Looking for a way to jazz up your dessert and love bold espresso flavor? This creamy coffee sauce is just what you need! Go ahead, pour it on warm brownies, a stack of pancakes, vanilla yogurt, or your next scoop of ice cream—you'll add instant decadence to anything.
The first time I made this, I just wanted something more fun than plain chocolate sauce—it’s now my party crowd-pleaser. The smell alone always gets everyone hanging out by the stove.
Dreamy Ingredients
- Pinch of salt: Heightens the flavors, sea salt or flaky salt are both great options
- Vanilla extract: Softens the bitter notes and adds cozy aroma, real extract gives the best result
- Cold water: Needed to smooth out the cornstarch—stick with cold to avoid lumps
- Cornstarch: Makes your sauce thick and smooth, so sift it first if needed
- Unsalted butter: Delivers richness and luxe texture, European butter makes it extra silky
- Brown sugar: Gives the sauce a rich caramel taste and nice gloss from the hint of molasses
- Granulated sugar: Brings in sweetness so your sauce balances the coffee, fine sugar melts fast
- Strong brewed coffee or espresso: You want a bold base so brew your favorite dark roast
Easy-To-Follow Steps
- Serve or Store:
- You can use your coffee sauce right now if you’re in the mood for it warm. Or, let it cool and keep in a glass jar in the fridge—it stays good for about a week.
- Finish With Butter and Vanilla:
- Move your pan off the stove, and toss in the butter, vanilla, and a pinch of salt. Stir gently until everything is smooth, glossy, and fully melted together.
- Thicken the Sauce:
- Keep stirring and simmering—the sauce will start to thicken in two or three minutes. It’s good to go when it leaves a shiny layer on the back of your spoon.
- Mix and Add Cornstarch:
- In a different bowl, mix cornstarch with cold water until no lumps remain. Slowly pour this into the simmering sauce, whisking all the while so everything stays smooth.
- Simmer and Reduce:
- Let it bubble softly at medium heat for five to seven minutes, just so it thickens a little and the flavor gets richer.
- Combine Coffee and Sugars:
- Add both sugars and your brewed coffee to a small saucepan. Stir over medium heat until every grain dissolves—keep going till you don’t hear any crunching, and it’s smooth.

I’m here for the brown sugar magic—it gives this sauce shine and a deep, rich vibe. That first time I poured it over pancakes, my kids went wild, trying to sneak spoonfuls straight from the pot!
Keeping It Fresh
Stash in a jar or airtight container in the fridge—it keeps for a full week. If it thickens too much, just warm it gently on the stove or microwave and mix in a splash of warm water 'til it’s runny again.
Other Ways To Make It
Want a new twist? Swap brown sugar for dark maple syrup. Need a dairy-free option? Grab a vegan butter instead. If you’re short on brewed coffee, dissolve a bit of instant espresso in hot water and use that!
Fun Ways To Serve
Try it on vanilla or chocolate ice cream, pour it over waffles, pancakes, French toast, or poke cake. For a grown-up spin, top affogato or pudding with it. I also love filling up tiny jars to surprise coffee-loving friends.
