Why you will love this easy blackberry oat breakfast cake

What you will need to make this blackberry cake
Old fashioned rolled oats: Old fashioned rolled oats make this cake a little heartier. They are blended down to a flour, so the cakes texture is different from baked oats. You can replace it with oat flour.
Almond Flour: Almond flour adds to the structure and moisture of the cake.
Baking Powder and Baking Soda: The leavening agents used in the cake.
Salt: Enhances the flavors
Greek Yogurt: Adds moisture and a little protein to the blackberry cake. You can replace with a dairy free yogurt or sour cream.
Applesauce: Provides moisture and natural sweetness.
Milk of choice: Keeps the cake moist. You can use any milk you wish. Regular, almond or oat milk are all great choices. Just be sure to use one without any added sweetener.
Eggs: Provides structure to the cake.
Honey or maple syrup: A little honey or maple syrup add a touch of sweetness.
Olive Oil: Keeps the cake really moist. You can swap or avocado, canola or vegetable oil.
Vanilla Extract: Adds to the flavor of the cake.
Blackberries: Fresh blackberries give this cake a fruity flavor. I have only tested the cake with fresh blackberries but I believe frozen blackberries would work in this recipe. If using frozen, do not defrost prior to folding into the batter.
Almond Slices: Almond slices provide some extra flavor and texture to the cake. You can omit if you wish.
Powdered Sugar: A dusting of powdered sugar adds just a touch more sweetness to the cake. This is optional and you can skip this ingredient if you wish.

Tips and tricks
- The blackberries do sink a little while baking. To prevent this, you can toss them in some flour prior to folding into the batter (about one tablespoon), but this is completely optional. Just be sure to use a gluten-free flour if you need the recipe to be gluten-free. Personally, I just let them sink a little.
- Due to external factors, there is no one set bake time for this cake. Start low on the time and check on the cake. Remove from the oven just as the batter sets and a toothpick comes out clean.
- The powdered sugar gets absorbed into the cake after about 12-24 hours. Nothing to worry about! You can dust a little more if you want it to have that pretty snowy look.
- This recipe stays good for about a day or two on the counter but stores better in the fridge in a airtight container. It will last about 3 days in the fridge.
