Step 1: Preheat and Prepare Your Pan Preheat your oven to 375°F (190°C). Grease a 7-inch springform pan with cooking spray and line the bottom and sides with parchment paper to help the cake come out easily after baking.
Step 2: Combine the Dry Ingredients Whisk together flour, sugar, baking powder, and salt in a large bowl to evenly distribute the dry ingredients.
Step 3: Mix the Wet Ingredients In a separate bowl, beat the eggs and vegetable oil until smooth. Add lemon juice, lemon zest, and vanilla extract, and mix until well combined.
Step 4: Combine Wet and Dry Ingredients Pour the wet mixture into the dry ingredients and gently mix until fully combined. Avoid overmixing to prevent a dense cake.
Step 5: Add the Poppy Seeds Fold in the poppy seeds for flavor and texture.
Step 6: Bake the Cake Pour the batter into the prepared pan, smoothing it out evenly. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
Step 7: Add the Topping While the cake bakes, prepare the topping by heating milk, butter, and sugar in a saucepan until the butter melts and sugar dissolves. Once the cake is out of the oven, poke holes all over it using a skewer or toothpick, then pour the warm milk mixture evenly over the cake to soak it in.
Step 8: Make the Glaze Mix confectioners' sugar and milk to create a smooth glaze. Once the cake has cooled slightly (10-15 minutes), drizzle the glaze over the top, allowing it to settle into the holes before serving.
