Step by Step Instructions
Begin by preheating your oven to 350 degrees F. Line your baking dish with parchment paper, allowing a bit of overhang for easy removal later.
Start with the apple cinnamon puree. Add the diced zucchini, apple cider vinegar, apple extract, lemon juice, monkfruit sweetener, cinnamon, and butter to a non stick pan. Place over medium heat and bring gently to a boil. Reduce the heat to medium low and simmer for about ten minutes. Stir occasionally until the mixture thickens and the zucchini becomes soft and translucent. Remove from heat and allow it to cool slightly. Blend with a hand blender until smooth, leaving a few small chunks if you prefer a more apple like texture. Place the puree in the refrigerator to cool while preparing the cake base.
In a large mixing bowl, add the eggs and monkfruit sweetener. Whisk vigorously for about two minutes until the mixture becomes pale, airy, and fluffy. This step is important for creating a light cake texture.
In a separate bowl, combine almond flour, coconut flour, baking powder, cinnamon, and salt. Mix thoroughly to ensure even distribution of leavening.
Add the cooled apple cinnamon puree, Greek yogurt, and vanilla flavor to the egg mixture. Use an electric mixer on low speed to combine. Slowly add sparkling water while mixing until the batter is smooth and pourable.
Pour the batter evenly into the prepared baking dish. Smooth the top gently with a spatula. Bake for thirty five to thirty seven minutes. The cake is ready when a skewer inserted in the center comes out mostly clean with a few moist crumbs. If the top browns too quickly, loosely cover with foil during the final minutes.
Remove the cake from the oven and allow it to cool completely. Once cooled, use the handle of a wooden spoon to poke holes evenly across the surface, reaching almost to the bottom.
To prepare the custard, add the heavy cream and almond milk to a saucepan. Heat gently until just below boiling, stirring occasionally. In a bowl, whisk the egg yolks, allulose, and vanilla flavor. Slowly pour the hot cream mixture into the egg mixture while whisking constantly to temper the eggs.
In a small bowl, whisk xanthan gum with about one quarter cup of the hot custard mixture until smooth. Return this mixture to the saucepan. Cook on low heat for five to ten minutes, stirring continuously, until thick and glossy.
Allow the custard to cool slightly, then pour it slowly over the cake, letting it soak into the holes. Refrigerate to set or enjoy warm for a softer texture.
Storage
Low-Carb Keto ‘Apple’ Poke Cake with Vanilla Custard stores well and actually improves in texture after resting. Cover the baking dish tightly or transfer slices into an airtight container. Store in the refrigerator for up to four days.
If storing individual portions, separate layers with parchment paper to maintain the custard topping. For reheating, warm gently in the microwave for short intervals to avoid overheating the custard. This cake can also be enjoyed cold straight from the fridge, where the custard firms up beautifully.
Freezing is possible, but texture may change slightly due to the custard. If freezing, wrap slices tightly and thaw overnight in the refrigerator before serving.
Variations and Substitutions
You can customize Low-Carb Keto ‘Apple’ Poke Cake with Vanilla Custard in several ways. Add nutmeg or ground cloves for a deeper spice profile. Swap almond milk with coconut milk for a richer custard.
For dairy free needs, coconut cream can replace heavy cream, and a plant based yogurt alternative can replace Greek yogurt. Keep sweeteners consistent to maintain keto macros.
You can also add chopped walnuts or pecans to the batter for texture, or sprinkle cinnamon on top of the custard before chilling for visual appeal.
Tips and Tricks
Always cool the apple cinnamon puree completely before adding it to the eggs to prevent curdling. Whipping the eggs and sweetener thoroughly is essential for a soft crumb.
Do not overbake the cake. It will continue to firm up as it cools and absorbs the custard. When poking holes, space them evenly to ensure uniform custard distribution.
Whisk xanthan gum separately to avoid clumps. Stir custard constantly over low heat to prevent scrambling. Patience here results in a silky smooth finish.
Notes
This recipe uses zucchini to mimic apples, making it ideal for keto diets. The vegetable flavor disappears entirely once cooked and spiced.
Net carbs are approximately 4 g per serving depending on portion size. Always verify sweetener labels to ensure carb counts remain consistent.
Using quality vanilla flavor and cinnamon makes a noticeable difference in aroma and taste. This dessert is rich, so smaller servings are satisfying.
