An Instant Pot Coca-Cola Cake Recipe (with Coke Glaze)

An Instant Pot Coca-Cola Cake Recipe (with Coke Glaze)

It’s been almost five days since I opened my Instant Pot, and I wanted to make a Coca-Cola cake in it.

Although there are plenty of dump cakes, cobblers, and cheesecakes for the Instant Pot, Coca-Cola cake seems to be a relatively uncommon pressure cooker dessert. But it just kind of got into my head, and with my limited experience I went off in search of a recipe for one adapted for the Instant Pot.

How I ended Up With An Instant Pot In The First Place

As an aside, I purchased an 8-qt Instant Pot Duo on Amazon for between $80 and $90. It was an open-box Amazon deal and sort of an impulse purchase based on it being so deeply discounted. As another aside, I established this blog in part to write about cooking (which I love), and it’s been hard for me to be in the kitchen without my husband. He was a complete master there, and we spent a lot of time at the stove.

Keep an eye on the open-box Instant Pot Duos, my 8 qt. (largest size) was cheaper than regular retail for the smallest size. (And it was not used.)

So the Instant Pot serves a little-known ninth function in my case. It lets me cook things that require skill, but spend less time in the kitchen without him there. #justwidowthings

Recipe Details

For this Instant Pot Coca-Cola cake, I adapted a recipe I found on a pressure cooking site. The original recipe can be found here. However, I changed it quite a bit, in ways I normally wouldn’t. Bear in mind I am not a Southerner, and don’t know coke cake traditions from a hole in the wall. Also, I am not opposed to using boxed cake when it suits, such as with a blueberry cobbler recipe that is the best but calls for yellow cake. I buy it by the bushel.

I omitted walnuts because I have kids — picky, picky kids. And I would normally use the chocolate chips, but my daughter requested they be left out. So I compromised and pressed them into the bottom of half. The original recipe used a bundt-springform hybrid, but I decided to go with my IKEA SOCKERKAKA mold ($9.99 for heart shape, round no longer available):

For The Cake

In my version, I used:

  • 10 ounces of Coca-Cola (don’t substitute diet, really);
  • 1 box of chocolate cake mix (pick your favorite);
  • 1/2 c. of chocolate chips (optional but recommended)

That’s it. Do not add anything else to the batter, no eggs or oil. Whisk lightly with a hand whisk and pour into the cake tin or mold of your choosing. Of note is I still have not had my Instant Pot long enough to be betrayed by a non-fitting pan, and I was incredibly lucky that this just fit inside. Whew.

Add one cup of cold water to the instant pot, and place the cake on the trivet. (Part of the reason I ignored my springform 7″ is because I thought it was an unnecessary leak-in-or-out risk.)

Use manual high pressure for 35 minutes. I did a manual release too, and natural release might affect the final outcome. I don’t know, this is my first non-cheesecake in the Instant Pot.

For the glaze

This is something I’ve made in the past, but I haven’t started the glaze yet because the cake is cooling and I plan to do it in the Instant Pot on saute. The cake is a bit smaller than the Texas sheet cake version made from complete scratch, so I will almost certainly halve (half-quantities in brackets) the highly-rated version shared by Genius Kitchen:

  • 1⁄2 c. butter [1/4 c. or half a stick]
  • 1⁄4 c. cocoa [1/8th cup or 2 T.]
  • 1⁄3 c. coca-cola [approximately 3T.]
  • 3 c. powdered sugar [1 1/2 c.]
  • 1⁄2 t. vanilla extract [1/4 t.]

Mix butter, cocoa, and cola until melted/combined in a saucepan or in your Instant Pot. Remove from heat and stir in sugar and vanilla, mixing until smooth. Glaze while frosting is still hot or warm.

How it came out

Honestly, I was even more impressed by this than I thought was possible:

Above is the underside, and when unmolded, it set perfectly into the shape of the bake pan. Whatever size the larger mold is fits perfectly inside the Instant Pot with a trivet. To the right is the chocolate chip side, to the left, plain:

Instant Pot Coca-Cola cake was my first standard baked cake in the device, and by comparison, it makes classic cakes look dry. The batter itself was not glossy and did not promise to be particularly springy, but Instant Pot baking seems to lend an almost-always desirable element of moisture. Unless I was doing tiers, I can’t see opting for the oven over the Instant Pot for cake baking.
