Step-by-step instructions
Follow these simple steps to prepare, mix, and steam your delicious chocolate jar cakes perfectly.
Step 1: Crack the eggs
Crack one large egg into each of your four clean, heat-safe glass jars. This creates the perfect base for your individual cake servings.
Step 2: Add wet ingredients
Spoon the granulated sugar, vegetable oil, and milk directly into the jars over the eggs. These wet ingredients will help create a moist and tender crumb.
Step 3: Add dry ingredients
Add the all-purpose flour and cocoa powder to each jar, layering them on top of the wet mixture. The cocoa powder provides the deep, rich chocolate flavor.
Step 4: Shake to mix
Securely fasten the metal lids onto the jars and shake them vigorously until the batter is completely smooth. This unique mixing method ensures there are no lumps.
Step 5: Fold in chocolate chips
Remove the lids and spoon a teaspoon of chocolate chips into each jar, stirring them gently with a fork. This adds delightful pockets of melted chocolate throughout.

Step 6: Prepare the water bath
Place the sealed jars into a large pot and pour in water to reach halfway up the sides. The water bath creates gentle steam for even cooking.
Step 7: Steam the cakes
Cover the pot with a tight lid and let the jars steam on the stovetop over medium heat for twenty minutes. The cakes will rise beautifully and set.
Step 8: Drizzle and serve
Carefully remove the hot jars, poke a few small holes in the tops, and drizzle generously with chocolate sauce. Enjoy these warm, fudgy treats straight from the jars.
