Lemon Jell-O Cake is a bright and zesty dessert made with lemon-flavored gelatin that’s mixed right into the batter, creating an ultra-moist, tender crumb. The cake is often finished with a sweet-tart lemon glaze poured over while still warm, allowing it to soak in for extra flavor. Its vibrant color and bold citrus taste make it a refreshing treat for spring and summer gatherings. Easy to make and irresistibly tangy, it’s a crowd-pleaser that never goes out of style.

Ingredients

• 1 box yellow cake mix

• 1 (3 oz) box lemon Jell-O gelatin mix (not pudding)

• ¾ cup water

• ¾ cup vegetable oil

• 4 large eggs

• 2 cups powdered sugar

• ¼ cup fresh lemon juice

• 1 tbsp lemon zest (optional)

Directions

• Preheat oven to 350°F (175°C). Grease a 9×13-inch baking pan.
• In a large bowl, combine cake mix and lemon Jell-O powder.
• Add water, oil, and eggs. Beat on medium speed for 2 minutes, until smooth and slightly fluffy.
• Pour batter into prepared pan and smooth the top.
• Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
• While the cake is baking, whisk together powdered sugar, lemon juice, and zest to make the glaze.
• Remove cake from oven. While still hot, poke holes all over the top with a fork or skewer.
• Pour glaze evenly over the warm cake, letting it soak in.
• Cool completely before slicing and serving.
