Ingredients You’ll Need

• 2 cups + 2 tablespoons all-purpose flour: The base of the cake, gives structure and a tender crumb. Use a kitchen scale for accuracy.
• 1 tablespoon baking powder: This leavening agent ensures the cake rises beautifully.
• ½ teaspoon fine sea salt: Enhances the flavor and balances the sweetness.
• ¾ cup unsalted butter, softened: Adds a rich, buttery flavor and moisture. Ensure it’s at room temperature for easy creaming.
• 1 ¾ cup granulated sugar: Sweetens the cake and helps keep it moist. You can replace it with a sugar alternative if needed.
• 3 large eggs: Binds the ingredients together and adds richness. Use eggs at room temperature for the best texture.
• 1 cup whole milk, room temperature: Contributes moisture; if you’re lactose intolerant, nut milk can be a good substitute.
• ¼ cup fresh squeezed lemon juice: For that zesty punch—fresh is best! Bottled juice won’t have the same bright flavor.
• Zest of 2 lemons: Adds intense lemon flavor! Be careful to zest only the yellow part, avoiding the bitter white pith.
• 1 tablespoon vanilla extract: Rounds out the flavors. Use pure vanilla for the best results.
• ¼ cup poppy seeds: Adds a lovely texture and a nutty flavor; make sure to check for freshness.
• ½ cup unsalted butter, softened (for frosting): This creates a rich, creamy buttercream frosting.
• 2 cups powdered sugar: Sweetens the frosting and contributes to a smooth texture.
• Pinch of sea salt: Balances the sweetness of the frosting.
• 1 tablespoon fresh squeezed lemon juice (for frosting): Adds brightness to the frosting.
• Zest of 1 lemon (for frosting): Enhances the lemon flavor in the frosting.
• 1 teaspoon vanilla extract (for frosting): For that extra layer of flavor.

How to Make Lemon Poppy Seed Cake

1. Preheat the oven: To 350 degrees F, and prepare a 9×13-inch baking pan with non-stick baking spray.
2. Mix dry ingredients: In a medium bowl, whisk together 2 cups + 2 tablespoons of all-purpose flour, 1 tablespoon of baking powder, and ½ teaspoon of fine sea salt. Set this mixture aside.
3. Cream butter and sugar: In the bowl of a stand mixer with a paddle attachment, beat ¾ cup of softened unsalted butter with 1 ¾ cup of granulated sugar until light and fluffy, about 2 minutes. Be sure to scrape down the sides of the bowl to incorporate all ingredients.
4. Add eggs: Beat in 3 large eggs one at a time, mixing well after each addition for a smooth batter.
5. Combine dry and wet ingredients: Gently add the flour mixture to the butter-sugar mixture and stir until just combined, scraping down the sides of the bowl as needed.
6. Stir in wet ingredients: Add 1 cup of room temperature whole milk, ¼ cup of fresh lemon juice, the zest of 2 lemons, and 1 tablespoon of vanilla extract. Stir until combined.
7. Add poppy seeds: Fold in ¼ cup of poppy seeds gently, ensuring they are evenly distributed without over-mixing the batter.
8. Bake the cake: Pour the batter into the prepared baking dish, smoothing it out evenly. Bake for 35-42 minutes, or until a toothpick inserted in the center comes out clean. The edges should be lightly golden.
9. Cool the cake: Once baked, remove the pan from the oven and let it cool on a wire rack completely.
10. Make the frosting: In a large bowl using an electric hand mixer, beat ½ cup of softened unsalted butter until smooth, about 1 minute. Gradually add 2 cups of powdered sugar until fully incorporated.
11. Add flavorings: Mix in 1 tablespoon of fresh lemon juice, the zest of 1 lemon, and 1 teaspoon of vanilla extract until fully combined.
12. Beat the frosting: On medium speed, beat the frosting until it’s light and fluffy, about 3 minutes.
13. Frost the cake: Once the cake is completely cooled, generously spread the lemon buttercream frosting over the top. Slice, serve, and enjoy!

Storing & Reheating

To keep your Lemon Poppy Seed Cake fresh, store it at room temperature in an airtight container for up to 2 days, or refrigerate for up to a week. For longer storage, you can freeze the cake for up to 3 months. Wrap individual slices in plastic wrap and place them in a freezer-safe bag. When ready to enjoy, thaw the slices in the refrigerator or at room temperature. To refresh the flavor, a quick 10-second pop in the microwave can help restore its deliciousness, but keep an eye on it to maintain the cake’s moistness.

Chef’s Helpful Tips

• Avoid overmixing: Stir only until the ingredients are combined, as overmixing can lead to a dense cake.
• Use room temperature ingredients: This ensures everything blends smoothly, giving your cake a light texture.
• Check the freshness of your baking powder: Old powder may not provide adequate leavening, affecting your cake’s rise.
• Experiment with flavors: Adding a touch of almond extract can elevate the cake’s flavor profile.
• Consider make-ahead options: The cake can be made a day in advance, and the flavors will enhance overnight.
