01 - Preheat oven to 400°F and line a 12-cup muffin tin with paper liners or grease thoroughly.
02 - Toss diced sweet potato with olive oil and salt. Arrange on a baking sheet and roast for 15 minutes, until tender and lightly caramelized. Allow to cool slightly.
03 - In a large mixing bowl, whisk together flour, baking powder, baking soda, kosher salt, and smoked paprika.
04 - In a separate bowl, whisk eggs, milk, yogurt or sour cream, melted butter, and honey until fully incorporated.
05 - Add wet ingredients to dry mixture and gently fold until just combined, avoiding overmixing.
06 - Fold roasted sweet potato, grated cheddar, and cubed cream cheese into the batter.
07 - Distribute batter evenly into the prepared muffin tin.
08 - Dissolve baking soda in water. Brush muffin tops generously with the solution and sprinkle with pretzel salt or coarse sea salt.
09 - Transfer muffin tin to oven and bake for 20 to 25 minutes, until golden and a toothpick inserted in the center emerges clean.
10 - Let muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely. Serve warm or at room temperature.
