Why You’ll Love This Recipe
You’ll appreciate how easy and fuss-free these cookies are to make. They require only one bowl, no mixer, and pantry-friendly ingredients. The cookies are naturally sweetened, customizable with your favorite fruit spread, and suitable for anyone looking for a lighter dessert option. They’re also great for people who dislike bananas, since applesauce does the job beautifully.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
rolled oats (old-fashioned) – 1 1/2 cups (150 g)
unsweetened applesauce – 1/2 cup (120 g)
fruit jam or preserves (no added oil) – 1/4 cup (about 60 g)
Directions
Preheat your oven to 350°F (180°C). Line a baking sheet with parchment paper.
In a mixing bowl, combine the rolled oats and applesauce. Stir until the oats are fully coated and the mixture looks thick and sticky. Let it rest for 5 minutes so the oats can absorb some moisture.
Scoop about 1 1/2 tablespoons of the mixture and roll it into a ball. Place it on the prepared baking sheet and gently flatten it with your fingers.
Use your thumb or the back of a small spoon to make an indentation in the center of each cookie. Fill each indentation with about 1 teaspoon of jam.
Bake for 12–15 minutes, until the cookies are set and lightly golden around the edges. Remove from the oven and let them cool on the baking sheet for 5 minutes before transferring to a rack to cool completely.
