Free Keto Meal Plan: KETO DIET PLAN FOR BEGINNERS STEP BY STEP GUIDE
Preheat oven to 350°F (180°C).
Peel the fresh pineapple and cut it into thin rings of about 3 mm/0.1 inch thickness, using a sharp knife (remove the hard center part of each ring using a round shape. A ring is about 1.2 oz.
Pat dry each pineapple ring into some absorbent paper to remove extra juice that could release into the cake and make it too moist.
BOTTOM LAYER
Prepare the topping in a small bowl by beating softened butter and brown erythritol to form a creamy paste.
Use a silicone spatula to spread the creamy, buttery paste all over the bottom and sides of a non-stick 9-inch springform pan. Set aside.
Arrange the fresh pineapple ring all over the bottom of the pan and place a raspberry in the center of each ring. Set aside at room temperature.CAKE BATTERIn a large mixing bowl, using a manual whisk, beat eggs, erythritol, unsweetened almond milk, baking powder, salt, vanilla extract, pineapple extract, and melted butter. Make sure the melted butter is not too hot, or it can cook eggs and form lumps.Gradually pour the almond flour into the liquid ingredients and stir until it forms a thick, slightly grainy cake batter.Pour the cake batter into the greased pan.Bake cake for 40-45 minutes in the center rack of your oven. I recommend tempting the cake pan with a large piece of foil after 25 minutes to prevent the cake’s top from burning.After 30 minutes, insert a skewer in the center of the cake, and if it comes out with almost no crumb on it, the cake is ready.Cool the keto pineapple cake into the pan for 30 minutes, then release it on a cooling rack for at least 3 hours before slicing.When the cake has reached room temperature, you can brush a sugar-free pineapple syrup on top to make it shine!Slice into 12 even slices.
STORAGEStore the cake in a sealed cake box in the fridge for up to 3-4 days.Freeze cake slices in airtight zip lock bags or a box and thaw at room temperature the day before serving.NUTRITIONSERVING SIZE: 1 sliceYIELD: 12 slicesServing: 1sliceCalories: 271.7kcal(14%)Carbohydrates: 6.8g(2%)Fiber: 3g(13%)Net Carbs: 3.8gProtein: 7.7g(15%)Fat: 25.6g(39%)Saturated Fat: 6.8g (43%)Polyunsaturated Fat: 1.3gMonounsaturated Fat: 3.9gTrans Fat: 0.3gCholesterol: 66.8mg(22%)Sodium: 246.5mg(11%)Potassium: 22.7mg(1%)Sugar: 1.1g(1%)Vitamin A : 429.4IU(9%)Vitamin B12: 0.1µg(2%)Vitamin C: 0.3mgVitamin D: 0.4µg(3%)Calcium: 116.9mg(12%)Iron: 1.4mg(8%)Magnesium: 2.2mg( 1%)Zinc: 0.2mg(1%
