How to Make Spiced Apple Dump Cake on the Grill

Preheat the grill: Heat grill to 350°F.

Heat the skillet: Place a cast-iron skillet on the stove over low heat until hot to the touch. Lightly grease with butter or oil.

Layer the apples: Pour apple pie filling into the skillet and stir in apple juice. Spread evenly across the bottom.

Add the cake mix: Sprinkle the dry spiced cake mix evenly over the apples. Pat down gently with a spoon.

Top with butter: Cut the stick of butter into ¼-inch slices and place across the surface of the cake mix, covering as much as possible.

Bake on the grill: Place the skillet on the grill, close the lid, and bake at 350°F for 1 hour.

Finish and serve: Remove from the grill.

Drizzle with sea salt caramel, and let rest for 5 minutes.

Serve hot with a scoop of ice cream.

Serving Suggestions

This Spiced Apple Dump Cake is best enjoyed warm, fresh off the grill. Here are some fun ways to serve it up:

• With Ice Cream: A scoop of vanilla, cinnamon, or butter pecan ice cream takes this dessert to the next level as it melts into the warm, gooey cake.
• Drizzled & Dusted: Add a drizzle of caramel sauce and a sprinkle of powdered sugar for a bakery-style finish.
• Family-Style: Serve straight from the cast-iron skillet for a rustic, crowd-pleasing presentation. Just set it on the table and let everyone dig in!
• Paired with Drinks: A hot cup of apple cider, chai tea, or even a strong cup of coffee makes the perfect companion. For adults, try a warm spiced rum cider.
• BBQ Finale: This cake makes an incredible ending to a barbecue feast—serve it after smoked brisket or grilled chicken for the ultimate sweet finish.

Notes:

• This cake works beautifully in the oven too—bake at 350°F for 50–60 minutes.
• Try switching up the filling! Peaches, cherries, or even pears pair wonderfully with the spiced cake mix.
• For a little crunch, sprinkle chopped pecans or walnuts on top before baking.
