Baking a cake can be so much fun. My kids and I love to set up all of our supplies and spend the weekend creating something beautiful. The Hershey Bar Cake and our Chocolate Cheesecake Cake are two of our most favorites.

I think this would make such a great treat for a summer BBQ or a birthday party.

This watermelon cake doesn’t just look like a watermelon, it tastes like it, too. Want the secret? It’s watermelon flavored Jello!

To create the vibrant watermelon coloring, you’ll want to mix two colors of dye together: red and neon pink. It works perfectly to make your cake look like a watermelon. You’ll also use the same coloring to make the icing that goes in between each layer.

The Best Cake Baking Tips

  1. It is always best for your cold ingredients (butter, eggs, milk, etc) to be at room temperature. Try to set them out for a bit before starting your cake.
  2. Scoop your flour out gently without packing it – if not you’ll end up with too much flour.
  3. To keep your chocolate chips from sinking to the bottom of the cake batter, coat them in flour first.
  4. Don’t put your cake in the oven before it’s done preheating.
  5. Always try and use real vanilla extract, not imitation –  the flavoring is so much better! To find the right vanilla, just look for the word “pure” on the bottle.

Following just a few simple tips will make your cake come out perfect every time.
