Ingredients

For the Apple Mouths

• 1 large Red Delicious apple
• ¼ cup creamy peanut butter (60 g)
• Mini marshmallows, as needed for the teeth

Red Delicious apples are the approved apple choice for this version. Choose one that is firm, fresh, and free from bruises so the slices hold together.

For the Optional Fruit Dip

• 1 6-oz container orange crème yogurt (170 g)
• ½ cup marshmallow creme (about 128 g)
• 4 oz cream cheese, softened (113 g)
• 1 tsp vanilla extract (5 mL)
• Edible candy eyes, for decorating

The cream cheese should be softened at room temperature so it blends smoothly with the yogurt and marshmallow creme.

How to Make This Recipe

Step 1: Prepare the Fruit Dip

Add the orange crème yogurt, marshmallow creme, softened cream cheese, and vanilla extract to a medium mixing bowl. Use a handheld mixer to blend until the mixture is smooth and thoroughly combined. If using edible eyes, place them on top of the dip just before serving.

Step 2: Cut the Apple

Cut the apple into quarters and remove the core piece from each quarter. Then cut the quarters into smaller slices. Keep the slices sturdy enough to handle and avoid cutting them paper-thin.

Step 3: Add the Peanut Butter and Teeth

Spread about 2 tsp of creamy peanut butter onto each apple slice. Place a row of mini marshmallows across one peanut-buttered slice. The peanut butter acts as the adhesive, so use enough to hold the marshmallows without covering the entire apple.

Step 4: Assemble and Serve

Place another apple slice over the marshmallow layer and press gently until the pieces adhere. Arrange the finished apple mouths on a serving plate and serve immediately with the optional fruit dip.

Pro Tip: Assemble the mouths close to serving time. The apples are crispest when fresh, while the marshmallows become softer after refrigeration.

Expert Tips for Better Results

• Use a firm Red Delicious apple so the slices stay intact during assembly.
• Remove the core carefully; hard core pieces can make the mouths uncomfortable to eat.
• Spread the peanut butter evenly so the marshmallows stay in place.
• Press the two apple slices together gently rather than squeezing out the filling.
• Serve the apple mouths immediately for the freshest texture.
• If preparing the fruit dip ahead, keep it covered and refrigerated until serving.

Serving Suggestions

• Serve the apple mouths on a Halloween platter alongside the optional orange fruit dip.
• Add them to a children’s snack table with other fresh fruit for color and crunch.
• Pair them with popcorn or pretzels for a casual Halloween movie night.
• Serve them after school before trick-or-treating.
• Place the dip in a small bowl in the center of the platter so guests can dip each apple mouth easily.

Storage and Reheating

• Serve the apple mouths immediately whenever possible for the crispest apples.
• Tightly wrap leftover apple mouths and refrigerate them for a few days.
• Expect the apples to begin browning slightly during storage.
• Refrigerated marshmallows will soften over time.
• Store leftover fruit dip in a sealed container in the refrigerator for up to 3 days.
• Stir the fruit dip before serving again.
• Freezing is not recommended because frozen and thawed apples become soft and watery.
• Reheating is not applicable; these are served cold or at room temperature.
