Tips for making the best s’mores poke cake
This recipe calls for having a chocolate cake already baked in a 9x13" baking dish. Use a chocolate cake mix that has the ingredients to do this or you can use an already baked cake (easy hack).
More helpful tips for you.
- Make sure that you allow the cake cool completely before poking holes and adding the pudding layer. If the cake has not fully cooled the pudding will not set properly in the cake.
- The fluff frosting layer should be 'dropped in dollops' on to the cake rather than just spread on to the cake from the bowl. This will make it easier to spread the frosting as it 'sticky' by nature.
- I like to top a cake such as this one just before serving. This allows the graham cracker crumbs and chocolate pieces to stay crisp and without softening in the refrigerator.
