- 3/4 cup packed light brown sugar

- 1 1/4 cups water
About the ingredients
Method
- Preheat oven to 320 degrees F. Heat well-seasoned 10-inch cast iron pan over medium-low until butter melts and sugar dissolves in it with maple syrup, salt, and pecans. Stir frequently. Once caramel bubbles and pecans start to toast, remove from heat. You want glossy sauce that’s thickened but not burnt.
- Melt remaining 1/2 cup butter separately. In large bowl mix melted butter, cake mix, eggs, and water briskly for about 2 minutes—too short and batter won’t rise right, too long and it gets tough. Pour batter evenly atop caramel pecan base, look for smooth spread covering all nuts. Slide skillet in oven and bake 50-55 minutes. Watch edges—they darken first. Cake should feel springy and golden, test center with toothpick; a few moist crumbs ok, raw batter no.
- Cool cake about 12 minutes on wire rack. When still warm but not hot, place large plate over skillet and flip quickly but careful—skillet retains heat and caramel sauce bubbles. Pudgy sticky pecans coat top now. Use spatula for any lost nuts from skillet. Best served warm with vanilla ice cream. Cake texture dense, sticky, nutty. Will keep loosely covered day or two but loses crisp edges.
Cooking tips
Chef's notes
- 💡 Butter split helps control texture and flavor. Half in caramel base, half melted for batter. Unsalted best. Maple syrup replaces corn syrup when you want less sweetness but deeper aroma. Watch caramel bubbling; stir often or it scorches fast. Glossy but not burnt is the cue. Pecans toast right in caramel, flavor concentrated. Timing tight. Use medium-low heat only.
- 💡 Flipping warm cake is tricky—skillet retains heat long. Not hot or sauce runs everywhere. Let it cool a bit. Use plate that fits skillet snugly. Thick towel helps grip skillet edge—prevents slips. Release stuck nuts gently with spatula. If syrup sticks, brush skillet edge carefully to loosen. The caramel sets as it cools; too cold means tearing, too hot means leaks.
- 💡 Batter mixing is short. About 2 minutes brisk. Too fast or long scrambles structure and cake toughens, too short batter won’t rise well. Pour gently over caramel-pecan base, move slowly to keep nuts in place. Batter texture should be loose enough to spread evenly but not overflow skillet. Skillet size matters; adjust water if smaller pan to prevent drips and soggy edges.
- 💡 Bake at slightly lower temp (320°F) than box recommends. Prevents over-browning edges before center cooks. Watch edges darken first to nut brown—signal cake near done. Toothpick test still needed; moist crumbs ok, no raw batter. Sound changes too, crackled edge sounds from cast iron better guide than timer. Timing 50-55 min depends on oven characteristics, element placement matters.
- 💡 Extra pecans toast alongside if you want more crunch but watch closely or nuts burn fast. Salt lightly in caramel draws out flavors, balances sweetness. Can dust flaky salt on top after flip for contrast sharpness. Cleanup? Place baking sheet under skillet to catch drips and prevent oven mess. Caramel sauce bubbles but too intense heat ruins base quickly. Stir to spread heat evenly.
Common questions
Why maple syrup instead of golden syrup?
Maple syrup less cloying, deeper warmth in flavor. Golden syrup too sweet, thinner sauce. Swapping changes caramel texture slightly. Maple adds aroma not just sweetness. Works well with pecans because of nuttiness.
How to avoid burnt caramel?
Low heat, medium-low is key. Stir often, watch bubbles size—big bubbles thicken quickly. Remove once gloss shifts but not too dark. Heat carries in pan after removal. If caramel burns, base tastes bitter no good. Alternatives are corn syrup or honey but adjust stirring and heat monitoring.
Cake sticks when flipping?
Usually flipping too hot or too cold. Hot means caramel runs off, sticky mess. Cold means cake grips pan edges. Let cool 10-15 minutes after baking. Use thick towel for firm grip. Gently loosen nuts or edges with spatula first. Some stick is normal. If pan not well-seasoned cast iron, might stick more.
How to store leftovers?
Cake keeps loosely covered at room temp day or two without losing crunch too much. Refrigerate if longer but edges dull faster, texture changes. Warm briefly before serving to soften caramel. Can freeze slices wrapped well. Thaw covered at room temp. Flaky salt topping helps keep flavor fresh after storage.
