This Pistachio Pudding Poke Cake is a sugar-free made from scratch cake that is a retro recipe from the 70's. It is a birthday cake favorite and, because of the green color, it makes a great dessert to serve on St. Patrick's Day.
Traditionally, this pistachio cake recipe is made with a white or yellow cake mix that is baked and cooled, then you poke holes all over the top of the cake before pouring the instant pudding over top. The cake holes fill with the pudding while a layer of pudding remains on top, then it is covered with cool whip for a deliciously moist cake the whole family will love.

For the cake
- Pre-heat the oven to 350°F. Spray an 8 x 8 cake pan with cooking spray, set aside.
- Lightly spoon the flour into a dry measuring cup and level with a knife and place the flour in a medium bowl. Add the potato starch, salt, and baking powder, stirring to combine with a whisk.
- In another mixing bowl, combine the sugar free sweetener and coconut oil, beating with an electric mixer at low speed until blended. Mixture will be like damp sand.
- Whisk the egg yolk to the sugar mixture and mix until throughly combined. Add the egg white, and mix until combined.
- Add the coconut extract into the measured almond milk.
- Combine the flour mixture and almond milk mixture alternately to the egg mixture, beginning and ending with the flour mixture.
- Pour the cake batter into the prepared pan and bake for 20 minutes or until the cake springs back when touched lightly in the center. Cool completely on a wire rack.
For the Topping
- Once cake has cooled, poke holes in cake about 1" apart using the handle of a wooden spoon. Set aside.
- Make the pistachio pudding mix per the package directions. When thickened but still pourable, pour the pudding mix over top of the cake, spreading it out to fill up the holes. Let sit in refrigerator for 2 hours until cold and pudding has set.
- Remove the cake from the fridge and spread with the sugar free cool whip topping.
Wooden spoon with rounded handle
This pistachio cake recipe is best kept refrigerated for up to 4 days.
- Bake the cake in a bundt pan and load the center with pistachio ice cream before adding the whipped topping for delicious homemade pistachio ice cream cake!
- Change this poke cake up by using different pudding mixes, like chocolate or vanilla pudding!
- Make this pistachio pudding favorite a layer cake by doubling the recipe and adding cream cheese frosting tinted with green coloring in between the cake layers!
💭 Top Tips
- Make sure you don't use unsweetened almond milk in place of the milk for the pistachio pudding mix. If you do, the pudding will not set.
- A box mix can be used in place of the homemade cake mix in this pistachio poke cake recipe.
Yes, and because of the cool whip and pudding this poke cake shouldn't be left at room temperature for more than 4 hours.
The holes allow pudding to disperse throughout the poke cake resulting in moist, pistachio flavor in every bite.
A wooden spoon with a rounded handle works best. Use the tip of the rounded end to poke holes into the cake.

Hi Shelby, I don't know what happened to my comment, I love your recipe and I'm almost sure I left a comment yesterday. I liked the changes you made to the recipe to make it fit your new dietary changes. I have also been making changes this past year to many of my recipes also. Once you get the hang of it it's easy and the results are amazing. Thanks for sharing your recipe, and since I've never made a poke cake, I will definitely give this a try.
I love that you made your cake from scratch, I'm not too keen on boxed mixes either. The cake looks fantastic.
I love this idea. I've never made poke cake with pudding, but yours looks so decadent, yet it's not!
Renee, you really need to sometimes. 🙂 Mom used to make them all the time, they became popular when I was a teenager and I loved them. She also would make the frosting with cool whip and pudding like Meghan did for her recipe.
How perfect for St. Patty's Day. That pistachio flavor must be simply lovely. BTW, I had your blog this month and made your scones, sooo good.
Lisa, I saw your post! I think you did an awesome job and I love the cranberry lime twist!
