INGREDIENT NOTES & SUBSTITUTIONS
Joe Joe’s sandwich cookies: Of course, you can also use traditional Oreo’s or store-brand sandwich cookies. I like to experiment with different flavors, too. The peppermint “Christmas” ones are delicious used in this recipe!
Powdered sugar: Powdered sugar dissolves well and works perfectly in this recipe. If you don’t have any on hand, regular granulated sugar is fine, but just note that it may not dissolves into the cake quite as well.
Chocolate chips: There’s a lot of sweetness going on in this dessert, so I usually opt for semi-sweet chocolate chips.
Toppings: Vanilla ice cream or whipped cream are traditional, but experiment with others! Chocolate syrup, nuts, cherries, peanut butter drizzle, or caramel sauce would all be wonderful, too!
CASEY’S TIPS
- Use the right mug: Use a microwave-safe mug that’s at least 8 to 12 ounces so the cake doesn’t spill over the top. I prefer a wide-mouthed coffee cup such as these.
- Adjust time: All microwaves cook a bit differently. Start by microwaving the cake for 1 minute. If the mixture seems too gooey for your liking, pop it back in for another 15 seconds and it will be more cake-like. I personally like this cake when it’s nice and gooey, but adjust to your preference!
- Let it rest: Let this chocolate chip mug cake rest for 1-2 minutes before digging in! The cake will finish setting as it cools slightly.
- Double up: You can double the recipe for two people and make it in a larger mug (at least 12-16 ounces). Just adjust the cooking time up about 15-30 seconds.

Chocolate Chip Mug Cake {using Trader Joe’s Joe-Joe’s Cookies}
Ingredients
- 4 Trader Joe's Joe-Joe's cookies + 1 more for topping Oreos or another brand sandwich cookie also works!
- 2 tbsp. milk
- 1/4 tsp. baking powder
- 1 tbsp. all-purpose flour
- 2 tbsp. semi-sweet chocolate chips
- 1 tbsp. powdered sugar you can use regular sugar, too but just note that it doesn't dissolve quite as well
- 1/2 tsp. vanilla extract
- pinch of sea salt (about 1/8 tsp.)
- Vanilla ice cream or whipped cream for topping
Instructions
- Prep: Place 4 Joe's Joe's + all other ingredients (aside from the whipped cream/ice cream!) into a large (at least 8 oz.) mug.
- Mash: With a fork, mash the ingredients until the mixture is smooth, dark brown, and glossy.
- Cook: Microwave for one minute. Let the mug cool in the microwave for an additional minute. Note: Cook time will vary a bit depending on your microwave. Start with 1 minute–if the mixture seems too gooey for your liking, pop it back in for another 15 seconds and it will be more cake-like.
- Finish: Remove the mug from the microwave. Crush the remaining Joe Joe cookies over the top of the cake and top with lots of vanilla ice cream or whipped cream!
