Creating the Red, White, and Blue Poke Cake is a fun and straightforward process. Follow these steps to make your incredible dessert:

1. Prepare Your Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan.
2. Make the Cake Batter: In a large bowl, combine the cake mix, eggs, and water. Mix well until you have a smooth batter.
3. Bake the Cake: Pour the batter into the prepared pan and spread evenly. Bake according to the package instructions or approximately 25-30 minutes, until a toothpick inserted in the center comes out clean.
4. Cool the Cake: Remove it from the oven and let it cool in the pan for about 10 minutes. Then, transfer it to a wire rack to cool completely.
5. Poke Holes: Once cooled, use the back of a wooden spoon or a straw to poke holes all over the top of the cake. Ensure they are evenly spaced.
6. Prepare the Filling: In a medium bowl, mix together the sweetened condensed milk, heavy cream, and vanilla extract until smooth.
7. Add Food Coloring: Divide the mixture into two bowls. Add a few drops of red food coloring to one bowl and blue to the other, mixing until you achieve the desired color.
8. Fill the Holes: Pour the red mixture over one half of the holes in the cake and the blue mixture over the other half. Allow the cake to sit for about 30 minutes, letting the filling soak in.
9. Top with Whipped Cream: Spread whipped cream over the entire top of the cake, covering it generously.
10. Decorate with Berries: Place fresh strawberries and blueberries decoratively on top of the whipped cream.
11. Chill: For the best taste, refrigerate the cake for at least 1 hour before serving to allow the flavors to meld.

By following these steps, you will create a stunning and flavorful Red, White, and Blue Poke Cake that will have everyone begging for seconds!
