A festive and creamy mint-flavored poke cake inspired by the classic Shamrock Shake, perfect for St. Patrick’s Day celebrations. This easy homemade dessert combines moist white cake, minty vanilla pudding, and whipped topping for a luscious treat.

Ingredients

Scale
  • 1 box white cake mix (about 15.25 oz / 432 g) – Betty Crocker recommended
  • Ingredients called for on cake mix box (usually eggs, oil, and water)
  • Green food coloring (optional)
  • 1 package (3.4 oz / 96 g) instant vanilla pudding mix
  • 2 cups (16 fl oz / 480 ml) cold whole milk
  • 1 teaspoon peppermint extract
  • Green food coloring (to deepen color)
  • 1 tub (8 oz / 227 g) whipped topping, thawed (Cool Whip or dairy-free alternative)
  • Optional: green sprinkles or crushed peppermint candies for garnish

Instructions

  1. Preheat oven to 350°F (175°C). Lightly grease a 9×13 inch baking pan with butter or non-stick spray.
  2. Prepare the cake batter by mixing the white cake mix with eggs, oil, and water according to box instructions. Add green food coloring if desired.
  3. Pour batter evenly into the prepared pan and smooth the top with a spatula.
  4. Bake for 30-35 minutes. Insert a toothpick at 30 minutes; it should come out mostly clean with a few moist crumbs.
  5. Let the cake cool for 10 minutes. Using a skewer or wooden spoon handle, poke holes about 1 inch apart all over the cake.
  6. In a medium bowl, whisk instant vanilla pudding mix and cold milk for about 2 minutes until thickened. Stir in peppermint extract and green food coloring.
  7. Pour pudding evenly over the warm cake, allowing it to seep into the holes. Spread gently with a spatula if needed.
  8. Refrigerate the cake for at least 1 hour to set the pudding and meld flavors.
  9. Before serving, spread a thick layer of whipped topping over the chilled cake. Smooth with a spatula and sprinkle with green sprinkles or crushed peppermint candies if desired.
  10. Slice, serve chilled, and enjoy. Keep leftovers refrigerated.

Notes

Use room temperature ingredients for best results. Be gentle when poking holes to avoid crumbling. Chill the cake with pudding before adding whipped topping to prevent melting. For extra creaminess, add a splash of heavy cream to pudding. Variations include chocolate mint, vegan, adult twist with Irish cream, and allergen-friendly options.
