HOW TO MAKE LEMON BLUEBERRY POKE CAKE:
Prepare the lemon cake according to the package directions for a 9×13 baking dish.

While cake is baking, prepare the blueberry lemon sauce. In a medium saucepan, add blueberries, lemon zest, lemon juice, sugar, cornstarch, and salt. Stir to combine. Cook over medium heat, stirring occasionally, until the mixture starts to bubble and thicken. Remove from heat and stir in the vanilla. Set aside.

Remove the cake from the oven and allow it to cool for 5 minutes. Use the handle of a wooden spoon to poke holes into the cake that are about an inch apart.

While the cake is still warm, drizzle the blueberry lemon sauce on top. Spread the sauce into an even layer over the cake ensuring some of the sauce and blueberries get down into the holes. Let the cake cool completely (about an hour.)

In a large bowl, whisk together the the lemon curd and the whipped topping until smooth. Spread the whipped lemon topping on top of the cake into an even layer. Place the cake in the refrigerator for at least 1 hour before serving.

Love love this cake!! Super easy to make. It was a big hit for my party unfortunately I kept it all to myself and no one got any to go lol
LOL! Good thinking on your part, Paula!!
Oh my goodness!!! This is my new favorite cake. It’s easy to make and absolutely scrumptious.
How far in advance can I make this before it gets soggy?
I would say no more than a day ahead of time. It does get better as it sits overnight in the fridge 🙂
I plan to make this as soon as the gluten-free lemon cake mix arrives! It looks so good! Thank you for posting it!
OMG this sounds divine! Love blueberries & lemon anything! Will be trying soon and let you know how much we loved it…. 😉 Thanks for all your recipes.
This cake is super easy to make. It came out moist and delicious. Nothing better than lemon and blueberries. If my picky husband liked it, it has to be great.
Looks great
I love poke cakes and made them a lot when my kids were growing up. Now, with kids grown and gone and my metabolism slowing down (Ugh!) I have to count calories. I’d enjoy making two 8×8 pans of this recipe and freezing one for later use so I don’t get tempted to overdo it. Do you think it’s freezable? I was thinking of making the cake, poking holes, spreading blueberry topping and making a 1/2 recipe of frosting for the first 8×8, freezing the second 8×8 for the future and making the second half of the frosting when I’m ready to thaw and use the second 8×8 poke cake. Would freezing it ruin it? What do you think?
I finally fixed this recipe yesterday. It is so delicious! My husband loves blueberries and I love lemons so it was a match made in heaven! I’m going to make it again and take it to work to share with my co-workers. I know it will be a hit with them.
Made for our desert for memorial day. Was a huge hit! Perfectly sweet and sour light and fluffy! I’ll be making it again! Turned out awesome!
OMG I LOVE lemon! This cake is DIVINE!!
YUM! This cake look so good! I love blueberry and lemon together – delicious ♥
