Oatmeal Cookie in a Mug

This Oatmeal Cookie in a Mug offers a quick way to bake one individual cookie using gluten-free flour, coconut sugar, and oats. The mixture combines melted coconut oil with baking soda and optional vanilla and chocolate chips for added flavor. Once microwaved, it yields a soft, warm cookie with a simple oatmeal texture, perfect for a small indulgence without baking an entire batch.

Description

The recipe creates a single-serving oatmeal cookie by mixing gluten-free flour, quick oats, coconut sugar, baking soda, melted coconut oil, water, a pinch of sea salt, and optionally, vanilla extract and chocolate chips. Ingredients are stirred together in a microwave-safe mug or cup and cooked in the microwave until set.

The resulting cookie has a soft consistency with the subtle chewiness of oats and a mild sweetness from coconut sugar. The coconut oil adds moistness and richness. Chocolate chips provide bursts of chocolate flavor, making it a customizable treat for one.

This mug cookie is suited to those wanting a quick, portion-controlled dessert or snack without needing an oven or batch baking. It’s convenient for solo servings or testing gluten-free flour blends. Cooling briefly before eating improves texture and safety.

Ingredients

Servings
  • 1/4 cup all-purpose flour gluten-free
  • 3 Tbsp coconut sugar
  • 1/8 tsp baking soda
  • 2 Tbsp quick oats
  • 3 Tbsp coconut oil melted
  • 1 Tbsp water
  • pinch salt sea salt

Optional Add-ins

  • 1/4 tsp vanilla extract pure
  • 1 to 2 Tbsp chocolate chips

Instructions

  1. Add all ingredients in the order in which they appear to a microwave-safe mug or measuring cup. Stir in the chocolate chips (if adding).
  2. Microwave on high 40 to 60 seconds, until cookie has set up.
  3. Allow cookie to cool for 1 minute before enjoying.

Notes

  • Gluten-free flour blends absorb liquid differently; Bob's Red Mill 1-to-1 flour works well, while Pamela's may result in a greasier cookie.
  • For a smaller microwave cookie, reduce ingredient amounts proportionally and microwave for 60 seconds.
