About This Recipe
This is a backyard-friendly riff on campfire caramel apples: apple halves seared on a two-zone grill, spooned with a quick, buttery caramel, and finished with toasted marshmallow and a crunchy crushed-candy scatter. The contrast is what makes these boats sing — the apple’s bright, slightly tart flesh, the warm sticky caramel that nestles in the cavity, a soft browned marshmallow cap, and shards of toffee, peppermint or chocolate for textural snap. Using Fuji or Honeycrisp keeps the boats firm through the searing step while still yielding a tender bite.
The technique is intentionally simple so you can scale it for a party: a fast stovetop caramel, a short direct sear to get smoky caramelization, then gentle indirect heat to finish. Little touches — a pinch of flaky sea salt, a splash of bourbon, or a ramekin of melted chocolate for dunking — turn each boat into a grown-up treat without complicating the workflow. These are great for cookouts, kids’ parties (skip the booze), or as an approachable dessert when you want something warm, handheld, and a little theatrical straight from the grill.
Ingredients for Grilled Caramel Apple Boats with Candy Crunch
- 4 medium Medium apples (Fuji or Honeycrisp)
- 2 tablespoons Unsalted butter
- 1 teaspoon Ground cinnamon
- 12 count Large marshmallows
- 1/2 cup Crushed candy mix (toffee, chocolate bars, peppermint, or similar)

How to Make Grilled Caramel Apple Boats with Candy Crunch
Step 1: Halve and hollow the apples; prep toppings
Active 12 min
Halve 4 medium apples lengthwise to make 8 apple boats. Use a small spoon or melon baller to scoop a shallow cavity (leave about 1/4" of flesh so the boat keeps its shape). Toss the cut sides with melted butter and the cinnamon so they’re lightly coated. Arrange the marshmallows and the crushed candy in small bowls for easy filling later.For this step
- 4 mediumMedium apples (Fuji or Honeycrisp)
- 2 tablespoonsUnsalted butter
- 1 teaspoonGround cinnamon
- 12 countLarge marshmallows
- 1/2 cupCrushed candy mix (toffee, chocolate bars, peppermint, or similar)
Step 2: Make the quick caramel (or use a shortcut)
Active 10 min · Passive 5 min
In a small saucepan over medium heat, melt the 2 tablespoons butter with 1/2 cup packed brown sugar and 1/3 cup heavy cream, stirring until the sugar dissolves and the mixture thickens slightly (about 4–6 minutes). Remove from heat and stir in the optional 2 tablespoons bourbon and 1/4 teaspoon flaky sea salt off the flame to finish. If you’re short on time, substitute about 1/2 cup store-bought caramel sauce warmed briefly (not listed) and stir in the bourbon and salt if you like.For this step
- 1/2 cupPacked brown sugar
- 1/3 cupHeavy cream
- 2 tablespoonsBourbon (optional)
- 1/4 teaspoonFlaky sea salt
Step 3: Set up a two-zone grill and sear apple boats
Active 8 min · Passive 10 min
Build a two-zone fire (gas: light one side to medium-high, keep the other side off; charcoal: bank coals to one side). Clean and oil the grate. Place apple boats cut-side down over the direct heat to get a nice char—watch carefully and sear 3–4 minutes until caramelized, then move the apples to the cooler indirect side to finish cooking for 6–8 minutes with the lid closed so they soften but hold their shape.Step 4: Fill, toast marshmallows and finish on the grill
Active 8 min
Return each apple boat to the grill indirect zone cut-side up. Spoon a generous tablespoon (or more) of the warm caramel into each cavity, top with 1–2 marshmallows and close the lid just long enough—about 1–2 minutes—for the marshmallows to soften and brown but not burn. Remove, immediately sprinkle with the crushed candy, a pinch more flaky sea salt to taste, and offer the optional warmed semisweet chocolate chips for dipping (melt chips in a small heatproof bowl over the grill or on the stove).For this step
- 4 ouncesSemisweet chocolate chips (optional for dipping)
Step 5: Plate, serve and optional boozy twist
Active 2 min
Serve warm directly from the grill—each apple makes one boat; this recipe yields 8 apple boats. For a boozy variation, drizzle another teaspoon of warmed bourbon into each caramel bowl before topping or stir 1 teaspoon of bourbon into the warmed store-bought caramel shortcut; keep extra bourbon out of reach of children. Suggested mix-ins: chopped toasted pecans, a smear of peanut butter in the cavity before filling, or a sprinkle of cinnamon-sugar.

