1: Preheat oven to 350°F and grease a mini-donut pan with butter.
2: In a bowl, whisk together the flour, baking powder, baking soda, cinnamon, and salt.
3: In a separate bowl, mix together the butter, sugar, maple syrup, eggs, and buttermilk until smooth.
4: Pour the dry ingredients into the wet and stir until you have a smooth donut batter.
5: Pour batter into a gallon ziploc bag, squeeze out excess air, and close it. Cut the bottom corner tip off to pipe the batter.
6: Pipe the donut batter into the well-greased donut pan, filling it 3/4 full, and tap the pan on the counter to release air bubbles.
7: Bake at 350°F for 10-12 minutes.
8: Invert the pan onto a cooling rack and tap out the donuts. Let them cool completely before glazing.
9: For the glaze, whisk together the ingredients until smooth and shiny. If the glaze is too thick, add a teaspoon more of heavy cream.
10: Dip each donut top into the glaze and then top with crumbled bacon. Let the glaze set for 10 minutes before enjoying.
