• Wash and dry produce.

• Zest and halve orange; slice crosswise into 1/2-inch-thick half-moons. Thoroughly shake coconut milk in container before opening.

• Place 1/4 cup coconut milk (1/2 cup for 4 servings) in a medium microwave-safe bowl (be sure to measure—we sent more!). Microwave until bubbling, 40-60 seconds. Immediately add half the chocolate chips and let stand until chocolate has slightly melted, 2-3 minutes.

• Gently whisk chocolate ganache until smooth and shiny, 30-60 seconds more. Wash and dry whisk.

• In a large bowl, whisk together crème fraîche and 1/4 cup water (1/2 cup for 4 servings) until mostly smooth.

• Add tempura batter mix, baking powder, brown sugar, remaining chocolate chips, 1/4 tsp orange zest, and 1/4 tsp salt (1/2 tsp orange zest and 1/2 tsp salt for 4 servings) to bowl; whisk until thoroughly combined, 1-2 minutes.

• Coat two microwave-safe mugs (four mugs for 4 servings) with nonstick cooking spray. Evenly divide batter between mugs. TIP: The batter will be sticky, so use a rubber spatula to transfer to mugs.

• Microwave until mug muffins are springy to the touch and a toothpick inserted into the center comes out clean, 2 minutes. TIP: If needed, continue to microwave in 30-second intervals until muffins are done.

• Let mug muffins cool for 1 minute. Serve straight from the mugs with orange slices and ganache for dipping on the side. TIP: Not serving them right away? Use a butter knife to loosen muffins from mugs and transfer to a plate or container.
