Instructions
How to Make Plum Coffee Cake Batter
- To make this simple gluten-free plum coffee cake, start by rinsing the plums under running water. Then, take a knife and cut each plum in half, running the knife all the way around the pit. Separate the fruit into two halves, one with the pit and one without. Remove and discard the pit.
- Next, take each half of the plum and cut it in half again, or into two wedges if the plum is large. Dice all of the plum wedges and place them into a large bowl. Repeat this process with the remaining plums.
- Now sprinkle the diced plums with gluten-free flour and make sure to coat them evenly. Set the plums aside for now.
- Preheat your oven to 350 ℉. Grease a 9-inch round springform pan with butter or coconut oil.
- In a medium glass bowl, sift together the gluten-free and almond flour. Add the rest of the dry ingredients to the bowl: baking powder, baking soda, Xanthan gum, and sea salt. Stir all of the dry ingredients together using a hand whisk until they are well combined. Set this mixture aside for later.
- Next, beat the sugar and eggs on high speed in a mixing bowl until they become foamy and pale in color. This should take about 5 minutes. Reduce the mixing speed to low and add the vanilla extract, melted and cooled coconut oil. Continue mixing for another minute.
- Remove the bowl from the mixer attachment and add the flour mixture to the wet ingredients in three separate additions. Gently fold in the flour after each addition to avoid deflating too many air pockets in the batter. These air pockets are important for achieving a fluffy texture in the cake.
- Finally, add ¾ of diced and coated plums to the batter and gently fold them in.
How to Bake Plum Coffee Cake
- Transfer the batter to the greased round pan that you prepared earlier. Sprinkle the remaining ¼ of the diced plums over the top of the batter.
- Bake the cake in the preheated oven for about 35 minutes, or until an inserted toothpick comes out clean. Once the cake is baked, remove it from the oven and let it cool in the baking pan for 5 minutes. Then, transfer the cake onto a cooling rack to cool completely.
- When the cake has cooled down to a warm temperature, sprinkle the top with organic powdered sugar. Slice the cake and enjoy!
