These Happy Birthday Donuts are rich chocolate donuts loaded with chocolate chips and topped with a raspberry frosting and rainbow sprinkles. They're a party in donut form! They're also so simple to make, no mixer is used at all! The batter comes together with just a whisk in less than one hour! If that wasn't enough, they're gluten free, nut free, eggless and can easily be dairy free (vegan).
Preheat your oven to 350 degrees Fahrenheit. Grease 2 donut pan wells with vegetable oil. Set aside.If you don’t have two pans you’ll have to cook the donuts in multiple batches.
In a large bowl, sift together the 1 ¾ cups gluten free flour, ⅔ cup cocoa powder, 1 teaspoon baking soda, 1 teaspoon baking powder, ¾ teaspoon kosher salt and 1 ¼ cups light brown sugar. Then use a whisk to combine and set aside. If you don’t sift, you’ll get large clumps of brown sugar which is fine if that doesn’t bother you.
In a medium bowl, using a spoon, mix together the 4 rounded tablespoons cornstarch and 6 tablespoons water until there are no lumps and it is smooth. It will be thick and tacky at first. Once combined, whisk in the 1 cup milk, 2 teaspoons pure vanilla extract and 2 teaspoons white vinegar.
Add the wet ingredients and the ½ cup vegetable oil into the dry ingredients. If it gets too thick, switch to using a spatula.
Using a spatula, fold in the 1 cup chocolate chips.
Next scoop the batter into a pastry bag or a (zip top bag and cut a corner off) and pipe into the donut pans, filling them about ¾ of the way full.
Bake the donuts in the center rack of the 350 degree oven for 15 minutes. The donuts should be risen and spring back at you when gently touched.Note: If you gently poke the donuts and a dent forms, they're not done baking. You can also insert a toothpick and make sure it comes out clean.
Let the donuts cool in the pans for at least 5 minutes before taking them out. If you try to take them out too soon, they will stick and break apart into a giant mess. Once 5 minutes is up, use a small spatula to loosen them from the pan and cool completely on a cooling rack.
For The Raspberry Frosting
In the large bowl of an electric mixer or using a hand held mixer, beat the ½ cup unsalted butter until smooth; about 2 minutes.
With the mixer on very low speed, slowly add in the 4 cups confectioners' sugar, 1 pinch kosher salt, 2 teaspoons vanilla and 12 frozen raspberries. Then beat until the raspberries break apart and everything is combined.
Then slowly add in the 2.5 tablespoons water a little at a time until you get the desired consistency. You may not need all the water.Once all combined, the frosting will turn pink and there will be flecks of raspberries; that's normal.
Lastly, using an icing spatula or a butter knife, frost the tops of the donuts.Immediately after frosting a donut, scatter the sprinkles and mini chips over the top so they stick.

Notes
For Vegan: Use a gluten free flour free from dairy, vegan sugar, vegan baking sticks, a non-dairy milk and vegan chocolate chips and sprinkles. All Purpose Flour: I cannot test this due to celiac disease, but use 1 ¾ packed cups of regular flour (294 grams), packed ⅓ cup cocoa powder (77.2 grams) and ¾ cup of milk (177.4 ml).Storing: Store the donuts in an airtight container or individually wrap each donut in aluminum foil for up to 2 days in the fridge. Try to create a teepee with the top of the foil so it isn't touching the top of the frosting as much.Let each donut come to room temperature prior to serving. Freezing: Once the frosting on the donuts has hardened a little (you may need to pop them in the fridge), individually wrap each donut in aluminum foil. Pop them in a zip top bag and freeze the donuts for up to 30 days.To defrost, put the donuts in the fridge the night before or leave them out on the counter for 2 hours prior to eating or until the donuts are room temperature and soft.Nutrition: The info below is a generated estimate and is not guaranteed to be accurate.