Grilled Caramel Apple Boats with Candy Crunch Tips
Pick firm apples
Use Fuji or Honeycrisp so the boats hold their shape during searing and don't turn mushy when moved to indirect heat.
Hollow with care
Leave about a quarter-inch of flesh around the cavity to prevent collapse; a melon baller or small spoon gives a neat, even bowl.
Manage marshmallow browning
Do the marshmallow finish on the indirect side with the lid closed for 1–2 minutes to soften and brown without burning or flare-ups.
Watch the direct sear
Sear cut-side down just 3–4 minutes over medium-high heat and keep a close eye for flare-ups — swivel or lift if flames spike.
Finish caramel texture
If your caramel seems thin, simmer another minute or two off the heat to concentrate it; it should be spoonable but still pourable.
Grilled Caramel Apple Boats with Candy Crunch Variations and Substitutions
Dairy-free caramel
Substitute canned coconut cream for heavy cream and use coconut oil instead of butter to make a rich, dairy-free caramel that still sets nicely.
Nutty praline finish
Mix chopped toasted pecans or almonds into the crushed-candy topping for extra crunch and toasty flavor.
S'mores-style swap
Use crushed graham crackers and extra semisweet chocolate chips on top for a s'mores-inspired boat instead of the candy mix.
Maple-bourbon twist
Replace half the brown sugar with maple syrup and stir 1 tablespoon of bourbon into the caramel for a deeper, boozy note (omit for kids).
How to Store and Make Grilled Caramel Apple Boats with Candy Crunch Ahead
Store leftover apple boats in an airtight container in the refrigerator for up to 2 days; note the marshmallow topping will soften and the candy may draw moisture. To reheat, warm them gently on the grill set to low or in a 325°F oven for 6–8 minutes, then refresh the marshmallow under the broiler briefly or torch it for a revived toasted top. Make the caramel up to 3 days ahead and rewarm over low heat before assembling.
What to Serve With Grilled Caramel Apple Boats with Candy Crunch
Serve warm with a scoop of vanilla ice cream or a drizzle of extra warmed caramel for contrast between hot and cold. Pair with hot spiced apple cider, coffee, or a smoky bourbon cocktail; for kids, offer milk or warm cocoa. Present on small plates with ramekins of melted chocolate for dipping to make these feel like an interactive dessert station.
Grilled Caramel Apple Boats with Candy Crunch FAQs
Can I make these in the oven instead of on the grill?
Yes — roast the hollowed apple halves cut-side up at 375°F for 18–22 minutes until tender, then broil briefly to toast the marshmallows, watching closely to prevent burning.
My marshmallows browned too fast — how do I avoid burning?
Move the apples to indirect heat and close the lid for 1–2 minutes; if you must use direct heat, keep the distance from the flame greater or toast with a kitchen torch to control browning.
Can I prep anything ahead to save time at the grill?
Yes — make the caramel up to 3 days ahead and store refrigerated, hollow the apples and toss them with lemon or the butter-cinnamon mix shortly before grilling to prevent browning.
Will the candy topping stay crunchy?
It will soften over time as it absorbs moisture from the hot caramel and apples, so sprinkle the crushed candy right before serving for maximum crunch.
Is there a way to make these kid-friendly?
Omit the bourbon and offer melted chocolate or extra caramel as a dipping sauce; use milder candies like crushed toffee or cookie crumbs instead of peppermint if preferred.
