Blåbærmuffins med streusel-topping

Instruktioner

1. Lav streusel: I en lille skål blandes 1/3 kop mel, 1/3 kop brun farin, 1 tsk kanel og 1/4 tsk salt. Skær det kolde, hakkede smør i blandingen med en gaffel eller dejskærer, indtil der dannes ærtestore krummer. Køl dejen ned i køleskabet, mens du forbereder dejen.
2. Forvarm ovnen til 190 °C. Beklæd to bageplader med bagepapir eller silikoneforme.
3. I en mellemstor skål piskes det bløde smør med 1/2 kop brun farin og 1/4 kop granuleret sukker med en håndmixer eller standmixer med padle. Pisk i 2 til 3 minutter, indtil blandingen er lysere i farven og let luftig.
4. Tilsæt æg og vaniljeekstrakt og pisk, indtil det er blandet og glat.
5. In a separate bowl whisk together 1 1/2 cups flour, 2 teaspoons baking powder, and 1/2 teaspoon salt. Gradually add the dry ingredients to the wet mixture and stir until just combined; do not overmix.
6. Gently fold in the fresh blueberries, using a spatula to avoid crushing them. If your berries are particularly large, quarter them first.
7. Using a 2-tablespoon scoop (or tablespoon for smaller cookies), portion rounds of dough onto the prepared sheet, leaving about 2 inches between each cookie. Using the back of a spoon, make a small shallow well on top of each dough mound.
8. Place about 1/2 teaspoon blueberry jam into each well and lightly swirl the jam into the top of the dough with a toothpick or butter knife to create a marbled effect. Do not mix the jam all the way through the dough.
9. Generously sprinkle the chilled streusel over each cookie and press gently so it adheres to the dough.
10. Bake for 12 to 15 minutes, rotating the pan halfway through, until the edges are lightly golden and the centers look set but still soft. Allow cookies to cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.

Troubleshooting & Consistency Tips

• Cookies spread too much: Make sure your butter is softened, not melted. Chill the dough 10–15 minutes before scooping if your kitchen is warm. Use properly measured flour—too little flour causes spreading.
• Streusel melts into the dough: Ensure the streusel butter is cold when you cut it in and keep it chilled until topping the cookies. If your kitchen is hot, return the sheet with topped cookies to the fridge for 5 minutes before baking.
• Blueberries burst and turn the dough blue: Fold berries in gently and consider tossing them very lightly in 1 teaspoon of flour before folding in. This helps stabilize them and reduces bleeding.
• Centers are underbaked but edges are brown: Lower oven temperature by 10–15°F (5–8°C) and bake a few minutes longer, or bake on a middle rack to avoid excessive browning.

Storage & Make-Ahead

Store cooled cookies in an airtight container at room temperature for up to 3 days. If you want to keep the streusel crisp, place a sheet of parchment between layers and avoid stacking more than two high.

For longer storage, freeze baked cookies in a single layer on a tray until firm, then transfer to a freezer-safe container or bag for up to 3 months. Thaw at room temperature; warm briefly in a 300°F (150°C) oven for 4–6 minutes to refresh the streusel, if desired.

Cookie dough can be scooped and frozen on the tray; once firm, store balls of dough in a sealed bag for up to 2 months. Bake from frozen, adding 2–3 minutes to the bake time and allowing an extra minute or two if needed.

Why This Recipe Works

Balancen mellem brunt sukker og granuleret sukker giver både fugt og en let sejhed – brunt sukker giver karamelnoter og mørhed, mens granuleret sukker hjælper med struktur og smørekontrol. Bagepulver giver løft, så indret forbliver mørt og muffinagtigt snarere end tæt. Ved at folde blåbærrene forsigtigt i, bevares deres form og forhindrer for meget blødning, mens den lille klat marmelade giver en koncentreret blåbærsmag uden at gøre dejen blød. Endelig tilføjer den koldspættede streusel en kontrasterende sprød tekstur og varm kanelsmag, der minder om klassiske blåbærmuffins.
