Preparation

For the glaze:
Place all of the ingredients in the bowl of an electric mixer.
Starting slow, whip with the paddle attachment until smooth and lump-free and just slightly thicker than pouring consistency.
Adjust with more powdered sugar and cream if necessary.
For the donuts:
In a small bowl, dissolve the yeast in the water and let stand for 5 minutes.
Then, place all of ingredients in the bowl of an electric stand mixer and mix on medium speed until the dough gathers on the hook.
Turn out onto a lightly floured board and knead just until smooth.
Divide the dough into 2 pieces and refrigerate for 30-60 minutes.
Remove 1 piece of dough from the refrigerator at a time and roll to 1/2-inch thickness.
Punch with a 2-inch donut cutter (or a 2-inch round cutter and a plain piping tip).
Let proof at room temperature until slightly puffed, about 10-15 minutes.
Heat 1-inch oil in a skillet to 350 degrees and fry for 15-30 seconds on each side.
Let the donuts cool and then glaze.
For the burger:
Season the beef with salt and pepper, to taste.
Divide up into 10 evenly sized balls and press down into patties.
Preheat the grill on medium-high heat and lightly coat the grates with oil.
Grill the burger patties to the desired temperature.
Add a slice of Cheddar on top of each patty.
Slice each donut down the middle, placing the patty in between and top with a light spread of mayonnaise.
Top with the other donut slice and serve.
