Prep pans. Preheat the oven to 350°F. Line three 8-inch round cake pans with parchment circles, spray with nonstick cooking spray, and set aside.
Mix dry. In a very large bowl, whisk together the cake mix, all-purpose flour, granulated sugar, salt, instant pudding mix, and cinnamon if using.
Mix wet. In a separate bowl, whisk together the eggs, sour cream, vegetable oil, milk, and vanilla extract.
Combine. Add the wet ingredients to the dry ingredients and mix until smooth and no flour streaks remain.
Bake. Divide the batter evenly between prepared pans and smooth the tops. Bake for 25 to 30 minutes, until a toothpick inserted in the center comes out clean.
Cool and soak. Let cakes cool in pans for 10 minutes. Turn out onto wire racks while warm, poke the tops with a toothpick, and spoon tres leches syrup over each layer.
Make syrup. Whisk together the evaporated milk, sweetened condensed milk, heavy whipping cream, and vanilla extract. Reserve 1 cup for the frosting. Spoon remaining syrup over the cakes in stages, allowing it to absorb fully.
Make frosting. Whisk the instant pudding mix with the reserved syrup and let sit briefly to thicken. In a separate bowl, beat the heavy whipping cream with vanilla extract until stiff peaks form. Gently beat in the pudding mixture just until incorporated.
Assemble. Frost the tops of two cake layers, add sliced strawberries, and spread a thin layer of frosting over the fruit. Stack layers and chill the cake for 30 minutes to set.
Finish. Frost the outside of the cake as desired and garnish with fresh strawberries. Slice and serve.
Notes
Level layers. Trim cake tops if needed for even stacking.
Soaking method. Add syrup gradually and allow absorption to prevent instability.
Frosting control. Chill frosting or cake for 10 to 15 minutes if it becomes too soft to work with.
Decorating tip. Lightly dust cinnamon along the sides to hide imperfections.
Storage. Keep refrigerated due to dairy content and serve chilled or slightly cool.
