Ingredients for Sugar Free Fudgy Keto Mug Brownie

Grab your favorite oversized coffee mug – we’re making magic happen! Here’s everything you’ll need for that perfect single-serve fudgy goodness:

• 2 tbsp almond flour – the fine, blanched kind works best
• 1 tbsp cocoa powder – go for the good stuff, not Dutch-processed
• 1 tbsp packed erythritol – press it into your measuring spoon
• 1/4 tsp baking powder – just a pinch makes all the difference
• 1 tbsp melted butter (or coconut oil for dairy-free) – trust me, this is where the richness comes from
• 1 tbsp unsweetened almond milk (any nut milk works) – the secret to perfect moisture
• 1/4 tsp vanilla extract – pure vanilla if you’ve got it
• 1 tbsp sugar-free chocolate chips (optional) – because why not?

Oh! And make sure you’re using a large mug (min. 8oz capacity) – learned that the hard way when mine overflowed. Oops!

How to Make Sugar Free Fudgy Keto Mug Brownie

Okay, let’s get to the fun part! I’ve made this so many times I could do it in my sleep, but here’s exactly how to nail it on your first try:

1. Mix the dry stuff first: Dump your almond flour, cocoa powder, erythritol, and baking powder right into the mug. Give it a good whisk – you want zero lumps hiding in there.
2. Add the wet ingredients: Pour in that melted butter (or coconut oil), almond milk, and vanilla. Now, here’s the key – stir just until combined. Overmixing makes it tough, and we want fudgy, not bouncy!
3. Fold in the goodies: Toss in those sugar-free chocolate chips if you’re using them. A few extra never hurt anyone, right?
4. Microwave magic: Pop it in for 60 seconds first. It should look set but still a bit shiny on top. If not, add 15-second bursts – microwaves vary wildly! Mine always needs exactly 72 seconds (yes, I timed it).
5. Wait (if you can): Let it sit for 2 minutes. I know, torture! But this lets the center finish setting up into that perfect spoonable texture.

Pro Tip for Perfect Texture

Undercook it slightly – that’s the secret! When testing with a toothpick, you want moist crumbs clinging to it, not clean. It’ll keep cooking as it cools. Trust me, this makes all the difference between fudgy and dry.

Customizing Your Sugar Free Fudgy Keto Mug Brownie

This recipe is like your favorite little black dress – perfect as is, but so fun to accessorize! Here are my go-to twists:

• Peanut butter swirl: Drop 1/2 tsp in after mixing and drag a knife through – it makes these gorgeous chocolatey ribbons
• Crushed nuts: Walnuts or pecans add the best crunch (toast them first for extra flavor!)
• Sea salt sprinkle: A tiny pinch of flaky salt on top makes the chocolate taste even richer

Honestly? Sometimes I do all three. No regrets.

Storing and Reheating Sugar Free Keto Mug Brownie

Let’s be real – this treat rarely lasts long enough to store! But if you must, it keeps well in the fridge for up to 2 days. Just nuke it for 10-15 seconds to bring back that gooey goodness. Warning: freezing turns it oddly spongy – learned that the hard way!
