Start your campfire or heat up your grill so that your heat source is ready. If using wood or charcoal, let the flames die out prior to heating your food.
Hull the strawberries and slice thinly. Cut your blueberries in half.
Sprinkle with sugar and toss lightly.
Cut six large pieces of foil and six slightly smaller pieces of parchment paper. Place one piece of parchment paper on top of each piece of foil.
Place one sixth of the fruit mixture on one piece of paper topped foil; continue with the rest of your food.
Wrap tightly to seal. Place packets on grate over coals.
After five minutes, flip packets over. Flip twice more for a total of 20 minutes over the heat.
While fruit is roasting, begin toasting slices of cake. We find it safest to toast fluffy cakes such as angel food inside a pie iron. However, for denser cakes such as pound cake you can do this by holding it over the fire on the long end of a s’mores stick or toasting fork. Alternatively, you can use a camp toaster.
When the cake is toasted, place on plate or tear into pieces and place in a bowl.
Carefully pull the packets off and let them cool for a minute or two. Open the seams (watch out for steam!) and pour the fruit over your toasted cake.
(Optional) Top your dessert with crème fraiche, whipped cream, or ice cream if desired.
Enjoy!
