- Saucepan or microwave-safe bowl (for glaze)
- Measuring cups and spoons
- Cooling rack
Ingredients
Bundt Cake Batter
- 1 cup salted butter (or use coconut oil if preferred)
- 1/2 cup unsweetened cocoa powder
- 1 cup water or brewed coffee, warm
- 1 1/2 cups keto-friendly flour blend (e.g., almond-based low-carb flour)
- 1 cup powdered keto sweetener like monkfruit/erythritol blend
- 1 1/2 teaspoons baking soda
- 1 teaspoon baking powder (optional for slightly more rise)
- 2 large eggs, at room temperature
- 1/2 cup heavy cream
- 1 teaspoon white vinegar
- 1 1/2 teaspoons vanilla extract
Chocolate Glaze
- 1/2 cup heavy cream
- 3/4 cup sugar-free chocolate chips
- 2 teaspoons butter
- 3/4 teaspoon vanilla extract
Instructions
- Preheat your oven to 350°F (175°C).
- Grease and lightly flour a bundt cake pan so the cake releases easily.
- In a saucepan over low heat, combine butter, cocoa powder, and the warm water or coffee; stir until melted and smooth.
- Remove the chocolate mixture from heat and let it cool slightly.
- In a separate bowl, whisk together the dry ingredients: keto flour blend, powdered sweetener, baking soda, and baking powder.
- In a large bowl, whisk the warm chocolate mixture with eggs, heavy cream, vinegar, and vanilla until smooth.
- Gradually add the dry ingredients to the wet mixture, stirring gently until mostly combined; do not overmix.
- Pour the batter into the prepared bundt pan and smooth the top.
- Bake at 350°F (175°C) for 5 minutes, then reduce oven temperature to 325°F (160°C) and continue baking for about 35–40 minutes, or until a toothpick inserted into the center comes out mostly clean.
- Allow the cake to cool completely in the pan before turning it out onto a cooling rack.
- To make the glaze, heat the heavy cream until just warm (do not boil), then pour it over the chocolate chips and butter in a bowl. Let sit briefly; stir until smooth and glossy.
- Stir in the vanilla, then drizzle the glaze over the cooled bundt cake. Let set before slicing.
