In a skillet over medium heat, start by browning the ground beef. Make sure to break it up into small pieces with a spatula. You'll want it to be fully cooked and browned, which should take about 5 to 7 minutes. Once it’s no longer pink, drain any excess fat.
Next, add the taco seasoning to the cooked beef along with 2/3 cup of water. Stir everything together until the beef is well coated. Bring the mixture to a simmer, then let it cook for about 5 minutes. This will allow the flavors to meld beautifully.
While your beef mixture is simmering, take your pizza dough out of the can. Unroll it carefully and cut it into 12 equal squares. This can be a fun part, especially for the kids!
Preheat your oven to 425 degrees Fahrenheit. Now, grab a muffin tin and spray it lightly with cooking oil. This will prevent the dough from sticking and make cleanup a breeze.
Place one square of dough into each muffin cup, pressing it down gently to fit snugly against the bottom and sides. You'll want to create a little cup to hold your filling.
Now, it’s time to fill those cups! Spoon in the ground beef mixture until each cup is filled to the top, about a 1/4 cup each. Don’t be shy; these are meant to be hearty!
Once your filling is in, place the muffin tin in the preheated oven. Bake for 10 to 12 minutes, or until the dough turns a beautiful golden brown. Keep an eye on them; the smell will be mouthwatering!
While the muffin cups are baking, melt your velveeta cheese over medium heat in a saucepan. Add the milk and stir frequently until the cheese is smooth and creamy.
When the muffin cups are done baking, remove them from the oven and let them cool slightly. Carefully lift each muffin cup out of the tin.
To serve, drizzle the melted cheese over each Taco Muffin Cup. Top with fresh lettuce, tomatoes, and black olives. A dollop of sour cream on top is the perfect finishing touch!
