Peanut Butter Cookie in a Mug
Description
This recipe cooks a peanut butter cookie directly in a microwave-safe mug, simplifying cleanup and preparation. Butter is melted first, then combined with peanut butter, maple syrup, and an egg yolk for moisture and richness. Vanilla adds flavor complexity, while flour and sea salt provide structure and seasoning. The resulting batter is thinner than usual cookie dough but cooks to a soft cookie quickly in the microwave.
The mug-baked cookie provides a fresh warm treat ideal for quick cravings or single servings without the need to bake a full tray. Adding chocolate chips before microwaving can introduce melty chocolate bites.
Ingredients
- 1 Tbsp butter unsalted
- 3 Tbsp peanut butter creamy
- 2 Tbsp pure maple syrup
- 1 egg yolk
- ½ tsp vanilla extract pure
- 2 ½ Tbsp all-purpose flour gluten-free or regular
- ⅛ tsp salt sea salt
Instructions
- Microwave the butter in a microwave-safe mug for 20 to 40 seconds, or until it has melted. Note: I prepare the cookie dough in a small bowl or a measuring cup first and then use a rubber spatula to transfer it over to a microwave-safe mug or ramekin. You can easily just use a mug for the whole process, which requires less cleanup.
- Add the peanut butter, pure maple syrup, egg yolk, and vanilla extract and mix well until everything is well-combined (wet ingredients). Note: If your peanut butter is very cold from having been sitting in the refrigerator, microwave it along with the butter to soften it up so that it stirs easily.
- Stir in the gluten-free all-purpose flour and sea salt (dry ingredients) and mix until a smooth batter forms. The mixture will be relatively thin and will not resemble regular cookie dough - this is normal! If you’d like, sprinkle the top with chocolate chips or mix some chocolate chips into the cookie dough.
- Microwave on high heat (the microwave’s default setting) for 45 to 60 seconds, or until it has set up. I recommend starting with 45 seconds then microwaving longer only if need be. Allow the mug to cool down for a minute or two before enjoying the peanut butter cookie - initially it will be very hot! The texture will look slightly crumbly but the cookie will melt in your mouth. Consider serving microwave peanut butter cookies with a scoop of ice cream or a glass of milk.
Notes
- Butter can be substituted with coconut oil, vegan butter alternatives, or avocado oil for dietary preferences.
- If peanut butter is cold and firm, warming it with the butter helps with mixing.
