This was soooo much fun to make. When my husband came home from work and noticed it on the counter his first reaction was WOW! He probably thinks it took me hours to make this. Truth is, it took no time at all. Today I am sharing a Christmas wreath cake with cranberry lime seltzer in the Instant Pot.

Lite And Fluffy

I cut out A LOT of calories in this cake as well by adding a cranberry lime seltzer with zero calories in lieu of the oil, eggs, and water. Feel free to use any flavor to your own liking. The brand I used was Polar.  You read that right, this cake was made with seltzer only. YAHOO! I used fresh fruit such as strawberries, blueberries, and black raspberries for the topping and skipped the frosting.  I will mention this tip: If I had frosted the cake I could have packed on more fruit and it would have sat nicer on the cake. Instead, I used green gel icing instead and tried my best to keep the fruit on the cake. It worked out overall but I know frosting would have worked better. Again, I am trying to cut calories any way I can and have a sweet tooth that I have no control over. I need a cake!

This little deer head I found at the Dollar Tree and just set him on the end and the antlers sat nicely in the middle of the cake.

I made my cake in my two-in-one Bundt pan, of course.

I let it cool for 10-15 minutes before I released the springform. Let the cake cool for about 20-30 minutes more before I flipped it over to the pretty side.  

How cute would this be for the holidays? Pretty cute right. 🙂 It not only was cute, but it also tasted so good and moist. I am very happy with how the soda cake worked out in the Instant Pot.

Zero Skill Required

Give it try! This cake and decorating require ZERO skills, my friend. If I can do it, you can do it. I am not going to calculate the Weight Watcher points on this one but I will leave you with the box info. I would assume it should be calculated with the box mix only. Seltzer has 0 calories and 0 sugar.

Two ingredient soda cake in the Instant Pot


  • 1 box Duncan Hines White cake mix I used French Vanilla
  • 12 oz. Flavored seltzer soda


  • Mix by hand the cake with the 12 oz. of seltzer soda. You can use any soda flavor you like and it does not have to be seltzer soda.
  • Lightly spray bundt pan with non-stick cooking spray. Add one cup of water to the Pressure Cooker. Set pan on a trivet with handles for ease of getting in and out of pot.
  • Lower pan in the pot and set to high pressure manual for 35 minutes. Quick release and let cake cool. Frost or decorate to you liking. This was a perfect holiday wreath cake.

Enjoy! Pin it, make it.
