Nothing brightens chilly days like the zingy sweetness of this lemon cake with syrupy glaze. It is soft tangy and quick to make making it the ultimate treat for breakfast dessert or any festive gathering. I always bake it when my sister visits for the holidays and now it has become the centerpiece of our winter table.
Every time I make this cake the whole house smells like sunshine and my family cannot wait to dig in when the glaze sets.
Ingredients
- Yellow cake mix: This is the foundation of your cake delivering consistent results and saving time. Choose a reputable brand for best texture.
- Instant lemon pudding mix: Intensifies the lemon flavor and creates a soft tender crumb. Check the package for bright yellow color and strong lemon aroma.
- Water: Ensures the batter is light and evenly blended. Use filtered water for clean taste.
- Oil: Makes the cake extra moist. Choose a neutral oil such as sunflower or canola.
- Eggs: Bind everything together and help the cake rise. Look for fresh eggs with unbroken shells for fluffiest results.
- Powdered sugar: The base for the syrup providing that classic smooth sweetness. Sift before using for the silkiest glaze.
- Lemon juice: Adds fresh tanginess to glaze. Juice real lemons for brighter flavor rather than bottled.
- Unsalted butter: Enriches the glaze with luxurious mouthfeel. Use real high-quality butter for the best results.
Step-by-Step Instructions
- Prepare the Pan and Oven:
- Preheat your oven to 350 degrees Fahrenheit and grease a 9 by 13 inch baking pan thoroughly to prevent sticking. Take your time smoothing butter into corners for a fuss-free release.
- Mix the Wet Ingredients:
- In a large mixing bowl crack the eggs. Beat them using an electric mixer on medium until light and foamy. This step gives the cake its signature soft crumb.
- Blend Cake Mix and Pudding:
- Add the yellow cake mix instant lemon pudding mix water and oil. Blend on low speed first to avoid splashing then gradually increase to medium speed. Continue mixing until the batter is silky and consistent with no lumps left. Scrape down the sides once or twice.
- Bake the Cake:
- Pour the batter evenly into your prepared baking pan smoothing the surface with a spatula. Place into the oven on the middle rack. Bake for 30 to 35 minutes. A toothpick inserted in the middle should come out clean and the cake will lightly spring back when touched.
- Prepare the Lemon Syrup:
- While the cake bakes melt the butter and combine with lemon juice water and powdered sugar in a mixing bowl. Stir until completely smooth. The syrup should be pourable and glossy with a balanced sweet-tart taste.
- Soak and Cool the Cake:
- When the cake is freshly baked poke holes all over it using a skewer or fork. Pour the syrup slowly and evenly over the warm surface making sure it seeps into the holes. Leave the cake to cool fully in the pan so the syrup sets and the flavor develops.

My favorite part is the syrup soaking step. It reminds me of being a kid poking the warm cake with my sister while waiting impatiently for our first slice. The lemon aroma always made us grin before even tasting.
Storage Tips
Cover leftover cake tightly and store at room temperature for up to two days or in the fridge up to five days. The syrup keeps every slice fresh and delicious. Slices freeze well if wrapped in cling film and stored in an airtight container. Thaw in the fridge or gently warm in the microwave.
Ingredient Substitutions
If you cannot find lemon pudding mix opt for vanilla pudding and add extra lemon zest or juice to the batter. Substitute yellow cake mix with white cake mix for an equally tender crumb. Olive oil provides a slightly deeper flavor if that is all you have on hand.
Serving Suggestions
Serve chilled or at room temperature. For brunch garnish slices with fresh berries and a dusting of powdered sugar. Whipped cream or a scoop of vanilla ice cream makes it extra festive for dessert. This cake shines on holiday mornings with hot tea or coffee.

A Bit of Cake History
This recipe takes inspiration from classic American poke cakes popular since the 1970s when boxed cake mix and instant pudding became beloved kitchen shortcuts. The soaking syrup technique ensures every crumb is packed with bright flavor and keeps traditions alive for modern families.
