Ingredient Notes and Substitutions
For the full list of ingredients, please visit the recipe card below. Here is a list of the main ingredients along with any notes and substitutions.
Flax meal & water: The mixture of flax meal and water is essentially an egg substitute which helps bind the cake ingredients together. I recommend using flax meal from brown flax seeds rather than golden flax, the latter of which tends not to gel as rapidly.
Olive oil: This adds moisture and lightness to the cake and is an ideal choice over butter which will make the cake more dense and pound cake-like. Any neutral flavoured oil will work for this recipe in equal measure.
Whole spelt flour: this adds a nutty taste to the cake which is a wonderful compliment to the sweet berries. Feel free to substitute white all-purpose flour or whole wheat, or a 60:40 ratio of all-purpose flour to whole wheat flour if you prefer.
Almond milk: any unsweetened plant-based milk will for for this recipe; oat, almond, light coconut or soy.
Apple cider vinegar: this help create rise and lightness to the crumb when it reacts with the baking soda. Regular white vinegar will also work here if you're in a pinch.
Fresh blackberries: purchase the freshest, ripest blackberries possible. Blackberries are at their peak in August in the Pacific Northwest, but their season will depend on your particular geographical locationโthe take away is to choose them when they're in season. The more ripe they are, the sweeter and juicier they will be. Be sure to give them a good rinse and pat dry and remove any that are less than ideal specimens (store bought berries can be prone to mold spores; discard any are molding for obvious reasons). Any summer berry will work in this recipe, so feel free to experiment as the season allows.
Confectioners sugar: This forms the base for the glaze. It can often be referred to as icing sugar or powdered sugar depending on where you're from.
Lemon juice: this is used to add the zingy lemon flavour to the glaze. Lemon balances out the sweetness of the blackberries and sugar in this recipe.
Lemon zest: has the same purpose as the lemon juice, however, lemon zest is much more potent and lemony. Both are needed for this recipe.

How to make vegan blackberry cake with lemon glaze
For the full directions, please see the recipe card below. This is a brief synopsis of the steps required to make this recipe.
Step 1: generously grease a bundt pan, then combine the flax meal and water to allow them to gel . Next, add in the olive oil and sugar and mix well.
Step 2: Sift together the spelt flour, baking soda, baking powder, and salt.
Step 3: In a small bowl, mix together the almond milk, lemon zest, vanilla, and apple cider vinegar.
Step 4: Alternatively add the flour mixture and almond milk mixture to the flax meal, stirring between each addition until everything is combined. Add in the blackberries and gently fold into the cake batter until evenly distributed.
Step 5: Spoon the cake batter into the prepared pan and bake in the pre-heated oven for 50-55 minutes, or until a toothpick inserted into the centre comes out clean.
Step 6: Remove the cake from the oven and cool, in the pan, on a wire rack for 15-20 minutes. Gently run a thin spatula or knife around the edge of the cake (including the centre tube). Place the cooling rack on top of the pan and flip the cake over while firmly holding the rack in place. Once you feel the cake drop, gently lift off the pan. Cool the cake completely, about 3 to 4 hours, then gently transfer it to a serving plate.
Step 7: Make the glaze by mixing together the glaze ingredients.
Step 8: Drizzle the lemon glaze over the top of the cooled cake and garnish with fresh blackberries (optional).

Important Tips
This recipe works best in a fairly open Bundt pan without tight crevices. Because spelt flour contains less gluten than regular wheat flour, it can be more prone to breaking if youโre not careful. However, if give your pan a good greasing beforehand, you minimize the chances of running into troubles.

Storage Notes
Storage: the baked cake should be stored covered in the fridge and should last up to 3-4 days.
Freezing: to freeze this cake, it works best to portion the cake first and then wrap the slices tightly in freezer safe wrap and place in a freezer safe bag. The slices should last up to 3 months. Defrost the slices in the fridge before serving.

I went to the farmer's market on Saturday and saw some gorgeous blackberries. Hopefully they'll still have them on the market tomorrow, so I could by some and make your delicious bundt cake. I've already read the recipe on BAKED and it sounds wonderful. It would be my first planted-based cake! I really like that idea ... My first plant-based Blackberry bundt cake to invite friends over for coffee on Labor Day Weekend. That's a fanatastic plan!
Thanks for sharing and those gorgeous pictures,
Eva
That's wonderful, Eva! Let me know how you like it! And as always, thanks ever so much for your sweet support and feedback ๐
Another winning recipe. Only thing is the glaze didn't set the same as yours. The cake was cooled overnight and the glaze was mixed and added the next morning. But the cake soaked it up completely. Any idea why that might be the case? Anyway, it was delicious all the same and a big hit at the office. Thanks so much!
Hi Mel! I'm so happy you like my recipe ๐ I'm curious if it could be from the ambient room temperature? Sometimes, it helps to pop the cake in the fridge or freezer for a 15-20 minutes before glazing to help it set up.
