Chocolate Chip Cookie
In A Mug1 MINUTE!
Warm, gooey, soft-centred chocolate chip cookie — made in a single mug, in your microwave, in exactly 60 seconds. Dessert emergency solved.
It’s 10pm. You want something warm, sweet, and chocolatey — and you don’t want to bake a whole batch of cookies. This is that recipe. One mug, one minute, and you have a freshly baked chocolate chip cookie that’s warm and gooey in the centre and slightly crisp at the edges.
No oven needed. No mixing bowl. No waiting. Just you, a mug, and 60 seconds of microwave time.
☕ How a Mug Cookie Actually Works
The microwave heats the batter from the inside out — which is why mug cookies can be both done on the outside and still gooey in the centre at the same time.
Mix Dry
Flour, sugar, salt, baking powder — combine in the mug first with a fork
Add Wet
Butter, egg yolk, vanilla — stir into dry ingredients until just combined
Fold Chips
Press chocolate chips on top and gently fold through — don’t overmix
Microwave
60–90 seconds at full power — watch the edges set while centre stays soft
Rest & Eat
1 minute rest — the centre finishes from carry-over heat. Then eat directly from the mug
The Perfect Mug Cookie Recipe
The exact amounts that produce a gooey, not rubbery, chocolate chip mug cookie every single time
Chocolate Chip Cookie In A Mug
Makes 1 serving · 60–90 seconds · One mug only
Ingredients
- 3 tbsp (24g) all-purpose flour
- 2 tbsp (25g) granulated sugar
- 1 tbsp (12g) brown sugar, packed
- ⅛ tsp baking powder
- Pinch of salt (don’t skip — it deepens the flavour)
- 2 tbsp (28g) unsalted butter, melted
- 1 egg yolk (not the whole egg — crucial)
- ¼ tsp pure vanilla extract
- 2–3 tbsp (35g) chocolate chips
Method
- In a large microwave-safe mug, mix flour, both sugars, baking powder, and salt with a fork until combined
- Add the melted butter, egg yolk, and vanilla extract to the dry mixture
- Stir until just combined and no dry flour streaks remain — don’t overmix
- Fold in the chocolate chips — press a few extra on top
- Microwave on high for 60 seconds — check the centre. It should look slightly underdone
- If still very liquid in the centre, microwave in 10-second bursts until edges are set
- Rest 1 minute — the centre will finish setting from the heat. Eat immediately from the mug
The Technique That Makes It Perfect
Why each step matters — and the mistakes that make mug cookies rubbery, dry, or raw
Use Only the Egg Yolk — Not the Whole Egg
This is the single biggest difference between a rubbery sponge cake and a proper cookie texture. A whole egg in a mug cookie adds too much protein and liquid — it sets like a soufflé. The yolk alone provides richness, fat, and binding without the excess moisture and protein white of the egg white. If your mug cookie is always too rubbery, this is why.
Use Both White Sugar AND Brown Sugar
White sugar gives crispy edges and spread. Brown sugar (with its molasses content) gives chewiness, moisture, and a deeper, more complex flavour. Using only one type gives you either a dry crumbly result (white sugar only) or an overly dense, almost sticky centre (brown sugar only). The combination — just like in a real cookie recipe — creates the right balance.
Do NOT Overmix the Batter
Once you add the wet ingredients to the dry, stir only until combined — stop the moment you see no dry flour. Overmixing develops the gluten in the flour, which is what makes mug cookies tough and chewy in the wrong way. Ten to fifteen stirs maximum. The batter should look slightly rough, not perfectly smooth.
Microwave Time — Start at 60 Seconds, Not 90
Microwave wattage varies enormously — a 1200W microwave cooks significantly faster than an 800W one. Always start at 60 seconds and check. The edges should be set and the centre should look slightly underdone and glossy. If it’s still very liquid, add 10-second bursts. You can always add more time. You cannot uncook a mug cookie.
Rest for 1 Minute After Microwaving
The mug and the cookie are extremely hot immediately after microwaving. Resting for 1 minute does two things: it makes it safe to eat, and it lets the carry-over heat finish setting the centre from liquid to that perfect soft-gooey cookie consistency. Eating it immediately (even if you can) means the very centre is still unbaked batter.

Classic Chocolate Chip Mug Cookie 🍪
“The original — gooey, warm, chocolatey perfection in 60 seconds”
Ingredients
- 3 tbsp all-purpose flour
- 2 tbsp granulated sugar + 1 tbsp brown sugar
- ⅛ tsp baking powder + pinch of salt
- 2 tbsp melted butter
- 1 egg yolk + ¼ tsp vanilla extract
- 2–3 tbsp semi-sweet chocolate chips
Method & Tips
- Mix dry ingredients first, then wet
- Stir only until combined — do not overmix
- Press extra chips on top before microwaving for visual appeal
- Microwave 60 seconds — rest 1 minute before eating

