What is a Poke Cake?

A poke cake is a cake that has holes poked into it after baking. These popular cakes have holes that are filled with a variety of fillings, such as sweetened condensed milk, whipped cream, or fruit.

The holes are typically made with the end of a wooden spoon, large fork, or skewers, and the filling is simply poured over the top of the cake. It’s important to poke the holes while the cake is still warm, so that the filling can seep down into the entire cake easily. The result is a moist cake with a nice depth of flavor that extends throughout the sheet cake.

Poke cakes are named for the way you “poke” holes into the cake after it bakes, and then pour a filling over the top. This helps the cake to absorb more of the filling, giving it even more flavor.

Most poke cake recipes are a quick dessert that can be made ahead of time, which makes them super easy to make. And while I love a good from-scratch recipe, sometimes you just need something quick and easy!

Heath Bar Cake Recipe

This Heath Bar Poke Cake gets its name from the filling – a rich and creamy caramel sauce that is studded with Heath Bar pieces. The cake itself is a chocolate cake, which pairs perfectly with the caramel filling. And to top it all off, this cake is finished with a chocolate ganache made from heavy cream and dark chocolate.

The combination of flavors and textures in this Heath Bar Poke Cake is out-of-this-world good. The chocolate cake is moist and dense, the caramel filling is rich and gooey, and the chocolate ganache is dark and decadent. Trust me – this cake is worth every single calorie!

How to Make a Heath Bar Cake

This Heath bar cake recipe starts with a doctored-up box mix for the cake. Be sure to use a good quality chocolate cake mix for your cake – I love Duncan Hines German Chocolate Cake Mix. If you can’t find German Chocolate Cake Mix, any good quality chocolate cake mix will work just fine for your cake batter. I personally love making decadent cakes from box cake mixes, my Italian Cream Cake from Cake Mix is another reader favorite!

The secret to this Heath Bar poke cake is a mixture of hot fudge and caramel ice cream topping sauces. The ooey-gooey filling really takes this cake over the top!

To get started, you’ll follow the package directions to make the cake. Once your cake is baked, let your cake cool. Then use want to use the handle of a wooden spoon to poke holes all over the top of the cake. Be sure to go all the way down to the bottom of the cake pan.

Now it’s time for the filling! Pour half of the chocolate caramel mixture over the top of the cake, making sure to evenly distribute it over the holes.

Allow the cake to sit for a few minutes so that it can absorb the filling.

After the cake has had a chance to soak up the filling, spread on the Cool Whip frosting. Then sprinkle the crushed Heath Bars over the top.

Allow the cake to chill in the fridge for at least an hour before serving.

This cake is best served cold, so be sure to allow plenty of time for it to chill in the fridge.

When you’re ready to serve, just slice and enjoy!
