Step-by-Step Instructions
Step 1: Melt the butter until it is simmering.

Step 3: Mix the butter and chocolate chips together until it is a smooth mixture.
Step 4: Stir in the sugar, espresso powder, and vanilla extract until combined.
Step 5: In a separate bowl, whisk the eggs until a little frothy.
Step 6: Add the beaten eggs to the chocolate mixture.
Step 7: Combine the eggs and chocolate mixture. The batter will be shiny at this point.
Step 8: Fold in the flour, cocoa powder, baking soda, and salt.
Step 9: Mix until well combined.
Step 10: Prepare a baking pan by adding enough water to come halfway up the sides of the jars.
Quick Tips
- Baking Mason jars in a water bath is generally safe if you ensure the water level is high enough and heat the water gradually.
- Place the jars so they're not touching, and using oven-safe jars adds extra security. This method creates a gentler heating environment, reducing the risk of the jars breaking.
Baking Instructions
Step 11: Fill the jars ¾ way full with brownie batter and sprinkle with coarse sea salt. Set the jars back into the water bath.
Step 12: Carefully transfer the pan to the oven. Bake at 350°F for 30 to 35 minutes.
Step 13: Remove from the oven and allow to cool for 5 minutes. Top with the caramel sauce and another sprinkling of coarse sea salt. Enjoy while still warm!

Not all Mason jars are created equal! Using a regular canning jar in the oven can be dangerous. Always check for the "Oven-Safe" symbol to ensure it can handle the heat.
Prep Ahead Instructions
The brownie batter can be made a day in advance and stored in the refrigerator. Assemble and bake the brownies when ready to serve.
Storage and Reheating Instructions
Refrigerate: Store leftover brownies in the refrigerator for up to 3 days.
Freezer: I do not recommend freezing brownies in Mason jars, especially if they have the caramel sauce already added.
Reheat: Reheat them in the microwave for 15-20 seconds or in a preheated oven at 350°F (175°C) for 5-10 minutes.

Hi,
Can this be served at room temp as well or will it hard enough too much?
Thanks
Lois says
Yes — they can be served at room temperature. They’ll firm up a bit as they cool, but shouldn’t become too hard, and letting them warm up after chilling helps them stay soft and delicious. Thanks for visiting!
Kay says
I appreciate your reply. Thank you.
Lois says
Thank you. Would love to know if you make the recipe and how it turns out for you.

It says; servings; 18.
I actually need 18 ( 4 oz.) jars in order to make this? It's just the 2 of us, so I guess you would make this for a family gathering, pot luck, etc.
Lois says
Hi Colleen! All of my recipe cards include a handy slider that lets you easily adjust the number of servings up or down. You can absolutely scale this recipe down to 2 servings, but I’d recommend making 4—it’s so good, you might want leftovers!
