Ingredients
For the Base:
- 1 cup quick oats
- 1/2 cup unsweetened applesauce
- 1/4 cup light butter or butter substitute
- 1/4 cup brown sugar substitute (e.g., Truvia, Swerve Brown)
- 1/2 teaspoon vanilla extract
For the Topping:
- 1 1/2 cups mini marshmallows
- 1/4 cup mini M&M’s (or sugar-free chocolate candies for fewer points)
- 1/4 cup semi-sweet chocolate chips
- 1 teaspoon coconut oil
Instructions
Prepare the Base
- Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper.
- In a large mixing bowl, combine quick oats, applesauce, light butter, brown sugar substitute, and vanilla extract. Mix until a soft dough forms.
- Press the mixture evenly into the prepared baking pan. Bake for 10-12 minutes or until the edges are lightly golden. Remove and let cool.
Create the Topping
- Spread the mini marshmallows evenly over the cooled oat base.
- In a microwave-safe bowl, combine semi-sweet chocolate chips and coconut oil. Microwave in 15-second intervals, stirring each time until smooth.
- Drizzle the melted chocolate over the marshmallows, ensuring an even coating.
Add the M&M’s
- Sprinkle the mini M&M’s over the melted chocolate while it’s still warm so they stick.

Slice and Serve
