These chocolate muffins are super moist and rich with a deep chocolate flavor that really hits the spot! They're so easy to make and are hands down some of the best chocolate muffins I've ever had.
Preheat oven to 190℃ (375℉) conventional (see note 2 if using a convection oven) and line a 12-hole standard muffin tray with muffin liners. This recipe makes about 15 muffins, so line a second tray (if you have one) with a few muffin liners, or see note 3 if you only have one tray.
Sift together flour, baking soda, baking powder and salt. Use a whisk or fork to mix until well combined and set aside for now.
In a large bowl add in cocoa powder, instant coffee powder and hot water. Use a whisk to mix until well combined and smooth.
Add in brown sugar, vegetable oil, vanilla, sour cream and egg. Whisk until well combined and smooth.
Add pre-sifted dry ingredients into wet ingredients and whisk until well combined, but avoid overmixing. Get batter off of whisk as the rest of the mixing will be done with a spatula.
Reserve about 1/3 cup of the chocolate chips for later and add remaining chocolate chips into the batter. Fold with a spatula until just combined. Do not overmix.
Distribute the batter into the muffin liners until they're ¾ full. Do not fill to the top otherwise the muffins will overflow. Sprinkle reserved chocolate chips on the top of the muffins.
Bake for 20-25 minutes (be sure to check at the 20 minute mark to make sure they don't overbake and then bake more if needed) or until a toothpick comes out mostly clean or with a few moist crumbs on it.
Allow the muffins to cool for 10 minutes in the tray, before transferring to a wire rack. Allow them to cool for another 15-20 minutes before eating. Enjoy!
