Ingredients

1 box (15.25 oz) yellow cake mix
1 cup water (for cake batter)
1/3 cup vegetable oil
3 large eggs
1 cup fruit-flavored gelatin (such as strawberry, raspberry, or cherry)
1 1/2 cups boiling water (for gelatin)
1 cup cold milk
1 package (8 oz) cream cheese, softened
1/2 cup granulated sugar
1 teaspoon vanilla extract
1 1/2 cups heavy whipping cream
Fresh fruit or sprinkles for garnish (optional)

Instructions

Preheat your oven to 350°F (175°C). Grease a 12×18-inch baking dish with butter or non-stick spray to prevent sticking.

Prepare the cake batter: In a large mixing bowl, combine the cake mix, water, vegetable oil, and eggs. Mix on low speed for 30 seconds, then increase to medium and beat for 2 minutes until smooth.
Bake the cake: Pour the batter into the prepared baking dish, spreading evenly. Bake for 20-25 minutes or until a toothpick inserted into the center comes out clean. Allow the cake to cool completely in the dish on a wire rack.
Make the gelatin: In a heatproof bowl, dissolve the gelatin in boiling water, stirring until fully dissolved. Let it cool slightly, then pour evenly over the cooled cake. Use a skewer or fork to gently poke holes all over the cake, allowing the gelatin to seep in. Refrigerate for at least 2 hours or until the gelatin is set.

Prepare the cream layer: In a mixing bowl, beat the softened cream cheese, sugar, and vanilla until smooth. In a separate bowl, whip the heavy cream until stiff peaks form. Gently fold the whipped cream into the cream cheese mixture until combined.
Assemble the cake: Spread the cream mixture evenly over the set gelatin layer. Return the cake to the fridge and chill for another 2 hours or until the topping is firm.
Serve: Slice the cake into squares or rectangles and garnish with fresh fruit or sprinkles if desired. Serve chilled for the best flavor and texture.

Tips

Substitutions: You can swap the fruit-flavored gelatin for other flavors like lemon or lime for a different twist. Use coconut milk or almond milk in place of regular milk for dairy-free options.
Storage: Keep leftovers refrigerated in an airtight container for up to 3 days. The cake tends to become even more flavorful as it sits, thanks to the gelatin infusion.
Common mistakes: Avoid pouring hot gelatin directly over the cake; let it cool slightly to prevent melting the cake or creating a soggy bottom. Also, ensure the cake is fully cooled before adding gelatin to prevent melting or uneven setting.

Additional tips: For a more vibrant look, use brightly colored gelatin and garnish with matching fruit or sprinkles. To enhance flavor, add a splash of liqueur or citrus zest to the cream topping.

Serving Suggestions

This poke cake pairs wonderfully with a dollop of whipped cream or a scoop of vanilla ice cream. Serve it chilled during warm weather or at parties where its colorful layers can be on display. For a more indulgent touch, drizzle with chocolate or caramel sauce just before serving.

Variations

Experiment with different flavors by changing the gelatin and toppings. For example, use lemon gelatin with blueberries and lemon zest for a refreshing summer version. You can also layer different flavors of gelatin for a rainbow effect. Incorporate chopped nuts or crushed cookies into the cream topping for added texture. For a tropical twist, add shredded coconut or pineapple chunks to the cream layer.

Storage and Reheating

Store the poke cake in an airtight container in the refrigerator for up to 3 days. Because of the gelatin and cream layers, it’s best to keep it chilled to maintain its structure and freshness. If you want to serve it again after a day or two, simply remove it from the fridge about 15 minutes before serving to allow it to soften slightly. Do not freeze the cake, as the texture of the gelatin and cream layers may become compromised upon thawing.

Frequently Asked Questions

Can I make this cake ahead of time?

Yes, this poke cake can be made a day in advance. Prepare the layers and refrigerate each step as indicated. It’s best to assemble the final layers on the day of serving to keep the topping fresh, but overall, it holds well overnight.

Can I use homemade cake instead of a box mix?

Absolutely. If you prefer homemade cake, use your favorite recipe for a 12×18-inch sheet cake. Just make sure it’s cooled thoroughly before adding gelatin to prevent melting or sogginess.

Is this cake suitable for people with nut allergies?

This recipe as written does not contain nuts, but always double-check ingredient labels, especially for cake mix and gelatin, to ensure they are nut-free. Be cautious with garnishes like sprinkles or toppings that might contain nuts.

Can I freeze leftovers?

It’s not recommended to freeze this cake because the gelatin and cream layers may lose their texture upon thawing. It’s best enjoyed fresh or stored in the refrigerator for up to 3 days.

What other toppings work well with this poke cake?

Fresh berries, sliced fruit, whipped cream, or a drizzle of chocolate or caramel sauce are excellent toppings. Sprinkles, toasted coconut, or chopped nuts can add extra flavor and visual appeal.

How can I make this cake dairy-free?

Use dairy-free cream cheese, coconut milk, and dairy-free whipped topping alternatives. Choose a gelatin that is plant-based if you prefer vegetarian or vegan options.
