Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
1 cup creamy peanut butter
1/2 cup unsalted butter, softened
1 cup brown sugar, packed
1/2 cup granulated sugar
2 large eggs
1 teaspoon vanilla extract
2 teaspoons baking soda
1/2 teaspoon salt
3 cups rolled oats
1 cup semi-sweet chocolate chips
3/4 cup candy-coated chocolate pieces
Directions
Preheat your oven to 180°C (350°F) and line two baking sheets with parchment paper.
In a large mixing bowl, cream together the peanut butter, softened butter, brown sugar, and granulated sugar until smooth and fluffy. This step ensures the cookies will have a soft and tender texture.
Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract to enhance the flavor.
Sprinkle in the baking soda and salt, then mix until fully incorporated.
Gradually add the rolled oats, stirring until the dough becomes thick and well combined. Fold in the chocolate chips and candy-coated chocolate pieces, distributing them evenly throughout the dough.
Using a cookie scoop or spoon, drop rounded portions of dough onto the prepared baking sheets, spacing them about 5 cm apart to allow for spreading.
Gently press each dough ball slightly to flatten the tops.
Bake for 10–12 minutes, or until the edges are lightly golden while the centers remain soft. Be careful not to overbake, as the cookies will continue to firm up as they cool.
Remove from the oven and let the cookies rest on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
Servings and timing
This recipe makes approximately 18 to 20 cookies, depending on the size of each scoop.
Preparation time is about 15 minutes, with a baking time of 10 to 12 minutes per batch. The total time from start to finish is roughly 30 minutes.
Variations
You can easily adapt this recipe to suit your taste. Swap the peanut butter for almond or sunflower seed butter if you prefer a different flavor or need a nut-free option. Add chopped nuts like walnuts or almonds for extra crunch. For a richer taste, use dark chocolate chips instead of semi-sweet. You can also mix in shredded coconut or dried fruit such as raisins for a unique twist. If you enjoy a hint of spice, a pinch of cinnamon can add warmth to the cookies.
Storage/Reheating
Store the cookies in an airtight container at room temperature for up to 5 days. They will remain soft and chewy if kept sealed properly.
For longer storage, place the cookies in a freezer-safe container and freeze for up to 2 months. Thaw them at room temperature before serving.
If you prefer warm cookies, reheat them in the microwave for about 10–15 seconds to restore their soft texture and bring out the melted chocolate.
