💡Did you know?

 The watermelon cake recipe was first found in the 1884 Mrs. Owens’ Cook Book and Useful Household Hints. The recipe is only using red batter and icing. Another legendary story says that Mrs. Rorer showed people how to make this Watermelon Cake at the World’s Fair in Chicago in 1893. Ma says Mrs. Rorer was a famous lady who ran a cooking school and showed people at the fair how to bake. However, we didn’t find any recipe related to this story.

🕐How to make the Watermelon Cake with Betty Crocker Cake Mix

It may take some time to make it as you have to bake the sponge cakes first, then let them cool off completely before put on the colorful icing. In addition, for this recipe, we used watermelon Jello instead of any watermelon or cherry drink. You just need the pink color for the batter.

❓FAQs about the Watermelon Cake with Betty Crocker Cake Mix

Do I have to use the Betty Crocker Cake Mix to make this cake?

No, you don’t have to. This is an adopted recipe from Betty Crocker’s website, so we decided to use their cake mix. For this recipe, we used Betty Crocker Super Moist White Cake Mix. You can make this cake like any other sponge cake really. Check the recipe for a sponge cake here

Can I use a soft drink mix instead of Jello?

You can use a soft drink mix instead of any red colored Jello. As long as the drink mix is red colored is fine. Ideally, the drink and/or the Jello should be unsweetened. This cake has a lot of frosting, so it is super sweet

How can I make Jello?

The instructions are on the box. But find them here: You need 2 cups boiling water and 2 cups cold water. Add boiling water to gelatin mix; stir 2 minutes until completely dissolved. Stir in cold water. For this recipe, you only need 4 tablespoons from the mix. Refrigerate the remaining liquid for 4 hours or until firm. Your Jello is ready. Serve in cups with fruit

Can I make the Watermelon Cake gluten free?

You can make this cake gluten free using gluten-free flour. As always, changing the flour will change the consistency of the dough and, therefore, the recipe may well need to be tweaked. Substitute one cup of all-purpose flour with one cup of gluten free flour. You may need to add some stabilizers such as xanthan gum. Follow the recipe for a sponge cake

How can I serve this Watermelon Cake?

Serve the cake at room temperature cut in slices. You can cut thin slices or thick slices, it’s up to you

How can I store the Watermelon Cake?

I personally do not like to keep cakes with frosting at room temperature for a long period even if they are stored in an airtight container – no more than a day. You can keep the Watermelon Cake in the fridge for up to 3 days covered with a plastic wrap. You can keep it longer if you wish, but the cake will not be as fresh. Keeping it in the freezer sliced in ziplock bags is also a possibility but no more than 3 months. Always remove cake from the freezer and let it reach room temperature before serving
