Jello Lemon Bars

Jello Lemon Bars

My husband husband and I are living with my Grandparents right now while we wait to move across the country for his residency in Indiana . It has been so fun being here.  Living with someone lets you see a whole other side of them that you usually don’t see.  We have LOVED being here and will be sad to go!  One thing that I will miss is my Grandma’s cooking!  She made these Jello Lemon Bars and they were so good, I just had to make them again!  If you love lemon, you are going to LOVE these!


Jello Lemon Bars
serves 12



1 package of yellow cake mix

1 (3 ounce) dry package of lemon Jell-O gelatin

4 eggs

3/4 cup water

3/4 cup vegetable oil



2 cups of powdered sugar

2 lemons, juiced (about 6 tablespoons)

2 tablespoons of melted butter



Preheat your oven to 350 degrees.

Mix together the cake mix, jello, eggs, water and oil. Make sure it is mixed well.

Spray a 9×13 glass pan with non-stick spray and pour your batter into it.

Bake for 35 to 40 minutes or until a toothpick comes out clean.

Mix together your butter, powdered sugar and lemon juice.

When your cake is done cooking, poke holes all over the cake. (I used the back of my wooden spoon)

Pour the frosting over the cake while it is still hot from the oven. That way the frosting will seep into the cake.

You can serve it warm or cold.

    My family lives in Muncie. I am assuming your husband will be at IU Health Ball Memorial Hospital. My husband is a volunteer there two days a week and we know several people associated with the hospital. I will be happy to help you with anything you need before or when you come to Muncie. We have lived here all of our married lives which is coming up on 46 years. Feel free to contact me if you need something.
    • Thank you so much June! We are so excited to move there! IU Ball Memorial was our first choice - the main reason being the people my husband met out there! I will be sure to contact you if I have any questions! Thanks again!
  2. I have tried this recipe twice in a glass 9x13 cake pan. It never rises as much in the center as it does the sides. Any ideas of what I am doing wrong?? It still tastes very yummy, just doesn't look like the picture.
  3. I have been making this recipe for 45 years using lemon cake mix. It's a family favorite birthday cake. The cake sinks in the middle creating the most scrumptious lemony gooey pieces. If you leave the pan in the oven another 2 minutes the center doesn't sink in the middle. Also I use a fork to poke holes in the top of the cake so that the glaze is more evenly distributed. But mine never came out looking like the bars pictured above but more of a cake appearance and texture. FYI: try mixing it up a little, orange cake mix with orange jello, strawberry cake mix with strawberry jello, even tried the blueberry cake mix and berry jello. For the glaze I still use the powdered sugar and water leaving out the lemon juice subsituting with fruit juice/orange juice,

    Thank you so much for this super simple and delicious recipe! My husband hates cake but LOVES lemon bars so I decided to surprise him and try this out for his birthday. He's very picky and loves his bars extra tart so I added an extra lemon, he absolutely loved it. This will definitely be his "birthday cake" from now on :-)

    I made this and like everyone else, got a fluffy, thick, moist cake. I'm wondering if it should be 4 egg yolks and not whole eggs as the whites would add to the fluffiness and the yolks would tend to make it dense. Either way, it's delicious!
  6. I’m printing this out as I type! This sounds delicious 😋. I’m diabetic so I’d use a sugar free cake mix, sugar free jello, and Splenda for the icing. I adapt recipes all the time and will be launching a website soon. I’ll be sure to credit you with a link when I post this.
