- Vanilla cake mix (15.25 oz): The base that bakes up light and fluffy, providing the perfect foundation.
- Large eggs (3): Bind everything together and add richness to the batter.
- Water (1 cup): Moisturizes the cake ensuring a tender crumb.
- Sweetened condensed milk (14 oz can): Pours over the cake to infuse it with creamy sweetness.
- Chocolate syrup (1 cup): Adds a luscious, chocolatey layer that sinks into every hole.
- Heath Bar bits (1 cup): The star—giving crunch and a buttery toffee flavor.

- Milk chocolate shavings (¼ cup): A pretty garnish that adds extra chocolate punch and visual appeal.
How to Make Heath Bar Poke Cake Recipe
Step 1: Prepare Your Pan and Oven
Start by preheating your oven to 350°F (175°C). Then, generously spray a 9×13-inch baking pan with nonstick cooking spray to make sure your cake lifts out easily after baking. This simple prep step ensures even cooking and easy cleanup.
Step 2: Mix the Batter
In a large bowl, whisk together the vanilla cake mix, eggs, and water until you have a smooth, lump-free batter. You want it just combined so the cake comes out tender, not dense. This step is quick and sets the stage for a perfect, moist dessert.
Step 3: Bake Until Golden
Pour the smooth batter evenly into your prepared pan. Bake in the oven for about 30 minutes, or until a toothpick inserted in the center comes out clean. This check ensures your cake is baked through but still retains moisture—exactly what you want for soaking up all those delicious toppings.
Step 4: Poke Holes for Maximum Flavor
Once the cake is out of the oven and slightly cooled, grab a fork or skewer and gently poke holes across its entire surface. This technique is the heart of the Heath Bar Poke Cake Recipe because it lets the sweetened condensed milk and chocolate syrup seep deeply into the cake, making every bite rich and moist.
Step 5: Drizzle Sweet Goodness
Slowly pour the can of sweetened condensed milk followed by the chocolate syrup evenly over the warm cake. The liquid will pool in the holes and soak into the crumb, creating a luscious, velvety texture that makes this poke cake truly irresistible.
Step 6: Chill and Frost
Pop your cake in the refrigerator for at least one hour. Chilling helps set the flavors and makes the cake firmer for frosting. When chilled, spread the Cool Whip evenly over the top for a light, creamy finish. Sprinkle Heath Bar bits and milk chocolate shavings generously on top to add the perfect crunch and extra chocolate appeal.
Step 7: Slice and Serve
Cut your Heath Bar Poke Cake into squares and serve at room temperature or chilled for a cool, dreamy treat. Watch how the gooey layers and crunchy toppings come together for a mouthwatering dessert everyone will rave about.
How to Serve Heath Bar Poke Cake Recipe

Garnishes
For garnishes, keep it simple but indulgent. Adding a few extra Heath Bar bits on top right before serving amps up the crunchy texture, while a light dusting of cocoa powder or powdered sugar can add a beautiful finishing touch. Top with a fresh strawberry or a dollop of whipped cream if you want to elevate the look and taste.
Side Dishes
This Heath Bar Poke Cake pairs beautifully with a scoop of vanilla ice cream or a drizzle of caramel sauce on the side for a decadent experience. A rich cup of coffee or a glass of cold milk can also balance the intense sweetness perfectly, making your dessert time feel truly special.
Creative Ways to Present
Looking to impress? Serve slices in clear dessert dishes to showcase the moist layers soaked with chocolate and condensed milk. You can also cut the cake into smaller squares and place them on a decorative platter with Heath Bar bits scattered artistically around for a stunning presentation. Another fun idea is to serve mini poke cakes in mason jars topped with additional cool whip and candy bits for individual portions.
Make Ahead and Storage
Storing Leftovers
Store any leftover Heath Bar Poke Cake in an airtight container in the refrigerator. It will stay fresh and moist for up to 4 days. The topping may cause the cake to soften further, which means the flavors meld and deepen—sometimes leftovers taste even better!
Freezing
If you want to save the goodness for later, freeze the cake slices (preferably without the Cool Whip topping) wrapped tightly in plastic wrap and then in a freezer-safe container. They will keep well for up to 2 months. Thaw in the refrigerator overnight before adding fresh topping and garnishes.
Reheating
Since this cake is best enjoyed chilled or at room temperature, reheating isn’t necessary. However, if you prefer a slightly warmer bite, briefly warm a slice in the microwave for 10-15 seconds, but avoid melting the Cool Whip topping. Enjoy the contrast of the warm cake and cool frosting—it’s delightful!
FAQs
Can I use homemade cake instead of box mix?
Absolutely! Using your favorite homemade vanilla cake recipe can add a personal touch. Just make sure it’s moist and sturdy enough to hold the condensed milk and syrup soak without falling apart.
What if I don’t have Heath Bar bits?
If you can’t find Heath Bar bits, crushed toffee bars or even chopped caramel candies make a great substitution. They will still add that yummy crunch and toffee flavor this poke cake is loved for.
Is this cake gluten-free?
The traditional recipe uses a regular boxed cake mix which is not gluten-free. For a gluten-free version, look for a certified gluten-free vanilla cake mix and verify that all other ingredients meet your dietary needs.
Can I make this recipe dairy-free?
To make it dairy-free, opt for a dairy-free cake mix, substitute the sweetened condensed milk with a coconut condensed milk variety, and use a dairy-free whipped topping. Keep in mind the flavor and texture will vary slightly but still be delicious.
How important is the chilling step?
Chilling really helps the flavors meld together and makes the cake firmer for slicing and serving. While you could serve it sooner, the texture and overall enjoyment improve significantly after at least an hour in the fridge.
