Ingredients

Scale

Cake Batter

  • 3 tbsp spelt flour (white, oat, or almond flour)
  • 1/4 tsp baking powder
  • 1/16 tsp salt
  • Pinch uncut stevia OR 1 tbsp sugar
  • 1 tbsp + 2 tsp water
  • 2 tsp oil or buttery spread (or applesauce for low-fat)
  • 1/4 tsp pure vanilla extract

Streusel Topping (Optional)

  • 1/8 tsp cinnamon
  • 1 1/4 tsp sucanat or brown sugar (or keto sweetener)
  • 1/4 to 1/2 tsp oil or butter (or applesauce for low-fat)
  • Tiny pinch salt
  • 2 pecan or walnut halves

Instructions

  1. Prepare Equipment and Preheat Oven (if baking): If using an oven, preheat it to 330°F. Grease a muffin tin, ramekin, or microwave-safe mug depending on your cooking method.
  2. Mix Dry Ingredients: In a bowl, combine the spelt flour, baking powder, salt, and your choice of sweetener (stevia or sugar). Mix well to evenly distribute the leavening agent and sweetener throughout the flour.
  3. Add Wet Ingredients: Pour in the water, oil or buttery spread (or applesauce for low-fat option), and vanilla extract. Stir gently until just combined; avoid overmixing to keep the cake tender.
  4. Prepare Streusel Topping (optional): In a small bowl, mix together cinnamon, brown sugar or keto sweetener, oil or butter (or applesauce), salt, and chopped pecan or walnut halves. This streusel adds a delicious, crunchy texture and warm flavor.
  5. Assemble Cake: Fill your greased container halfway with the batter. Sprinkle about two-thirds of the streusel mixture on top. Spoon the remaining batter over the streusel, then sprinkle on the remaining streusel to finish.
  6. Cook the Cake: Bake in the preheated oven for 12-13 minutes, or microwave on high for about 1 minute (microwave time may vary depending on wattage). The cake should rise and be set but still moist inside.
  7. Cool and Serve: Allow the mug cake to cool slightly before eating to avoid burning and let the flavors meld. Enjoy straight from the mug or transfer to a plate.

Notes

  • Microwave cooking times vary widely; start checking at 50 seconds to prevent overcooking.
  • The streusel topping is optional but highly recommended for added texture and flavor.
  • You can substitute spelt flour with white, oat, or almond flour based on preference or dietary needs.
  • For a low-fat version, replace oil or butter with applesauce but note that texture may be less rich.
  • Using a microwave-safe mug or ramekin ensures safe and even cooking in the microwave method.
  • Doubling the streusel ingredients will create a more generous topping.
  • Ensure not to overmix the batter to keep the cake light and fluffy.
