1. Prepare the Donut Pan and Oven:

• Preheat the oven to 400°F.
• Grease a donut pan with baking spray and set aside.

2. Mix Dry Ingredients:

• In a large mixing bowl, combine the all-purpose flour, cocoa powder, brown sugar, granulated sugar, baking soda, salt, and espresso powder. Mix until well combined and set aside.

3. Prepare Wet Ingredients:

• In a separate bowl, whisk together the egg, brewed espresso (or strong coffee), and half & half.

4. Combine Wet and Dry Mixtures:

• Create a well in the center of the dry ingredients and pour in the wet ingredients.
• Mix until just combined, ensuring not to overmix. The batter will be fairly thick.

5. Add Remaining Ingredients:

• Stir in the sour cream, vanilla extract, and melted butter until the batter is smooth and well-combined.

6. Fill Donut Pan and Bake:

• Carefully pour the batter into the greased donut pan, filling each cavity about 3/4 full. (The batter should yield about 7-8 donuts.)
• Bake in the preheated oven for 8-9 minutes, or until the tops of the donuts spring back when lightly touched.

7. Prepare the Chocolate Glaze:

• While the donuts are cooling, prepare the glaze. In a medium-sized bowl, combine the powdered sugar, cocoa powder, and espresso powder.
• Gradually add the brewed espresso (or coffee) and heavy cream, whisking continuously until smooth.

8. Glaze and Top the Donuts:

• Once the donuts have slightly cooled, dip the top of each donut into the chocolate glaze, ensuring they are well-coated.
• Sprinkle with the crushed chocolate-covered espresso beans.
• Allow the glaze to set for about 10 minutes.

9. Serve and Enjoy:

• Once the glaze has set, serve the donuts immediately and enjoy!
