Blackberry Coffee Cake Recipe
This Blackberry Coffee Cake is my new favorite breakfast. It is moist and flavorful with a crunchy almond topping. It pairs perfectly with fresh berries and a good cup of coffee. This easy recipe is low carb, keto, gluten-free, dairy-free, grain-free, sugar-free, and Trim Healthy Mama friendly.

Cake for breakfast is one of the great pleasures in life. Whoever came up with coffee cake is a genius. Every good cup of coffee needs a bite or two of something sweet alongside. I know I’m not the only one who thinks that way.
This is based on my Cranberry Walnut Crumb Cake from last fall. I love that cake but cranberries scream fall to me and I wanted a springier version. You can use any berries you like in this. I enjoyed the blackberries but the batch I had did have extra large seeds. If that would bother you choose another berry instead.

Does Coffee Cake have Coffee in it?
Nope. My kids still can’t believe this. Coffee cake is called coffee cake because it goes well along with a cup of coffee. This Blackberry Cake is a traditional Coffee Cake that is lightly sweetened so it isn’t overpowering in the morning. But it is still sweet enough and enough of a treat to be a great dessert at the end of the day.

I try to keep my recipes simple, with the exception of a few fancy special occasion desserts. As far as homemade, from scratch, cakes go this one is very simple. You can just mix the batter in a bowl with a wooden spoon and then dump the crumb topping ingredients in the food processor and pulse. This is delicious even without the topping if you want to simplify it further.

What baking pan should I use?
Any 8 x 8 pan will work. But, isn’t my new glass baking dish pretty? I use 8 x 8 glass baking dishes several times a week so when I saw this one I had to have it. It’s a nice change from the two pyrex dishes I’ve been rotating between for the last 10+ years.

Blackberry Coffee Cake Ingredients:
Almond Flour – I’ve really come to prefer almond flour in baked goods. It gives a tender crumb in cakes, cookies, and biscuits.
Coconut Flour – Just a little bit of coconut flour goes a long way. Coconut flour helps to balance the oiliness of almond flour since it is naturally drier and absorbs more liquid than other alternative flours.
Sugar-Free Sweetener – I like to use a blend of xylitol, erythritol, and stevia in my recipes. You can purchase this pre-mixed from the Trim Healthy Mama website or mix your own according to my recipe. By using a combination of sugar alcohols and stevia you can use half the amount required of regular sugar. Since these sweeteners can be more expensive this helps with my food budget.
Coconut Milk – coconut milk helps keep dairy-free baked goods moist and tender.
Baking Powder
Vanilla – With the price of vanilla being astronomical I decided to try a Mexican vanilla extract and have been happy with the results. It is much much cheaper than other vanilla extracts. I got 5 oz for under $6.
Coconut Oil – I use refined or butter flavored coconut oil in recipes that I don’t want a coconut flavor like this Blackberry Coffee Cake.

How to make crumb topping
This topping is made in a food processor by grinding the nuts and then mixing them with oil and sweetener. Just top the batter with berries and sprinkle the crumbs on top!
Can I use other nuts?
Yes, you can use any type of nuts you like. I chose almonds for this recipe since they have a mild flavor.
Can I use other berries?
Yes, you can use any berries! The color of the blackberry juice seeping into the cake underneath is beautiful. My daughters love the color purple and this is a great way to get a naturally purple cake.

If wanting to just use raw cane sugar, would that still work? What amounts would you suggest?
1.5 to 2 times as much. The sweetener I use is sweeter than sugar.
We can not do coconut, do you think I could change the recipe and it still work out?
Do you need it to be dairy free?
It’s delicious!!! So juicy and soft and flavorful! Thank you so much for this recipe 🙂
I mixed 1/8 cup of stevia and 1/4 cup of xylitol for the batter and it’s perfectly sweet for me and my family. Kids love it:)
Looks amazing! Planning on making it for breakfast tomorrow morning. Just wanted to check what other sugar substitute would work since I don’t have the blend. I have xylitol and stevia and erythritol. Thanks!
You can make my sweetener with those three. It can substitute for gentle sweet. Joyfilledeats.com/sweetener
I have this in the oven right now for my birthday brunch on Sunday! (I made your cranberry walnut cake a few weeks ago and it was delicious.) Just a quick question in hindsight – did you use blanched almonds in the topping? (I went with raw un-blanched one’s, hoping they won’t get overcooked.)
I think mine were raw too. It should be fine 🙂
Coffee cake turned out great! Thanks!
I just bought a large bag of Raw Stevia and tried it out in a muffin dish. Horrible!!!!! I may have used too much. I’m wary about investing in more sugar substitutes, but do you think the stevia will work in your recipe
I personally do not like plain stevia. I don’t mind it in combination with xylitol and erythritol though. I’d recommend mixing it with a sugar alcohol to cut the bitterness. This is my recipe: http://www.joyfilledeats.com/sweetener
Yummm. Making this for a potluck. Can I use pecans or walnuts in place of almonds?
Yup!
I didn’t realize you meant canned coconut milk. I used Silk protein milk and it turned out great!
Can i use butter instead of coconut oil? I prefer butter in baked dishes and we’re not dairy free over here 🙂
Sure!
Can I use baking blend? Also almond milk for the coconut milk?
Baking blend should work. I’m not sure if almond milk would. I use the full-fat canned coconut milk. Almond milk has a much lower fat content.
CAN OR CARTON COCONUT MILK?????
Can
Well done on your restrained response to the above question, and for taking the time to share this lovely recipe…delicious!
I’m not sure what we did wrong but it ended up very dry and had no sweetness to it at all.
I’m happy to help you troubleshoot. Did you use gentle sweet? Are you sure you only used 1/4 cup coconut flour? Could you have forgotten an ingredient? This is definitely not dry. It is very moist. If the coconut flour measurement is off it can through off the whole recipe since it absorbs so much moisture.
Do you use can or carton coconut milk?
I used canned coconut milk.
This is delicious, dense and moist! We did a mix of raspberries and blackberries and it turned out great! My daughter loves this before school in the morning. It keeps nicely in the fridge for at least 3 days and is now in our morning breakfast rotation. Thank you!
This looks so delicious! Will it dry out if I bake it ahead?
Nope, it is very moist. Even after a few days in the fridge 🙂
