Apple cake can turn gummy when the fruit is too wet or tough when the batter is overmixed. This square-pan version uses firm apples cut into small pieces, folds them in after the flour is almost incorporated, and checks doneness in a cake area rather than through a juicy apple pocket.
Oven calibration, pan material, fruit moisture and ingredient measuring can shift the finish. Begin checking at the early end of the range and use the center cues described below.

Why this recipe works
Firm apples hold their shape: Small pieces soften inside the crumb without releasing as much free juice as overripe fruit.
Oil keeps the crumb flexible: Unlike solid butter, oil stays fluid after cooling and supports a moist cake around the apples.
Minimal folding limits toughness: Stopping as soon as the flour disappears avoids unnecessary gluten development.
The first batch is the useful reference point. Measure as written, note the finish in your equipment, and change only one variable at a time if an adjustment is needed.
Ingredients

- 2 cups all-purpose flour, 240 grams, spooned and leveled
- 1 1/2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1 1/2 teaspoons ground cinnamon
- 1/2 teaspoon fine salt
- 2 large eggs, room temperature
- 3/4 cup packed light brown sugar
- 1/2 cup plain Greek yogurt
- 1/2 cup neutral oil
- 1 teaspoon vanilla extract
- 3 cups peeled diced apples, 1/2-inch pieces
- 2 tablespoons coarse sugar, optional topping
Ingredient notes
Apples
Honeycrisp, Pink Lady, Braeburn or Granny Smith hold their shape. Weigh or measure after peeling and dicing.
Greek yogurt
Plain yogurt supplies acidity for the baking soda and moisture for the crumb. Avoid sweetened flavored yogurt.
Flour
For the most repeatable texture, use 240 grams. If using cups, fluff, spoon into the cup and level without packing.
How to make apple cake

1. Prepare the pan
Heat the oven to 350°F. Grease a 9-inch square pan and line the bottom with parchment, leaving two handles.
2. Mix the dry ingredients
Whisk flour, baking powder, baking soda, cinnamon and salt until no leavening lumps remain.
3. Mix the wet ingredients
In a second bowl, whisk eggs and brown sugar for 45 seconds, then whisk in yogurt, oil and vanilla.
4. Combine gently
Fold dry ingredients into wet until a few flour streaks remain. Add apples and fold only until the batter is even.
5. Bake
Spread in the pan, level the top and add optional coarse sugar. Bake 40 to 50 minutes, rotating once after 30 minutes.
6. Check and cool
A tester inserted into a cake area should show moist crumbs, not wet batter. Cool 20 minutes in the pan, then lift out and cool at least 10 minutes more.
Quick timing and doneness guide
| Stage | What to look for | What to do |
|---|---|---|
| Preparation | Small pieces soften inside the crumb without releasing as much free juice as overripe fruit. | Complete the size, moisture or equipment setup before cooking |
| First check | Fold dry ingredients into wet until a few flour streaks remain. Add apples and fold only until the batter is even. | Check at the early end of the range and keep unfinished portions cooking |
| Finished | A tester inserted into a cake area should show moist crumbs, not wet batter. Cool 20 minutes in the pan, then lift out and cool at least 10 minutes more. | Stop when the stated texture or safe temperature is reached |
| If adjustment is needed | Cool at least 30 minutes before slicing with a sharp knife. | Make the smallest useful change, then check again |
This table is a decision guide, not a replacement for ingredient labels, the appliance manual or safe-temperature guidance. When food safety depends on internal temperature, check more than one thick piece with a reliable thermometer.
Substitutions and variations
Whole-wheat option
Replace up to 1/2 cup all-purpose flour with whole-wheat flour and add 1 tablespoon milk if the batter is very stiff.
Nut variation
Fold in 1/2 cup toasted chopped walnuts with the apples.
Dairy-free
Use an unsweetened thick dairy-free yogurt with enough acidity to activate baking soda.
Change one major component at a time. Moisture, sweetness, structure and cooking time affect one another, so several simultaneous substitutions are harder to predict.
Serving ideas
Serve plain, dusted lightly with confectioners’ sugar or with a spoonful of yogurt. A fully cooled slice is sturdy enough for a lunchbox, while a warm slice is softer and best eaten from a plate.
Troubleshooting
The center is gummy
Likely cause: The apples were very wet, the tester passed through fruit or the cake was underbaked.
Fix: Check in two cake-only areas and bake until neither shows wet batter.
The cake is tough
Likely cause: The flour was packed or the batter was mixed too long.
Fix: Measure by weight and fold only until the last flour streak disappears.
The top browns too quickly
Likely cause: The pan is dark or the oven runs hot.
Fix: Tent loosely with foil once the top is set and verify the oven temperature.
The pieces fall apart
Likely cause: The cake was cut while hot and the apple-rich crumb had not set.
Fix: Cool at least 30 minutes before slicing with a sharp knife.
Storage, freezing and reheating
Refrigerator: Store covered at room temperature for 1 day or refrigerate for up to 4 days because the cake contains abundant moist fruit.
Freezer: Wrap individual cooled slices and freeze for up to 3 months.
Reheating or serving after storage: Bring to room temperature or warm one slice for 10 to 15 seconds in the microwave; avoid overheating, which can toughen the edges.

Frequently asked questions
What apples are best for apple cake?
Firm sweet-tart apples that keep their shape work best, including Honeycrisp, Pink Lady, Braeburn and Granny Smith.
Can I leave the apple peel on?
Yes, if the skins are thin and the apples are cut small; peeling gives a more uniform tender crumb.
Why test away from an apple piece?
A fruit pocket stays wet even when the surrounding batter is baked, so it can make a finished cake look underdone.
