What You’ll Need for Sweet & Simple Keto Mug Cake

What You'll Need for Sweet & Simple Keto Mug Cake
  • 1 tablespoon (½ oz/14g) butter (softened for easier mixing)
  • 2 tablespoons (1 oz/28g) full-fat cream cheese (softened)
  • 2 tablespoons (½ oz/14g) coconut flour (can substitute with almond flour, but adjust quantity as needed)
  • 1 tablespoon (½ oz/14g) granulated sweetener (e.g., erythritol or monk fruit)
  • 1 teaspoon vanilla extract (for flavor enhancement)
  • ¼ teaspoon baking powder (ensure it’s fresh for best rise)
  • 1 large egg (room temperature works best)
  • 6 raspberries (fresh or frozen, for a burst of flavor)

How to Make Your Keto Mug Cake

  1. Soften the butter and cream cheese: Place the butter and cream cheese in a microwave-safe mug. Microwave for 20 seconds to soften.
  2. Mix the dry and wet ingredients: Add the coconut flour, sweetener, vanilla extract, baking powder, and egg to the mug. Mix thoroughly until smooth.
  3. Fold in the raspberries: Scrape down the sides of the mug, then gently fold in the raspberries to distribute evenly.
  4. Microwave the cake: Microwave for 1 minute (based on a 1200W microwave). Check for doneness—the cake should be firm but moist. If needed, microwave for a few more seconds.
  5. Cool and enjoy: Let the mug cake cool for 5 minutes before eating. Store any leftovers covered at room temperature for up to one day.

Topping Ideas to Elevate Your Mug Cake

Take your Sweet & Simple Keto Mug Cake to the next level with delicious toppings! Try a dollop of whipped cream or a drizzle of sugar-free chocolate syrup for extra indulgence. For a fresh twist, add a few extra raspberries or a sprinkle of unsweetened shredded coconut. Pro tip: A dusting of powdered erythritol can make it look bakery-worthy!

Perfect Pairings for Your Mug Cake

This mug cake pairs wonderfully with a cup of hot coffee or tea for a cozy treat. If you’re feeling fancy, serve it alongside a scoop of keto-friendly vanilla ice cream for a dessert that feels extra special. Bonus: A side of fresh berries adds a refreshing contrast to the rich cake.

Storage and Reheating Tips

If you have leftovers (though it’s hard to resist!), cover the mug with plastic wrap and store it at room temperature for up to one day. To reheat, microwave for 10-15 seconds to bring back that just-baked warmth. Note: For best texture, enjoy it fresh!

Quick Variations to Mix It Up

Feel free to customize this recipe to suit your taste! Swap raspberries for blueberries or dark chocolate chips for a different flavor profile. If you’re nut-free, almond flour can replace coconut flour in equal amounts. Experiment: Add a pinch of cinnamon or cocoa powder for a fun twist!

Microwave Power Tips for Perfect Results

Microwave wattages vary, so keep an eye on your cake to avoid overcooking. Start with 1 minute, then check and add 10-second increments if needed. Remember: The cake should be moist but firm to the touch. If it’s undercooked, a few extra seconds will do the trick!
