This cake is completely inspired by Jamie’s Heath Bar Cupcakes. The second I saw them I wanted to make them into a cake! And it was definitely a labor of love.
With the mixer on low speed, slowly add the wet ingredients to the dry. With mixer still on low, add the coffee and stir just to combine, scraping the bottom of the bowl with a rubber spatula. Pour the batter into the prepared pans (it will be very thin) and bake for 35 to 40 minutes, until a cake tester comes out clean.
