Preheat a fan-forced oven to 160C (320F) or 180C (356F) for a conventional oven. Line a cupcake tin with cupcake liners.
In the bowl of a stand mixer fitted with the paddle attachment, add the flour, baking powder, caster sugar and salt. Turn mixer on low speed and allow it to mix for a couple minutes to help everything combine well (alternatively you may do this by sifting the ingredients together). Add the softened butter and let it mix until it resembles a fine sand like texture.
Next, add milk, Irish cream, eggs, yogurt, oil and vanilla extract in a large jug and whisk well.
Add wet ingredients to dry ingredients in a slow and steady stream until no dry ingredients are visible. Scrape down the bowl and mix for another 20 seconds.
Add about ¼ cup of batter into 5 different mixing bowls. Colour each one, yellow, blue, purple and orange. Transfer to piping bags and set aside.
Colour the remaining, larger portion of the batter with the teal food gel and mix until well combined. Transfer that to a large piping bag as well.
Pipe a layer of little blobs of each coloured batter and then pipe a layer of teal batter over the blobs. Repeat this another two times or until you’ve filled the cupcake liners ¾ of the way.
To make the donuts, spray a donut baking tin with oil, and brush with a pastry brush. Pipe blobs of coloured batter and then pipe teal coloured batter on top.
Bake donuts for 15 minutes, bake the cupcakes for 30 minutes
Bake for 30 min or until a toothpick inserted comes out clean. Allow them to cool completely on a wire cooling rack.
Core the centre of each cupcake and fill with sprinkles. If you don’t like that, use chocolate sauce.
Fit the end of a piping bag with a Wilton 8b tip and frost a double donut swirl on top of the cupcakes.
Drizzle with chocolate sauce and add donut on top. If the donut won’t say prop something behind it. I’ve also tried inserting a cake pop stick into the bottom of the donut and sticking that in the cupcake.
Drizzle the donut with chocolate. Finish off with sprinkles.
