No oil or butter needed
Incredibly moist and fluffy
Perfect for beginners

It’s the kind of recipe that feels almost too simple to work — but it absolutely does.

The 3 Main Ingredients

Here’s what you’ll need:

1 box lemon cake mix (about 15–16 oz)
1 (15 oz) can lemon pie filling
3 large eggs

That’s it. No oil. No extra water. No mixer required (though you can use one if you prefer).

Optional (But Recommended) Frosting

While technically optional, a light frosting makes this cake feel bakery-worthy. Try:

Light Cream Cheese Frosting

8 oz light cream cheese (softened)
1–1½ cups powdered sugar (adjust to taste)
1 tsp vanilla extract
1–2 tbsp milk (if needed for consistency)

Or keep it extra light with:

Light whipped topping
Greek yogurt + powdered sugar + lemon zest
Simple lemon glaze (powdered sugar + lemon juice)

Step-By-Step Instructions

Step 1: Preheat & Prepare

Preheat your oven to 350°F (175°C).

Grease a 9×5 loaf pan or 9×9 baking dish with:

Nonstick spray, or
Light butter, or
Parchment paper for easy removal

If using a loaf pan (like the one in your image), expect a taller, bakery-style cake.

Step 2: Mix the Batter

In a large mixing bowl:

Add the cake mix.
Add the entire can of lemon pie filling.
Crack in the 3 eggs.

Stir until fully combined.

At first, it may look thick or slightly lumpy — keep mixing gently. You want everything fully incorporated but don’t overmix. Once smooth and thick, you’re done.

Beginner Tip:
If mixing by hand, use a sturdy spatula and fold from bottom to top. If using a mixer, mix on medium speed for about 1–2 minutes.

Step 3: Pour & Smooth

Pour the batter into your prepared pan.

Smooth the top with a spatula so it bakes evenly.

Step 4: Bake

Bake for 35–45 minutes, depending on your pan.

Loaf pan: 40–45 minutes
9×9 pan: 30–35 minutes

Check doneness by inserting a toothpick into the center. If it comes out clean or with a few moist crumbs (not wet batter), it’s ready.

If the top browns too quickly, loosely tent with foil during the last 10 minutes.

Step 5: Cool Completely

This step is important.

Let the cake cool in the pan for 10–15 minutes.
Then transfer to a wire rack to cool completely before frosting.

Frosting a warm cake will melt everything — patience pays off!

Why This Recipe Works

The lemon pie filling replaces:

Oil
Extra sugar
Additional liquid
Flavoring

It keeps the cake moist while adding real lemon flavor and sweetness.

The eggs give structure and lift, creating a soft, fluffy crumb without extra fat.

Texture & Flavor Profile

Expect:

Moist but not dense
Light citrus aroma
Sweet with a mild tart finish
Tender crumb
Slightly caramelized edges

It pairs beautifully with coffee, tea, or a light fruit salad.

Making It Extra Guilt-Free

If you’re tracking points or calories, here are ideas:

Skip frosting and dust with powdered sugar
Use light whipped topping
Serve with fresh berries
Make into cupcakes for portion control
Slice thin and pair with Greek yogurt

Beginner Troubleshooting Guide

Cake Sank in the Middle

Oven door opened too early
Underbaked center
Too much mixing

Too Dense

Overmixed batter
Expired cake mix
Eggs too small

Dry Texture

Overbaked
Incorrect oven temperature

Always check your oven with a thermometer if possible — many run hotter than they say.

Fold in ½ cup fresh blueberries before baking.

Storage Tips

Refrigerator: 5–6 days

For best texture, let refrigerated slices sit at room temperature for 15–20 minutes before serving.
