This lemon poke cake brings sunshine to your dessert table with its bright citrus flavor and moist texture that gets better with every bite. The secret lies in poking holes throughout the warm cake, allowing the tangy lemon glaze to seep into every crevice for an irresistible treat that's both simple and impressive.
I first made this cake for my sister's summer birthday when the oven breaking down meant I needed something foolproof. The bright yellow color and refreshing flavor made everyone forget about the fancy layer cake I'd originally planned.
Ingredients
- Box of lemon cake mix: Adds convenience while still delivering great flavor
- Lemon jello: Intensifies the citrus flavor and creates that signature moist texture
- Water: Thins the batter to the perfect consistency
- Vegetable oil: Provides moisture that keeps the cake tender for days
- Eggs: Offer structure and richness to balance the tangy lemon
- Powdered sugar: Creates a smooth glaze without any grittiness
- Butter: In the glaze adds a subtle richness that complements the bright lemon
- Fresh lemon juice: Brings authentic citrus flavor that bottled versions cannot match
Step-by-Step Instructions
- Prepare your baking pan:
- Thoroughly coat a 13x9 inch pan with baking spray. This crucial step ensures your cake releases perfectly after baking. The spray should contain flour too, like Baker's Joy, for best results. Take an extra 30 seconds to ensure complete coverage, including the corners.
- Mix the batter:
- Combine cake mix, lemon jello, water, oil, and eggs in a large bowl. Beat at medium speed for a full 3 minutes until the batter becomes noticeably lighter in color and increases slightly in volume. This extended mixing time incorporates air for a better texture.
- Bake to perfection:
- Pour the batter into your prepared pan and bake at 350°F for metal pans or 325°F for glass. The cake is done when a toothpick inserted in the center comes out clean with no wet batter, approximately 21-26 minutes. The top should spring back when lightly touched.
- Create your poke holes:
- After cooling the cake for exactly 10 minutes, use a fork or toothpick to create holes throughout the entire surface. Space them about an inch apart across the entire cake. These channels allow the glaze to penetrate deeply into the cake.
- Prepare the lemon glaze:
- Whisk powdered sugar in a bowl while gradually adding melted butter and fresh lemon juice. The consistency should be pourable but not watery. Adjust with additional powdered sugar if needed. The glaze should coat the back of a spoon.
- Finish the cake:
- Pour the glaze slowly and evenly across the entire cake, allowing it to sink into the holes. Work from one end to the other, giving the glaze time to absorb before adding more. This patience ensures even distribution throughout the cake.

My favorite part of this recipe is the moment when you pour that glossy glaze over the warm cake and watch it disappear into the tiny holes. It reminds me of childhood summers when my grandmother would make this cake for our family reunions under the maple tree in her backyard.
Make It Your Own
The beauty of this poke cake lies in its adaptability. For a more intense lemon flavor, add a tablespoon of fresh lemon zest to both the cake batter and the glaze. The natural oils in the zest provide aromatic compounds that amplify the citrus profile beyond what extracts can achieve. I discovered this trick after years of trying to get that perfect punch of lemon that reminds me of traditional Italian lemon desserts.
Storage Tips
This cake maintains its moisture remarkably well thanks to the jello and glaze. Store it covered at room temperature for up to two days or refrigerate for up to five days in an airtight container. The flavors actually develop and improve after the first day, making this an excellent make-ahead dessert. For longer storage, freeze the unfrosted cake tightly wrapped for up to three months, then thaw overnight and add fresh glaze before serving.
Serving Suggestions
Transform this simple cake into an elegant dessert by serving slices with a dollop of lightly sweetened whipped cream and fresh berries. For a more decadent presentation, add a scoop of vanilla ice cream and a sprinkle of toasted coconut. During summer gatherings, I like to serve this cake alongside a pitcher of homemade lemonade for a refreshing themed dessert table that always impresses guests without requiring hours in the kitchen.
