Step 1: Bake the Cake

– Prepare the cake mix according to package instructions

– Pour into a greased 9×13 pan

– Bake until a toothpick inserted in the center comes out clean

– Let the cake cool for about 15–20 minutes

Step 2: Poke the Holes

– Use the handle of a wooden spoon or a straw

– Poke holes evenly across the cake, spacing them about 1 inch apart

– Go deep, but don’t poke all the way through the bottom

Step 3: Prepare the Filling

– Dissolve each gelatin flavor separately in hot water

– Add cold water (slightly less than directed)

– Stir until fully dissolved

Step 4: Fill the Cake

– Carefully pour red gelatin into half the holes

– Pour green gelatin into the remaining holes

– Pour slowly to prevent colors from mixing

Step 5: Chill

– Refrigerate the cake for at least 2–3 hours

– This allows the filling to fully set

Step 6: Frost and Decorate

– Spread whipped topping evenly over the chilled cake

– Add festive decorations just before serving
