Keto Peach Melba Loaf Cake

With my birthday coming up, I wanted to create a cake that highlighted my favorite seasonal fruits: peaches and raspberries! This cake is so easy to make and decorate. No need to fuss with layers. It is baked in a loaf pan, topped with a delicious peach buttercream frosting and then decorated with fresh fruit. What a beautiful and delicious way to end the summer!

Keto Peach Melba Loaf Cake

Makes 12 servings

Cake Ingredients:

3/4 cup + 2 tablespoons coconut flour (96 grams)

3/4 cup erythritol-based sweetener (I used LaKanto Monkfruit sweetener)

1/3 cup unflavored whey protein powder 

1 tablespoon baking powder

1/4 teaspoon salt

4 large eggs, room temperature 

4 large egg whites, room temperature 

1/2 cup unsalted butter, melted and cooled a bit

1/4 cup unsweetened coconut milk (or low carb milk of choice)

1 teaspoon vanilla extract

1 teaspoon almond extract

3/4 cup fresh peaches, skins removed and diced

1/3 cup fresh raspberries, cut into small pieces

Peach Buttercream Frosting:

4 tablespoons unsalted butter, room temperature 

1/2 cup erythritol-based confectioners sugar (either LaKanto Powdered or Swerve Confectioners)

4 ounces full-fat cream cheese, softened

2 tablespoons sugar free peach preserves (or apricot, if you can’t find peach)

1-2 drops yellow or orange food coloring (optional)

Garnish:

Raspberries and peach slices to decorate

Directions:

1. Preheat the oven to 325°F. Line the bottom and sides of a large loaf pan with parchment paper and grease the corners or any place not lined with the parchment paper sling.

2. In a medium bowl, whisk or sift together the coconut flour, sweetener, whey protein powder, baking powder and salt. Set aside.

3. In a large bowl with an electric mixer, beat the eggs, egg whites and extracts until light and fluffy. Add the melted butter, coconut milk and beat on medium-low until just incorporated. All at once, add the dry ingredients and beat until well blended. Fold in the chopped peaches and raspberries. The batter will thicken up as the coconut flour absorbs much of the liquid, which is normal.

4. Spoon the batter into the prepared loaf pan and spread to the edges and level the top with the back of a spoon or small offset spatula. Bake for 50 to 55 minutes in the preheated oven until top is golden brown and firm to the touch. It’s always a good idea to test the internal temperature of keto cakes and breads to better determine doneness. It should read between 206 to 210°F.

5. Remove from the oven and let cool for 25 minutes in the pan. If needed, run a sharp knife around the insides of the pan and lift the loaf out using the parchment paper sling. Remove and discard parchment paper. Cool cake completely before frosting.

6. For the icing, put the softened butter in a bowl with the confectioners sugar and beat with an electric mixer until very soft and smooth. Add the softened cream cheese and beat again until thick and pale. Add the peach or apricot preserves for a fruity flavor, if you like, and add a drop or two of yellow or orange food coloring if you want to turn it a pretty peachy color. This frosting can be kept at room temperature for about an hour, or you may chill the icing until it has firmed up a bit or for longer storage. Return to room temperature and stir before spreading over the top of the cake. Decorate the cake with extra fresh raspberries and peach slices. (It’s best to do this just before serving because the peach slices can discolor if added too far in advance.)

Tips: Ripe peaches work best in this recipe. If your fruit is under ripe, try keeping it in a brown paper bag with a banana to speed up the ripening process. The unfrosted cake keeps for a couple of days in an airtight container. Use a serrated bread knife to slice.
