Preheat your oven to 350°F. While it heats, grease a 9x13 inch baking dish thoroughly with butter or cooking spray to prevent sticking. This advance preparation ensures your oven reaches the correct temperature and your pan is ready the moment you're finished assembling the cake.

Hull and slice your fresh strawberries into 1/2-inch thick pieces, then toss them with the lemon juice to brighten their flavor and prevent browning. Pour the canned strawberry pie filling into your prepared baking dish, then gently fold in the fresh strawberries. This combination of fresh and canned fruit gives you the best of both worlds—the rich syrup from the filling plus the fresh texture and flavor of real berries.

Sprinkle the dry cake mix evenly over the strawberry filling layer—don't stir or mix it in, as the dry mix will create a wonderful cake texture as it bakes and absorbs the fruit juices. In a small bowl, whisk the vanilla extract into the melted butter, then pour it evenly over the top of the cake mix. I like to use quality butter like Kerrygold because it adds a richer, more flavorful result that really shines in this simple dessert. The butter will help the cake mix cook into a golden crust while keeping the interior moist.

Place the baking dish in your preheated 350°F oven and bake for 35-45 minutes, until the top is golden brown and a toothpick inserted into the cake portion comes out clean or with just a few moist crumbs. The cake should pull slightly away from the edges of the pan when done. The baking time can vary depending on your oven, so start checking at 35 minutes.

Remove the baking dish from the oven and let it cool for 10-15 minutes before serving. This resting time allows the cake to set up slightly while still remaining warm and delicious. Scoop into bowls and top with a generous dollop of whipped cream or a scoop of vanilla ice cream—the cold topping against the warm cake creates the perfect contrast.
