Step-by-Step Directions
Follow these simple steps to make the most delicious 🍰🍏Rustic Sourdough Apple Skillet Cake🍏🍰.
1️⃣ Preheat & Prep: Set your oven to 350°F (175°C). Grease your cast-iron skillet with 🧈 butter.
2️⃣ Prepare the Apples: In a bowl, toss the 🍏 apple slices with 🍋 lemon juice, 🍯 honey, and 🌿 cinnamon. Let them sit for at least 5 minutes to soak up all the flavors. Tip: This step helps the apples caramelize beautifully when baked.
3️⃣ Mix the Wet Ingredients: In a large mixing bowl, whisk together 🥚 eggs, 🏺 oil, and 🍞 sourdough discard until smooth. Tip: Whisking thoroughly ensures a uniform texture.
4️⃣ Combine the Dry Ingredients: In another bowl, mix 🌾 flour, 🍰 baking powder, and 🧂 salt. Gradually add the dry mixture to the wet ingredients, stirring gently until just combined. Avoid overmixing to keep the cake light and airy.
5️⃣ Assemble the Cake: Fold in half of the 🍏 apple mixture into the batter to distribute flavor evenly. Pour the batter into your prepared skillet, smoothing the top. Arrange the remaining apples on top in a circular pattern for a rustic presentation.
6️⃣ Bake: Place your skillet in the oven and bake for 40-45 minutes or until golden brown. Insert a toothpick into the center—if it comes out clean, it’s done! Tip: If the edges brown too quickly, cover loosely with foil for the last 10 minutes.
7️⃣ Cool & Serve: Let your cake cool slightly before slicing. Serve warm for the best texture and flavor. Tip: Pair with vanilla ice cream or whipped cream for an extra indulgence! 🍽️
