Single-Serve Oatmeal Cookie (No Egg, One Bowl)

A Single Oatmeal Cookie Without an Egg

This small-batch oatmeal cookie makes one generous cookie with no mixer and no leftover dough. Rolled oats provide chew, brown sugar keeps the centre soft, and melted butter brings the dough together without needing an egg. Make it in the oven for a lightly crisp edge, or use the microwave when speed matters more than browning.

Why This Recipe Works

The combination of oats and a small amount of flour gives the cookie structure while leaving it pleasantly chewy. Baking powder provides a little lift so the cookie does not become heavy, and the tablespoon of milk hydrates the dry ingredients without making the dough loose. Resting the cookie for a few minutes after cooking is important because the centre firms as it cools.

Oven Method

The oven gives the best texture and flavour: a lightly golden edge with a soft middle. Flatten the dough before baking because the small amount of leavener will not spread it dramatically. Bake only until the edges are set and lightly coloured; the centre should still look a little soft when it comes out.

Microwave Method

The microwave is useful when you want a cookie in about a minute, but it will be softer and paler than the oven version. Use a microwave-safe plate, flatten the dough evenly, and cook until the surface looks set. Let it stand for at least one minute before eating. Avoid overcooking, as the oats become firm quickly.

Variations

Add the optional tablespoon of chocolate chips, raisins, or chopped nuts. A pinch of cinnamon or nutmeg suits the brown sugar and oats. Peanut butter can replace part of the melted butter, but the dough will be denser and the flavour more pronounced. For a dairy-free version, use plant-based milk and coconut oil or a dairy-free block alternative.

Storage and Serving

This recipe is designed to be eaten fresh and does not make enough dough to be useful for batch storage. If needed, keep the cooked cookie covered at room temperature for one day. Warm it briefly before serving, but expect the texture to be softer than when freshly baked.

The nutrition estimate is for the base cookie without optional add-ins. Butter, sugar, and add-ins can change the calories and fat substantially, so treat the figures as approximate.
