Ingredients Needed
- Cake mix + prep
- 1 (15-ounce) box vanilla or white cake mix (plus eggs, oil, and water called for on the box)
- Raspberry Jello syrup
- 1 (3-ounce) box raspberry Jello
- 1 cup hot water
- 3/4 cup cold water
- Topping & garnish

- Mint leaves for garnish
Step-by-Step Instructions
- Preheat oven and prepare the cake mix according to the box directions; pour batter into a greased 9×13-inch pan.
- Bake the cake as directed on the box until a toothpick comes out clean; allow the cake to cool for about 10 minutes.

Tips for Success Jello Poke Cake
- Let the cake cool slightly before poking so it holds structure but still absorbs the Jello.
- Pour the Jello while it’s warm for better absorption into the holes.
- Chill at least 2 hours, but overnight yields the best texture and flavor.
- Use full thawed Cool Whip for a smooth topping; for a fruity twist, see the tips on the strawberry poke cake page.
- Store covered in the fridge to keep it from drying and to maintain creaminess.
Variations
Here are a few easy ways to change it up:
- Swap flavors: try lemon, lime, or strawberry Jello to match seasonal fruit.
- Dairy-free option: use coconut whipped topping and check the cake mix for dairy-free labeling.
- Layered version: make two smaller pans with different Jello flavors and stack for a striped effect.
