What You’ll Need for Your Keto Chocolate Chip Mug Cookie
- 1 tablespoon butter (use unsalted if adding salt, or salted butter and omit the salt)
- 1 tablespoon sugar-free sweetener (e.g., erythritol or monk fruit)
- ¼ teaspoon vanilla extract
- ⅛ teaspoon salt (skip if using salted butter)
- 1 egg yolk
- 2 tablespoons almond flour
- 2 teaspoons coconut flour
- 1 tablespoon keto chocolate chips (or sugar-free chocolate chips)
How to Make Your Keto Chocolate Chip Mug Cookie
- Melt the butter and sweetener: Place the butter and sugar-free sweetener in a large (10 oz.) microwave-safe mug or ramekin. Microwave for about 20 seconds, or until the butter is melted.
- Mix in wet ingredients: Add the vanilla extract, salt (if using), and egg yolk to the mug. Stir until everything is well combined.
- Add the dry ingredients: Sprinkle in the almond flour and coconut flour. Stir until the mixture is smooth and no dry spots remain.
- Fold in the chocolate chips: Gently mix in the keto chocolate chips until they are evenly distributed throughout the batter.
- Cook in the microwave: Microwave the mug for 45-50 seconds, or until the cookie has risen and the top looks firm. Tip: Start with 45 seconds and add more time if needed. Avoid cooking past 1 minute, as the cookie will continue to set as it cools.
- Serve and enjoy: Let the cookie cool for a minute or two, then enjoy it plain or topped with keto-friendly ice cream for an extra treat!
Topping Ideas to Elevate Your Mug Cookie
Take your Keto Chocolate Chip Mug Cookie to the next level with these tasty toppings! Add a dollop of keto whipped cream or a scoop of sugar-free vanilla ice cream for a creamy contrast. For a crunchy twist, sprinkle with chopped nuts or a dusting of cocoa powder. Feeling indulgent? Drizzle with sugar-free chocolate syrup or a sprinkle of sea salt for a sweet-and-salty finish.
Storage and Reheating Tips
If you have leftovers (though it’s hard to resist eating it all!), store your mug cookie in an airtight container at room temperature for up to 1 day. To reheat, microwave for 10-15 seconds until warm and gooey again. For a crispier texture, pop it in a toaster oven for a minute or two. Just avoid overcooking to keep it soft and chewy!
Recipe Variations to Mix It Up
Customize your mug cookie to suit your cravings! Swap the chocolate chips for keto-friendly white chocolate chips or chopped sugar-free caramel pieces. Add a pinch of cinnamon or nutmeg for a warm, spiced flavor. For a nut-free option, replace almond flour with sunflower seed flour or extra coconut flour (adjust to 1 tablespoon). The possibilities are endless!
Time-Saving Tips for Busy Bakers
Pre-measure your dry ingredients ahead of time and store them in a small jar or bag for a quick grab-and-go option. Use a pre-whisked egg yolk stored in the fridge to save a step. If you’re making multiple servings, double or triple the recipe and mix in a bowl before dividing into mugs. This way, you can enjoy a fresh cookie in minutes whenever the craving strikes!
