Preheat your oven to 375°F (190°C). In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt until well combined.

In a separate large bowl, using an electric mixer, beat the large eggs and granulated sugar on medium-high speed until the mixture is pale, thick, and fluffy, about 3-5 minutes.

Add the vanilla bean paste, vegetable oil, melted unsalted butter, and milk to the egg mixture. Mix on low speed until just smooth and combined.

Gradually add the dry ingredients to the wet ingredients, mixing on low speed just until combined. Be careful not to overmix.

Gently fold in the roughly crushed Oreo cookies into the cake batter.

Pour the batter into a greased 9x13-inch baking dish. Bake in the preheated oven for 25–30 minutes, or until a toothpick inserted into the center of the cake comes out clean.

Remove the cake from the oven and let it cool in the baking dish for 15–20 minutes. While still warm, use a fork or skewer to poke holes all over the surface of the cake.

While the cake is cooling, prepare the Tres Leches mixture. In a medium bowl, whisk together the evaporated milk, sweetened condensed milk, milk, and vanilla extract until thoroughly combined.

Slowly and evenly pour the Tres Leches mixture over the entire surface of the poked cake, ensuring it soaks into all the holes.

Cover the baking dish with plastic wrap and refrigerate for at least 4 hours, or preferably overnight, to allow the cake to fully absorb the milk mixture and chill completely.

Once the cake is thoroughly chilled, prepare the whipped topping. In a large bowl, using an electric mixer, whip the heavy whipping cream with the powdered sugar and vanilla extract until stiff peaks form.

Spread the whipped topping evenly over the chilled cake. Garnish with additional crushed Oreo cookies and mini Oreo cookies, if desired, before serving.