Peanut Butter Chocolate Chip Mug Cookie 🥜
“Rich, nutty, incredibly filling — one of the best flavour combinations in existence”
Ingredients
- 3 tbsp all-purpose flour
- 2 tbsp granulated sugar + 1 tbsp brown sugar
- ⅛ tsp baking powder + pinch of salt
- 1 tbsp melted butter + 1 tbsp peanut butter (smooth)
- 1 egg yolk + ¼ tsp vanilla extract
- 2 tbsp semi-sweet or peanut butter chips
Method Notes
- Combine both butters before adding — they mix more evenly
- The peanut butter replaces half the regular butter
- The batter will be slightly thicker than the classic — this is correct
- May need 70–80 seconds (the PB makes it denser)
- Top with a swirl of extra peanut butter after cooking
Matcha White Chocolate Mug Cookie 🌿
“Earthy matcha meets sweet white chocolate — the most visually impressive and unique variation”
Ingredients
- 3 tbsp all-purpose flour
- 3 tbsp granulated sugar (no brown sugar — matcha has its own depth)
- 1 tsp matcha powder (ceremonial grade for best flavour and colour)
- ⅛ tsp baking powder + pinch of salt
- 2 tbsp melted butter
- 1 egg yolk + ¼ tsp vanilla extract
- 2–3 tbsp white chocolate chips
Method Notes
- Sift the matcha powder with the flour — lumps won’t dissolve in microwave
- Batter will be pale green — brighter green with ceremonial matcha
- White chocolate chips create sweet pockets that contrast the earthy matcha
- 60 seconds exactly — matcha mug cookies can easily overcook to a rubbery texture
Strawberry White Chocolate Mug Cookie 🍓
“Sweet, fruity, and bright — perfect for when you want something lighter and more summery”
Ingredients
- 3 tbsp all-purpose flour
- 3 tbsp granulated sugar
- 1 tsp freeze-dried strawberry powder (or 1 tbsp strawberry jam)
- ⅛ tsp baking powder + pinch of salt
- 2 tbsp melted butter
- 1 egg yolk + ¼ tsp vanilla extract
- 2 tbsp white chocolate chips
Method Notes
- Freeze-dried strawberry powder gives the most intense colour and flavour
- If using jam: reduce butter by ½ tbsp to compensate for the extra moisture
- The batter may look pink — this is exactly right
- 60 seconds — lighter flavoured mug cookies are more prone to overcooking
- Finish with a drizzle of warm white chocolate for presentation
Espresso Mocha Mug Cookie ☕
“Dark, intense, coffee-forward — for when you want a dessert that tastes as grown-up as you feel”
Ingredients
- 3 tbsp all-purpose flour
- 1 tbsp granulated sugar + 2 tbsp brown sugar
- 1 tsp instant espresso powder
- 1 tbsp good-quality cocoa powder
- ⅛ tsp baking powder + pinch of salt
- 2 tbsp melted butter
- 1 egg yolk + ¼ tsp vanilla
- 2 tbsp dark chocolate chips (70%+)
Method Notes
- Whisk espresso powder and cocoa with dry ingredients until no lumps
- The batter will be very dark — almost black — this is correct
- Use dark chocolate (70%+) chips — milk chocolate is too sweet here
- 60–70 seconds — cocoa in batter can make it look done before it is
- Serve with a scoop of vanilla ice cream for a mocha brownie sundae experience
Salted Caramel Mug Cookie 🧂
“Sweet-salty, rich, utterly addictive — the mug cookie you’ll make twice in a row”
Ingredients
- 3 tbsp all-purpose flour
- 1 tbsp granulated sugar + 2 tbsp brown sugar
- ⅛ tsp baking powder + ¼ tsp salt (yes, more salt — it’s part of the flavour)
- 2 tbsp melted butter
- 1 egg yolk + ¼ tsp vanilla extract
- 1 tbsp caramel sauce (swirled into batter before microwaving)
- 2 tbsp semi-sweet chocolate chips
- Flaky sea salt for finishing
Method Notes
- Swirl caramel sauce in last — not fully mixed, just ribboned through
- The caramel creates a sticky, golden pocket in the centre during cooking
- 60 seconds — caramel can burn if overcooked
- Immediately after cooking: pinch of flaky sea salt on top
- Optional: drizzle extra warm caramel sauce just before eating

Troubleshoot — Common Problems
❌ The mug cookie is rubbery and spongy — not cookie-like at all
The #1 mug cookie problem — and the cause is almost always using a whole egg instead of just the yolk.
Use only the egg yolk. The egg white sets firm and rubbery when heated — just like the white of a hard-boiled egg. The yolk alone gives richness and binding without that spongy texture.
❌ The centre is completely raw and liquid even after 90 seconds
Most likely the mug is too large (the thin layer of batter can’t cook in the centre) or your microwave wattage is very low.
Use a smaller, narrower mug so the batter is deeper and more concentrated. If your microwave is under 800W, add 20–30 extra seconds. Check in 10-second bursts until just the very centre looks soft, not liquid.
❌ The cookie is tough and dry — almost like a bread roll
Overmixed batter (developed too much gluten) or overcooked in the microwave.
Mix only until combined — stop the moment you see no dry flour, even if the batter looks rough. Also start at 60 seconds and check — you can always add time but you can’t remove it.
❌ The cookie barely rises and is completely flat
Old baking powder that’s lost its potency, or the baking powder was skipped.
Test your baking powder: drop ½ tsp into hot water — if it bubbles vigorously, it’s good. If nothing happens, replace it. Even ⅛ tsp of fresh baking powder makes a noticeable difference to rise and texture in a mug cookie.
