These Birthday Muffins are beautiful rainbow muffins that have sky high domes while being light and airy. They're the perfect breakfast for birthdays, St.Patrick's Day or any day when you want a little party in the morning! They're so easy to make (no mixer is needed); you'll have 6 jumbo muffins in under an hour! If that wasn't enough, they're gluten free, nut free, eggless and can easily be vegan!
Preheat your oven to 375 degrees Fahrenheit. Grease a jumbo 6 cup muffin tin with vegetable oil, in the wells and on the top.
In a large bowl, with a whisk, mix together the 1 ¾ cups plus 2 tablespoons gluten free flour, the ¾ cup sugar, 2 teaspoons baking powder, ½ teaspoon baking soda and the ¼ teaspoon kosher salt. Set aside.
In a medium bowl, mix the 2 heaping tablespoons of cornstarch with 3 tablespoons water until it is thin and watery. It will be thick and tacky at first.
In a large measuring cup, measure out 1 ⅓ cups milk. Add in cornstarch water, the ⅓ cup plus 2 tablespoons vegetable oil and the 2 teaspoons pure vanilla extract. Whisk to combine.
Using a whisk, slowly mix the liquid ingredients into the dry until just combined. When the batter gets too thick, switch to a spatula.
Pour in the ½ cup rainbow sprinkles and use a spatula to gently fold them in until they're combined throughout. Be careful not to over-mix or the batter will turn colors.
Using an ice cream scoop, fill each muffin cup to the top. Smooth the batter with the back of the spoon or a small knife.Sprinkle some of the additional 1 tablespoon of sprinkles onto the tops of the muffins and gently press down so they stick. You may not need all the sprinkles.
Bake in the center rack of the 375 degree oven for 28 minutes until the muffins are golden on top, risen and springy when carefully touched.
Once out of the oven, let the muffins cool in the pan for about 5-10 minutes. Then remove from the pan using a small spatula and let cool on a wire cooling rack.
