Ingredients for easy oatmeal cookies

• Oats: 150 g (about 1 1/2 cups)
• Sugar: 50 g (about 1/4 cup)
• Butter: 113 g (1/2 cup), softened
• 1 egg
• Flavoring: 1/2 tsp (vanilla sugar, vanilla extract, or a pinch of cinnamon or cardamom)

Optional toppings: chopped nuts, raisins, dried cranberries, or chocolate chips.

How to make the best oatmeal cookies

This recipe uses coarsely ground oats. Pulse the oats briefly in a food processor or blender so they are broken up but still have texture. That gives the cookies structure while keeping them tender.

1. Prepare the oatmeal cookie dough

In a mixing bowl, cream together the softened butter and sugar until smooth and uniform. Add the egg and mix until combined. Stir in your chosen flavoring—vanilla is classic, while cinnamon or cardamom add warm spice.

Fold in the coarsely ground oats and mix until the mixture comes together into a thick cookie dough.

2. Shape the oatmeal cookies

This dough is thick and won’t spread much while baking, so there’s no need to chill it. Scoop portions using a tablespoon or a small ice-cream scoop. Lightly grease the scoop or spoon so the dough releases easily.

Place the scoops on a parchment-lined baking sheet, leaving about an inch between each cookie to allow for slight puffing. Press a few chocolate chips, nuts, or raisins on top, if desired.

Topping ideas: chocolate chips for a classic favorite, raisins for oatmeal-raisin style, or chopped nuts and dried fruit for extra texture and flavor.

Bake the cookies

Preheat the oven to 375°F (190°C). Bake the cookies for 12–14 minutes, adjusting time for cookie size—larger cookies need a bit longer. They may look slightly underdone when removed; that’s normal. Let them cool on the baking sheet for 3–4 minutes, then transfer to a wire rack to finish cooling. Cookies will firm up as they cool and remain soft inside.

Tips for softer, chewier cookies

Swap brown sugar for white sugar to create a moister, chewier texture. Brown sugar adds moisture and a slight caramel flavor that pairs well with oats.

Make the dough ahead

You can refrigerate the dough, covered, for up to 2 days. Allow it to come to room temperature before scooping and baking for best results.

Freeze cookie dough for quick baking

Shape the dough into spoonfuls on a parchment-lined sheet and freeze until firm. Transfer the frozen portions to a freezer bag or container; they’ll keep for up to six weeks. When ready to bake, place frozen scoops on a baking sheet, let them sit at room temperature a few minutes while the oven preheats, then bake as directed. This gives you freshly baked cookies any time.
