Preheat your oven to 180C/350F. It's important to ensure the oven is fully heated so the muffins bake evenly. Line a 12-count muffin tin with muffin liners to simplify cleanup and prevent sticking.
In a large bowl, combine whipped cottage cheese, olive oil, eggs, milk, and vanilla extract. Use a whisk to mix everything together until it’s fully combined. You want a smooth batter, so make sure there are no lumps.
In another bowl, mix together flour, sugar, baking powder, and salt. This step ensures the dry ingredients are evenly distributed before combining with the wet.
Gently fold the dry ingredients into the wet mixture. Be careful not to overmix; you want to combine until just incorporated. The batter should be lumpy, but there should be no dry flour visible.
Now, it's time to add the chocolate chips. Carefully fold them into the batter for a delightful chocolate surprise in every bite.
Evenly distribute the muffin batter into the prepared muffin liners, filling each about 2/3 full. This amount will allow room for the muffins to rise without overflow.
Place the muffin tin in the preheated oven and bake for 17 to 19 minutes. You’ll know they’re done when a toothpick inserted into the center comes out mostly clean, with a few moist crumbs.
Once baked, remove the muffins from the oven. Allow them to cool in the tin for about five minutes. This helps set their structure, making them easier to transfer.
After cooling slightly, transfer the muffins to a wire rack to cool completely. This step is crucial for achieving the perfect muffin texture.
