Recipe Story

I have always been a fan of Oreo cookies, especially the ones with chocolate filling. But when I started following a keto diet, I had to give them up.

I missed them so much that I decided to look for a keto-friendly version online. However, most of the recipes I found were either too complicated, too dry, or too bland. 

I wanted something easy recipe that is quick and tasty. So, I experimented with different chocolate keto mug cake recipes, ingredients and ratios until I came up with this amazing recipe.

It’s crumbly and moist at the same time, and the coconut oil instead of butter adds a lot to the Oreo low carb mug cake flavor and texture. It’s like having a mini Oreo cake in a mug.

I love making this mug cake whenever I need a sweet treat or a dessert. It’s so good that I sometimes make two and eat them both. Don’t judge me, it’s keto!

Unlike the keto chocolate mug cake that has a moist and smooth texture, this keto Oreo mug cake mimics the classic Oreo with its crumbly cake layer and creamy filling.

It’s rich in medium-chain triglycerides (MCTs). It effortlessly transforms into ketones, serving as a source of energy. Revel in the richness of lauric acid, an antimicrobial and anti-inflammatory marvel. Let the keto harmony begin!

Instructions

Making this keto Oreo mug cake recipe is super easy and fast. Here are the steps to follow:

Step 1: In a small microwave-safe bowl or microwave-safe mug, melt the butter for the mug cake. Add the egg and vanilla extract and whisk well.

Step 2: Add the dry ingredients: coconut flour, Swerve, cocoa powder, and salt and mix well until you have a smooth batter.

Step 3: Microwave for 90 seconds or until a toothpick inserted in the center comes out clean. The cook time will depend on the power of your microwave.

Step 4: Let the mug cake cool slightly and then cut it into four round slices.

Step 5: In another small microwave-safe bowl, melt the coconut oil for the filling. Add the almond milk, powdered Swerve, and salt and whisk well. You can use a food processor if you prefer.

Step 6: Take two slices of the mug cake and spread half of the filling on one slice. Place the other slice on top and press gently to make a sandwich. Repeat with the remaining slices and filling. If the filling is too runny, leave it in the fridge for a couple of minutes. Do not leave it too long as it will be too hard to spread. If this happens, microwave for 10 seconds.

Step 7: Enjoy your keto Oreo mug cake with a glass of almond milk or some whipped cream. You can also store the leftovers in an airtight container in the refrigerator for up to 3 days.

Frequently Asked Questions (FAQ):

Q: What is a mug cake? 

A: A mug cake is a single-serving cake that is cooked in a microwave in a mug. It’s a quick and easy way to make a cake without using an oven or a lot of dishes.

Q: Why is my keto filling too liquidy and how can I fix it? 

A: The keto filling may be too liquid because of the butter or the almond milk. You can fix it by cooling it in the fridge for a couple of minutes. But don’t let it cool down too much, or it will solidify and be hard to spread. If it becomes too solid, you can heat it up by microwaving it for 10 seconds.

Q: Why use coconut flour for this keto Oreo mug cake? 

A: Coconut flour is a low-carb, gluten-free, and high-fiber flour that is made from dried coconut meat. It’s a great alternative to wheat flour for keto and low-carb baking. It also adds a nice coconut flavor and a moist texture to the cake.

Q: Is coconut oil a must-have in this recipe?

A: Absolutely! Coconut oil isn’t just a flavor enhancer; it’s the keto magician binding all the elements in a creamy embrace. Its richness in MCTs and lauric acid elevates both taste and nutritional value.

Q: Can I substitute almond milk with another dairy-free alternative?

A: Certainly! While almond milk adds a delightful touch, feel free to experiment with your favorite dairy-free alternative to tailor the mug cake to your taste preferences like coconut milk.

Q: How do I store the leftover mug cake sandwiches?

A: You can store the leftovers of this keto Oreo mug cake in an airtight container in the refrigerator for up to 3 days. You can reheat them in the microwave for a few seconds before eating. You can also freeze them for up to a month and thaw them in the fridge overnight.

Q: Can I use a different sweetener than Swerve? 

A: Yes, you can use any keto-friendly sweetener that measures like sugar, such as erythritol, monk fruit, or allulose. However, make sure to adjust the amount according to the sweetness level of your preferred sweetener.

Q: Can I tweak the sweetness level by adjusting Swerve quantities?

A: Absolutely! Swerve is your sweet companion, and adjusting quantities allows you to customize the sweetness to match your preference. Experiment until it’s just right for you.

Q: Is there a recommended cocoa powder for this recipe?

A: Choose a high-quality cocoa powder for the best chocolatey experience. The better the cocoa, the richer the flavor in your keto Oreo mug cake.

Q: How can I add a personal touch to these mug cake sandwiches?

A: Get creative! Consider adding a sprinkle of unsweetened coconut flakes or a drizzle of sugar-free chocolate syrup for that extra touch of decadence. Make it yours!

Indulge in the answers to your burning questions and make your keto journey even more delightful!

Q: What is the difference between keto Oreo mug cake and keto chocolate mug cake? 

A: The main difference is in the texture and the filling. The keto Oreo mug cake has a crumbly cake layer and a creamy filling that resembles the classic Oreo cookie. The keto chocolate mug cake has a moist and smooth cake layer and no filling. Both are delicious and keto-friendly, but the keto Oreo mug cake is more fun and satisfying.

Q: Can I make this mug cake in the oven? 

A: Yes, you can bake this mug cake in the oven if you don’t have a microwave or prefer a more traditional method. Preheat your oven to 180°C (350°F) and grease a small oven-safe ramekin. Follow the same steps as the microwave version and bake for 15 to 20 minutes or until a toothpick inserted in the center comes out clean.

Q: Can I add some chocolate chips or nuts to the mug cake? 

A: Yes, you can customize your mug cake by adding some sugar-free chocolate chips or chopped nuts of your choice. Just make sure to account for the extra carbs and calories that they will add to the recipe.
