When I lived abroad I often missed family celebrations, especially birthdays. To make up for being away I would bake cakes inspired by loved ones, share the recipes, and eat the results while thinking of home. One year I made this cake for my mum. It features all of her favorite things: lemon, poppy seeds, and a harmony of bright tartness and balanced sweetness.

I first shared this recipe years ago and recently refreshed it with updated photos and clearer instructions. The result is the same reliably delicious cake, now easier to follow.

How to make this lemon poppy seed cake

Shortcut option: If you’re short on time, use store-bought lemon curd and store-bought frosting. For this recipe plan on about 2.5 lb of frosting and one 10 oz jar of lemon curd.

Make the lemon curd: Whisk sugar, lemon juice, lemon zest, and egg yolks in a heatproof bowl set over simmering water. Cook, stirring frequently, until the mixture thickens to a pudding-like consistency. Remove from heat and cool for 10 minutes, then whisk in cubed butter until smooth. Cover and chill completely before using.

Make the cake: Combine the milk and butter in a heatproof bowl and warm in short bursts until the butter melts and the mixture is smooth. In a stand mixer bowl, beat eggs and sugar until pale and airy. Add dry ingredients and mix on low until just combined, then incorporate the remaining wet ingredients. Fold in poppy seeds and lemon zest. Divide the batter evenly into three 6″ parchment-lined and greased cake pans. Bake at 350°F (175°C) for about 22–25 minutes, or until a toothpick inserted in the center comes out clean. Cool completely before assembling.

Prepare the vanilla buttercream: Make a stabilized Swiss-style buttercream by boiling water and granulated sugar into a clear syrup. Whip egg whites to stiff peaks, then pour the hot syrup into the whites while whipping on high. Continue whipping until the mixture cools to room temperature. With the mixer on low, add cold cubed butter a little at a time, then add vanilla and increase speed to achieve a thick, silky buttercream.

Assemble the cake: Level the cake layers if needed. Spread frosting between layers, carving a shallow well in the frosting on each layer to hold lemon curd, then add a layer of curd. Stack the layers, apply a thin crumb coat, and chill until set. Finish with a final coat of buttercream and smooth with an offset spatula or bench scraper. Tint a portion of the frosting pale yellow and apply to the lower half of the cake for a subtle ombre effect.

For the drip, melt yellow candy melts with heavy cream in short bursts until smooth, then transfer to a piping bag and apply drips around the edge. Pipe a crown of frosting on top using a large star tip and finish with a few decorative accents if desired.

Expert tips

  • Make lemon curd ahead: Lemon curd keeps well in the refrigerator for up to a week, which can save time when assembling the cake.
  • Weigh or measure batter for even layers: Aim for roughly 9.3 oz of batter per 6″ pan to achieve uniform layers across three pans.
  • Chill layers before decorating: Chilled cakes are easier to trim and handle, and they help the crumb coat set more cleanly.
  • Store-bought frosting: Substitute about 2.5 lb of store-bought frosting if you prefer a quicker option.
  • Crumb coat: A thin crumb coat followed by refrigeration traps loose crumbs and yields a smooth final finish.
  • Smoothing tip: Use a rotating cake stand and a bench scraper. Remove excess frosting, warm the scraper in hot water, wipe it dry, and glide around the cake for a polished edge.
  • Storage: An uncut cake can sit at room temperature for 3–4 days when covered. After slicing, wrap exposed portions to prevent drying.

  • Category: Dessert
  • Cuisine: American

Ingredients

For the lemon curd:

  • ½ cup granulated sugar
  • ¼ cup lemon juice (about half a large lemon)
  • 1 tbsp lemon zest
  • 4 egg yolks
  • ¼ cup unsalted butter

For the lemon poppy seed cake:

  • ½ cup whole milk
  • ½ cup unsalted butter
  • 3 eggs
  • 1 ½ cups granulated sugar
  • 3 tbsp lemon juice (about half a large lemon)
  • 1 tbsp lemon zest
  • 1 tsp poppy seeds
  • 2 tsp baking powder
  • 1 ½ cups all-purpose flour

For the vanilla buttercream:

  • 10 egg whites
  • 2 ¼ cups granulated sugar
  • 10 tbsp water
  • 1.25 lb unsalted butter, cold
  • 1 tsp vanilla extract
  • Yellow food coloring (optional)

For the ganache drip:

  • 4 oz yellow candy melts
  • 3 tbsp heavy whipping cream

Instructions

  1. For the lemon curd: whisk sugar, lemon juice, zest, and egg yolks in a heatproof bowl set over simmering water.
  2. Cook until the mixture thickens to an almost pudding-like consistency, stirring occasionally.
  3. Remove from heat and cool for about 10 minutes, then whisk in cubed butter until smooth. Chill completely before using.
  4. Combine milk and butter for the cake and warm until smooth. In a mixer, beat eggs and sugar until light and fluffy, add dry ingredients and mix on low until just combined, then finish with remaining wet ingredients.
  5. Divide batter into three prepared 6″ pans and bake at 350°F for 22–25 minutes or until a toothpick comes out clean. Cool completely.
  6. For the buttercream: boil sugar and water to a clear syrup. Whip egg whites to stiff peaks, then stream in the hot syrup while whipping. Whip until cooled, then add cold butter and vanilla on low, beating to a smooth buttercream.
  7. Level cakes, spread frosting between layers and carve a small well to hold lemon curd. Stack layers and apply a crumb coat, chilling until set.
  8. Finish with a smooth final coat. Tint a portion of frosting pale yellow and apply to the lower half for color. Melt candy melts with cream and apply drip, then pipe a frosting crown on top.

Notes

  • Make ahead: Lemon curd keeps in the refrigerator for up to a week.
  • Even layers: Measure batter for consistent layer heights — about 9.3 oz per 6″ pan.
  • Chill before decorating: Chilled layers are easier to trim and frost.
  • Store-bought substitutions: Use 2.5 lb of store-bought frosting if desired.
  • Crumb coat: A thin crumb coat sealed in the fridge prevents crumbs in the final finish.
  • Smooth finish tip: Use a rotating stand and bench scraper; warm and wipe the scraper for a polished edge.
  • Storage: Uncut, the cake keeps at room temperature for 3–4 days when covered. Wrap slices to protect exposed surfaces after cutting.
