Step 1

Soften or melt the butter, and use your hands to mix it with the brown sugar, flour, and salt. You should get the consistency that matches the pictures above – like small pebbles.

Step 2

Beat the cream cheese until smooth. Add egg and sugar; beat again until smooth.

Step 3

Preheat the oven to 425 degrees. Beat the butter and sugars together until creamed. Add the eggs, yogurt, and vanilla; stir until combined. Add the flour, baking soda, baking powder, and salt; mix until just combined. The batter will be thick. Fold in the frozen berries just before assembling the muffins.

Step 4

Line a muffin tin with paper liners. Press 1-2 tablespoons of batter into the bottom of each muffin tin. Flatten with the back of a wet spoon. Pour a spoonful of cheesecake mixture over the top. Cover with another 1-2 tablespoons of muffin batter. Sprinkle with streusel.

Step 5

Bake for 5 minutes at 425 degrees, then turn the oven temperature down to 350 and bake for another 15-18 minutes. Voila! Look at those beauties! You did it!
