Keto Espresso Tonic Iced Coffee

Hey there!

If you’re a coffee lover looking for something cool, bubbly, and totally refreshing, this keto espresso tonic is exactly what you need.

It’s got a punchy shot of espresso, a splash of tonic water, and a little twist of lime for a fancy coffee-shop vibe—without the sugar or carbs.

Perfect for a hot day or when you want to shake up your coffee routine.

Bonus?

It’s super easy to make!

Chill your tonic water – Using cold tonic keeps your drink extra crisp and bubbly.
Use fresh espresso – The foam layer (aka crema) adds a luxurious touch.
Pour slowly – When adding the espresso to the tonic, pour it over the back of a spoon for that pretty layered look.
Taste test the tonic – Not all sugar-free tonic waters are created equal! Pick one you love.
Kids’ version – Skip the espresso and just mix the tonic with a splash of lime juice for a fizzy mocktail.

No espresso machine? Use strong cold brew or instant coffee.
Don’t have tonic? Swap it for sparkling water with a squeeze of lime for a lighter version.
Want it sweeter? Add a few drops of your favorite keto-friendly sweetener.

Brew your espresso or coffee in advance and chill it in the fridge. This way, you can whip up your drink in seconds.

Instructions

Slowly pour 1/2 cup of tonic water into the glass.

If you want a layered look, pour the espresso slowly over the back of a spoon into the tonic.

Add a lime wedge to the rim and toss on a few coffee beans for decoration.

This is a drink best made fresh! If you do have leftover espresso, store it in the fridge in a sealed container for up to 24 hours.

This keto espresso tonic is so simple, fancy, and refreshing—it’s hard not to fall in love!
