Why You’ll Love This Keto Coffee Cake

If you’ve ever tried a keto dessert that tasted like cardboard, you’ll be thrilled with this recipe. Here’s why it’s a must-make:

✅ 1. Truly Low-Carb & Keto-Friendly

Traditional coffee cake can pack 30g+ carbs per slice—ours has just 3-4g net carbs!
Uses keto-approved sweeteners like erythritol or monk fruit (no sugar spikes!).

✅ 2. Unbelievably Moist & Fluffy

Many keto cakes turn out dry, but sour cream (or Greek yogurt) keeps this one tender.

The perfect crumb—no one will guess it’s grain-free!

✅ 3. Easy to Customize

Add-ins: Chopped nuts, sugar-free chocolate chips, or berries.
Swirl options: Cinnamon, pumpkin spice, or a cream cheese ribbon.

✅ 4. Meal-Prep & Freezer-Friendly

Stays fresh for 3 days at room temp or 3 months in the freezer.
Great for quick breakfasts or last-minute guests.
