Can I use regular flour instead of almond or coconut flour?
Stick with almond and coconut flour to keep the carbs low. Regular flour will change the texture and add a lot more carbs.
What can I substitute for ChocZero Maple Pecan Syrup?

How do I store leftovers of the mug cake?
Store in an airtight container in the fridge for up to 2 days. Reheat in the microwave for about 20 seconds.

Each serving has about 3.9g net carbs using the ingredients listed. Your count will shift slightly if you swap sweeteners or flours.
Mug cakes are made for those of us eating keto. We don’t always want lots of sweets lying around because they can trigger cravings. A single mug cake eliminates that problem. It’s portion controlled, single or double serving, and you can have it ready in minutes. Just mix everything together in a bowl, pour it into a mug, and microwave for less than 2 minutes.
Pecan pie in mug cake form is a perfect treat any time of year, but it’s especially good around the holidays when all the Thanksgiving and Christmas desserts get piled on the tables. You get all the yummy holiday flavors without the excess carbs.
And this one is to die for! Not only is it full of pecan pie flavor, but every bite of that warm buttery topping will send your fork going back for more.
In this recipe, I use Maple Pecan Syrup by ChocZero. ChocZero syrups are full of flavor with no sugars or sugar alcohols. I love using them in my baking.

This is amazing!!!! I could literally eat it everyday if I allowed myself, 🙂!
OMG! This was soooo delicious!!!! I ended up subscribing to your channel after coming across your recipe for 90 second keto bread! I have to say, by far, it's the BEST keto bread I've tasted and easy to make!!! Since I've started low carb again, I started looking for desserts to satisfy my sweet tooth and came across this recipe. I have to say, you wouldn't even know it was keto unless someone told you. And this is coming from someone who LOVES sweets with regular sugar! It was that delicious and by far one of my favorite desserts!!! I've made it three times already and it's easy to make! I can't wait to try your pecan cookie recipe. If the rest of your desserts are this delicious, I know I'll be successful on my weight loss journey! :-) Thank you for making this easy!
Love, love, love your recipes, you are an awesome "Keto Leader" and I appreciate all the recipes you share. It's fun to watch your videos and know we are all together trying to be proactive, get healthy and lose weight! Thanks for what you do.
This is an excellent recipe!! I made a delicious desert for my husband and I in less than 30 minutes.
Just made this. I'm a beginner but I've tried a few mug cakes and holy cow this was unbelievable. You know it's good when even non-keto dieters cant get enough (made one for my very picky foodie roommate). Thank you!! P.s. love your YT channel as well!
These are so good. making it two nights in a row.
Watch those calories. 600 calories for the whole thing. That’ll undo any diet. Use this as a splurge or once a week special or at least only eat half if you are trying for weight loss. I’m not so it’s all mine…occasionally.
This is delicious! I made these in 4 small ramekins. I needed about 50% more topping to cover all 4 small cakes. I had most ingredients on hand already. These were easy to assemble, too. We enjoyed a warm dessert within just a few minutes.
I would like to see total carbs on recipes. I am on a very strict 20gram total carb. Insulin resistant and overweight. I have lost over 30 pounds and off one med following the 20 total carb program. I just recently found your channel and enjoy it a great deal. Thank you!
