What You’ll Need (Ingredients)

For the cake:
- 1 box lemon cake mix (15.25 oz)
- 3 large eggs
- 1/2 cup neutral oil (canola or vegetable)
- 1 cup milk (whole or 2% for richer crumb)
- Zest of 1 large lemon
For the lemon soak (poke syrup):
- 1/2 cup fresh lemon juice (about 3–4 lemons)
- 1/3 cup granulated sugar
- 1/4 cup water
- Pinch of salt
For the topping:
- 1 cup heavy whipping cream, cold
- 4 oz cream cheese, softened
- 1/3 cup powdered sugar (plus more to taste)
- 1 teaspoon vanilla extract
- Optional: 1 tablespoon lemon zest for garnish
Optional extras:
- 1/2 cup lemon curd (warmed slightly for spreading)
- Fresh berries for serving

Step-by-Step Instructions

Preheat and prep: Heat oven to 350°F (175°C).
Grease a 9×13-inch pan or line with parchment for easy lift-out.
Mix the cake: In a large bowl, whisk cake mix, eggs, oil, milk, and lemon zest until smooth, about 1–2 minutes. Don’t overmix—just no dry pockets.
Bake: Pour batter into the pan and bake 23–28 minutes, until the center springs back and a toothpick comes out clean. It should be lightly golden.
Make the lemon soak: While the cake bakes, combine lemon juice, sugar, water, and a pinch of salt in a small saucepan.
Warm over low heat, stirring until sugar dissolves. Remove from heat and let it cool to lukewarm.
Poke while warm: Let the cake rest 5–10 minutes, then poke holes evenly all over using the handle of a wooden spoon or a thick skewer. Go almost to the bottom but don’t pierce the pan.
Soak it: Slowly spoon or pour the lemon syrup over the cake, letting it seep into the holes.
Expect some pooling; it will absorb as the cake cools.
Optional curd layer: If using lemon curd, warm it slightly to loosen, then spread a thin layer over the cooled, soaked cake. This is the “oh wow” layer.
Whip the topping: Beat cream cheese until smooth. Add powdered sugar and vanilla; beat until fluffy.
In a separate bowl, whip the cold cream to medium peaks. Fold the whipped cream into the cream cheese mixture until silky.
Frost and chill: Spread the whipped topping over the cake. Sprinkle with extra lemon zest if you’re feeling fancy.
Chill at least 2 hours (overnight is elite) so flavors marry.
Serve: Slice into squares. Add berries if you want bonus points. Try not to eat three pieces.
Or do—your call.

Storage Tips

Refrigerate: Cover and store in the fridge for up to 4 days. The texture stays moist and the lemon flavor deepens.
Make-ahead: Bake and soak the cake a day ahead; add the topping the morning of serving for best structure.
Freezer: Freeze the soaked, unfrosted cake (well wrapped) for up to 2 months. Thaw in the fridge and add topping fresh.

Nutritional Perks

Portion control-friendly: It’s rich, so a small square satisfies the sweet tooth without a sugar avalanche.
Vitamin C cameo: Fresh lemon juice and zest bring a bit of C and a lot of flavor—win-win.
Lower-fat topping option: Swap cream cheese for Greek yogurt for a tangy, lighter crown (details in Variations).

Pitfalls to Watch Out For

Under-poking: Too few holes = dry pockets.
Make a grid pattern about 1 inch apart for even soaking.
Over-mixing the batter: This can make the cake tough. Stop as soon as it’s smooth.
Pouring hot syrup on a hot cake: If both are piping hot, it can make the crumb gummy. Aim for warm cake, lukewarm syrup.
Runny topping: Warm cream or overbeating can deflate it.
Use cold cream and fold gently.
Skipping chill time: I get it—you’re hungry. But chilling sets the layers and makes clean slices. Patience pays.

Recipe Variations

Lemon-Blueberry Poke Cake: Fold 1 cup fresh blueberries (tossed in 1 tablespoon flour) into the batter.
Add an extra 5 minutes of bake time if needed.
Greek Yogurt Frosting: Replace cream cheese with 1 cup thick Greek yogurt and reduce powdered sugar to 1/4 cup. Tangy, lighter, still lush.
Limoncello Soak (Adults Only): Swap 2–3 tablespoons of the water with limoncello. FYI: boozy but subtle.
Meyer Lemon Upgrade: Use Meyer lemons for a sweeter, floral vibe.
Reduce sugar in the soak by a tablespoon to balance.
Sheet-to-Layer Glow-Up: Bake in two 8-inch rounds, poke and soak each, then stack with lemon curd between layers. Dramatic? Yes.
Difficult? Not really.
Glaze Instead of Whip: Whisk 1 cup powdered sugar with 2–3 tablespoons lemon juice and 1 tablespoon melted butter. Pour over cooled, soaked cake for a shiny finish.

FAQ

Can I use a white or yellow cake mix instead of lemon?

Yes.

Add 2 teaspoons lemon extract and the zest of 1–2 lemons to the batter to boost the citrus flavor. The lemon soak will still make it taste bright and lemony.

Do I have to use fresh lemon juice?

Fresh is best for flavor and aroma. Bottled works in a pinch, but reduce sugar in the soak slightly if the bottled juice tastes sharper.

How do I prevent the cake from getting soggy?

Don’t over-saturate.

Poke evenly, pour the syrup slowly, and let it absorb before adding more. Also, ensure the syrup is lukewarm, not hot.

Can I make this gluten-free?

Use a gluten-free lemon cake mix and verify all other ingredients are GF. Texture stays tender because the soak keeps it moist.

What if I don’t have cream cheese for the topping?

Use all whipped cream stabilized with 1 tablespoon instant pudding mix or 1 teaspoon unflavored gelatin bloomed in 1 tablespoon water.

It helps the topping hold up.

How long should I chill the cake before serving?

At least 2 hours, but 6–8 hours is ideal. Overnight gives the most cohesive, bakery-style slice.

Can I reduce the sweetness?

Cut the soak sugar to 1/4 cup and use the Greek yogurt frosting variation. You’ll keep the tang without the sugar bomb.

What’s the best tool for poking holes?

The handle of a wooden spoon makes ideal, even holes.

A thick skewer works too; just poke more frequently for good coverage.

The Bottom Line

This lemon poke cake recipe delivers the trifecta: easy, impressive, and wildly flavorful. The lemon syrup guarantees moisture, the topping adds creamy lift, and the whole thing tastes like sunshine in cake form. Make it once for a crowd, and you’ll get “Wait, you made this?” texts forever.

Low effort, high payoff—exactly how dessert should be.
