Blackberry Coffee Cake Muffins

Ingredients

Cinnamon Orange Streusel

56 g unsalted butter (4 tbsp.)
75 g light brown sugar (¼ c. + 2 tbsp.)
90 g all purpose flour (¾ c.)
¾ tsp. ground cinnamon
zest of ¼ orange

Blackberry Muffins

100 g granulated sugar (½ c.)
zest of ¾ orange
56 g unsalted butter (4 tbsp.)
1 egg room temperature
½ tsp. vanilla
120 g greek yogurt room temperature (½ c. + 1 tbsp.)
130 g all purpose flour (1 c. + 1 tbsp.)
1 tsp. baking powder
¼ tsp. baking soda
¼ tsp. salt
100 g blackberries* (¾ c.)

Instructions

Preheat the oven to 425°F / 220°C. Line a muffin pan with 6 parchment liners.

Cinnamon Orange Streusel

In a small bowl, melt the butter. Add in the brown sugar, flour, cinnamon, and orange zest. Use a fork to mix the ingredients together, then set aside. The streusel will seem super buttery & become a cohesive dough, but will be able to be crumbled by the time we add it to the muffins.

Blackberry Muffins

Mash the blackberries and set them aside.
Add the sugar to a medium sized mixing bowl, then zest the orange into the sugar. Use your fingers to rub the zest into the sugar.
Melt the butter, then mix it into the sugar. Then, whisk in the egg, vanilla, and greek yogurt.
Add in the flour, baking powder, baking soda, and salt. Use a rubber spatula to fold the mixture together just until the last streak of flour dissapears. If the batter is a little bit lumpy that's okay.
Add in the mashed blackberries, and fold the mixture a few times just to get some swirls of blackbery throughout the batter.
Now it's time to layer the muffins. Start by pouring ~2 tbsp. of muffin batter into the bottom of each muffin liner, then top each muffin with 1 tbsp. of streusel.
Distribute the remaining muffin batter evenly (~3 tbsp. / muffin), followed by the remaining streusel.
Bake the muffins at 425°F for 5 minutes. Without opening the oven door, reduce the temperature to 350°F / 175°C.
Bake for an additional 10-15 minutes, or until a toothpick inserted into the center of the muffins comes out clean.
Serve and enjoy!

I recommend fresh blackberries, but you can use frozen as well. Bring the frozen berries to room temperature, then rinse them off before mashing them. Note that your muffins will likely be *much* more purple, but will still be just as delicious!

You can omit the cinnamon if desired, and increase the amount of orange zest if you are looking for a more pronounced orange flavor.
