Preheat the oven according to your box mix.
Prepare your vanilla cake mix as directed by the box. Feel free to substitute the water for milk if the mix calls for it.
Once the mix is ready, add 5 tablespoons of the guava jelly or marmalade to the mix and stir to combine.
Evenly add your mix into a cup cake tray with liners in place.
Cook as directed by the package and until you can stick a knife or toothpick in the center and it comes out clean.
Remove from the oven and allow them to cool.
While your cupcakes are cooling, prepare the cream cheese frosting. To do so, add your room temperature cream cheese to a bowl and the sugar. Use a mixer to beat the cream cheese until it’s fluffy. Add the vanilla and mix. Slowly fold in the cool whip. Set aside.
Once your cupcakes are cooled, carefully cut out the center of the cupcake with a knife into a cone shape. Fill the inside with the guava jelly or marmalade. Top off with your cream cheese frosting and enjoy!
