How to make coffee donuts in the oven

• Cream the butter with powdered sugar until fluffy.
  110 g butter, 150 g powdered sugar
  
• Add the egg and a tablespoon of flour mixed with baking soda and baking powder to the mixture - mix briefly until combined.
  1 egg, 350 g wheat flour - all-purpose, 1 teaspoon baking soda, 1.5 teaspoons baking powder
  
• Pour in the coffee and mix briefly.
  80 ml strong coffee
  
• Add about half of the flour and mix on low speed.
  
• Add the yogurt and mix briefly.
  160 ml Greek yogurt
  
• Add the rest of the flour and mix briefly - just until combined. The batter will be thick - if it seems too thick, add a little more yogurt or some milk.
  
• Transfer the batter to a thick piping bag and cut off a corner.
• Grease the donut pan with butter and dust with flour.
• Using the piping bag, pipe the donut batter into the mold.
  
• Bake the coffee donuts in an oven preheated to 180 degrees Celsius (top/bottom heat mode) for about 10 minutes - until a skewer comes out clean.
• Carefully remove the donuts and place them on a wire rack to cool.
• Lightly grease the mold again with butter and dust with flour, pipe out the second batch of donuts and bake as before.
• Dip the cooled donuts in coffee glaze - mix powdered sugar with coffee - add coffee gradually and mix the glaze thoroughly. It should be slightly runny to nicely coat the donuts.
