❓Slow cooker mug cake❓
What this recipe isn't:
- Actual mug cake - because there are no mugs involved.
What this recipe is:
- A shareable version of the tiktok famous easy dessert.
- The ultimate sweet treat for satisfying your sweet tooth.
- The easiest dessert recipe!
🔪Instructions
This great tik tok recipe just involves a few simple steps:
Preparing Your Slow Cooker
Prepare your slow cooker by coating it with a non-stick agent. Any nonstick cooking spray or oil will work. Avocado oil is my go-to for this recipe.
NOTE: some slow cooker inserts come with a nonstick surface. Use of a non-stick agent is still suggested. However, oil is sometimes recommended rather than spray to protect the longevity of the non-stick surface. Check your slow cooker's manual if you have any concerns.
Alternatively, you can choose to use a slow cooker liner or parchment paper.
Get Cooking

- 🍪 Use a heavy kitchen instrument such as a rolling pin or meat tenderizer to crush oreos.
- 🍪 Add crushed Oreos to greased slow cooker.
- 🍪Add in milk and baking powder and mix it all together.
- 🍪 Cover and cook on low for 3-4 hours or high for ⅕ - 2 hours.



Top Tip
If you serve it promptly it will be gooey-er. If you cook it longer it will have a more cake-like consistency.
🍽Serving suggestions
The possibilities are endless here! My favorite is to set out a ton of favorite toppings similar to a make-your-own sundae bar.
- Ice cream: Scoop some of this warm, easy mug cake recipe into a small bowl. Top with a scoop of vanilla ice cream, a drizzle of caramel sauce, and a handful of chocolate chips.
- Whipped cream and sauce: Top with whipped cream and a drizzle of homemade blueberry sauce, date caramel, salted caramel pear butter, or boozy banana topping (adults only!)
- Crushed yummies: Try adding a crushed version of your favorite ice cream toppings such as pretzel, nuts or candy bars
- Celebration treats: crushed candy canes in winter, marshmallow peeps in spring and even birthday cake icing are all perfect with this chocolate mug cake type dish.
- With a glass of milk: no explanation needed

Why you will love this
I know - I know...you're asking WHY?? Why use a slow cooker to make this recipe when you can make a mug any time in the microwave. The answer is all about cooking time and the occasion.
For a single-serving dessert, I use a mug to make a mini Oreo microwave cake just like everyone else. But, to make a homemade treat for friends or family, this is the easiest cake recipe ever!
And the timing is perfect. Before you start cooking the rest of your dinner, toss this into your slow cooker and walk away. When dinner is over, you have the ultimate home cooked dessert made with basic pantry staples and almost zero effort.
Everyone will love this indulgent treat that takes less time to make than a trip to the bakery.

🔁Substitution ideas
- Use a food processor instead of a bag to crush Oreos for a finer consistency (I am too lazy for this method - it requires washing the food processor afterwards)
- Try oat milk (barista blend is best), almond milk, soy milk, or cashew milk in place of whole milk. This will change the flavor and consistency some, but will still make for a delicious end result
- Play around with Oreo flavors. Vanilla Oreos, Chocolate mint Oreos, and other seasonal Oreo flavors will also make for a delicious cake. Next time, I plan to try it with Nutter Butter cookies - stay tuned!

Storing
Refrigerate leftovers in an airtight container. They will stay good for about 3 days. They can be gently reheated in the microwave or be served cold.
Note
Leftovers will not be as moist as the original and reheating may dry them a bit as well.
😉Hints & hacks
- I always recommend the use of a slow cooker liner. This is, of course, an optional step. I like to purchase my liners in bulk for a less expensive per-piece price.
- If you aren't a fan of slow cooker liners, parchment paper can be used to line your slow cooker for this recipe.
- In the market for a new slow cooker? I love mine!
- Don't forget to plug your slow cooker in and turn it on! 😏
