Follow these steps to create delicious Beef, Egg & Cheese Dog Muffins:

1. Preheat your oven to 350°F (175°C).
2. Prepare the Muffin Tin: Grease a 12-cup muffin tin or line it with paper liners.
3. Cook the Ground Beef: In a skillet over medium heat, cook the ground beef until browned. Drain excess fat and set aside to cool slightly.

5. Whisk Eggs: In another bowl, whisk together the eggs, milk, and olive oil until well combined.
6. Combine Mixtures: Pour the egg mixture into the dry ingredients and mix until just combined.
7. Add Beef and Cheese: Fold in the cooked ground beef and shredded cheddar cheese until evenly distributed throughout the batter.
8. Spoon into Muffin Tin: Divide the muffin batter evenly among the prepared muffin cups, filling each about 2/3 full.
9. Bake: Place in the preheated oven and bake for 20-25 minutes or until the muffins are golden brown and a toothpick inserted into the center comes out clean.
10. Cool Before Serving: Allow the muffins to cool in the pan for about 5 minutes before transferring them to a wire rack to cool completely.

By following these steps, you’ll create delicious, fluffy muffins filled with savory goodness.
