Ingredients for a Basic Mug Cookie

You likely already have these in your kitchen! Here’s what you’ll need:

IngredientPurpose
All-purpose flourThe base that holds everything together
Brown sugarAdds moisture and a rich, caramel-like flavor
Granulated sugarBalances the sweetness and provides structure
Baking powderHelps the cookie rise in the microwave
Melted butterAdds richness and brings the dough together
Vanilla extractEnhances all the flavors
Chocolate chipsThe star of the show—gooey and melty
Salt (optional)A pinch enhances sweetness and balances flavors

Pro Tip: Use unsalted butter and adjust the salt separately for better control of flavor.


Step-by-Step Instructions

🥄 Step 1: Prepare Your Mug

Use a microwave-safe mug (ceramic or glass preferred) that’s at least 12 ounces. This allows space for the batter to rise without overflowing.

🥣 Step 2: Combine the Dry Ingredients

Add the following directly into your mug:

  • 3 tablespoons of all-purpose flour
  • ⅛ teaspoon of baking powder
  • A pinch of salt (if using)

Stir to combine.

🧈 Step 3: Add Wet Ingredients

Pour in:

  • 2 tablespoons of melted butter
  • 1 teaspoon of vanilla extract

Mix until the batter starts to come together.

🍬 Step 4: Add Sugars

Add:

  • 1 tablespoon brown sugar
  • 1 tablespoon granulated sugar

Stir well until everything is smooth and thick.

🍫 Step 5: Fold in Chocolate Chips

Add 2 tablespoons of chocolate chips. Gently fold them in using your spoon. You can also sprinkle a few extra chips on top.

🔥 Step 6: Microwave It

Microwave on high power for 40 to 60 seconds depending on your microwave’s wattage.

  • Start at 40 seconds and check with a toothpick.
  • If it’s still doughy, continue in 10-second intervals.

Note: The top might look slightly undercooked, but it’ll firm up as it cools.


Optional Add-In Ideas

  • 🥜 Peanut Butter Swirl – Add a teaspoon before microwaving for creamy goodness.
  • 🍌 Banana Bits – For a fruity twist and natural sweetness.
  • 🥥 Coconut Flakes – Add texture and a tropical vibe.
  • 🍪 Oreos – Crumble 1-2 Oreos into the mix for cookie-in-cookie action.
  • 🍫 Nutella Center – Drop a spoonful in the center before cooking. It melts into a gooey surprise.

How to Serve Your Mug Cookie

Your microwave cookie is best enjoyed warm and straight from the mug, but here are some fun serving suggestions:

🍨 1. With Ice Cream

Top your cookie with a scoop of vanilla or chocolate ice cream. The contrast between hot and cold is heavenly.

🍫 2. Drizzled with Sauce

Try caramel, chocolate syrup, or even a dash of honey for added richness.

🍓 3. With Fresh Fruit

Balance the sweetness with sliced strawberries, raspberries, or a few blueberries.


Common Mistakes to Avoid

Even simple recipes can go wrong if you’re not careful. Here’s what to watch out for:

❌ Using a Small Mug

Result: Overflow and a big microwave mess.

Fix: Always use a 12–16 oz mug.

❌ Overmixing the Dough

Result: Tough, rubbery texture.

Fix: Stir only until the ingredients are just combined.

❌ Overcooking

Result: Dry, hard cookie.

Fix: Microwave in short bursts and test early.

❌ Incorrect Measurements

Result: Cookie fails to rise or tastes off.

Fix: Use proper measuring spoons and cups.


Storage and Reheating

Though it’s a single-serve recipe, if you end up saving half:

  • Cool completely, then cover with foil or plastic wrap.
  • Store at room temperature for up to 2 days or refrigerate for up to 1 week.
  • Reheat in the microwave for 10–15 seconds. Be cautious not to overheat and dry it out.

Make-Ahead Tip

Create DIY Mug Cookie Mix Jars:

  • Mix dry ingredients (flour, sugar, baking powder) in small zip-lock bags or jars.
  • Add a tag with instructions for the wet ingredients.
  • Great for gifting or for busy nights when you want dessert—fast!

FAQs About Microwave Mug Cookies

❓ Can I make it gluten-free?

Yes! Substitute regular flour with a 1:1 gluten-free flour mix. Oat flour also works.

❓ Can I make it vegan?

Absolutely. Use plant-based butter and swap chocolate chips with dairy-free options. You can even use flaxseed meal as a binder.

❓ Is it safe to eat if slightly undercooked?

Yes, there’s no egg, so slightly gooey centers are safe and delicious!

❓ Can kids make this?

Yes! It’s a great beginner recipe for kids—with adult supervision for the microwave.
