Step 1: Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking pan.
Step 2: Prepare the white cake mix according to the package directions. Pour the batter into the prepared pan and bake as directed until a toothpick comes out clean.
Step 3: Allow the cake to cool for about 10-15 minutes. While still warm, use the handle of a wooden spoon to poke holes across the entire surface of the cake, spaced about 1 inch apart.
Step 4: In two separate small bowls, dissolve each flavor of gelatin in 1 cup of boiling water. Once dissolved, stir 1/2 cup of cold water into each bowl.
Step 5: Carefully pour or spoon the gelatin liquids into the holes of the cake, alternating colors to create a pastel marble effect.
Step 6: Cover the cake with plastic wrap and refrigerate for at least 4 hours, or overnight, to allow the gelatin to set and the cake to moisten.
Step 7: Once chilled, spread the thawed whipped topping evenly over the top of the cake.
Step 8: Garnish with pastel sprinkles or festive Easter candies just before serving. Slice and enjoy your easter poke cake recipe!
