Ready to make a dessert that becomes an instant favorite? This Lemon Poke Cake is simple to prepare, deliciously moist, and full of fresh lemon flavor.
Using freshly squeezed lemon juice and lemon zest is the key to a bright, authentic citrus flavor. The cake batter stays tender thanks to a mix of butter and vegetable oil, while the poke-and-fill step ensures every slice is soaked with creamy, tangy filling.

Key to Success #1 – Start with a Moist, Tender Lemon Cake
Begin by creaming softened butter and sugar until the mixture is light and fluffy. Add vegetable oil, lemon zest and vanilla, then beat in eggs and freshly squeezed lemon juice. Sift together the flour, baking powder, baking soda, and salt, and incorporate them into the wet ingredients, alternating with milk. Mix just until combined to avoid a dense cake.
Pour the batter into a greased 9×13-inch pan and bake at 350°F for 30–40 minutes, or until a toothpick inserted in the center comes out clean. Let the cake rest briefly before moving to the next step.

Key to Success #2 – Poke Holes All Over the Cake
Once the cake is out of the oven, use a skewer or the rounded end of a wooden spoon to poke holes about an inch apart across the surface, pressing roughly two-thirds of the way into the cake. These holes let the filling sink deep into the crumb so each bite is tender and flavorful.
Mix sweetened condensed milk with freshly squeezed lemon juice and pour the mixture slowly over the hot cake, trying to guide the liquid into each hole. Allow the cake to cool at room temperature so the filling has time to absorb fully.

Key to Success #3 – Make a Silky Mascarpone Whipped Topping
A mascarpone-infused whipped cream makes the perfect topping for this cake. Whip heavy cream and powdered sugar to stiff peaks, then fold in room-temperature mascarpone cheese, lemon juice, and vanilla until the mixture is smooth and creamy. Keeping the mascarpone at room temperature prevents lumps and helps it blend seamlessly with the whipped cream.
The mascarpone adds a rich, buttery note that balances the lemon’s brightness, resulting in a velvety topping that enhances the cake without overpowering it. Spread or pipe the topping over the cooled, filled cake just before serving.
