How to Get Tall Muffin Tops

Do not overmix

As most bakers know, mixing any batter that contains flour leads to the development of gluten. Gluten in flour is activated by the presence of water, and strengthened by physical agitation. Overmixing a batter basically causes these gluten strands to strengthen, which can lead to a tough, gummy batter. But it can also lead to it’s rise being inhibited. Strong gluten development will essentially hold down the muffin batter and not allow it to freely rise up in the oven.

Allow the batter to rest in the fridge

While recipe testing these buttermilk raspberry muffins, resting the batter was the biggest difference between beautifully tall muffin tops and flat muffin tops.

While it is important to not overmix and cause excess gluten development, the process of mixing the batter will always cause some degree of gluten formation. However, gluten is at it’s strongest immediately after mixing, and sort of loses it’s strength the longer that it sits and relaxes. This is where resting the batter comes in! Allowing the raspberry muffin batter to rest basically allows those gluten strands to relax, allowing the batter to rise up in the oven uninhibited!

I allowed my batter to rest in the fridge for 4 hours and received great results! You can, however, allow them to rest overnight as well! I simply made the batter in a bowl, covered it and placed it into the fridge for a few hours. Then when I as ready to bake, I used a cookie scoop to scoop the batter into the muffin pan. I was also careful about not deflating the batter as I scooped, as some of the leavening process has already begun to happen. Lastly, I filled each muffin line about 7/8 of the way full.

Bake at a higher temperature

By placing the raspberry muffins in a super hot oven, the muffins rapidly rise up, creating a taller muffin top! However, they only bake at this high temperature for a few minutes, because if we baked the raspberry muffins at this temperature the entire time, the bottoms and tops would likely burn before the insides were properly cooked – therefore the oven temperature is reduced to prevent burning and uneven baking.

How to make the Buttermilk Raspberry Muffins

1.Whisk together the dry ingredients: In a mixing bowl, whisk together the flour, baking powder, baking soda, and salt.

2. Whisk together the wet ingredients: In a separate large bowl, add the melted butter, sugar, eggs, sour cream, buttermilk, and vanilla. Whisk the wet ingredients together until they are well-combined and smooth.

3. Add wet to dry: Pour the dry ingredients into the mixing bowl with the wet ingredients. Using a wooden spoon, mix the batter together until it smooth and well-combined, but be careful not to overmix!

4. Fold in raspberries: Add the raspberries to the muffin batter, then lightly fold them in.

5. Rest the batter: Cover the bowl and place into the fridge to rest for about 4 hours.

6. Top with streusel and bake: Evenly distribute the rested batter into the cupcake pans, then sprinkle each muffin with the prepared streusel, then place into the oven to bake. Be sure to turn your oven down after 6 minutes!

How to make the streusel topping for the raspberry muffins

Making the Streusel for these muffins is a piece of cake! Simply throw the flour, sugar, and salt into a bowl and whisk together to combine. Then pour the melted butter over top and mix well with a fork until the mixture resembles wet-sand. This mixture then gets sprinkled over the muffins right before it’s time to bake!

Notes

† to measure flour correctly, use a spoon to scoop the flour into the measuring cup, then level off with a straight edge. Do not pack the flour into the cup, or scoop with the measuring cup straight from the bag/container. Alternatively, weigh the flour (1 cup = 120g or 4oz)
