Bake cake according to package directions. You can use any Strawberry cake mix - Duncan Hines, Pillsbury and Betty Crocker all have Strawberry Cake Mixes.
Once cake is fully cooked, let stand on counter 10 minutes to slightly cool down before next steps.
Time to make the holes! Use a wooden handle spoon to poke little holes into the warm cake. A wooden spoon handle tends to work the best and is the perfect size.
Pour sweetened condensed milk onto top layer of cake, focusing on filling the holes with the sweet milk.
The milk should soak into the cake.
Let stand until cake is room temperature before going on to next step.
Pour thawed strawberries over cake, including any strawberry juice from bag.
Top poke cake with whipped topping and serve. For presentation is more attractive to use a piping bag and frosting tip to make little stars on the cake, however, you can also do dollops with a spoon or use a can of spray whipped cream for ease.
Keep cake refrigerated and covered if not serving.
