Sugar Free Low Carb Keto Cannoli Mug Cake for Two is a perfectly portioned dessert for any night of the week that still satisfies your sweet tooth — without the sugar crash.

Cannoli Keto Mug Cake

If you’ve ever found yourself craving something sweet late at night, standing in the kitchen wondering if it’s worth baking an entire cake just to satisfy that craving, this Sugar-Free Low Carb Keto Cannoli Mug Cake for Two is exactly what you need.

This recipe was first published back in 2015, and it’s still one of my most popular low-carb desserts today — which honestly makes me smile because at the time, keto mug cakes weren’t everywhere yet.

In fact, layering mug cakes into an actual “mini cake” wasn’t something I saw many bloggers doing at all back then. It was one of those why hasn’t anyone done this yet? moments.

Fast forward years later, and mug cakes are everywhere — but this one still stands out because it’s perfectly portioned, quick, satisfying, and tastes like a true Italian cannoli-inspired dessert without the sugar overload.

If you’re someone who struggles with sweet tooth cravings, blood sugar balance, or portion control — especially at night — this recipe was made for you.

Why Keto Mug Cakes Are One of My Favorite Low-Carb Desserts

I’ve been creating sugar-free, low-carb, and keto recipes for nearly two decades now, and keto mug cakes remain one of my favorite tools for long-term success.

Here’s why:

• They’re perfectly portioned desserts

• No leftovers sitting on the counter calling your name

• Quick enough to make even on a busy weeknight

• Ideal for people learning to balance blood sugar

• Great for anyone coming off my 30-day sugar elimination diet or sugar detox

Instead of baking a full cake and relying on willpower, mug cakes help you work with your biology, not against it.

This keto cannoli mug cake part is divided into 4 servings and truly fulfills that sweet tooth craving without turning into an all-night grazing situation.

And because this recipe makes two layers, it feels special — like a real dessert — not just “diet food in a mug.”

A Note on Cake Decorating (or Lack Thereof)

I’ll be honest — I am not a cake decorator.

Never have been. No ambition to become one. I care far more about taste, texture, and ingredients than whether my frosting is perfectly smooth. Give me creamy frosting, plop it on, add toppings, and I’m happy.

So if your layered mug cake looks a little rustic? Perfect. We’ll call it artisan. 😉

I feel no shame in calling myself a lame cake decorator. It’s an art and clearly a skill I have not mastered. Does it mean my cake is anything else than amazing in taste, certainly not. So I hope you can look past the flaws.

Microwave OR Oven Directions — Your Choice

One of the best parts about this sugar-free low carb cannoli mug cake is that you can make it in the microwave OR the oven, depending on what you prefer.

Microwave Directions

Perfect when you want dessert now.

• Mix the dry ingredients in a bowl

• Add the wet ingredients and whisk

• Pour into greased ramekins

• Microwave one at a time for about 1 minute each

You’ll have two small cakes ready in under 2 minutes total.

Oven Directions

Ideal if you don’t use a microwave or want a slightly firmer texture.

• Preheat oven to 350°F

• Bake for 10 minutes

• Let cool completely before frosting

Both methods work beautifully — choose what fits your lifestyle.

Coconut Flour vs Almond Flour in Mug Cakes

This recipe uses coconut flour, which behaves very differently than almond flour.

Coconut flour:

• Is more absorbent

• Requires fewer dry ingredients

• Creates a lighter, sponge-like texture

• Works well for microwave baking

Almond flour mug cakes tend to be heavier and oil-dense, and some people say a bit “grainy”, while coconut flour allows this cake to stay light — perfect for layering.

Tools to Make Low Carb Keto Mug Cake

Glass mixing bowls-Having a glass mixing bowl set of multiple sizes is really useful because they can go in the microwave or over a sauce pan of simmering water to melt chocolate or anything else. 

Shallow Quiche Ramekins– These quiche ramekins make layering a mug cake much easier as they are flatter then using a standard sized ramekin. 

Cake Decorating Turntable-If you want to decorate better than I have, it’s best to just invest in a nice turntable with appropriate spatulas for decorating. 

Cannoli Flavor Without the Sugar

Traditional cannoli filling relies heavily on sugar. This version keeps the classic cannoli flavor using:

• Almond extract

• Liquid stevia

• Creamy cannoli frosting

• Optional sugar-free chocolate chips

• Chopped pistachios (traditional for cannoli)

You can customize the frosting based on your needs — dairy-free, nut-free, or classic cream cheese-based.

Sugar-Free Frosting Options

Nutrition information does not include frosting, since you can choose what works best for you.

Popular options:

• Vanilla Cream Cheese Frosting
• Vanilla Butter Cream Frosting
• Chocolate Buttercream Frosting
• Peanut Butter Buttercream Frosting
• Cannoli Frosting

This cake is essentially a neutral low-carb base, which makes it incredibly versatile.

Why This Recipe Still Matters Today

This isn’t just a mug cake.

It’s a reminder that you don’t need to eliminate dessert to be healthy — you just need better options. Perfectly portioned desserts like this help you enjoy food while still supporting long-term health, blood sugar balance, and sustainability.

That’s why this is my favorite keto dessert recipe that has stood the test of time — and why it’s still just as relevant today as it was in 2015.
