How to Make Cake in a Jar Recipe
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures your cake bakes evenly.

In a mixing bowl, combine:
1. All-purpose flour

4. Baking powder
Stir these dry ingredients until well blended.

Step 7: Fold in Sprinkles
Gently fold in rainbow sprinkles for added color and fun!
Step 8: Fill Jars
Spoon batter into prepared mason jars, filling them about halfway full to allow room for rising.
Step 9: Bake
Place filled jars on a baking sheet and bake for about 15 minutes or until a toothpick inserted into the center comes out clean.
Step 10: Cool Down
Remove jars from the oven and let them cool completely before frosting.

Common Mistakes to Avoid
When making your Cake in a Jar Recipe, avoid these common pitfalls for the best results.
Not measuring ingredients correctly: Always use precise measurements to ensure your cake has the right texture and flavor. Use measuring cups and spoons designed for baking.

Overmixing the batter: Mixing too much can make your cake dense. Mix until just combined to keep it light and fluffy.
Neglecting to preheat the oven: If the oven isn’t hot enough, your cake may not rise properly. Preheat it for at least 15 minutes before baking.
Ignoring baking times: Each oven is different, so start checking your cake a few minutes before the suggested time. This helps prevent overbaking.
