Bake just until a toothpick inserted in the center comes out clean without wet batter, approximately 23 to 25 minutes. These thin layers cook quickly so watch carefully to avoid overbaking which would dry out your cake.
- Cool completely:
- Allow cakes to cool in pans placed on cooling racks. Once completely cooled, carefully flip each layer and remove the parchment paper. Proper cooling prevents the layers from breaking and allows the structure to set.
- Prepare frosting:
- Cream butter and confectioners sugar together, gradually adding fresh lemon juice until reaching a spreadable consistency. Incorporate poppy seeds throughout the frosting. Adjust thickness by adding more juice to thin or sugar to thicken as needed. Optional food coloring creates a pale yellow tint.
- Assemble and decorate:
- Stack cooled cake layers with frosting between each. Cover entire cake with remaining frosting, then garnish with thin lemon slices and fresh mint leaves for a professional presentation.

The fresh lemon zest is truly the star ingredient in this recipe. I discovered the technique of processing it with sugar years ago from a pastry chef friend, and it revolutionized my citrus baking. The essential oils infuse the sugar completely, distributing bright flavor throughout every bite instead of just getting occasional bursts of lemon.
Storage Tips
This cake keeps beautifully at room temperature for two days when stored in an airtight container. The buttermilk and lemon juice in the batter help maintain moisture even after several days. For longer storage, refrigerate for up to a week, though allow slices to come to room temperature before serving for the best flavor and texture. The entire cake can also be frozen before or after frosting for up to three months.
Seasonal Variations
In summer, consider adding fresh berries between the layers or as a decorative topping. Raspberries and blueberries pair particularly well with the lemon flavor. During winter holidays, crystallized ginger makes a sophisticated addition to the batter. Spring celebrations call for edible flowers as garnish, while fall gatherings might benefit from a light dusting of cinnamon in the frosting for warmth.
Serving Suggestions
Serve thin slices of this rich cake alongside fresh berries and a dollop of whipped cream for an elegant dessert. For afternoon tea, pair with Earl Grey or chamomile tea to complement the citrus notes. The cake also makes a beautiful centerpiece for baby showers, bridal celebrations, or Easter gatherings when decorated with seasonal touches.

Frequently Asked Questions
- → Can I use all-purpose flour instead of cake flour?
Yes, you can substitute all-purpose flour for cake flour as mentioned in the ingredients list. The cake will still turn out delicious, though it may have a slightly denser texture compared to using cake flour.
- → What is lemon paste and is it necessary?
Lemon paste is a concentrated flavoring that adds intense lemon flavor without additional liquid. While marked as optional in the recipe, it enhances the citrus profile. You can omit it and still achieve excellent results with just the fresh lemon juice and zest.
- → How do I prevent my cake layers from sticking to the pans?
This cake is prone to sticking, so follow the three-step process for best results: grease the pans, dust them with flour, and line the bottoms with parchment paper rounds. The parchment paper is particularly important for easy removal.
- → Can I make this cake in advance?
Yes, you can bake the layers 1-2 days ahead and store them well-wrapped at room temperature. The assembled frosted cake will stay fresh in the refrigerator for up to 3 days. Bring to room temperature before serving for the best flavor and texture.
- → How do I get the best lemon zest for this cake?
Use a serrated vegetable peeler to remove just the yellow part of the lemon skin, avoiding the bitter white pith. Processing this zest with sugar creates a fragrant lemon sugar that distributes the oils throughout the batter for maximum flavor.
- → Can I freeze this cake?
Yes, you can freeze the unfrosted cake layers wrapped tightly in plastic wrap for up to 1 month. The fully frosted cake can also be frozen, though the texture of the frosting may change slightly upon thawing. Defrost overnight in the refrigerator before serving.
