I am so excited to bring you this Instant Pot cake recipe. The first in my series of Mini Cakes created, especially for the Instant Pot. I spent several days perfecting cakes and testing out different flavors and the results were delicious!

Perfect Lemony Goodness

I’ve been wanting to make a cake in the Instant Pot using a boxed cake mix. I knew cakes could be successful in the Instant Pot since my Turtle Lava Cakes are to die for! I love baking, and I really wanted to start using my Instant Pot for a few more “baked goods”.

I wanted it to be easy and require minimal ingredients. Kind of like a mini sweet treat for when that craving hits (which seems to be often).

Since it’s summertime, I was determined to make my first mini cake a fresh summery flavor. So I put together a few ingredients and what I got was a deliciously moist, perfect Lemon Mini Cake!

A Perfect Summer Treat

I spent a few days coming up with flavors for my mini cake series, which meant we got to eat a lot of cake! No one seemed to have a problem with it! I even took out mini slices to my neighbors and their kids one afternoon while they were all gathered outside playing.

Everyone loved the cakes and they all had different opinions about which was their favorite. As for my family, the majority said lemon was tops! I know your family will love it too!

Kitchen Prep Tools, Utensils & Appliances

Before we get started, here is a list of the kitchen prep tools, utensils, and appliances I used to make this recipe.

Prep Tools & Utensils

These are the items you’ll need to prep and make this recipe:

  • For prepping the cake batter, I used one of these colorful prep bowls, these beautiful measuring spoons, and some measuring cups.
  • This recipe requires lemon juice for making the glaze. I don’t like hand squeezing lemons because 1. it can get messy, 2. after a few lemons my hands start to cramp, and 3. I’m only able to get half of the juice out of the lemon. I always use a lemon squeezer to make sure I can get every drop out of each lemon. Plus, it’s so much easier on my hands.
  • I always make sure to use a good cutting board when cutting lemon because the acid from the lemon juice always ends up staining my countertops. Definitely, want to avoid that.
  • To top off the cake, you can lightly zest a lemon. A good lemon zester is one of those kitchen utensils that you won’t use often but is essential to have around.
  • I set the cake pan on the trivet before lowering it into the pot. Once the cooking time had completed, I used my mini mitts to lift the trivet out of the hot pot.
Appliances & Cookware

I made this mini cake in my 8 quart Instant Pot using a small bundt pan that I picked up at Aldi – this one should work fine as well. I’ve also made it in a 6″ x 2″ cake pan. It’s not as pretty but gets the job done.

Serving Platters & Dishes

I served this cake on my pretty aqua plates.

Once the cook time has completed, allow for a 15 minute NPR (natural pressure release).

7

After the pressure has been released and the pin has dropped, open the pot and carefully remove the cake from the pot.

8

Remove the foil from the cake pan, then place the cake on a cooling rack and allow the cake to cool.

Tips & Tricks

Here are a few tips & tricks to help you make this Lemon Cake your own:

  • Add lemon zest. I don’t usually go this extra step because the cake is super delicious as it is but if I’m having a get-together with friends, I’ll pull out the lemon zester to dress the cake up a bit.
  • Replace the glaze with frosting. What’s better than a glaze? Cream cheese frosting!
  • Experiment with flavors. This recipe calls for a lemon flavored cake mix and lemon pie filling, but be adventurous and try other flavors of cake mix and pie filling. As long as you use the same measurements, your cake will come out great.

Serving Suggestions

Here are a few ideas for serving your Lemon Cake:

  • Add ice cream. This lemon cake goes great with a scoop of vanilla ice cream or raspberry sorbet.
  • Serve with tea. Lemon cake is a great reason to invite some friends over for an afternoon tea.

How to Make Lemon Cake in the Instant Pot

This is a super simple recipe – the cake itself only requires 3 ingredients.

Gather your Ingredients

For the cake, you will only need a box of Duncan Hines Signature Lemon Supreme Cake Mix, an egg, and some lemon pie filling. That’s it!

I used a lemon fruit filling that I picked up at my local Kroger grocery store – any lemon fruit filling will work. You can also make your own lemon curd, or use store-bought lemon curd.

Preparing the Cake Batter

Just place the dry cake mix, fruit filling, and egg in a mixing bowl and mix by hand with a spoon or spatula until all the ingredient are fully mixed. However, be careful not to over mix –  do not mix the batter until smooth. You want the batter to remain somewhat lumpy before pouring it into the cake pan. Avoid using a whisk and definitely, do not use a handheld mixer. Over mixing could cause the cake to not rise and turn out like a custard. If your cake does not rise and ends up having a thick, custardy consistency then it is likely that the batter was over mixed.

Add the Batter to the Cake Pan

Spray a small cake pan with cooking oil and then pour the batter into the pan.

I used a small bundt pan that I found at Aldi. If you don’t have an Aldi nearby and are unable to find a similar bundt pan then this one should work.

I have also used a small 6″ x 2″ cake pan and it worked perfectly. The bundt pan makes a prettier cake though 🙂

Wrap and Cook

Tightly wrap the cake pan with aluminum foil before placing it into the Instant Pot.

Add two cups of water to the Instant Pot and then place the cake pan on the trivet and lower into the pot.

I suggest that you always use a separate sealing ring when cooking cakes and desserts in your Instant Pot. You don’t want your sweet treats smelling and tasting like garlic or curry powder.

Set the Instant Pot to cook on ‘Manual’ or ‘Pressure Cook’, High Pressure for 40 minutes.

Once the cooking time has completed, allow for a 15-minute natural pressure release.

Once the NPR has completed, remove the cake from the pot and set it on a cooling rack to cool.

Making the Glaze

For the glaze, you will need to sift ½ a cup of confectioners sugar.

You’ll also need one tablespoon of freshly squeezed lemon juice.

Add the lemon juice to the sugar and begin mixing. Continue mixing until the sugar fully dissolves into the lemon juice.

At first, it’s going to seem like the lemon juice is not enough but don’t worry. As you continue stirring, the sugar will be fully dissolved and create a nice glaze.

Add the Glaze to the Cake

While the cake is still sitting on the cooling rack, slowly pour the glaze over the cake until it is fully covered.
