Method
- Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or grease it thoroughly.
- In a large mixing bowl, whisk together the all-purpose flour, protein powder, granulated sugar, baking powder, 1/2 teaspoon of cinnamon, and salt. Ensure everything is well combined to distribute the leavening agents evenly.1.5 cups all-purpose flour, 0.5 cup vanilla or unflavored protein powder, 0.25 cup granulated sugar, 2 teaspoons baking powder, 0.5 teaspoon ground cinnamon, 0.25 teaspoon salt
- In a separate medium bowl, whisk together the milk, melted butter, egg, and vanilla extract until smooth.1 cup milk, 0.25 cup unsalted butter, melted and slightly cooled, 1 large egg, 1 teaspoon vanilla extract
- Pour the wet ingredients into the bowl with the dry ingredients. Stir gently until just combined. Be careful not to overmix; a few lumps are perfectly fine. Overmixing can lead to tough muffins.
- In a small bowl, combine the softened butter, brown sugar, and 1 teaspoon of cinnamon. Mix with a fork until it forms a crumbly paste.2 tablespoons unsalted butter, softened, 2 tablespoons brown sugar, 1 teaspoon ground cinnamon
- Spoon about half of the muffin batter into the prepared muffin cups, filling each about one-third full.
- Dollop about 1 teaspoon of the cinnamon swirl mixture into the center of each muffin cup, on top of the initial batter.
- Spoon the rest of the muffin batter over the cinnamon swirl, filling each cup about two-thirds to three-quarters full. You want enough batter to cover the swirl completely.
- Using a toothpick or a skewer, gently swirl the batter in each cup. Insert the toothpick into the batter, twist it a few times, and lift it out. This helps create that beautiful marbled effect, reminiscent of actual cinnamon rolls.
- Bake for 18-22 minutes, or until a toothpick inserted into the center of a muffin comes out clean. The tops should be golden brown.
- Let the muffins cool in the muffin tin for 5-10 minutes before transferring them to a wire rack to cool completely.
