Preheat oven to 350°F and prepare cupcake pans by lining with cupcake liners.
Whisk the flour, cocoa powder, baking soda, and salt together.
In a mixer, using paddle attachment, beat the butter, granulated sugar, and brown sugar until light and fluffy.
Add one egg at a time, beating each time until everything is evenly mixed and fluffy, scraping down occasionally.
Add the extracts and beat again until light and fluffy.
Add the yogurt and beat until blended.
Alternate the Guinness and flour mix, blending well, and scraping down occasionally.
Fold in the chocolate chips and bacon pieces, mixing until evenly distributed throughout the batter.
Use a leveled off 1/3 measuring cup to add batter to the cupcake pans.
Bake for 20-25 minutes, until a toothpick comes out clean.
