- 2½ teaspoon baking powder
- ½ teaspoon salt
- ¾ cup (170 g) unsalted butter, room temperature

Step-by-step instructions
Prepare your pans
Preheat oven to 350°F (180°C). Grease and line two 8-inch cake pans with parchment paper.
Mix the dry ingredients
Sift together flour, cornstarch, baking powder, and salt. Whisk until well combined, then set aside.
Make the batter
In a large bowl, beat butter, oil, sugar, and lemon zest on medium speed for 2 minutes until light and creamy.
Add the eggs one at a time, mixing well between each. Scrape down the sides of the bowl so everything blends evenly.
Mix in the milk, yogurt, and lemon juice. Don't worry if the mixture looks a bit curdled - that's normal.
Set the mixer aside and gently fold in the dry ingredients with a spatula. Stir in the poppy seeds, being careful not to overmix.
Bake the cake
Divide the batter evenly between your pans. Bake for about 33 minutes, or until a toothpick comes out clean or with a few moist crumbs.
Let the cakes cool in the pans for 15-20 minutes before transferring to a wire rack to cool completely.
Make the cream cheese frosting
In a large bowl, beat the butter until light and fluffy.
Add powdered sugar in three batches, mixing on low speed until fully combined.
Add the cream cheese, vanilla, and lemon juice. Mix just until smooth (don't overbeat or the frosting can turn runny).
Assemble and decorate
Level the cake layers if needed. Place one layer on a cake stand and spread a generous amount of frosting on top.
Set the second cake layer on top, then frost the top and sides. Use a cake scraper for smooth edges.
Pipe swirls of frosting around the top if you'd like, then sprinkle extra poppy seeds over for a pretty finish.
Slice, serve, and enjoy!
Storage tips
- Keep at room temperature (covered) for 2-3 days
- Refrigerate up to 5 days - bring to room temp before serving
- Freeze unfrosted layers (wrapped in plastic and foil) for up to 3 months
Recipe variations
- Gluten-free: use a 1:1 gluten-free baking flour with xanthan gum
- Citrus twist: add orange or lime zest for a fun variation
- Lighter version: swap Greek yogurt for sour cream if you prefer a tangier cake
Expert tips
- Measure flour by weight for best results
- Always use fresh lemon juice, bottled just doesn't taste the same
- Toss poppy seeds lightly in flour before mixing into the batter to prevent sinking
- Let the cake cool completely before frosting to avoid melting
