Why Chiffon Needs 175°C
At 175°C (347°F), chiffon cakes achieve the perfect balance between structure-setting and gentle baking. This prevents the dreaded post-cooling collapse while maintaining the signature fluffy texture.
💡 The Science of 175°C for Chiffon
- Even heat penetration: Center cooks through without over-browning edges
- Protein structure sets properly: Eggs coagulate gradually, locking in air bubbles
- Oil stays emulsified: Maintains moisture without separating
- Minimal collapse risk: Cake sets fully before cooling contraction begins
Chiffon cakes are extremely temperature-sensitive. Just 10°C difference between 175°C and 185°C can mean the difference between success and collapse.
175°C vs 180°C: Critical Difference
Many recipes call for 180°C (350°F), but 175°C produces superior results for chiffon cakes, especially in Asia where chiffon is most popular.
| Temperature | Surface Result | Interior Result | Collapse Risk |
|---|---|---|---|
| 175°C (Recommended) | Light golden, even color | Soft, fluffy, moist throughout | Low - sets properly |
| 180°C | Dark edges, burnt surface | Center may be underdone, dry edges | High - uneven cooking |
Why 175°C is Better
- Gentler rise: Cake rises evenly without rapid expansion that weakens structure
- Even browning: Surface gets light golden color without burning
- Center cooks through: No raw batter in middle, no over-cooked edges
- Better moisture retention: Lower temp means less evaporation
- Lower collapse rate: Properly set structure holds up during cooling
175°C vs 170°C Comparison
| Temperature | Baking Time | Top Shape | Best For |
|---|---|---|---|
| 175°C | Standard time (35-40 min for 8") | Slight dome, attractive | Most chiffon cakes, standard recipes |
| 170°C | +10 minutes longer | Flatter top | Large cakes (10"+), ovens that run hot |
When to use 170°C: If your oven runs hot, if making very large cakes (10" or bigger), or if you prefer completely flat tops for easier decorating. The trade-off is 10 minutes longer baking time.
Chiffon No-Collapse Temperature Control
Chiffon cake collapse is mostly a temperature issue. Master these tests and your collapse rate will drop dramatically.
Three Tests for Perfect Doneness
-
Jiggle Test
Gently shake pan - cake should barely jiggle. If it waves like jelly, needs more time.
-
Toothpick Test
Insert in center - should come out with few moist crumbs, not wet batter. Completely clean = over-baked.
-
Touch Test
Lightly press top - should spring back immediately. If finger leaves dent, needs more time.
⚠️ Critical: Invert Cooling
Even at perfect 175°C, chiffon will collapse if cooled right-side up. Immediately invert after removing from oven.
- Why: Prevents gravity from compressing delicate structure
- How: Turn pan upside down on bottle neck or cooling feet
- Duration: Cool completely (2-3 hours) before removing from pan
- Must do: This is non-negotiable for chiffon success
Different Pan Sizes Temperature Adjustment
| Pan Size | Temperature | Baking Time | Notes |
|---|---|---|---|
| 🎂 6 inch | 175°C | 30-35 minutes | Smaller mass, cooks faster |
| 8 inch (Standard) | 175°C | 35-40 minutes | Most common size, baseline timing |
| 10 inch | 170°C | 45-50 minutes | Lower temp prevents burnt edges |
| Cupcakes (Standard) | 175°C | 18-22 minutes | Small volume, watch carefully |
| Sheet Pan (9x13") | 175°C | 25-30 minutes | Thinner layer, bakes quickly |
Pan Material Matters
- Aluminum (best): Even heat distribution, use 175°C as stated
- Dark non-stick: Absorbs more heat, reduce to 170°C
- Glass: Retains heat longer, reduce to 165°C and add 5-10 min
- Silicone: Not recommended for chiffon - poor heat transfer
Chiffon vs Sponge vs Angel Cake Comparison
| Cake Type | Temperature | Key Ingredient | Texture |
|---|---|---|---|
| Chiffon Cake | 175°C (350°F) | Oil + whole eggs + egg whites | Moist, fluffy, tender |
| Sponge Cake | 175-180°C (350-355°F) | Whole eggs (no oil) | Light, airy, slightly dry |
| Angel Food Cake | 165-170°C (325-340°F) | Egg whites only (no fat) | Very light, cloud-like, chewy |
175°C works for all three but is optimized for chiffon. Sponge can handle up to 180°C, while angel food benefits from slightly lower 165-170°C to prevent over-browning.
Water Bath Light Cheesecake at 175°C
Japanese-style light cheesecake (soufflé cheesecake) uses 175°C for 35 minutes - a faster alternative to traditional low-and-slow baking.
| Method | Temperature | Time | Result |
|---|---|---|---|
| 175°C Quick Method | 175°C water bath | 35 minutes | Chiffon-like texture, light golden top, faster |
| Traditional Low & Slow | 140°C water bath | 70 minutes | Denser, creamier, pale color, traditional |
175°C Cheesecake Method
- Wrap springform pan bottom with aluminum foil (prevent leaks)
- Place pan in larger roasting pan
- Pour batter into prepared pan
- Add hot water to roasting pan (halfway up sides of springform)
- Bake at 175°C for 35 minutes until top is light golden and center barely jiggles
- Cool in oven with door ajar for 30 minutes to prevent cracking
Frequently Asked Questions
Why does my chiffon collapse after cooling?
Most likely under-baked. At 175°C, chiffon needs full 35-40 minutes for 8" pan. Test doneness: 1) Cake barely jiggles when shaken, 2) Toothpick has moist crumbs (not wet batter), 3) Top springs back when touched. Also critical: must invert immediately after baking and cool upside-down completely (2-3 hours).
175°C vs 180°C - which is better for chiffon?
175°C is better. At 180°C, chiffon surfaces brown too quickly while centers remain under-baked, leading to collapse. 175°C provides even heat penetration with light golden surface and properly set interior. The 5°C difference is critical - it's the difference between success and collapse.
Can I use 175°C for regular sponge cake?
Yes, absolutely. 175°C works excellently for sponge cakes, genoise, and other foam-based cakes. Sponge can tolerate up to 180°C, but 175°C produces more even browning and reduces risk of dry edges. Baking time is similar: 25-30 minutes for layers, 35-40 minutes for whole cakes.
Should I open oven door while baking chiffon at 175°C?
No, never before 30 minutes. Opening oven door causes temperature drop and sudden air movement, which can collapse the delicate structure. Only open after minimum 30 minutes when structure has mostly set. If you must check, do so very quickly (5 seconds max) and gently close door.
Fan oven adjustment for 175°C chiffon?
Reduce to 160°C for fan/convection. Fan ovens circulate air more efficiently, effectively increasing heat transfer. Set to 160°C (about 15°C lower) to achieve same results as conventional 175°C. Some bakers prefer conventional mode for chiffon to avoid uneven air currents that can cause lopsided rise.

Summary: 175°C (347°F / 350°F)
175°C is the sweet spot for chiffon cakes - gentle enough to prevent surface burning, hot enough to set structure and prevent collapse. Bake 8" chiffon for 35-40 minutes, test with jiggle/toothpick/touch methods, and immediately invert to cool. This temperature also works perfectly for sponge cakes, angel food cake, and Japanese soufflé cheesecakes. Choose 175°C over 180°C for superior moisture and lower collapse risk.
