How to Make Cake in a Jar Recipe
Step 1: Prepare Your Jars and Oven
Start by preheating your oven to 350°F (175°C). Lightly grease the inside of each mason jar with cooking spray or butter to prevent sticking and ensure your cakes release easily after baking. This simple step guarantees a perfect texture and an effortless eating experience.
Step 2: Mix the Batter
In a large bowl, combine the cake mix, water, vegetable oil, and eggs. Follow the instructions on the cake mix box carefully to blend everything into a smooth batter. This mixture will form the heart of your jars and is surprisingly easy to prepare—don’t rush this step, as a well-mixed batter produces the best cakes!
Step 3: Fill the Jars
Pour the batter evenly into each jar, filling them only halfway. Leaving space for the cake to rise during baking is crucial because it prevents overflow and maintains an appealing shape. Plus, the visual layering later on looks fantastic!
Step 4: Bake and Test
Place the filled jars on a baking sheet for stability and bake for 25 to 30 minutes. To check if your cakes are done, insert a toothpick into the center; if it comes out clean, your cakes are perfectly baked. This method ensures moist yet fully-cooked cakes every time.
Step 5: Cool Completely
Once out of the oven, let the cakes cool thoroughly inside the jars. Cooling is key to prevent the frosting from melting and keeps your cake intact. This is when patience pays off for the best presentation and taste.
Step 6: Add the Frosting
Top each cooled jar cake with your chosen frosting. You can pipe it elegantly with a piping bag for a neat finish or spread it casually with a spoon for a charming, homemade look. For a stunning twist, layer frosting and cake alternately inside the jar, creating an eye-catching dessert ready to impress.
Step 7: Seal and Serve
Seal each jar with its lid to keep the cake fresh. These sealed jars make serving a breeze and are perfect for gift-giving, picnics, or simply enjoying a personalized treat wherever you go.
