Ingredients
  

  • 2 tbsp avocado oil (or melted coconut oil)
  • 3 tbsp almond flour (fine-ground for best texture)
  • 1 large egg
  • ½ tsp vanilla extract
  • ½ tsp ground cinnamon
  • ½ tsp baking powder
  • 1 tsp monk fruit sweetener (or stevia, to taste)

For the Cream Cheese Glaze:

  • 2 tbsp whipped cream cheese
  • 1 tbsp water (or heavy cream for extra richness)
  • Pinch of cinnamon for garnish

Instructions
 

  • Mix the batter: In a microwave-safe mug, whisk together oil, almond flour, egg, vanilla, cinnamon, baking powder, and monk fruit until smooth. The mixture should look like slightly thick pancake batter.
  • Microwave: Place the mug in the microwave and cook on high for 90 seconds. Cooking time may vary by microwave wattage, so check for doneness — the cake should spring back lightly when touched.
  • Release and plate: Run a butter knife gently around the edges, then invert the mug onto a plate. The cake should slide out easily.
  • Make the glaze: Using the same mug (no need to clean it), add cream cheese and water. Microwave for 20–25 seconds until soft, then stir until smooth.
  • Drizzle and enjoy: Pour the glaze over your warm cinnamon roll cake and sprinkle with a touch of cinnamon. Serve immediately for that gooey, just-baked magic.
