Step‑by‑Step Instructions for Keto Pecan Pie Mug Cake

Step 1: Whisk the Batter
In a medium bowl, whisk together 1 egg, 1 tablespoon of melted butter, 2 tablespoons each of coconut flour and almond flour, and 2 tablespoons of heavy whipping cream. Add your choice of low-carb sweetener, 1/4 teaspoon of baking powder, and 1/2 teaspoon of vanilla extract. Mix thoroughly until smooth, ensuring there are no lumps. This coconut and almond flour blend will create the foundation of your delicious Keto Pecan Pie Mug Cake.

Step 2: Prepare the Mug
Grease a microwave-safe mug or ramekin with a little butter to prevent sticking. Once your batter is well mixed and smooth, carefully pour it into the prepared mug, filling it about halfway to allow for rising as it cooks. The visual cue here is to see the batter filling the mug evenly, setting you up for a perfectly baked dessert in just a moment.

Step 3: Microwave the Mug Cake
Place the mug in the microwave and cook on high for 90 seconds. Keep an eye on the cake; it should puff up and the surface should look set but slightly moist. Avoid overcooking, as this can lead to dryness. After 90 seconds, carefully check if the top feels firm to the touch—this indicates your Keto Pecan Pie Mug Cake is ready to enjoy!

Step 4: Caramelize the Pecans
While the mug cake cooks, heat a non-stick pan over medium-high heat. Add 1 tablespoon of butter and your favorite low-carb sweetener, stirring until melted and bubbling. Toss in a handful of chopped pecans, stirring continuously for about 2-3 minutes. Watch for the pecans to become golden and caramelized—the nutty aroma is a sign that they’re beautifully toasted and ready to top your mug cake.

Step 5: Assemble and Serve
Once the mug cake has cooked, remove it from the microwave and let it sit for a moment to cool slightly. Top generously with the warm, caramelized pecans. The richness of the Keto Pecan Pie Mug Cake paired with the crunchy, sweet topping will create a delightful dessert. Enjoy it warm for the best experience—a quick and satisfying treat that’s both indulgent and low-carb!

How to Store and Freeze Keto Pecan Pie Mug Cake

Fridge: Store any leftovers in an airtight container for up to 2 days. Reheat in the microwave for 15-20 seconds for the best texture.

Freezer: If you want to keep the Keto Pecan Pie Mug Cake longer, freeze it in an airtight container for up to 1 month. Thaw overnight in the fridge before reheating.

Reheating: For optimal results, reheat your mug cake in the microwave at low power to avoid drying it out. Enjoy while warm, topped with extra caramelized pecans if desired!

Keto Pecan Pie Mug Cake Recipe FAQs

What kind of egg should I use for the Keto Pecan Pie Mug Cake?
You can use a regular egg for this recipe, which provides structure and moisture. If you’re looking for a vegan option, I recommend substituting it with a flax egg (1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water) for a perfect bind!

How do I store the Keto Pecan Pie Mug Cake?
Store any leftovers in an airtight container in the refrigerator for up to 2 days. Reheating in the microwave for about 15-20 seconds works best to bring back its delicious, fudgy texture.

Can I freeze the Keto Pecan Pie Mug Cake?
Absolutely! To freeze, let the mug cake cool completely, then place it in an airtight container or wrap it tightly in plastic wrap for up to 1 month. When you’re ready to enjoy it, thaw overnight in the fridge, and reheat gently in the microwave.

What should I do if my mug cake comes out dry?
If you find your mug cake is dry, it may have been overcooked. Microwaves vary; try reducing the cooking time by 10-15 seconds and check for doneness—look for a surface that is set but slightly moist. You can also add a bit of extra cream before cooking to maintain moistness.

Is this recipe suitable for people with nut allergies?
Since this Keto Pecan Pie Mug Cake contains almond flour and pecans, it is not suitable for those with nut allergies. Instead, you can experiment with coconut flour as the base and use seeds like sunflower seeds or pumpkin seeds for a crunch, keeping the recipe nut-free.

How can I make this Keto Pecan Pie Mug Cake extra special?
For an extra indulgent treat, consider topping your mug cake with a dollop of sugar-free whipped cream or a scoop of sugar-free vanilla ice cream. Additionally, sprinkling a pinch of cinnamon or nutmeg into the batter can elevate the flavor profile!
