Giant keto skillet pancake puff is a one-pan Dutch baby that delivers pancake joy without the carbs or the flipping. Butter melts in the skillet while the oven heats, then a simple egg-and-coconut-flour batter puffs dramatically in about 20 minutes. Slice it into quarters and eat it straight from the oven.
There’s nothing quite like a Southern breakfast, and for me, that always meant a towering stack of fluffy pancakes. I have the fondest memories of pancake houses dotting the Smoky Mountains, a sweet aroma hanging in the air. But going keto put a damper on those carb-filled cravings. I missed the comfort, but not the hassle of flipping endless batches. That’s where this glorious creation comes in: a giant, puffy, golden skillet pancake! It’s a show-stopping, one-pan wonder that delivers all the pancake joy without the carbs or the effort. It’s the perfect lazy weekend breakfast, keto-style!
Ingredients
• For the Pancake
• 2 tablespoons / 28g (0.99 oz) salted butter
• 4 large eggs
• ¼ cup / 60ml (2 fl oz) water
• ¼ cup / 60ml (2 fl oz) heavy whipping cream
• 2 tablespoons / 14g (0.49 oz) coconut flour
• 2 tablespoons / 24g (0.85 oz) granular erythritol
• ½ teaspoon / 2.5ml (0.1 fl oz) vanilla extract
• ¼ teaspoon / 1.5g (0.05 oz) salt
• For Garnish (Optional)
• Fresh blueberries
• Confectioners’-style erythritol
Instructions
1. Preheat the oven to 425°F / 220°C. Place the butter in a 10-inch cast-iron skillet and set it in the oven to melt while it preheats.
2. In a medium bowl, whisk the eggs until frothy. Add the water, heavy cream, coconut flour, granular erythritol, vanilla, and salt. Stir until the batter is smooth and well-blended.
3. Carefully remove the hot skillet from the oven. Swirl the melted butter to coat the bottom and sides, then pour the batter into the center of the skillet.
4. Bake for 18 to 20 minutes, until the pancake is dramatically puffed and golden brown. Slice into quarters and serve immediately, garnished with fresh blueberries and a dusting of confectioners’-style erythritol, if desired.
